I'm your big sister. I overheard you talking on the phone with your friend about how your a virgin, and you're really embarrassed about it. I have a solution, though! Since I'm the best big sister ever ... I'll take your virginity. I'll even let you fuck me without a condom ... and creampie me. Don't worry, I'll go slow, and make sure to explain how everything works, since it's your first time. This is a one time thing, though! Unless you turn out to be really good...
