Thrill

*Gets excited over the glasses tag* Wait....
By the way: The best part was him tacking the phone and telling his sister to shut up because she disturbed the banging. I laughed like a madman...

...Yeah, I kind of really like the art. For this release, I especially like the eyes.
It's like...You can visibly see a change in her eyes the moment she stripped naked and looked towards him(and by extension, us reading it).
Great ending though. Heh, I guess he lost more than just his game...But I'm sure it was worth it.
Hell, he'll probably be back and ready for a rematch the next day, and I'm sure she'd welcome it.
That game/game developer was quite the wingman, though! And by extension, his sister also for bringing her friend over.

Sticking it in crazy never felt so good.

At least he should be glad she didn't force him to dress like a girl and get pegged.

OH Man Oh Man

Missing shota tag?

Tutoring in hentai always just consists of "using the formula here". Yeah, super helpful.

Little Brother (a.k.a. Lucky Bastard) was taken to the very edge of "snu-snu", but managed to stay alive, and from all indications, sister's friend seemed to enjoy it also.

TOTALLY WORTH IT!!!!!

EDIT: guessing she's older than him, so I call Sexy Onee-san for this one.

This is exactly what I love to see from Takemasa Takeshi-sensei. So good!
