Tried to do this for about 45 minutes. Got one hell of a workout. Am below average 5” or 12-13cm. Could reach my hole; but as I am uncircumcised, every time I went to push in my skin would contract and push my head back toward my balls. Also the angle may have been a little far to reach back/upward…. But I came just from trying; with even jerking off beforehand.

Love this video. I’ve tried to get my cock into my anus like this but its difficult. But despite this, no hard and no wanking I came just from touching my cockhead against hole. It was delicious.
