Spanish The world of hentai manga often explores daring and provocative themes, and this Ben 10 spin-off is no exception. The story begins with Gwen, Ben's cousin, adopting a provocative posture. She spreads her legs in front of her cousin and makes disparaging remarks about the size of his penis, saying that Ben wouldn't know how to use it. Under the mixture of emotions generated by Gwen's provocations, Ben succumbs to his impulses. In the heat of the moment, he gets carried away by his excitement and decides to prove Gwen wrong . He advances on her and the scene that develops is one of an intense sexual encounter. Ben fucks Gwen's pussy vigorously, all her insecurities momentarily eclipsed by unbridled passion. At the climax of their intense interaction, Ben decides not to stop there. Using his Omnitrix, he transforms into an alien with a large, thick penis. The change of form is not only physical but also impacts Gwen psychologically. She is overcome with fear and unexpected surprise at Ben's new form, resulting in an electrifying and surprising ending to this hentai manga.
