Help please!

I've been looking for a yaoi manga I read some time ago and I can't remember the name. It was with one-shots. The seme and the uke were best friends and had girlfriends but started cheating on them with eachother. And they spent their summer or something together and were really passionate and they even made a piercing on each other. The uke had his tongue pierced and the seme had his **** pierced lol. There was some sort of misunderstanding and they didn't meet again and after a couple of years they meet on the street and the uke turns to the seme showing him the piercing.
