When Eric Charming reveals to his older step-brother that he’s being picked on at school, he asks for some help to get him prepared to take them on. It’s noticing just how fit Eric’s step-bro is that gives him the incentive to make this request, although perhaps he had something else in mind when he asked for assistance. Jack kindly offers to take on the bully’s himself, but Eric prefers to build muscle so he can be more independent. It seems that watching Eric performing pushups is what pushes the guys into a more sexual direction, especially when Jack sees Eric’s irresistible butt – he wants to slide his raw cock in between those beautiful cheeks and fuck him! You can pretty much tell that things escalate from this point, with the guys taking a more active role in their muscle building exercise!
