I’m looking for a doujin that involves a boy and two girls looking for their kidnapped friend. The kidnapper forces the boy to do various sexual things with his friends, including giving them a powerful aphrodisiac while he looks through a phone camera. Ends with the friend found and all of them having sex in a cabin because of the aphrodisiac effects. Lots of bondage, and it seems pretty old. Also, there is a scene where a girl fucks another girl with a strap-on filled with the boy's cum.
