I've been noticing some shady behavior from my ma lately, and I'm convinced she's cheating on my stepdad. I decide to confront him about it, but he's not being very forthcoming. I call him out, asking if he's not satisfying my ma in the bedroom. He tries to brush it off, but I'm not buying it. I've seen my boyfriend's impressive cock, and I'm curious to see what my stepdad is working with. When he refuses to show me, I take matters into my own hands, pantsing him when he is distracted! Let's just say my suspicions are confirmed - there's no way he can satisfy my ma with that tiny dick! I try to help him get in the mood, even going so far as to get topless myself, but nothing seems to be working. He tries to tell me it gets bigger, but when I start playing with it, it seems to shrink even more. This explains a lot...
