Rubbing face down on plastic sticky beach ball
This may sound a bit weird. But I was driving by a house and saw a plastic beach ball in the trash can. I stopped. And picked it up and brought it home it was still somewhat inflated but not all the way.
I got naked, placed the ball under my cock and started rubbing and grinding on it. My cock sticking to the plastic it felt great. Many tickles. I was imagining who blew it up who had played with it that even turned me on more.
I was thinking about the air inside and the thought of a girl blowing it up gave me even more of a thrill. OMG it tickled so much it did not take long and I blew my huge load of sticky white hot cum all over it. I will keep it so I can rub on it some more later.
