Young girlfriend of my stepmom gives me a hands-on lesson in sex

I've been eyeing my stepmom's stunning 18-year-old girlfriend for a while now, and when my stepmom was out of town, I knew it was the perfect opportunity to get down and dirty. Her friend had been teasing me relentlessly about my skills in the bedroom, so when she offered to give me a hands-on lesson, I couldn't resist. She started off by giving me the best blowjob of my life, her small mouth expertly handling my big cock. Then, she straddled me and rode me like a pro, her tight pussy sending waves of pleasure through my body. We were both young and inexperienced, but our passion made up for it. The way she moaned as I fucked her, the way her body convulsed with pleasure, it was all worth it. We were just amateurs, but our lust made our lovemaking as hot as any professional couple's.
