Highly acclaimed project second round! What happens when two couples of college students on a hot spring trip, each with a well-endowed male and a big-butted female, are made to share an open-air bath? Though they blush and falter from the new experience… young men and women meeting for the first time gradually heat up with an intense big butt washing mission! Forgetting about their respective boyfriends and girlfriends, they engage in dense, consecutive double cheating sex with their well-endowed parts pressed together! Enjoy every moment from 'Nice to meet you' to H butt fusion, covered only by a towel!
