初恋のお姉さんはオヤジの性欲処理便器でした

"I can't stand to see the girl I've loved since childhood being this nasty!"

Takashi met Karin, the older girl next door when he was a young boy, after several years at a class reunion.
When he sees her unleashing her hot body on the c*ck of a middle aged man... is this really the neighbor he knew so well?!

"I'm sorry I'm this kind of girl! Anhhnn, ahhnn, don't despise me! Aahhhhhh!"

* An amazing collaboration of netorare creator Eri Momono x loving elder sister illustrator Yuuya Igarashi.
