I just got my report card back and I failed a bunch of classes but I don't want my mom to know. I have to show it to one parent to get it signed though so I tell my step dad. I know I'm gonna be able to convince him to keep it a secret so I start rubbing his cock over his pants and kissing his neck but he keeps talking about being married to my mom and that this isn't right but his dick is so hard I know he wants it. I pull his cock out and start jerking him off and he's scared my mom will find out but I tell him I won't say anything. He thinks I'm just gonna give him a handjob but I start to suck his cock and he says my mom never does this for him. I keep taking his cock all the way down my throat and getting sloppy all over him. I take my top and my bra off and he sucks on my tits and says he never knew I did these things but I tell him I can do more and get him on his back and start licking his asshole while I stroke his cock. He has me take my panties off so he can eat my pussy and I suck his toes at the same time. I'm able to reach and stroke his cock while I do it too. He pulls me on top of him to 69 then flips me on my back to finally see feel what my pussy is like. He fucks me so good but he says he still thinks it's wrong but that he can't say no to my pussy He pulls out and has me ride his cock until I cum then I get off and throat his cock again. He gets me in to doggy and pounds out my little wet pussy. Then he gets me on my knees on the floor to suck his cock and his balls until he cums in my little mouth and I swallow it all so we can keep my bad grades a secret from my mom.
