When everyone's flights got canceled and it would just be us for the weekend, I could never have imagined what it would turn into... But there we were, just you and me, alone in the house. That first morning, I padded into the kitchen in my tiny skimpy PJs. Your eyes seemed to keep drifting. You kept eyeing the thin tank top barely containing my heavy tits, my nipples poking through like naughty secrets. I saw your cock twitch and harden instantly in your boxers, bulging obscenely. The look in your eyes betrayed your deeper feelings. Before I could protest, my pussy was already dripping wet. You yanked down your shorts, your hard cock springing out. I gasped, "We shouldn't..." but I couldn't deny how it made me feel. Wrapping my soft lips around your swollen head, sucking greedily while you groaned. You pulled me up, pulling my panties aside, and pushed your rock-hard cock deep into my soaking pussy. Pounding me wildly, until you exploded, flooding me with ropes of cum, leaving me trembling and leaking down my thighs. That night on the couch, we couldn't stop. Something had changed and could never go back. As I straddled you, grinding on your hard cock, the sound of the car pulled up. They're here! The group showing up completely unannounced about to burst through the door! We scrambled apart, hearts pounding, my pussy still dripping, pretending nothing happened while making small talk. Sneaking away to the bedroom, I whisper "Come quick, I need that cock." You pin me face-first against the door, hiking up my dress and thrusting your raging erection into my cum-slick cunt from behind. I try to keep quiet, but can barely stifle my moans. With your hands squeezing my ass as you drill me, your StepSister surprises us by knocking on the door, yelling. Freezing mid-thrust, your cock still throbbing inside of me, I have to lie to her, "Yes, I'll be out in one minute!" Fuck, do you think she knows?
