Ôru naito rongu R (2002)

This is the fourth in the All Night Long series, though with no suns available, it's little unclear what exactly is going on.But it appears that Yuuki , a young, endearing Japanese man is experimenting with body modification. His initial trials-runs are one fish and rats.Pleased with the results, he moves to women.Yuuki also appears to be programming himself a virtual fantasy world into which he often slips , sometimes unintentionally .His first (known) victim is Reika , a pornstar with her own website where she offers typical fanclub stuff.Through one such video , Yuuki is able to figure out her address. He pays her a visit and wins her warm heart, all for himself.The second girl that Yuuki sets eye seems to be a call girl he intends to keep a little longer for himself.Of course while modifying her to his taste - when a couple of boobs are not aesthetically positioned , you add a third for triangular symmetry.And an extra ear nearby, to hear their appreciative applause.There's also a bully who constantly threatens Yuuki for some reason and he too will soon come into the mix.
