Niece by marriage

(Fantasy story) My sister in law years ago had started a new job and didn’t have nobody to watch her kids so she asked me and my wife if we could babysit them on an everyday basis while she attended work we said sure we didn’t mind her oldest child at the time was nine…teen beautiful young lady cute smile petite smooth legs pretty toes soft soles cutest pussy her name is Cruz she often took care of her 2 younger brothers and little sister she played teacher with them a lot and dressed up like a teacher would love to try on my wife’s pair of heels coming in and out of my room going in my closet trying on different kinds of heels I’d be in bed sometimes master bating well at least trying to quietly I could tell Cruz was curious of what I was doing serval times everyone in my wife’s family is aware of my fetish for feet including my niece Cruz one day I was extremely horny stroking away my hard cock when Cruz walks in calmly and quietly in my room when she walked in she couldn’t help but to lock her eyes on my phat cock throbbing before her eyes I stroked it maybe 8 or 10 times until I realized she was watching me and tucked it back in my shorts Which heels do you like better on my feet uncle she quickly asks as she approached my bed where I laid I sat up as she sat next to me closely I could feel her energy her curiosity I wore thin basketball shorts that showed my dick print I don’t know what made me do this without thinking I firmly grabbed her hand and placed it on my cock while touching her legs as I put on different heels on her pretty feet playing with her she didn’t move her hand she kept it on my cock as I went back and forth with my finger tips rubbing her little pussy Cruz and her brothers began to sleep over a lot during the weekdays and I knew she slept in her underwear one day I walked in the room to check on the kids if they had fell asleep I found Cruz legs wide open showing her pussy lip and got real curious I slid her panties to the side to get a good look and got real hard when I seen her pussy I began to stroke my cock on her soles she opened her eyes and looked me dead in mines as I was rubbing her pussy spitting on my hand to make it wet she didn’t look mad or show much emotion so I kept at it I moved toward her face with my cock on her lips sliding the mushroom tip inside her mouth feeling her tongue do a circle motion around it which had me damn near about to cum in her mouth so I backed away and busted my nut on her soles I wiped it off bent her over and rubbed my cock on her pussy and asshole (made up story)
