You get to choose a companion for the weekend from between two women. Whichever you chose, she will do her very best to be your perfect girlfriend and do whatever you want for your time together.
Both women are your DS. Whatever you most desire in terms of race, eye color, tits, ass, weight, personality, etc, she is whatever you like most in a woman. Both are a 10 to you, or at least as close as a woman can realistically get to that ultimate level of perfection.
There is really only one difference between these two women. One just turned 18. One just turned 40.
Everybody knows which one I would chose, but how about you? Which woman do you chose for your rent a girlfriend?
