I'm 22 and my friend since 9th grade keeps asking me to have a threesome with her and her boyfriend of about 8 yrs. Whenever I sleep over at her house they constantly bring up the subject after all our kids have gone to sleep. They say my body shape, personality and the way I look keeps turning them on and it's getting harder for them to control themselves around me. I don't wanna do it but I enjoy going around them because we all have so much fun with game night and our kids love playing together. What do I do??
