I want you to try this next time your trying BTC and let me know how it goes;
Lay on your bed on your side in the crash position (not fully but on your side with both legs bent somewhat towards your chest), spread em’, pull your cock and balls together over the leg that is making contact with the bed (so the balls are hanging out of the way).
Grab your whole package from around the back (your hand between your legs coming from the rear) pull it through very firm, then do the “man-gina”. If you can get a good grip around the base hold it, and then straighten your legs down/out.
You should be able to work it out whilst you are doing it, basically the idea is to get a fucking awesome stretch using your legs and nothing else.
Or try this; Lay on your back with your legs bent (about 80-90degrees) pull and stretch Peter Johnson and then hold him with your thighs (you should be able to see your whole shaft stretched), then straighten the legs.
Its all about leverage. It’s all about the best grip possible; your skin. Good luck experiment with this shit and stretching doesn’t really become part of your routine anymore, it is something you can do whenever you are lounging around in bed.
