Through my euphoric haze and over the roaring in my ears of the orgasm flooding my pants with cum, I heard Nate respond. I was gasping, trying to keep quiet to avoid attention in the noisy dining hall. I opened my eyes to see Nate focused entirely on Gwendolyn as he answered my invitation.

"I'd be honored," he said, a glint in his eye as he spoke quite solemnly. "It would be a pleasure to fuck your beautiful girlfriend."

Gwendolyn held his gaze in silence while her hand was working to open my jeans and reach into my boxers. She turned to me as she brought her hand back out, up to my lips, shining with my shimmering slime.

"Thank you, Gwendolyn," I said. I licked her hand and sucked her fingers clean, drawing the notice of one or two nearby diners. It was good. It tasted like devotion.

Nate got it. "What a good obedient boy you have!" he said admiringly. "You've trained him very well!"

Gwendolyn laughed happily. "Not really. I've only had him five days," she said. "He's just a really sweet boy."

She retrieved her hand and dried it on her shirt. "And when we met I found out he already worshipped me. He had been for years."

"No, you have trained me, Gwendolyn," I said. I wanted to give her credit. I needed Nate to truly appreciate her magnificence. "I worshipped you, but you taught me how you wanted me to express my worship and how to please you. You made rules for me and you rewarded my obedience."

Nate agreed. "It looks like you've trained him to eat cum," he said by way of evidence. "And being your cuck? That wasn't his idea was it?" He raised an admiring eyebrow. "You're not giving yourself enough credit. I sensed your power right away."

Gwendolyn suddenly appeared taller, looking regal. She addressed Nate as if on high. "Are ready to submit to my power?"

"Yes, Miss Gwendolyn," Nate said with palpable excitement. "Command me."

Gwendolyn stood and took my hand. "Come with us," she said.

The three of us walked together to my car. Gwendolyn held my hand all the way, but then she sat in the back with Nate while I drove.

"So this is Dr. Metzler's house?" Nate said as we climbed the stairs to Gwendolyn's attic lair.

I undressed on the landing and knocked for admittance according to protocol. Nate had entered with Gwendolyn and was still fully dressed when he opened the door for me. Gwendolyn was sitting on the end of the bed, also still dressed.

Nate looked me over as I walked in. I was self-conscious. My cock had deflated, but began to swell again as I stood before Gwendolyn, awaiting instructions. This was new territory for me. For both of us. I stood silently with my hands behind my back.

She could sense my apprehension, and its battle with my excitement. "It's going to be okay, baby," she said, stroking my flank gently, the way you might calm a nervous colt.

That helped. And so did her cat, Toby, who crawled out from under the bed and wrapped himself around my ankles, clearly preferring me over Nate.

"Put this in your mouth." She held the butt-plug out to me. I had forgotten it. She had not; she had removed its packaging, intending to put it to use.

I got it good and wet, knowing where it was going.

"Good boy," she said holding out her hand to retrieve it. she patted her thigh. "Lie down."

I lay myself over her lap. I felt her spread my cheeks. My anus felt the exposure to the cool air and then the pressure of a wet finger, followed by the cool steel of the plug, opening me and then sealing itself inside. It made my cock twitch and release a bead of pre.

"Good boy," she said again. "Isn't he pretty?" She patted my jeweled ass playfully.

"Very fetching, Miss," said Nate. It seemed an odd word choice, but he sounded sincere. I had a fleeting thought: does he want to fuck me?

"Okay, stand up," she said, giving my ass a proprietary slap.

Then she said, "Come here," to Nate.

He stood facing Gwendolyn beside me.

"Mike will undress you. Raise your arms."

I turned and pulled his polo up and off. His chest and abs were trim and muscular, his shoulders broad and shapely. He was just a tiny bit shorter than I, but he still had shoes on. I knelt and untied them, Nike running shoes. He lifted each foot in turn, assisting me in removing them and his socks.

I tried not to think. I focused on the task at hand. For Gwendolyn, I said in my head, repeating it like a mantra. It kept me calm. I would do whatever she wanted. I trusted her.

The smell of his feet was perceptible but not overpowering. It was different from hers, that I loved to worship. I stood to unbuckle his belt. I unbuttoned his jeans and pulled down the zipper. His masculine scent was present. I was able to ignore it; it had none of the allure that Gwendolyn's scents affected in me.

I pulled down his jeans and underpants together. He shimmied his hips slightly to help and stepped out of his pants as I held them, kneeling. His cock was semi-hard, hanging over his loose balls. It was thicker than mine and uncircumcised.

"Feel his cock," said Gwendolyn, her voice thick and low. "Get him hard for me."

I wrapped my hand around it, feeling it stiffen and rise. I stroked it. It grew to a length comparable to mine, which had also risen, but looked straighter and blunter, with its foreskin hiding the head.

"Stand up," she told me. I stood, turning to face her. She took my cock and, saying "Turn," she turned me to face Nate.

She pressed our cocks together, squeezing them and stroking them briefly, stretching her fingers to keep them in contact. It was bizarre to see the two cocks together like that, especially because it felt so erotic.

Gwendolyn stood up, letting go of our cocks. She put her hands on either side of my face and pulled it into a deep, soul stirring kiss. Then she whispered hotly in my ear.

"Thank you, baby," she said.

Then, breaking our embrace, she issued her commands.

"Sit," she said to me, indicating the chair that had been placed beside the dresser, the same spot from which I had watched her masturbate a few nights before.

"You can touch yourself, but no cumming."

I left the two of them at the foot of the bed and took the spectator's seat, feeling the plug move in my ass as my weight settled.

"Undress me," was her next command.

Nate proceeded slowly, gently, as if unwrapping a precious gift and wanting to preserve the paper. He unbuttoned her shirt, slowly revealing her perky breasts. He paused to cup them in his hands , brushing her stiff nipples with his thumbs, eliciting a sharp gasp, before he slipped her shirt off her shoulders and let it drop to the floor.

He knelt and gripped the waistband of her leggings and peeled them down in one smooth motion. Gwendolyn lifted each bare foot in turn and Nate freed them, tossed the leggings aside, and reached for the waistband of the thong, the only cover remaining.

This he slid it down her shapely legs slowly, taking time to experience their elegant contours and the smooth texture of her skin, while he breathed in the heady aroma emanating from both the sodden fabric and her wet labia. Or so it seemed to me from my observer's seat.

When Gwendolyn stepped out of the skimpy thong, Nate tossed it to me. Perfectly thrown, it landed on my lap in puff of redolence. I brought it to my nose with a deep sigh. The exotic perfume of her aroused and ready pussy was not just familiar, it was deeply moving, reminding me of everything I cherished most.

Still on his knees, Nate had grasped Gwendolyn's round ass cheeks with both hands and was pressing for entry to her pussy with his tongue and lips. Gwendolyn fell back on the bed and pulled Nate up by his arms, so that his oral attack was redirected to her breasts.

"Fuck me, Nate," she said fiercely. "Put it in me now!"

It was clear she had no interest in, nor need of, foreplay. The undressing had been more than enough. Nate took hold of his cock and, with practiced expertise, aligned it perfectly with her entrance and plunged it in, parting her passion-slicked lips and stretching her vaginal walls exquisitely, judging by her nearly pained expression and ecstatic moan.

Two thirds of his thick length having sunk into her on the first thrust, his second lunge completed the course, lodging him inside her, balls deep. She rocked her pelvis and wrapped her legs around his waist, locking him deep inside her. I watched her face reflect the ecstatic joy of being fully stretched and filled.

And then, as if by a silent signal, they began to move in synchronicity. Barely perceptible at first, the gentle rocking became a rhythmic thrusting that grew into a pounding, slapping, smacking, grunting, heaving, and moaning fuck for the ages. It was athletic and balletic, combative and harmonious. And it continued to build. It grew until it reached a climax. A scream, a sound I had never heard from Gwendolyn before, pierced the room, and all four limbs spasmed and went limp.

"No, don't stop," she said breathlessly, as soon as she was able.

Nate had held her fully impaled while she thrashed. He began moving in her again, this time accelerating more quickly, but with less collaborative effort on her part at first, until another orgasm began to surge inside her.

Then she raked her nails down his back and sank them into the cheeks of his ass, pulling him into her as if she could make him go deeper.

"Yes, yes, yes, yes,' she repeated, punctuating each of his thrusts with affirmation. She was wiggling her ass in ways that made each of his thrusts impact the deep reaches of her fuck tunnel in a different spot, at a different angle. I could tell by the ragged flexing of his muscular back and ass, that he was on the edge.

"Cum in me, Nate! Fill my pussy with your cum!"

He did. With a deep guttural roar, he came, thrusting deep and pinning her deep into the mattress. I could see his ass and the root of his cock contract. I could have counted the number of ropes of cum he shot into her womb.

And she came too. I could see the orgasmic spasms that shook her as if in direct response to the force of his ejaculate. Nate collapsed, his head resting in the crook of her neck, and Gwendolyn too lay limp, sated and spent.

I had very nearly come just watching them, mostly watching Gwendolyn's face. Her pleasure was palpable, as if my brain could receive the neurotransmissions from the pleasure centers in hers. It was such a deep connection that, rather than feeling jealous, my feelings for Nate bordered on gratitude for the pleasure he gave her.

When they had regained their senses and disentangled their sweaty limbs, Gwendolyn called me.

"Come to me, Mike," she said. "Nate, trade places with him."

The smell of sex filled the room as the couple disengaged. I stood beside the bed as Nate took my seat. His cock was drooping and glistening, a hint of what lay inside of my well fucked girlfriend.

Gwendolyn took my hand. I bent to her and kissed her lips. Her face was shining with joy and sweat. I kissed her forehead, tasting her salt. I kissed her cheek and her mouth again and nuzzled into her neck where her sweat was collected by her collar bone. I drank. She spoke as she ran her fingers through my hair.

"That was so good! Did you see?"

"Yes, Gwendolyn. It was beautiful. You looked glorious!" I spoke while nuzzling down her sternum, into the valley between her breasts.

I licked the sweat off her skin under her boobs and dipped my tongue into her navel. The aroma of stewed pussy was now wafting to the forefront of my consciousness, pervading my senses and calling to me.

Her hand in my hair may have encouraged my descent to her fragrant nethers. In any case, it didn't hinder me. I repositioned myself between her splayed knees to resume my pilgrimage, kissing and licking her smooth, toned thighs on my journey northward toward the temple of her sex.

"Mmm," she purred as I teased her sensitive inner thighs. "Mmm, my good, good, boy," she murmured dreamily as I reawakened her desire.

I was nearly overwhelmed by the fumes emanating from inside her, where the hot punch of blended fuck juice was brewing and stewing. Cum! Lots of it. It filled me with desire. I was suddenly fixated on the idea of consuming it. I needed to taste it.

My tongue parted her lips eagerly.

"Yes, baby, clean my dirty pussy!" said Gwendolyn, gripping my hair more firmly now, pulling me into her heat.

I slurped as I delved into her sopping slit, extracting gobs and globs of soupy slime. It tasted like acquiescence. I swallowed it all, mouthfuls of it. The acrid, salty flavor grew on me while the texture reduced me to a primal state of greed, as if my sustenance depended on it.

"Mmm," I moaned as I feasted eagerly at her trough.

"Yes, baby," said Gwendolyn. "You like it, don't you? It's your reward. For being such a good boy today. So obedient!"

Her words filled me with sweet delight. A feeling of vindication washed over me, a soothing wave of peace and gratitude. I had to be the luckiest boy in the world!

I licked my lips and dove back in, digging as deep as my tongue would go and sucking to coax out any remnants of Nate's rich cum. I had already swallowed so much! Now the flavor of the juice and its silky texture were pure Gwendolyn. I had cleansed her.

And yet, oddly, perversely, I missed the demeaning flavor of Nate's cum, the proof of my abject submission to Gwendolyn's will. I inserted two fingers into her vagina, to reach deeper, in search of any morsels I might have missed.

Gwendolyn moaned and rocked her pelvis. I curled my fingers forward into her most sensitive spot and sucked her swollen clitoris. She reacted immediately, arching her back and coming yet again.

"Ohhh, yes, baby, yes!" she shouted as she mashed my face into the flooded folds of her swollen cunt. Then, she pushed me away.

"No, no more baby. It's too sensitive now."

She reached her arms out to me. "Come here, baby," she said.

I crawled up on the bed beside her. My hard cock grazed her hip. I kissed her. Her mouth was hungry. She savored her flavor on my lips, my tongue, the inside of my mouth.

"Mmm, I taste good," she murmured. "All clean, now." She pulled her head back to look in my eyes.

"You really are my good boy, aren't you, baby?" she said, with a note of admiration, as if I had accomplished something brave.

"I want to be," I said, choking up a little. "That's all I want."

"I know you like cleaning my pussy. Did you like eating Nate's cum?"

"Yes, Gwendolyn," I answered soberly. "I didn't think I would, but I did."

"Did you like the way it tasted?"

"I don't know. It was all mixed up with your pussy juice, and that's my favorite taste," I said.

"Would you like to taste it by itself, Nate's pure cum?" she asked softly.

I was a little taken aback, but I knew it was something she wanted. And if were honest, I felt I needed it, like when I was eating it from her pussy.

"Yes, please, Gwendolyn," I said. My head felt light; I was almost dizzy.

"Go clean his cock, baby," she instructed me. "Thank him for fucking me so well and clean him up. Then you may ask him for permission to suck him off." She put her palm to my cheek tenderly. "Can you do that for me, baby?"

"Yes, Gwendolyn," I said. I pressed my cheek into her hand.

Then I went to where Nate was sitting and knelt between his feet. He had opened his legs to give me access to his limp cock and balls.

"Thank you, sir," I said formally, "for fucking my girlfriend so well and so thoroughly. It was a privilege to see it."

"You're more than welcome, boy," he replied kindly. "She is a magnificent creature. You must be very proud to serve her."

"Oh, yes!" I enthused. "I am a very lucky boy!"

Leaning in, I was enveloped in the scent of cum, pussy, sweat, and ball musk, a heady concoction, powerfully compelling, evoking my subservience. I was unsure how to proceed. I had been told to clean him. Gwendolyn had told me to. But I didn't feel it was my place to take liberties without his consent.

"I will clean you now, sir, if I may," is what I deemed appropriate.

"Help yourself, son," he said with an encouraging smile.

I bowed my head to take a bold, broad stroke with my flattened tongue fully extended, starting beneath his hairy balls, up to the root of his cock, which obliged by filling out and rising just enough for me to lick it to the tip.

It tasted wonderful. Salty and tangy, the flavor, blending with the masculine musk of his sweaty crotch, made my mouth water while reinforcing my servility. I swirled my tongue around the tip of his cock that peeked out of his tightening foreskin, before I rooted under his balls again and licked off the dried cum on his hairy inner thighs.

When I went up his stalk again, it was with lips engaged. I tilted my head to add suction as I kiss-sucked my way to the top, which had gained altitude. His cock was now standing tall and thick and its head was now stretching the limits of its sheath.

I swirled my tongue around it again and this time I was rewarded with the clean, fresh taste of precum collected there. I opened my mouth instinctively and engulfed his cockhead, sucking for more of that sweet taste, suddenly needing it.

Oops! I stopped as soon as I felt his girth stretching my lips.

"Please, sir, may I suck your cock?" I petitioned humbly, with the realization that it was not precum I craved, but his hot, thick, white, sperm-cum.

"Can you take it all?" he asked sternly.

"I... I don't know, sir. I will try," I replied hopefully. Surely he wouldn't deny me!

"Will you swallow all my cum?" was his second proviso.

"Oh, yes, sir!" Of this I had no doubt. I had eaten cum before, my own and Anselm's, a man I hadn't met, but this would be the first time taking it from the source.

Something in the way I approached him to take him in my mouth again must have tipped him off.

"Have you sucked cock before?"

"Uh-uh." I managed a negative motion of my head with my mouth crammed full of cockhead. There had to be another half-foot remaining, and I was already near gagging.

"I'll help you," he said, resting a steadying hand on top of my head.

He pressed gently, pushing his cock into the back of my throat. I started to panic as my gag reflex kicked in. He allowed me to ease back a few millimeters. I was able to apply suction and use my tongue on the underside, coaxing his delicious precum out. My mouth flooded with saliva.

"Good. That's good. You're a natural," he said.

I was mollified and I relished the satisfaction of sucking him, like nursing on a gigantic teat. But still, I was determined to throat the beast.

"Just relax," he instructed. "Breathe through your nose, deep and regular. We'll take it slow and easy."

His voice calmed me. He repeated the pressure. I felt the blunt end of his cock push against the back of my throat again. I took a deep breath through my nose. It kept the panic at bay. I discovered that I wasn't going to suffocate after all.

A slight push further and I discovered that the back of my throat wasn't a wall, as it had seemed. It could yield. It could open, like a portal. It was designed that way, to allow entrance to my alimentary tract, I reasoned, realizing that I would starve if that weren't true.

I felt him, I let him, push in a little further. But this was no morsel. It had to be broader than my esophagus itself. How could it fit? Would it stretch? He went deeper yet. I kept breathing. Of course it would, I reasoned. I had seen sword swallowers and fire eaters. I had watched porn actresses.

I kept breathing. There was something satisfying in the yielding, in the stretching, in overcoming the instinct to retch and expel the invading monster. My eyes teared up. My face throbbed. But I prevailed.

I felt his cockhead go past all the constricting obstacles. Was it in my esophagus now? All I knew was that I was not choking, I was not gagging, that instead I felt a tight fullness where all the resistance had been. I opened my eyes; more than half of his length was inside. It was with a great sense of pride that I pushed my head down further and took all of him.

I glanced at Gwendolyn, my audience and the purpose of my act. Her eyes were shining, her legs were spread, and her hand was a blur of motion, strumming her pussy like a banjo.

I watched her as she watched me raise my head, bringing my lips to the tip of Nate's drooling cock. I nibbled and sucked, I tasted his juice, and I went down again, pushing through the choking point and all the way down. I swallowed, feeling my throat muscles massage his shaft.

"Ugh, yeah!" he growled lustily. "Doing great, buddy!'

I bobbed my head, setting a rhythm, and punctuating it with variations: a swallow here, a tongue-swirl there, until I felt him getting frantic. Then I picked up the pace, fucking his cock as if my mouth were a pussy. The friction in my throat and on my lips was tantalizing.

And I watched Gwendolyn. When Nate started to buck and shouted, "I'm going to cum!" I raised my head so that just the tip was in my wide-open mouth, so that Gwendolyn could see it.

She watched the ropes of cum shoot into the back of my mouth and flood my tongue.

She came, joining his orgasm, making me equally proud, as I counted six, seven huge spurts of hot creamy cum, filling my mouth.

I used my hand to squeeze the last of his ejaculate onto my tongue, holding his full load in my mouth. Then, facing Gwendolyn, who was still heaving in the throes of orgasm, I made a show of swallowing.

"Mmm-mmm," I yummed in unfeigned satisfaction as I ingested the huge load and smacked my lips. It tasted like victory.

"Thank you," I said to Gwendolyn, knowing that Nate would assume I was thanking him. Gwendolyn gave me a special smile.

Nate said, "You did real good, Mike. That was awesome!"

And to Gwendolyn, he said, "You should be very proud of your boy. He's a good one. Very special!"

"I know!" said Gwendolyn. "I'm going to marry him!"
