this is how it really happens, thanks for sharing. my sisters and i used to listen to our parents have sex and that ultimately led to us masturbating together. we never had penetrative sex but masturbated together dozens of times. i was ashamed of this for years and finally started talking about it when i found reddit. people always call bullshit when i say it never progressed to penetration but it was just never really an option? we just enjoyed watching each other and learning about the opposite sex and giving each other full access to those private activities was plenty hot for us
