My girlfriend's stepsister and I seduced her into a threesome

The plan was foolproof. I had been eyeing my girlfriend's stepsister for weeks, plotting to seduce her into a steamy threesome. Finally, the day arrived and I was ready to make my move. I invited her over under the guise of hanging out, but my real intention was to get her naked and begging for more. It didn't take much to get her revved up. She's a total nymph and she was eager to explore her wild side. We started off with some teasing, taking turns licking each other's pussies until we were both dripping wet. Then, I unleashed my monster cock and she eagerly took it in her mouth, nearly choking on my girth. My girlfriend joined in, getting a taste of the action. Soon, the brunette beauty was bent over, getting pounded by my thick shaft while my girl licked her juicy pussy. It was a full-on, no-holds-barred fuck fest that left us all breathless and satisfied.
