Last summer my mom grounded me for talking to a boy on the phone. I was so angry I decided to seduce my step dad to show her she cant stop me from doing what I want. I started to wear my younger sisters clothes (shes 10 and I'm 13). So on the first day I wore her low cut vest its sleeveless and didn't reach my pierced belly button. I didn't wear a bra and I'm a 38-C my mother wouldn't dare let my out the house like this so I waited till she left for work. I also wore her white micro shirt with no panties underneath. After breakfast I was careful enough to make sure both of us came done the stairs at the same time i "accidently" dropped my phone on the stairs looked back to make sure he was behind me and bent over to pick up my phone really slowly and made sure my plump nipples came out. I heard him say something quietly to his self. I didn't turn around until we got into the den and we sat down to watch a movie. I sat on the oppisite side I know he noticed my nipples because he keep looking down. I thought to spice it up a bit i'd lay on my side and let my skirt ride up a bit. Steve was looking at my shaved pussy lips that dared to peak out. After 20 minutes I faked a yawn and ask if i can lay my legs in his lap I closed my eyes and faked sleep as I tossed as turn my skirt rode up into my belt and my bare vagina peeked out. When that didnt work i excused my self and said ill be right back. I went into the bathroom and sat their for a minute sat there and un did my skirt button and zipper then I walked back out and noticed him staring at my vagina. 'What?' I aasked he said nothing. I sat on his lap rubbed my clit across his erection. Ugh I moaned and when he asked what I said this feels nice and I said daddy can we watch porn please he said this is our secret brittany. We watched that and my pussy jucies soaked on his pants, sorry daddy I got exicted no problem. We went upstairs and went to our rooms and i told him to come get me in 10 minutes. I cracked my door stripped and masterbated when he came to get me he came to get my I was screamed ohh Steve Ughh and fuck my hard Daddy. He came all the way in and said you thinking about me baby i breathed yes and i said fuck me on the couch. So that way when that bitch came in shed see him fucking me. I looked at the clock i said 12:15 okay my mom will be here at 12:30. We fucked until my mom came home and she was so angry. Her fault for leaving me in the house! :)
