You're my son and you walk in on me while I’m finishing my workout and about to stretch. I ask if you can help me stretch even deeper and I eventually feel your erection against... me! You get shy about it but I say it’s okay and that I like it. I ask if you ever jerk off thinking about me and you admit yes! That turns me on and suggest we have some fun. I ask what your favorite part of me turns you on the most and you say my ass. So, I decide to rub against you giving an assjob until you cum between my cheeks.
