In a love hotel room... a man who has a lot of free time on his hands due to recent circumstances is waiting for a call girl, and the one who arrives is... The first is a female college student who calls me "big brother" and is my childhood friend Riho... The second is my childhood friend Himari, who is six years younger than me and was my student when I was a tutor... The third is Hina, a childhood Hina from when I still lived in the countryside... She suddenly starts playing with my private parts and I explode, losing all sense of reason and modesty as I continue to shake my hips in a frenzy!
