My boyfriend, let's call him Sam, lives at residents, with a roommate. Usually we have no clue if his roomie is there or not- we can hear the door, but we don't know if he's coming in or out. Anyway, we were sitting in his room, I was in my bra and panties, and he was in his boxers (his room is usually very hot), we were watching TV when Sam reached over and started playing with my tits, first over my bra, then he snaked his hand under my bra. Eventually my bra came off. I could see his boxers start to get tented. We made out for a bit, which made him completely hard.
I reached over and started jacking off his cock through his boxers, as he reached over and started to rub my pussy. Soon after, the panties and boxers came off. I jacked off his cock, as he fingered my pussy. Sam guided me to making him cum faster, it wasn't long till his cum was all over my hand and his chest. Not long after that, I came on his hand. I'm not noisy when I cum, and I'm glad, never knowing if his roommate is there or not. Though I'm sure he knows what we are doing anyway.
Every time I got over there, we get each other off, and more.
