Musclemommy is at it again playing perverted games with her son. Musclemommy has her son, Kevin spot her for a set of 185# incline presses. She has the idea that she needs some more testosterone to get even stronger so she sucks on her Kevin'cock. Each time she sucks she gets stronger....she does 50# dumbell curls easily and pumps up repeatedly as the takes his cock in her mouth between sets. She requests that Kevin stroke off for her while he watches her pump and flex. He obliges, stroking himself to a big cum mess as he watches and listens to musclemommy's encouragement.
