Due to my father's remarriage, I gained a new stepmother and stepsister. While the family was out, I was masturbating alone. Suddenly, my stepsister came home, and I panicked, quickly hiding my cock. Looking tired, she wore sweat-dampened black pantyhose and begged me to give her a massage. Tempted by her soft whispers, I carefully kneaded the soles of her feet. Then, the blanket slipped away, exposing my fully erect cock. She teased, "So you're still a virgin if you get hard just from being watched," joking yet clearly observing every detail. Though she claimed she couldn't do anything sexual because she had a boyfriend, she straddled my cock with her legs and began a footjob. Seeing my excitement, she provocatively kissed me. Unable to resist, I groped her breasts, and she whispered, "No, don't... I'll get too excited." Despite her words, her nervousness never faded. She exposed her pussy over the pantyhose, teasing my clit with her fingers, while launching her own attack. Using her black-pantyhosed toes, she played with my nipples and started sucking my cock. An intense blowjob while I worshiped her huge, shapely ass stretching the black nylon. She initiated grinding against me through the fabric, her sensitive pussy overwhelmed as she pleaded, "Hey, it's not cheating if we just insert it, right? You'll keep it a secret, promise?" Mounting me in cowgirl position, she took my cock inside her virgin pussy, which gushed with first-time arousal—our chemistry so perfect my legs trembled. Climaxing repeatedly, we switched to doggy-style with her legs wide open, then missionary with her soles flaunted in my face, finally drenching her black pantyhose with thick, white cum.
