I'm not good at explaining but I'll try..
I meant leaning your body on a chair as much as possible, by body I mean upper body. just lean your body against the chair. Like, sit very relaaaxed like sometimes you lean on a couch, that position lol. If you have those flexible office chairs then it's better cause you can push back on the chair. Try to have your ass as close to the corner.. lift your lower body (from your ass, thighs to your toes) up against the wall and pull down on your dick from the back of your thighs...now if it made sense to you I hope you'll like the idea...again my english isn't too good...
I love this way of
BTC I'm sure everybody else will as well...it's just too comfortable to grip and pull
