He catches her, smirking, and she blushes, her nipples hardening against her shirt. She excuses herself, retreating to her room. He follows, finding her on the bed, skirt hiked up, fingers dancing on her panties. She looks at him, biting her lip, and he approaches, kneeling, pushing her legs apart. She gasps as his tongue finds her clit, her hips bucking as he devours her, her hands fisting his hair. She tastes herself on his lips when he finally pulls away, panting, his cock straining against his jeans.
