Visual Aid

Tristan is struggling with his math studies, trying to understand the conversion system. He really wants to go college but doesn’t know how to convert feet to inches, so his stepbro Jack helps him out. Noticing how distracted Tristan is, Jack decides to take out his cock to use it as a visual aid. Tristan starts to get the hang of it and asks his stepbrother if he can touch it. Jack doesn’t mind as long as Tristan puts it into his mouth and fills it up with saliva. Horned up by his little stepbro’s cock–sucking skills, Jack eats Tristan’s asshole and proceeds to stuff it with his meat to see how many inches he can take up his hole. Jack plows Tristan’s cum hole and makes him bounce on his dick, helping the twink focus. Finally, as he jerks off on his knees, Tristan can now explain the conversion system!
