私のBFのstepBrotherを吹くので、彼はタトルしません

My boyfriend's parents are out of town and I spent the night having crazy sex with him all night. In the morning I went downstairs to get some water and ran into his little stepbrother sitting on the couch playing video games. He didn't realize that I was still there. Instead of being cool about it, he threatened to tell his parents. I didn't want him to do that and ruin what I had with his stepbrother, so I made him a deal. I'll suck his cock and show him what it's like to have an experienced cock sucker drain his balls, and he doesn't say a word of this to anyone. I let him enjoy getting his cock sucked, but I didn't want a mess that I had to deal with. Just at the moment that he came, I let him blow his load on his stomach denying him the best part of his orgasm. I needed to leave him with a little something to be hopeful for. I really don't mind having to suck off my boyfriend's stepbrother to keep him quiet. He's actually really cute and has a nice cock.
