F orcing The Abs Hi guys So this is a fan request Basically the idea was to give my abs almost no chance to relax by doing different exercises and immediately punching my abs - in this way extending the contraction even more I added the nipple clamps to make it even harder At some point however I noticed that my nipples were a bit slippery I shouldn t have put some creme on in the morning so I decided to resort to liquid chalk which allowed the clamps to sit as tightly as never before ouch Have fun video length 13m 9s
