When you are making love to a bitch from behind, you grab on to her hair and you insert your penis into her anal cavity. After 8secs. of riding her, your friends jump out of the closet and block her as you make an escape with your clothing.
When you are doing a girl from behind, holding her ear lobes and pulling them hard when you're about to climax you tug as hard as you can and yell out "Woah easy girl!"
I was doing my gf and I performed a stallion rodeo when I climaxed, she stared and me with an angry face I couldn't help but laugh!
