The Twisted Sister

When you take a woman into a restaurant bathroom for a blow job, and right before you cum, you twist her around and cum directly onto the back of her head and into her hair. You then rub the cum into her hair like styling gel, and make her look like Twisted sister.

After I turned the girl I met at the bar around and gave her the twisted sister, I immediately sat down on the toilet and started taking a shit while she was still in the bathroom!!

Sister

Usually a wild or untamed animal, capable of anything. You must steer clear of their path otherwise you will meet your demise. Pack quite a punch at times of anger.

Your sister destroyed the universe, oh no.
