Melanie put both hands – her wrists crossed – on the pylon in front of her as she pushed back onto him. His erection was shaped just the right way, thick enough to stretch her to the point of pain. He slammed ferocilously into her as her mind flashed through the usual list.

It started, as usual, with her high school English teacher, who had required her to stay after school for “tutoring.” She could still feel the pinch of her punctured virginity as pain and pleasure swirled. Her list moved quickly to her best friend’s brother and then the guy who helped her move into the dorm her freshman year of college. Next was the one professor she'd slept with to get the grade she needed and who had surprised her with his talent, and then the two longtime friends she thought of as brothers, which made the impromptu tryst seem almost like incest.

“Don’t stop,” she groaned, returning to the present to feel him again. His fingers dug into her skin as he grunted and gasped and for a brief and glorious moment the images vanished and all she knew was that she was being fucked by a stranger with a perfect cock and rough hands. She stared at the sand between her toes as she felt every bit of him within her and it was almost enough.

“Harder,” she begged, letting the words carry her away. “Don’t be gentle. Fill me. Use me.”  And then, through teeth gritted, with overwhelming pleasure, “You’re so much bigger than my husband!  So much bigger...”

“Than who?” he exclaimed, and nearly stopped, but he was unable to hold back.

“It doesn’t matter. Just harder. Fuck me harder. I want to come on your big cock.”

“You cheating slut,” he growled, instantly slamming into her before holding himself deep within her. “God, but you’re perfect.”

“Yes!” she screamed, feeling him bottom out within her, her sheath holding him tightly as she began to come. Her knees buckled but he held her up while she clenched and shook. He withdrew and then thrust once more at just the right moment to make her come again, her fingers now between her legs as she squeezed her eyes shut and pushed back.

“Should I pull out?” he gasped, struggling to control his own climax, stroking languidly in and out.

“No,” she moaned, trying to reach back and hold him there. “Inside me. Come inside me.”

“Oh god,” he yelled, pulling her to him so hard that she nearly fell. And then he was erupting within her, filling her with his come as he kissed the back of her neck and bruised her hips with his tightening fingers.

“Keep going,” she implored, feeling one last orgasm roll through her as she imagined everything all at once. I’m fucking a stranger, she said to herself; her mantra set on repeat. I’m fucking a stranger, and David doesn’t know. I’m fucking a stranger; he’s coming inside me, I’m letting a stranger fuck me and come in me, I’m fucking a stranger….

And then it was over, his torso resting on her back as he gathered his breath. Melanie braced herself for the impending loss, holding her breath as he pulled out. Her toes were covered in the early morning surf as the tide came in, and for a long time she did not move as her mantra cycled over and over in her fevered mind.
