Getting it On With Your Gaming Buddy at the Hot Spring

Sakamoto, an ordinary college student, becomes friends with a beautiful girl he met at his part-time job, Mari Himeya, through a competitive game, and on holidays they play against each other in his room. One day, however, Mari wore mini-skirted knee-socks. Sakamoto, a big fan of mini-skirts and knee-socks, couldn't help but notice Mari's lower half. As the game heats up, Mari lets her guard down and shows her panties all over the place. Can Sakamoto really hold back his sexual desire for his friend? Of course not! *Note: As a setting, it is treated as a prequel of Isekai AV Satsueitai. The heroine's name may be different, but if you look closely at chapter 4 of Isekai AV Satsueitai, her real name Mari appears at the bottom of her Career Survey.*

*What if... Sakamoto hadn't step into the scene where Mari was taking a mixed bath with a group of strangers?* Mari Himeya goes on a lovey-dovey hot spring trip alone with her game-loving boyfriend. However, her boyfriend becomes obsessed with the retro games at the hotel and leaves Mari alone. Unknowingly, she is picked up by two burly college rugby players... Can these rugby players, with their voracious sexual appetites, resist the temptation to show each other off? Can Mari keep her fidelity to her boyfriend? *Note: Follows the opposite development from the lovemaking version.*
