Its always better for a girl to have your first threesome with someone other than your boyfriend. that way you can practice to get it right for your man, without the nervousness.
Being the helpful, self-sacrificing person that I am, I volunteer my services. They can come over, with their own condoms, lube and beer to keep me hydrated of course, and I will help you out.
check your pms for my address. You can wait in the car.
