Wow, they're all so hungry for sex. They really can't wait, the energy just goes out of them. With such a hard blowjob you might as well kill your girlfriend, you have to be careful with these guys. In two phalluses at once, that's what I understand guys in the shot, it's a double punch. They were really grinding all her holes, and the rate of grinding didn't drop until the end of the threesome.
An instructor should develop the abilities of his female students, notice their inclinations and act in that direction. And this maiden was best at playing the leather flute.

She's a great girl. I'm in love with her too.
