The Last Lover
Itoshi no XL Saizu
Well, shit. Hot. College boy Yamamoto joins the sake club thinking it could be a way to get a girlfriend and lose his virginity, but the club is all guys and he gets drunk and taken home by another club member, Kobayashi, who says he's a virgin too. Kobayashi says that he's a virgin because his huge cock scares girls away. Yamamoto, maybe because he's drunk, seems to have no issue getting handsy, and more, with Kobayashi's penis lol

30 Sai Kara no Coming Out
Not a particularly deep plot but nice anyway, with good art. Mitsuru is a 30 salaryman from the country who moves to the city to put himself out there romantically/sexually. He meets Haruka through an app and they have a one nice stand only to realize they're coworkers and Haruka decides that one time wasn't enough.
