That happens to me a lot. You need to either put a cut garbage bag underneath the sheets or get a bunch of absorbable pads. They're cheapest if you order from China.
I love men to wrap it, because I get so horny when they start cuming, thinking that they are using me to fill that tip on the end. There is something about a man filling a rubber with his load that turns me on and gives me an orgasm. I cum a second time when he pulls out, when he is done using me, and shows me the full tip of cum.
