We've been close friends since elementary school, a trio of childhood buddies. One of them, Kei-kun, confessed to me and we started dating. However, I had never dated anyone else before and honestly didn't know how great sex could feel. Of course, I hadn't seen any other penises besides Kei-kun's. But... I encountered a penis that reached all the way to my belly button, and my vagina stretched wide open. With each thrust into my womb, I understood that I was being driven to ecstasy, bordering on madness.
