Masturbasi kilat sambil masturbasi di ruang penyimpanan

I do a quick Hump Masturbation on an old Storage totally naked and rubbing my Penis on a styrofoam plate. Because of the strong friction I come very quickly and therefore not as much Sperm squirts out. But the satisfaction is very good.But some of the Sperm is still on my Belly and on the edge of the glans.
