When you jerk off to Facebook pics of your friends and people you know. It always happens when your hot friend posts those stupid nudist camp photos and you can't help yourself.
My friend posted a pic of her in a bikini and I immediately started wanking in my math class.
I saw my crush at the nudist camp and I had to hide my phone under my blanket.
He posted a group photo of us at the beach and I got a hard-on during lunch.
