My step-sister convinces me that she's not a lesbo by sucking my cock

Some angels sometimes have a hard time transitioning to actual womanhood when puberty kicks in, u know. It's a familiar thing. Some of 'em will have a hard time accepting their recent feminine bodies. The bigger boobs and all that. So, they resort to wearing large ass baggy raiment that conceal them and make them look androgynous, as they looked before the hormones kicked in and all was fine with them. Well, my gorgeous step-sister was like that, obviously. I mean, I have not at any time seen her wearing any feminine clothes, and I was honestly starting to think that after all this time, that babe became a lesbian or something. Honestly, I have no Idea, I guess this sexuality thing is just different for everyone. Teasing the tomboy over it obviously worked out well for me eventually, because that babe just snapped this day and pushed me down to the ottoman and decided to prove to me that that babe is no lesbian. That babe craves dick just as much as any hotty out there. Honestly, I was overjoyed by this. Not that I cared much about someone's sexuality, it wasn't like this at all. Rather, I was just cheerful that this babe decided to convince me that I was wrong like this. So as I said, that babe snapped and pushed me over to the bed and started engulfing on my cock vigorously and this babe was making me drip in pre-cum. My heart was pounding insanely hard as she sucked on the sip gently and then moved on to full-on deepthroating. My sister was eager to prove me wrong and show me just how much she loved cock. We moved on to some hardcore doggy style fucking right next to the door with some occasional sweet kisses. When our daddy came knocking, that babe opened the door and talked to him during the time that I was fucking her behind the door. That babe might have dressed like a butch lesbian, but this babe fucked like a crazy whore! We went back to the bed, since it is more comfortable there. From here on, she just rode me till we came.
