When I quizzed her about her fantasies, my girlfriend had often mentioned wanting to try double penetration, and after I had suggested we should go through with it we got into some couples dating apps and found a guy we both liked the looks of - gym fit, athletic build with a big gorgeous cock that puts my to shame. Uncut, black, thick girth and perfect with a slight curve to it. Me and my gf touched each other while looking at his pics and chatted with him about wanting a threesome, he said was up for it as he is bi. We shared pictures of her ass and pussy, her body and mine. She had also sent a picture of me in my cock cage and her in lingerie which had embarrassed me, but also excited me a lot to know this man with such a powerful cock was seeing me looking so submissive and pathetic. He loved her juicy booty - and complimented my cock and arse too.
We had agreed a day and time when he would come over for our threesome, and we're going to try Double penetration. One in her pussy, one in her arse. The morning arrives. As soon as I wake up she takes out a small chastity cage, locks me up and tell me I'll be locked until he arrives - to stop me jerking off and tells me to be a good boy. Always wanting to please her, I obey and wait excitedly. She puts the key on a silver neckchain and puts it on. She likes to be in control and wears it visibly; as a reminder that I am to obey her.
My cock strains against the tight cage every time I think about what will happen that night. When he arrives, she takes him by the hand and leads his upstairs. He grabs at her arse in front of him, her cheeks shifting in his large palm with each step. My heart races with desire and anticipation as I follow them up.
With me still caged, she sits on the bed, so her face is at his crotch. She pulls down his trousers and we see his massive bulge. My cock twitches in response. She pulls down the waistband of his boxers, which tighten onto his cock, showing a clear imprint of his junk before it pops out in all its glory. His big black cock is perfectly shaped with a huge head and foreskin intact. A beautiful chocolate colour and what must be 9 inches in length and 6 inches in girth. It has a thick black vein up the back, making it even thicker. She takes in an eye full, with such lust and desire - then proceeds to take my shorts off. My little cock and ball package tightly wrapped in chastity looks tiny in comparison. I flush with embarrassment as she explains to him that she is my keyholder and my cock is under her command. Still with my cage key around her neck she says "Time to get you unlocked". She reaches for the necklace and lifts it over her head; but then she pauses... "but, you've been such a good boy so far and, you do need to obey me... so I'm gonna have some fun." Her gaze shifts back to his huge dick, and she puts the necklace around his thick semi hard cock and shaved balls. My cage key is now wrapped around his BBC.
She kissed and licks it, making him get harder and the head even larger. "If you can take him ALL the way and lick the key with your tongue... I'll let you out and we can try the DP". Bewildered, I look at his cock, then at her, unsure if she means what she said. She interrupts my thoughts with "Shove that big fat cock in your mouth!" and she pushes my face right into his crotch.
