Me and my stepbrother have to share a room with one bed because parents are stingy people. We are getting ready for family dinner, I just got out of the shower in one towel, not much time left until dinner. stepbrother is not going to shower, I started cursing at him and we ended up fighting as I asked him to go take a shower. Everything is fun until stepbrother's cock ends up inside me because his cock fell out of his boxers and slid into my tight wet pussy. It shocked us both so much and we didn't move for a couple seconds in total shock. stepbrother, I complain about it but can't help but like it, denying it the whole time. Me and my stepsibling fuck for a while, frustrated at how nice it felt. I cum on my stepbrother's cock long resisting it, Not taking birth control, I wasn't happy but couldn't deny how good it felt. We were late for the event and I had his cum dripping down my leg all evening
