I walk up the path to Adunbi and Quivina's house, bottle of wine in hand. I'm wearing a little yellow dress that reveals more breast and leg than social norms would allow. This is for my brother's benefit. It's his birthday.

I've lusted after Adunbi for ages, but he's married to Quivina, and she's one of my good friends. So I would never make a move on him. But I know that he likes it when I flirt or tease him, and it excites me to do it. It's only a bit of fun.

Quivina answers the door and gives me a welcoming hug. Something's not right—she's not dressed for a party. Instead, she's wearing a short silk robe. It doesn't feel like there's anything underneath.

"Hi, Quivina. Nice robe. Am I early?" I ask my sister-in-law. "Or late?"

"Don't worry, Osa, you're right on time."

I follow her in and look around. "Where is everybody?"

"No one else is coming, " says Quivina, with a sinister glint in her eye.

"Uh, okaaaayyy..."

Quivina relieves me of the bottle of wine. "Look, Osa, I know you're interested for your brother."

Oh, shit. Something heavy is about to go down. "Quivina, I would make a move..." I stammer.

"Don't deny it. I've seen the way you act with them."

I drop to my knees, clasp my hands, and beseech her. "Quivina, I may be a little flirty sometimes, but believe me when I tok say I would never make a play on Adunbi. he's all yours, and that's that!"

Quivina smiles. "Chillax, Osa, I trust you. But you like him?"

"He's nice to look at, " I concede.

"I think that too, " laughs Quivina. "Adunbi is in the bedroom. Go say hello."

Confused, I enter the bedroom. It takes me a couple of seconds to process what I see.

Adunbi is handcuffed, spread-eagled on the bed. He's naked. His cock is half erect. And from his shocked reaction, he is absolutely, definitely not expecting me!

"Quivina, wetin di hell!" he shouts in panic. He reflexively tries to cover himself, snapping the chains of the furry handcuffs taut.

"Whoops, my apologies, Adunbi!" I gasp and turn to flee the room. But Quivina is blocking my escape.

"No be so fast, Osa, " grins Quivina. "I'm sure you'd like a closer look?"

I turn back to look at Adunbi. He's twisting against his bonds in a futile attempt to hide his nakedness from my gaze. I've seen him shirtless before, but never fully naked. His vulnerable position leaves nothing to the imagination.

I stare at his dark brown cock and bite my lip. It's an enormous size. He's gone to the effort of trimming his pubic hair. His balls are nice too. I imagine them cupped in my hand.

"Okay, Quivina, what's going on?" I ask warily, while still staring at Adunbi's balls.

"It's his birthday, Osa. I think your fine. You're a nice surprise."

Adunbi looks from me to Quivina and back to Quivina again. "Jesus Christ, Quivina, I don't think..." he finally whispers, ceasing his struggles. I wonder what's going through his mind. Actually, I wonder what's going through my own mind.

Why would Quivina do this to him? And why do it with me?

As if to answer my unspoken question, Quivina whispers, "Adunbi likes you too, Osa. Watch this!"

She sits next to Adunbi on the bed and starts stroking his hair. "Look, Adunbi, honey, it's your fantasy girl, Osa. You like Osa, don't you? You'd like to see her naked, wouldn't you?"

Adunbi's breathing increases. The poor boy is looking rather stressed.

"You'd like to see some tits, wouldn't you, Adunbi? Grab your sister's perky tits and suck on top of them nipples?"

Adunbi's cock twitches and starts to grow. Before my wide eyes, it lengthens and hardens with Quivina's dirty talk.

"You'd like to fuck her, wouldn't you, Adunbi? Take little Osa over there and fuck her brains out?"

Adunbi's cock springs to a full 25.4 cm (10 in) erection, the glans bulging and dark purple. A little dribble of pre-cum appears at the tip. Shocked, I cover my mouth with my hand. He turns his head away from me.

"Well, Osa, don't just stand there! Say sontin!" begs Quivina. I pick up on a small element of doubt in her voice. She's been very confident up to now, but she's obviously concerned that she might have misread both me and her, and the plan could end in disaster.

"Nice..." I finally say. "Nice cock, broda."

He turns to look at me but can't hold eye contact. "Ummm... thanks?" he offers.

Quivina gets up off the bed and comes over to you. "So Osa, he's all yours if you want. The one rule is you not untie him. If he's helpless, he's not cheating on me - he's just a victim of circumstance!"

I think there might be a flaw in Quivina's reasoning, but I am so flustered and excited that I can't think what it is.

There's an excruciating pause while they wait for my response. I lick my lips. My mouth has gone a little dry, and my stomach is full of butterflies.

"What's up, brother? It looks like I'm your birthday present, " I giggle coquettishly. "Do you want your wife to unwrap me?"

"God, yes!" he replies enthusiastically.

I pull my hair aside so that Quivina can unzip the back of my dress. She eases me out of it, and it falls to the floor, leaving me in just heels. I never wear a bra or panties.

I feel a brief moment of self-conscious, but the excited look on Adunbi's face gives me all the encouragement I need. I twirl for him. Then, with my back to him, I look over my shoulder, hands on my ass. "Like what you seeing, broda?"

"You're fine, well, well," he replies. Then, as a quick afterthought, he adds, "Like Quivina!"

"Nice save," says Quivina. "Make a sight of how my breasts compare!"

 I squeeze my bare tits together and give Adunbi a sultry look. "You like the sight my tits, brother?"

"Fuck yeah!"

I drop my hands to my hips and wiggle my bare, petite breasts at him. He inhales sharply, and his cock twitches in appreciation.

To my surprise, Quivina comes behind me, does the reach-around, and starts fondling my tits. "They feel just as nice as they look, husband." she teases.

I'm not sure how I feel about my friend copping a feel, so I decide to pretend it isn't happening. Unfortunately, this leaves me unprepared for when she squats behind me and giving my bum a little kiss.

"Quivina!" I admonish her as she stands up again. She looks back at me with a cheeky, fake innocent expression. Then I remember Adunbi. Totally naked in front of him, I spin around and strike a sexy pose with one hand on a jutting hip.

I can hear Adunbi's rapid breathing across the room. His eyes are wide, trying to drink in as much of my nakedness as they can. His cock is so engorged it looks painful.

On impulse I kiss Quivina deeply. She tastes sweet too. When my lips pull apart, her breathless excitement is evident.

"What's up, Quivina? Want to put on a show!" I suggest.

While Adunbi watches in helpless amazement, I undo Quivina's robe, and it drops to the floor, leaving her just as naked as me. I embrace her again, our soft bodies pressed together. When I squeeze her ass, I'm rewarded by a soft moan and her tongue down my throat.

Quivina kisses her way down my neck towards my breasts. Cupping them in her hands, she sucks a dark nipple into her wet mouth and runs her tongue around it. I sigh and smile at Adunbi, who is transfixed by the sight of his wife pleasuring the object of his forbidden lust.

I slide my fingers through Quivina's hair and push her head further down. She rains kisses down my tummy and around my crotch. I part my legs and push her head between them, expecting her to resist. She doesn't.

Quivina's tongue finds its way into my slit and starts working sheer magic with my clitoris. Her hands massage my bum cheeks, pulling me tight against her face. It's awesome. I suspect she might have done this before.

Adunbi twists and turns in his bonds, desperate to join the action. A dribble of pre-cum emerges from his cock and runs down his throbbing shaft. My pussy is dripping too, but it doesn't seem to bother Quivina.

"Oh, Quivina, that's fantastic, " I moan. "Dat's it, right, there! Don't fucking stop!"

Quivina's tongue action becomes more frantic, and my orgasm starts to build. Without slowing her assault on my clit, she shoves a thumb up my cunny. I see stars as a tsunami of pleasure hits me, and my knees buckle. Quivina bears most of my weight with my twitching pussy pressed firmly against her mouth.

When it is over, I collapse on the bed next to Adunbi. Quivina takes the other side.

"Do you like that, Osa?" asks Quivina sweetly, her face shiny with my juices.

"I get no words..." I pant.

"Don't forget about me?" whimpers Adunbi, desperate for release.

"Climb aboard, Osa," suggests Quivina. Still recovering from my orgasm but ready for more, I straddle Adunbi eagerly.

Quivina grabs my brother's cock and rubs the head against my pussy, masturbating me with her husband's knob. "Shall us dip it in her, Adunbi?" she teases.

Adunbi seems to have lost the capacity for speech, but he nods frantically.

"Osa, it to be like that, your brother wants to fuck you with this massive cock in him. Is that okay with you?" Quivina asks.

"Uh huh, " I affirm, biting my lower lip and meeting Adunbi's gaze. I feel a desperate need to be at one with him, our bodies pulling together like neodymium magnets.

Quivina guides Adunbi's knob between my pussy lips, and I sink myself down on it slowly. He stretches me deeply, and I sigh happily.

"How do she feel, Adunbi?" asks Quivina.

"She bam," he replies. "Osa, you're bam!"

"You're not so bad yourself, stud!" I reply, easing my cunt up and down his shaft. I build up to a rapid pace while Adunbi flexes his hips, trying to get deeper inside me.

Quivina gets down between his legs and starts licking at his balls. I feel her soft hair brushing against my ass. Then she works her way around and starts licking at my clit while I grind down on Adunbi. I grab her head and hold her there while another orgasm hits me, and my pussy clamps on Adunbi's cock with a series of micro-contractions.

"Come in me, brother; shoot your sperms deep in me!" I cry.

"Yes, husband, " Quivina yelled, "make your baby in your sister's womb!"

Adunbi's eyes roll back, and he rams his cock into my spasming cunny, pushing my cervix deep into my uterus, before flooding me with gooey white man juice. I bounce hard on him while he shoots, leaking sperm from my pussy and making loud, wet splatting sounds with my butt against his sweaty thighs. Then I collapse on him, our sweat acting like a glue that makes us stick together, my cunny and his cock throbbing in unison as he empties his last few drops of cum into my womb.

Finally, Quivina pulls Adunbi's deflating cock from my pussy and engulfs his soggy manhood with her mouth, sucking him clean. I ease myself off him and cuddle alongside, cum oozing out from my satisfied cunny.

Later, when Adunbi is freed, we tie Quivina to the bed and take turns pleasuring her. She deserves it for being such a good friend and wife!
