1, 4 & 5 are good. Sweet considerate guys. Zero toxicity and the couples are cute.
2 can kiss my ass. "Accidentally", sleeping with a teen is one thing (not a fan but she wasn't that much older than him and she was drunk, he was in the wrong though, if she was so drunk that she blacked out and doesn't remember, then she stank of booze and it would have been obvious) but to pressure him to take a shower photo so you can pass it around to your disgusting "friends" is ALL kinds of F'd up! It would also be considered "distribution of child pornography" because he's under age, you scummy ass characters! As for story 3, I didn't bother because I don't give to shits about your "love" for your cousin (you can keep your gross incest, thanks).
