He takes her with his massive cock.

As the Kingpin pushed into MJ's tight, wet pussy, she couldn't help but let out a cry out pain as her walls were stretched. She'd never had anything this big in her before! She felt like he was going to tear her in half. Her lips were silenced by a greedy and hungry kiss. As he buried his cock into her cunt, moulding it to fit him, his tongue entered her mouth, dominating her.

She moaned against his lips as her eyes rolled back. Pain and pleasure crashed into her like the waves of a squall. Then, he began to move. His cock slowly started to piston in and out of her. She felt every inch of him rub against her walls.

Mary Jane had never felt so... full before. Peter was no slouch, but this was something entirely different. To her chagrin, her body shook and shivered as she climaxed. He broke the kiss and looked down at her in triumph. "Did you cum from my cock, Ms. Watson?"

"Y-yes, sir. It feels so..." Good. She finished in her mind.

Truth be told, he was quite close. While her mediocre blowjob had built up a little excitement, her words and the taboo nature of what he was doing with her caused the arousal to build in him tenfold. He pulled out, a small, disappointed sigh accidentally escaping Mary Jane's lips.

"On your knees, Ms. Watson. Time for me to paint you with my seed. Beg for it. Tell me how much you love my cock and want my cum and this will all be over." He stood back and stroked his cock in front of her.

You're at the finish line, MJ, she thought as she got on her knees in front of him. She squeezed her ample breasts together and looked up at him. "Please, Mr. Kingpin! Give this slutty, cheating wife all of your cum! Cover me in it!"

With that, his floodgates were released as he came on her, covering her face and tits. Rope after rope of his hot cum splashed onto her perfect skin— and some in her mouth. Finally, it was over.
