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?”
“De tin be say, Osa, you’re right on top taim.”
I follow her in and look around. “Where is everybody?”
“Send else de come,” says Quivina, with a sinister glint in her eye.
“Uh, okaaaayyy...”
Quivina relieves me of the bottle of wine. “Look, Osa, I sabi you’re interested for ya broda.” Oh, shit. Something heavy is about to go down. “Quivina, I would lai lai...” I stammer. “No deny it. I’ve seen di way you act dey am.”
I drop to my knees, clasp my hands, and beseech her. “Quivina, I sabi I fit be a little flirty sometimes, but abeg believe me wen I tok wey I would lai lai, ever mek a play on top Adunbi. Im’s all yours, and dat’s dat!”
Quivina smiles. “Chillax, Osa, i trust you. But you laik am, shikena?”
“Him’s nice to look for,” I concede.
“I reason dat one too,” laughs Quivina. “Adunbi na for di bedroom. Go tok 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, apologies Adunbi!” I gasp and turn to flee the room. But Quivina is blocking my escape. “No bi so fast, Osa,” grins Quivina. “I’m sure you’d laik 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, wetin’s going on?” I ask warily, while still staring at Adunbi’s balls.
“It’s him birthday, Osa. I think we fit find am a nice surprise”
Adunbi looks from me to Quivina and back to Quivina again. “Jesus Christ, Quivina, I lai lai 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 dis!”
She sits next to Adunbi on the bed and starts stroking his hair. “Look, Adunbi, honey, it’s ya fantasy geh, Osa. You laik Osa, no you? You’d laik to sight am naked, wouldn’t you?”
Adunbi’s breathing increases. The poor boy is looking rather stressed.
“You’d laik to sight am tits, wouldn’t you, Adunbi? Grab ya sista’s perky tits and suck on top am nipples?”
Adunbi’s cock twitches and starts to grow. Before my wide eyes, it lengthens and hardens with Quivina’s dirty talk.
“You’d laik to fuck am, wouldn’t you, Adunbi? Take little Osa ova dia and fuck am brains komot?” Adunbi’s cock springs to full 24.4 cm (9.6 in) erection, the glans bulging and 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.
“Wella, Osa, no juss tanda dia! Tok 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 dick, 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 me. “So Osa, im’s all yours if you wan. Di one rule na you no fit untie am. If him’s helpless, him’s no bi cheating on top me – him’s juss a victim for 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.
“How far broda, it looks laik i’m ya birthday present,” I giggle coquettishly. “Do you wan Quivina to unwrap me?”
“Gods 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 panic, 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. “Laik wetin you sight, bro?”
