Senpai no Mizugi
Story 1 (ch.1-5 + 11): seme (kouhai) x uke (senpai) both are university students, swimming club Story 2 (ch.6-10): about best friends, seme masturbrates with uke's swimsuit - Swimsuit fetish in both stories
Unfather
Uke (young, college student, has sex for money) didn't end up together with anyone, he didn't loved anyone, he had two possessive semes (a younger and an older one) and the young seme killed ukes mum even though the young seme wanted to kill the old seme. A story with zero romantic love.
Kyouai Shinri Paradox
Big brother (uke, professor) tries to hid his love for his younger brother (law student, does judo, it seems he has feeling for his big bro), but another guy (seme, psychology student) founds out about uke's feelings for his brother and blackmails him. Uke has to listen to everything he says.
