Young cock is easy to train plus very satisfying in size. She is loose & had him pound her hard & deep, as an experienced man would do. Hopefully he will not assume that tight pussy takes it the same way, cuz not so. He could fuck other unexperienced females & wll get turned on by tightness, thereby not stopping until he cums. This would b a rape & female could b traumatized, but he will continue to do it rough, as the loose one who trained him, was his first.
