You just moved in with a friend of yours into a new apartment, and one day you walk in and catch her touching herself… she’s embarrassed at first but then asks you to show her the ropes on sexuality as she’s never had sex before. 
You bend her over the bed and take her virginity, making her your little slut. She loves your cock in her pussy so much, you then talk her into letting you fuck her ass. She’s gonna want your cock all the time after this..
