You're having a hot and sweaty work out session with mommy. She squats and stretches in front of you, and you can't help but admire her hot body, perky tits and big ass. The more you look, the more horny you get and your cock gets hard. After the cool down, mommy tells you to stand, but you can't other wise she will see your big dick print. You get shy and embarrassed, and eventually tell mommy you're hard and its all her fault, her tiny sports bra and yoga pants have made you so horny and now you need relieving. Mommy is shocked, but she likes the thought of her son being aroused by her, and you tell her how pretty she is, her fat lips and perky tits, and she strips for you whilst telling you to stroke over mummy's hot tight body. Mommy can't take it anymore, she wants to help too, and strokes you cock, sucking and licking until you drain your balls all over her face.
