When I went to my girlfriend's house to hang out, I was surprised to be greeted by her beautiful mother and sister! As I was excitedly chatting away, she suddenly said, "If you become my boyfriend, we'll have a sperm test!" She started stroking my dick and then the sperm test began for both her and her family! Apparently, a boyfriend needs to have high-quality sperm, and the sperm test is a way to actually check that. Naturally, one shot isn't enough, and I end up having to do it multiple times! And it's a P2M slut...
