I was at my friend's house to hang out and get a lesson on his piano. I was feeling so fucking horny, the thought of fucking him on the piano had been running through my mind all day. He's in a relationship so nothing could happen, but I brought my mini vibrator with me in case the opportunity arose to make myself cum. The thought of secretly doing it had me throbbing and soaking wet. He ended up having to step out for a few minutes and I started rubbing my clit. The risk of it made me throb...I was fucking my pussy with my vibrator, my legs spread wide, feet up on the piano keys, dripping all over the bench. I was fucking myself harder, faster, knowing he could walk in any second. And then it happened...just one minute before he got back, I came so fucking hard, barely stifling my moans. God, it felt so fucking amazing. Thinking about it now has my clit throbbing. I recorded audio of the whole thing :)
