Recently, when I have been getting incredibly horny, I have put on a jockstrap with a cup on the inside. The cup I use is a couple sizes smaller than I would actually use for practical reasons, and so is the jockstrap. This causes my un-erect dick to be trapped inside the cup, and it can't get very hard. I then lie on my stomach and press my crotch against a pillow or a bed/sofa (fully clothed) and watch porn. I am able to move my hips around a bit to somewhat stimulate my dick, and it feels great. I do this for a few hours at a time before moving on to actual masturbation. The result: a cup FULL of precum. It's the hottest thing in the universe. I just sit there collecting my own precum for hours. Anyone else do anything like this with collecting precum?
