Pick Up
...Yeah... Ok... Story: A guy gets drunk, he meets someone in the bar. This guy takes him somewhere, ties him up and plays with him. The drunk head then searches for him. One time they meet again - the drunkhead had a "boyfriend" with him and the other guy from the bar got seriously pissed cause his "dog" wasn't loyal to him so he fucked him again.
Docchi ni Suru?
1 story: 1 uke, 2 semes, always a threesome even though the semes hate each other they still love the uke. They "all" are childhood friends. 2 story: A guy works at a company. He has a kohai there. He has a crush on him. One day they drank some sake and ended up in a hotel. They has sex - the senpai being the uke (unwillingly at first).
Sekinin Torasete!
2 friends from college. They are still in college. Anyway one time they went out drinking and 1 of the got drunk. the drunk guy went to a love hotel to sleep but ended up having sex with the other one. The other one have had a crush on him for all this time and he's a tsundere. In the morning the drunk guy has a hangover and doesn't remember shit which kinda pissed off the tsundere (but didn't really say anything about his current feelings, he just told him that he got drunk, they ended up having sex and that he had crush on him). Afterwards the drunk head actually realise that he likes the tsundere. They ended up as a couple.
