“Paul, I swear that guy’s checking out your ass!”

I followed Sarah’s eyes across the gym to where a young Black man of about our age was watching us train.

"He’s checking out your ass, babe,” I replied, “along with every other guy in here.”

Sarah’s ass was the stuff of legend. She was the gym’s reigning ‘Rear of the Year,’ and that was no mean feat, as the place had more than its fair share of bubble-butt snowbunnies. My peach bottom attracted lots of admiring glances too, and we both loved to flaunt our bodies in matching ‘sprayed-on’ booty shorts and crop tops.

“He’s cute, isn’t he?” She flashed him a flirty smile. “Let’s ask him whose ass he prefers.”

“Sarah!” I hissed, but it was too late. She’d hooked him with her smile, and he was coming over.

To be fair, he was cute and built too, hard and lean, the muscles accentuated by his mahogany skin tone.

“Hello handsome, so come on then, whatcha think—who’s got the best ass?”

He paused for a minute and then broke into a chuckle. “Actually, to tell the truth, I was trying to decide if you two were brother and sister or just good friends.”

Sarah giggled and touched his bicep. “We’re married!”

“Married, seriously?” his eyes darted towards me and down to the little bulge in my shorts. “I assumed he was…”, he tailed off.

“Assumed he was gay?” Sarah finished his sentence, then, without waiting for a reply, “Paul’s bi.”

“Sarah!” I protested, but she just gave me a pouty smile and cocked an eyebrow.

Although at 18 she was a year younger than me, Sarah was sexually precocious and very much the leader in our relationship. She made no secret of her voracious appetites and eclectic tastes, and she’d gradually helped me understand that what other people saw as kinks and fetishes were actually exciting and natural aspects of our open-minded and uninhibited sexualities—aspects that we’d be exploring together.

‘Encouraging’ my embryonic bisexual fantasies was a particular delight of hers.

He took a moment to digest the revelation; “Oh, okay…” his voice was as deep and as rich as his complexion, with a hint of the Caribbean. “I’m Marlon, by the way; you guys seem a very friendly and fun-loving pair.”

“Nice to meet you, Marlon.” Sarah stroked his bicep; her voice had become sultry and her manner suggestive. “Yes, we are. What about you? Are you the fun-loving type too?”

“Hell yeah,” he said, taking the hint and letting his hand drop down to the rear of Sarah’s little hotpants, and he again eyed the tiny bulge at the front of mine. “Paul, you look cute in those tiny booty shorts, I must say.”

“Thank you big boy”, I said, coquettish and playfully camp, “I love to show off my little boy bulge.”

“Yeah, I can see that, you little tease," and he gave my rump a solid spank with his heavy hand.

“Look, Marlon, we’re done here,” Sarah chipped in. “How about we continue this back at our place? We’re just around the corner.”

“Yeah, let’s do that.” Marlon was as horny as we were.

Back at the flat, the intimacy of it being just the three of us made Marlon and me a little shy. Sarah broke the ice.

“Come on then, you two, don’t be bashful, start with a little kiss and see how that feels.”

I took a demure step forward and looked up into his eyes. There was hunger there, and passion.

Our lips touched, tentative at first, then stronger. His muscular arms enveloped me as his tongue pushed assertively into my mouth, circling, exploring, and then thrusting into my throat, the message clear, our roles defined.

I felt him rising and hardening, massive and powerful between my legs, and I let out a little sigh of pleasure.

“Oh my God, boys, have you both gone gay on me?” Sarah was watching us kissing. We were both a little embarrassed, caught up in the moment, but Marlon soon regained his composure and confidence.

“Oh, are you feeling neglected, peaches?” he said, turning towards her.

“Oh my goodness, Paul, have you seen this?” she took hold of an almighty erection through his thin nylon shorts. “He’s huge!”

Marlon pulled her roughly into his arms and claimed her mouth as he’d claimed mine.

I stripped off my sissy shorts and top, letting my tiny boybit bounce up fully erect, then dropped to my knees, pulled down his shorts, and eagerly thrust my face between his butt cheeks as his erection sprang up hard between Sarah’s legs, crashing into her mound.

I quickly went round and pulled down her hotpants so she could feel his cock against her bare cunt. He was so long that a good 5” of it protruded from between her thighs for me to suck from behind as they continued their passionate snogging.

Sarah must have heard me greedily feasting on Marlon’s monster BBC, and she soon came down to join me.

“Paul, I love to watch you sucking cock; you look so pretty with a throbbing black pipe between your lips.” I put on a slutty show for her, lollipoping his bulbous mushroom head while looking up at him doe-eyed. Her mouth was watering, and soon she grabbed his thick root and pulled him away to taste it for herself.

Sarah and I both had a strong natural attraction to Black men and had met enough of them to know that the ‘rumour’ about them being well-hung was actually an undeniable fact. Even so, Marlon was particularly impressive. Nine inches, a beautiful upward curve, and his shaft a rough landscape of raised and swollen veins.

Sarah was a very accomplished cocksucker, and she was soon deep-throating our new friend as I sucked his balls. It wasn’t long before he started to tremble and shake as his climax approached. He pulled out of Sarah’s mouth, his huge cock dripping strings of her drool, and with a ferocious cry, unleashed a powerful spurt of his seed directly into my face. One second later he redirected his aim, and the next jet splashed into Sarah’s eyes and hair before he came back to me and shot the next ropes of cum into my open mouth. He continued like this, painting both our faces with his thick cream, until finally his orgasm abated.

“Fuck me,” said Sarah, wiping the sperm from her eyes, “was that a week’s worth, you stud?” “Nah,” he said, “about two hours worth.”

I sucked Marlon’s dick clean as his erection slowly subsided, and Sarah suggested we go through to the bedroom. Once there, Marlon threw her onto the bed and dived between her legs.

“Damn, girl, you’re dripping.” The Black king kissed and licked at my young wife’s molten pussy. He was on all fours with his muscular ass in the air, and I took this as my cue to move behind him, spread his cheeks, and resume my oral worship of his anus. From this angle, I had full access to tongue-fuck him deeply and was soon swirling three inches of my tongue inside his gaping manhole.

Crude and brazen sex sounds filled the room. Marlon slurping on Sarah’s cunt, her moans of ecstasy as her orgasm approached, and my noisy slobbering over his lush ass.

As Sarah started to cry out that she was cumming, I reached through to squeeze his giant meat, which was fully erect again already.

This time it was his turn to get a facial. Sarah’s arms thrashed wildly, and she raised her hips before letting forth a warm torrent of her cum juice squirting out from deep within her.

Poor Marlon was absolutely drenched, and being soaked by Sarah seemed to fill him with a lust that bordered on rage. He grabbed her ankles, spread her legs obscenely wide, and plunged his oversized penis balls deep into her teenage vagina making her scream out in astonishment and delight.

I was reduced to the role of spectator as this magnificent Black bull ravaged my sweet baby girl. His strokes were like a pile driver, and it was clearly apparent that they were both going to reach the pinnacle of ecstasy together, such was the cacophony of their screams and moans.

From behind, I had the perfect view of Marlon’s superb glutes tensing and flexing and his perineum swelling and pumping as he blasted out another huge load. This time, every drop of his essence was injected directly into Sarah’s cervix, and I couldn’t help thinking that her fertile eggs were certain to be overrun by his virile sperm.

When he was completely empty, he withdrew with a liquid ‘plop’ sound, and it was my turn to taste Sarah’s nectar, mixed this time with a pint of his thick and chewy semen. My ass was high in the air, and after no more than a moment's recovery, I felt Marlon move behind me, and his tongue lick up and down my smooth crack, soon finding my tender virgin boihole and pushing inside to open me up.

This was the first time I’d be rimmed, and I was astonished by the sensual pleasure and intimacy of Marlon making love to my bottom with his mouth. I felt my hole dilating and a deep ache inside me that needed to be filled.

Momentarily coming up for air from my wife’s creamy cunt, I called out to Marlon in a voice I hardly recognised, “Fuck me, my king! Fuck me hard and breed me!”

“Paul, you wanton slut,” my beloved squealed in delight, “I can’t believe you’re begging to be fucked like a bitch,” and she pulled my face back into her soaking snatch, where I found her love bottom engorged and erect.

Marlon rose up behind me, taking a firm hold of my phat ass with his huge hands, and I felt the tip of his rock-hard penis against my wet and open hole. I clenched and then relaxed my ring, a come-hither anal wink. He needed no further encouragement, slowly but firmly pushing his huge bulb against, and then into, my tight pussy.

The searing pain was almost intolerable as his gargantuan girth nearly tore me in two. I raised my head and let out a screech of anguish, but Sarah pulled me back down onto her clitty to silence my howls, and very soon I felt Marlon pushing deep into my cavity and the indescribable joy of his cock rubbing against my G-spot, almost immediately making my first ever anal orgasm sweep through me as he built a rhythm, all 9” of him stretching and filling me.

“Oh fuck, so tight, I’m going to cum.” Marlon was fucking me harder and harder. Another sissygasm erupted deep in my asspussy, and as Sarah bucked and writhed as she came again, he let out a roar of triumph and unloaded his balls into me, another heavy load of Black seed coating my walls and filling my sacred sanctum, my cherry well and truly popped.

We collapsed on the bed, all deeply satisfied and somewhat astonished by the tremendous power of our threeway bisexual romp.

Marlon stretched out on his back, majestic and victorious, his enormous Black penis finally resting spent and soft between his thighs, Sarah and I at his side, each cradled in one of his big, strong arms.

“Paul, tomorrow you’re going shopping for a bigger bed. Marlon’s moving in with us.”
