Sweetie, I told my best friend the secret to having great sex, you, my boy

You're up in your bedroom but stepmom & her friend sit on the couch chatting when the conversation turns to sex. How often does stepmom get laid? Every night?! What's her secret? She confesses to having sex with you. It's the best sex ever. She talks about how big your cock is, hard it gets & how quickly you recover. You can go all night. Stepmom asks her friend if she'd like to watch. Of course, she says yes! Stepmom calls you downstairs. She says her friend (who you think is a total MILF) watches to watch you and her fuck. She encourages you to take out your cock and fuck her really well. Stepmom notices her best friend squirming and tells her she can get herself off too while she watches. You fuck your stepmom, and all the while she praises you about how incredible your cock feels...
