Something Up Your Sleeve

Remaining fully clothed, unzip your fly, pull your underwear down just below your balls and pull your cock and balls out through your fly openning. Get an erection, then cover that by inserting your cock in the sleeve of an old shirt. Jack off into the shirt sleeve bringing yourself just up to the point of no return and repeat this several times. Be aware of the sensations created by the clothing covering your entire body, then when you are totally into it, jack to a thrilling climax up your old shirt sleeve.
