Do You Like Big Sis' Big Tits?

Yuu is a diligent student, but he just can’t focus on his studies with Sakurako, the girl from his neighbourhood, constantly coming over to hang out. On top of being a nuisance, she’s very well endowed and just the sight of her provides ample distraction.

One day, after falling asleep reading a manga on his bed, Sakurako wakes up to Yuu stroking himself to her sleeping figure. Even while keeping the pretense of sleeping the sight and smell makes her get extremely horny. With that, the whole situation gets very dangerous~
