I am becoming very attached to this masturbation technique that involves using a condom.
I unroll the condom a little so can I can pour in a water-soluble lube (I like Astroglide) to a depth of a little less than 1-inch. I then slip the condom over my erect cock. The lube remains in the end of the condom around my cock head, but some initial stroking causes the lube to evenly distribute itself through the length of the condom.
The lube is contained within the condom and doesn't leak out because of the snug fit around the base of my cock. It instantly heats up since it's in a contained space surrounding my warm cock.
Stroking my cock now feels very much like it's inside of a warm, wet pussy. The wet, slippery feel is completely different from masturbating in the 'usual' way. Lying on pillows, with my cock snugged between them, further adds to the illusion of fucking.
