When I was like 14 I got my first blowjob. Girl was getting all freaky and I'd been working out before hand.
I popped into her moms bathroom and first thing I saw on the counter was rubbing alcohol. I squirted it all over a paper towel, soaking it down good and rubbed my balls and anus in four quick, aggressive motions.
Most painful experience of my life, I dropped to the floor and rolled around. My ass hole literally felt like someone stuck a hot poker in it. Balls were on fire.
I came out of the bathroom and she laughed and said "have you been crying"?
