I'm looking for these stories on behalf of a friend and id be really grateful if someone knows them because I haven't had any luck so far in finding them.
Description:
It has multiple stories. One chapter involves two friends and they're watch AV videos together. They get curious then mimic them.
The chapter after that one involves uke going around a fair with a vibrator in him and a dude finds out about the vibrator.

Is it Komatta Yatsu chapters 3-5?

I read it and it sounds exactly the same, but I'll confirm it with my friend just to be sure.
Thank you so much for taking out the time to find this one
(๑•̀ㅂ•́)و✧Have a blessed day 🙂

She confirmed it and it's the right one. Thank you so much.
