First things first: this was fucking hot, and I love the art. However, no matter how much I miss sex - last time would be almost five years ago, 12th October 2010; yeah, my memory's funny like that - I don't think I'd be able to cope with this much nor do I think any normal man or woman would. Not even porn actors.
Again, I just can't help pointing out that even if he did hold out on masturbating for a week, he would've involuntarily ejaculated after three or four days. Yes, yes, hentai logic, but it's one of those things that bothers me more than others when it comes to eromanga.
