Story seems to go into stupid territory, but then dude is insatiable borderline rapist that will fuck anything that moves, and probably anything that doesn't move either - aka if someone put a full sized sex doll in his bed he would cover it in jizz in single day from head down to feet.
Kinda funny how they kinda depicted him as being good in bed - giving girls pleasure - while he fucks them like they are some kinda toys - no fluff, no wholesomeness, no "romanticism" if you will. Its like the only reason they feel pleasure is just that he fucks them so much they get sensitive out of being exhausted or something, and as he fucks like a duracel advertisement bunny - horny for that pussy so much that if he could he probably wouldn't put it out for whole day and just dry hump till exhaustion, he manages to "reach that goal on them girls".
Heck him being kinda quick shot and thus not humping long enough for that "sensitivity out of exhaustion" in the girls to show up for them to feel good was kinda a main point - when the first girl actually got angry that he just fucks her in short burts whenever he feels like it, and thus not long enough for her to finally feel good.
At least it spewed live action porno with a small breasted actress - so a nice change where for once adaptation made the chest smaller - petanko enjoyer like me approves
