I'm not popular with girls, so I really want to have sex, so I ask my childhood friend! She says it's ok if I do it over my pants without penetration! However, she says, "I'm embarrassed, so is it okay if I do it from behind?" I can't be greedy! Then I press my erect penis over her pants and start rubbing it with my penis without penetration! Then my penis goes deeper and deeper into her pants... My childhood friend's breathing gets rougher and rougher... I can't hold back anymore, so I violate the rules and insert it!
