The colon is very long. When a guys arm goes in, the organs are pushed aside a bit. I’ve been up a guy to my bicep. You can feel his heart beating. His dick was soft but it was running with precum. The trick is to go VERY SLOWLY and take tirection from the bottom. It’s done ON HIS TIME! He’ll relax if he knows he can trust you. As you go in be sure to stop when he says so or if you feel resistance. Hold still. Let him take a few deep breath’s and many hit the poppers. You’ll feel him open the next sphincter and you can slowly move deeper. You can repeat that 2 or 3 more times until you reach the point where he says no deeper.
the go even slower on the way out!
I learned this from the guy I went into up to my bicep. I used this technique to be able to take a fist up to the guys elbow. It was HOT AS FUCKING HELL. I love Fisting a butch guy, but I LOVE GETTING FISTED BY BUTCH STUDS WHO TRULY LOVE STICKING THEIR HANDS AND ARMS UP A GUYS ASS!
the body can take it if you GO SLOWLY!
