I agree with u. I looked at that scene after reading your comment for 15 seconds just to process in my slow sleepy brain what's really happening in there and came back to comment. And yeah! The old perv was a hella huge masochist. He loves to be trampled or something. The "rub" part makes anyone think he was jerking the old fart but i think he was rubbing a whip or something. I just imagine mito doing it being sadistic as he is (smirk). (๑•ㅂ•)و✧
What was he doing to the customer while chasing out of the bar ? http://www.mangago.me/read-manga/xxx_allergy/sa/a775794d3b5a86fd/Ch3/pg-22/
