Yeah, though he _did_ give out on her after cumming, which is her complaint, so either it's kind of weird that he can then do 62+ push-ups (with her on his back no less), or he needs to build up different muscles than what he uses with push-ups. But it was done for comedic effect, and reality and hentai often don't get along...
Great ending...Heh, well, if she can't stop being a slut, what other method do you have other than to satisfy her enough where she'll only stick with you?
She stops seeing other guys and becomes all yours...And while I do feel bad for the guy since he got his dreams of her crushed, at least he still sort of got her in the end?
In a sense i feel bad for the vice-president. He got his dreams of the president crushed, abused by her and is now in her hand. (Though he pretty much got her addicted to his dick)
