Truth be told, Enid could have offered to reduce the amount I owed her by just a nickel, and I'd have jumped at the chance. My cock gave an enthusiastic twitch when she suggested I could settle my debt by fucking her.
The brief time I spent considering her words was more for show than anything else. I'd already made up my mind. Still, I let out a heavy sigh before I nodded and said, "Well, I guess that's fair, Enid."
"Good boy." Pointing toward her nightstand, she added, "There's lube in the drawer."
I knew I looked stupid blinking at her in confusion, but I wasn't sure why we needed lube. Paisley and I only used it for anal, and I was pretty sure Enid didn't want my dick in her ass. Then again, she was full of surprises.
Noting my puzzled expression, she explained, "Older women don't get as wet, so the lube will make sex more comfortable for me."
I still wasn't sure I understood. She seemed plenty wet while I was eating her pussy. Yet I hurried to do as she said. This wouldn't be any fun at all if Enid was uncomfortable.
Lube in my hand, I hesitated before rejoining her on the bed. "Uh, do you want me to get a condom from my apartment?"
She propped herself up on her arms, her legs spread wide. "No, handsome. I want you to come inside my pussy."
My cock now visibly jumped. Though Paisley was on the pill, I always used a condom. As absentminded as my girlfriend was, I didn't trust her to remember to take the contraceptive at the same time every day. And Paisley was fine with condoms; she said they didn't feel all that much different to her, and she preferred not having my semen leaking out of her after a fuck.
So the chance to fuck Enid bare excited me more than it otherwise would have. I was a little too quick, a little too eager, scrambling onto that bed and positioning myself between my elderly neighbor's thighs. She remained on her back, moaning faintly while she toyed with her nipples.
I got the sense that she enjoyed my guilt about betraying Paisley, and I decided to play into that. After all, the lady was forgiving a debt of three hundred dollars. Wasn't it the least I could do?
Meeting Enid's eyes, I released another sigh. "I think you're a gorgeous woman, and I loved going down on you. But this feels so wrong, like I'm cheating on my girlfriend."
"Well..." Enid drew out the word, as if she was pondering the matter. "If you're struggling with your conscience that much, Hank, you could always ask Paisley to come up with the remaining three hundred you owe me. Or..." She again spread her hairy pussy lips. "You could slide that cock right inside me. Paisley will never have to know you got rock-hard for a woman old enough to be your grandmother."
Though I winced at her words, I got busy applying the lube. An involuntary moan escaped me as I handled my cock. Fuck, I was already so hard and horny that I didn't know how long I'd last for Enid.
Finally, I brought my cockhead to Enid's opening. I'd actually begun trembling from excitement, and the moment I started easing my dick inside her pussy, I knew this was going to be heaven. She wasn't as tight as Paisley, but she was so warm! As her slick flesh encased me inch by inch, she let out a pleasured moan. Her eyes closed, the lids fluttering, and her lips parted.
"Ooh, Hank, yes! Give me that thick, hard cock!" Enid opened her eyes and flashed me one of those teasing grins. "You're good and worked up now, aren't you?"
"Yeah..." My answer sounded like a whimpering sigh.
Once I'd bottomed out, I took a few seconds to fully enjoy the sensation. I held myself above Enid, my hands planted on the bed on either side of her. Gazing down at her face, I was struck with the wild urge to kiss her.
"Fuck me," she whispered, then giggled like a far younger woman.
Tentatively, I began moving my hips. I knew Enid wasn't fragile, but I still wanted to make sure I didn't hurt her. "Is that okay?" I asked. "Did I use enough lube?"
She slid her hands along my skin. "It's perfect. You make me realize just how much I've missed cock."
Her dirty talk encouraged me to work toward a more intense rhythm. Soon, I was rutting away, my groans nearly drowning out hers.
"How's that pussy feel?" Her question had a taunting edge.
"You feel so fucking good!" Each time I drove myself all the way inside her cunt, the connection of our bodies sent a jiggle through her large breasts.
"Does Paisley get you this excited?" Enid picked up her right tit and brought the nipple to her lips. The sight of her sucking it caused my balls to tighten.
"Oh God, I never imagined you were so dirty, Enid!" I was breathing faster now as my cock pumped in and out. Her cries increased in strength and volume, just as my dick swelled more within her warm walls.
I began struggling to hold back, and when Enid reached between her legs and rubbed her clit, I prayed she was close to orgasm. I'd feel like a complete failure if I came first.

Maybe Enid sensed how on edge I was, because she said, "I'm almost there! Don't stop."
"Please, Enid! I can't..." The room was warm, and I'd grown sweaty from my own heat. Even though I slowed down a bit, trying not to shoot my load, my effort was clearly enough.
She came again, the orgasm rippling through her body. Her eyes rolled a bit while her nails dug into my skin. I thought I was home free; my helpless grimace turned into a grin of triumph.
Then Enid gave me a hard stare. "Don't you come yet, Hank. Let's try it another way."
"Ah, fuck!" I yelped. Still, I slid out of her and rested on my knees. Trying to catch my breath, I looked down at my cock, which swayed from the force of my pulse.
I watched as Enid rolled onto her stomach and then positioned herself on her hands and knees. Immediately, my eyes locked on her ass. Those large cheeks weren't tight and muscular like Paisley's, but I couldn't resist squeezing them.
My enthusiasm made Enid laugh. "You naughty boy!"
"How's this for naughty?" I leaned forward and gave her right buttock a playful nip. I even went so far as to spread her open in order to get a glimpse of her rosebud. The filthy impulse to lick it almost overwhelmed me.
Enid threw her head back, trying to toss her disheveled hair out of her face. I decided I would help by gently gathering up those long, gray strands in my fist. With my other hand, I brought my cockhead to her entrance.
"Fuck me!" she cried.
I didn't want to pound away at her, the way I sometimes did with Paisley when she was in this position. Instead, I pumped my hips with shallow thrusts. The bed squeaked beneath us, and I only wished I could see Enid's tits swinging.
"Oh, dear God, I'm gonna come again! Deeper, Hank! Harder!"
Releasing a growl, I pulled her head back just a little more. "Gonna fill your pussy, Enid!" My body was now slapping against hers.
Another powerful spasm overtook her then, rendering her unable to speak. My teeth were clenched as I watched my cock wildly thrusting inside her cunt.
"Come for me!" she finally managed to say. "Give me that creampie I've been wanting!"
Enid's filthy talk completely undid me, when I was already desperate to let go. My muscles tensed, and I let out a shuddering breath just before emptying my balls into her. She cried out in response, urging me to give her every drop.
Once I was totally drained, I remained buried inside her pussy for a long moment. Tenderly, I stroked her back. It was then that I realized how easy our fucking had been. This woman let me know exactly what she wanted, and she was blatant in expressing her pleasure. Paisley sometimes left me wondering if she was truly satisfied. With Enid, I had no doubt.
Finally, I withdrew, and when Enid again lay down on her back, I collapsed at her side. I felt like I'd fucked all the tension out of my body.
Extending a hand, she caressed my cheek. "Now, that wasn't so bad, was it?"
Turning my face toward her, I smiled. "You're an amazing woman, Enid."
She propped herself up, then slowly lowered her lips to mine. I didn't try to stop her, or say this wasn't part of the deal. No, I readily allowed her to plant a kiss on my mouth. In fact, I slipped my arms around her while our tongues met. My shame had evaporated at this point, and not even post-nut clarity could bring it back.
"Now that you don't owe me," Enid said, her gaze bright and playful, "I might have to pay you to keep coming around."
Brushing tousled strands of hair back from her face, I said, "No payment necessary."
*****
After that afternoon with Enid, I couldn't reconnect with Paisley in any way. In the past, I was usually the one to initiate sex, but I stopped doing that. When I kissed her, I had flashbacks to my upstairs neighbor playing with her tits, or on her hands and knees, offering her pussy to me.
Sexual frustration finally drove my girlfriend to make the first move, yet I couldn't get fully hard from her blowjob. In exasperation, she lifted her head to demand, "What the hell is wrong with you, Hank?"
I couldn't keep pretending. "I don't want to be with you anymore," I blurted out. "We're different people who want different things."
She sat up, her eyes wide with shock. "Are you fucking kidding me? Have you met someone else?"
"Yes," I immediately responded.
"You asshole!" Scrambling away from me, she rushed to get dressed. I silently listened to all her swearing and insults. Before, they would have cut me to the quick, but not any longer. Not since Enid.
I waited until she was almost out the door before telling her, "Don't hit anything on your way out."
"Fuck you, Hank!"
I watched from the window, making sure she didn't do anything stupid while leaving.
And once she was gone, I headed upstairs to Enid.
