Sweetie, I insist on showing your new girlfriend how i take care of all your needs especially that big one

*POV via stepson with stepson's girlfriend just off to the side.* I'm so glad you finally introduced me to your girlfriend, sweetie. She's a beautiful girl. Did you tell her about...um...YOU KNOW. I'm guessing "no" which is why you hadn't introduced us sooner. She needs to know. Fine I'll tell her. *So since my stepson doesn't talk to me about his sex life I'll ask you. Have you been intimate together? No? Not even a handjob? Blowjob? Wow you ARE a good girl. I'll make sure my stepson keeps you around. I guess you don't know of the issue he's had with past girlfriends. To be shy, he's VERY well-endowed. His cock is HUGE. Biggest I'VE SEEN. His needs weren't fulfilled, so I did what any naughty stepmom would do, I let him fuck me. I satisfy my boy ANY TIME he wants.* Sweetie, your gf hasn't run out yet. She might be up for this challenge. My turn first while she watches. You've been blessed with a humungous cock & I'm blessed with a pussy that can take it....
