Stepmom Offers Her Massive Tits for a Birthday Fuck

Today's my stepson's birthday, and it should be a special day, but sometimes I think he'll be a virgin forever, and I worry. He's older now, and he should know what a pussy tastes and feels like, so I have the perfect deal so we can both get what we want. I've been trying to get pregnant, but my husband isn't doing it for me, so if my stepson can give me his seed, I'll let him fuck me. All I have to do is give him the best gift he can get: my massive tits. I'll put a nice bow on them and let him unwrap them. He can squeeze, lick, or fuck them. Anything he wants. I'll take care of his dick, sucking it dry until he's hard enough to shove it inside my pussy. Pounding me will feel so good he won't be able to pull out before cumming. I'll get pregnant, and he'll get to empty his balls inside a woman for the first time. We both win.
