Persuading The Professor

Clarke Kent slumped in his office chair when Kimmy Kimm walked in. She needed a better grade. He told her straight—assignments stayed the way he scored them. Kimmy stepped close, slid her palms up his tie, and said she could work out that tension if he might budge on the score. Clarke tried to wave her off, reminded himself who was in charge. Kimmy stepped behind the desk anyway. She peeled her sweater off, then the tiny shorts, until she was stark naked, skin gleaming with slippery oil. She climbed onto him right there, slid her tight, greased body over his, belly to chest, nipples dragging, slick thighs straddling. Clarke felt his cock thicken right under the zipper. Kimmy grinned, pressed harder, rocking hips slow, that oil turning every grind liquid. "Stand up," she ordered, and when he did she worked his pants down in one go. He was rigid, twitching. Kimmy sank straight onto his lap, smooth as warm satin, sinking an inch past his swollen head. She teased—edging lower, pausing at the tip, working every muscle along his length. Clarke lost the last shred of hesitation; he grabbed her waist and drove in deeper, breathing against the back of her neck. Every push-pin slide had her arching and moaning louder. She told him this cum-rescue would earn his forgiven assignment, and that dirty brag sent them both over, slick and shaking, until Clarke gave the yes she'd angled for from the start.
