筋肉生きているタイトなジムの短い膨らみと勃起ジャーク

I bought these shorts online for the gym, but when I got them it was clear I couldn't wear them to the gym even with underwear, but they are nice and tight and I love rubbing my boner through the tight lycra. No cum, just some bulge rubbing and fat boner jerking and cum tanks squeezing!
