You walk in on me and see me humping my pillow while watching a video on my phone. You stand and watch for a short while, smiling. You finally come in the room properly and I see you... I'm so shocked fumbling with my phone, "Daddy, what are you doing?" You are like what are you doing?? "Daddy, please don't be mad" I start stuttering while you stand there patiently waiting for me to explain myself.. "okay so Daddy, I just was watching a video of a girl riding cock and I was trying to practice. All my friends tell me how good they are at riding, how good it feels, how they always make their bf's cum and I just don't know how to do it" You tell me that will let me ride you if I don't want you to tell Mom, I think about it, I really don't want Mom to find out and maybe that could work Daddy, you could teach me a few thing's. So I agree, lay down Daddy and let me ride you, soon as I see you cock Daddy, I'm a little scared, Daddy it's so big, you tell me it's fine just take your time. I slowly get on top and slowly slide it in... "Ohhhh Daddy it's really big" you just say its okay it will slowly stretch you. I start riding you and taking deeper and deeper, you tell me what to do and I try my best. You tell me to play with my clit "is that going to make it feel better Daddy?" I do it and omg Daddy it feels amazing, I take your cock out Daddy and rub all over my clit, stroking you harder and faster... I end up cumming so hard all over your cock Daddy. It feels so good. I keep doing everything you tell me and it feels amazing. You tell that you want to cum inside me.. "Daddy but I'm not on birth control, Daddy please no" you tell me if " you want me not to tell your Mom you allow me to fill your pussy with cum" I agree because at this point it feels so good and anything for you to keep my secret. Daddy you fill up my pussy, wow I have never had anyone fill me up before and it feels so good. I ask you "how did I do Daddy?" you tell me that "it was amazing and I'm going to be a pro" this makes me so happy. I love you Daddy.
