Stepdad's fears of impregnating me lead to safe sex during oral sex

My stepdad has this weird fetish that I'm going to get pregnant. He's always stressing about it, even when we're just chilling. But, damn, he's got a big black cock that I love to suck on. One day, we're just hanging out in the living room and he's trying to avoid me. I tease him a bit and he gives in, letting me go to town on his cock. I'm a fan of good cock, and his is no exception. We move to the bedroom and he's all giddy about using protection. He's got this weird thing about precautions, but whatever. He's got a nice ass and I'm all about that. I hope my mom doesn't walk in, but I'm enjoying the moment. I'm a horny babe and I'm not afraid to show it. I hope you enjoy watching as much as I enjoy performing.
