The more popular a girl is, the more likely she is to put the other person into the category of someone she's willing to do it with once. It's fine because she can do it. Momo seems to be the type who gets attached to you once you make her cum in sex. Her inherent junior nature and her huge breasts match up to give you the best service ever. I don't understand why she wouldn't give me a titjob with those boobs. Also, we're meeting because we both want to do it, so we've built a mutually convenient sex friend relationship from the beginning, so it feels good because we don't have to be shy. It seems like Momo likes it because she can feel good without worrying about it. It seems like she's embarrassed to ask her boyfriend to do things she wants to do, so doing it for her is like a thank you. If she climaxes too much, she loses her sense of things and seems to want to just cum, so it always ends up being a creampie.
