CW: Incest, sph, chastity.

My cousin (32M) and I (31M) grew up playing strip games and truth or dare that lead to more as we got older (been told i cant post most of those stories without them getting pulled down). Not that long ago we went on a weekend trip for his brother bachelor party and shared a room for the weekend. Side note that comes up later, my partner and I have gotten into chastity, having me buy a silicone cage that i can wear for long periods of time and my partner loved the idea of sending me to the bachelor party with my little 3.5” dick locked up, especially given that he knew my past with the cousin I was sharing a room with. The main night of the bachelor party we go out to a club and we are big group of 26 y/o finance bros and former college frat guys. Not the usual type I hang out with, but the testosterone is heavy in this group and they are not light on money either. They decide to get bottle service for the night and the club keeps bring out shots. We are absolutely trashed leaving that club. I’m desperately tired also. As the group stumbles to the next bar/club (which i later learned was a strip club), we walk past our hotel and my cousin who i’m sharing a room with says he needs to pee, the group is about to stop to wait for him, I say I also have to use the bathroom and will go with him. The group stumbles on and just the two of us head back to the rooms. I’m sitting on the bed seriously thinking about calling it a night. When my cousin comes out of the bathroom with his pants down and a small bulge in his boxer-briefs. Neither of us is hung and my partner loves to remind me that he is bigger than both of us put together. My cousin walks up to me, takes my hand and puts it on his hard little bulge. Im surprised at first because it’s been years since we have done anything and then I remember i’m locked up and cant really do anything, but we start making out as i rub his bulge. My cousin is in more dominant mood then I remember and makes me pull his underwear down, and his little hard on springs forward. He shoves my face in it and makes me suck him for a bit. Face fucking me pretty ruffly from how drunk he is. He pulls me off his cock and tells me he wants to blow me now and starts to undo my pants. I admit he can’t and when he asks why, I just let him finish taking my pants off. He sees the cage and tells me to take it off. I tell him that I cant because my partner put it on me. He then surprises me more, we start making out again and he starts pulling on the cage, hard and hard with each pull. I’m crazy horny at that point when he gives it a really hard pull and my little package pops free of the cage. It never even occurred to me that was possible before that. As soon as its off my cousin starts going down on my already fully hard dick. He blows me for a while, easily deep throating me, even though he claims to be straight, before pulling off me and telling me to fuck him. He spits on my dick and then tells me to stick it in him. We are both pretty drunk, so as hot as this is I’m having a hard time staying in him. He is jerking his little dick as i fuck him and he begs for me to go harder and deeper, i’m embarrassed to admit i’m balls deep at that point. Not long after that he pulls off me, lays back on the bed and tells me to cum on him as he jerks off. It doesn’t take either of us long before we are shooting long jets of cum all over his hairy chest. He cleans up and we both pass out shortly after. The next morning he tells me he doesn’t remember leaving the club and coming back to the room, but the way he says it makes me think thats his way of not commenting on a his not so straight end to the night. When i get home that night I tell my partner the whole story and i get punished for removing the cage, but thats a story for a different sub.
