Kanojo No Gal Na Onee-san Ni Sasowareta Node Shimashita (“My Girlfriend’s Gal-like Onee-san Seduced Me And We Had Sex”) [English], by Moririn-Monson
The early bird gets the dick? No, I’m sorry, I have the original proverb in mind but there’s no way to twist it into making sense with an hentai adaptation.
–Edit: MHM got it!! The horny chick gets the dick
Anyway, we have a couple of youngsters going out for 6 months already, the girl shies away from mere trivialities like a kiss, but fortunately her older sister comes around and gives the boy a world-class first time while little sis is away. Awesome sex with a cute gyaru, the end =)
You may morally object, it’s your entire right, but personally I was all for it. A teenager at peak hormones can’t be made to endure six months of blueballing, it’s beyond human strength
It’s been released by Desudesu, and commissioned by Taco, many thanks!
