Well this is something I did when I was horny out of my mind. I got totally naked and laid a towel on my bed...then I took some hair gel and put an excessive amount on my leg. Then I began rubbing the hair gel all over my balls and my shaft stroking some as well. Then I happened to remember a bottle cork I had found, and saved, so I used my other hand to put some gel on my ass as well. I kept stroking nice and slow the feeling is so nice and slick with gel on my balls and between my legs and butt cheeks.
Now I spread my legs and rubbed the cork into some of the gel on my ass and then slowly pushed the cork till it got sorta locked in place. Then I put my legs close together and squeezed my butt cheeks together as I stroked slow till I couldn't stand it and wiggled my hips so I could really feel the cork and stroked super fast...I had an amazing orgasm and shot a hot load of cum onto my stomach. Give it a try guys! Hope the ladies also enjoyed the idea.
