She's my little sister's best friend.She calls me DaddyShe's completely off limits.And she's mine. My little sister thinks I'm taking care of her best friend while she's away at college.She doesn't know the half of it, though.Yeah, I give Fiona a place to stay, somewhere to sleep.I give her mindblowing O's, too.That place to sleep? My bed. No clothes allowed. She started it.By teasing me.By calling me Daddy.By telling me what a good girl she'd be for me.I finished it by staking my claim and making her mine. Except we haven't told my little sister.We're sneaking around behind her back.So when my sister asks Fiona to go to a "singles only" college frat party with her...Look, I don't want either of them going.Fiona's not single, she's mine. No way in hell am I letting some preppy frat bro lay a hand on my baby girl.
