In the dimly lit living room, Robin's heart races as she gazes at her stepfather's bulge. She's never felt this way about him, but the thrill of the taboo is irresistible. Sinking to her knees, she frees his hardening dick, her small hands barely able to wrap around its thickness. Robin's first lick is tentative, her tongue barely touching the sensitive head, but as she gains confidence, she takes him deeper, gagging slightly before pulling back, her eyes watering with a mix of excitement and trepidation.
