Your step-Mom is wearing a black bra and skin tight jeans. She sits on your bed, telling you how happy she is that your step-Dad is gone for a whole week! She tells you that she has seen you staring at your ass, standing up, giving you a complete view of her fantastic ass. She teases you more by peeling off her pants, revealing her black g-string. After some teasing, saying that you want to be inside her, she comes close to your face and swallows you whole. step-Mommy's tummy is big and full; she laughs at your ignorance while rubbing her extended stomach. While mocking your struggles, she tells you that you should jerk your cock and cum; this way, you really can cum inside step-Mommy, what you wanted to do in the first place. After all, it will be days before your step-father comes home, and you'll be long gone. When he does come home, step-Dad is going to grab your fat ass, not knowing that you are the step-son why it got so big after he left!
