Spicing Up a Marriage

The lab door swung open, and the couple walked through the doorway, ignoring their son (who was sitting in the torture chair and witnessing it all) and heading for the table.

Fritz sat Katherine on the cold, metal surface. She purred into his ear, "I want you to treat me like your experiments... throw me on the table and do me all night long..."

The cybernetic doctor couldn't say no to his wife. He slammed her down on her back, spread her legs, and rammed into her pretty little pussy. She forced his hands to clamp onto her hips as she looked him in the face.

Katherine was in ecstasy. "Harder! Fuck me like an animal!!!" she squealed, "Mmm, make me gush like a fountain!"

Fritz obliged, pounding her tight, pink hole, making his beloved scream in pleasure. His cybernetic eye began scanning both of their stats. 

Katherine~ Heart rate: 180 bpm| Pleasure: 99%| Time until orgasm: T-minus 0.2 seconds

Fritz~ Heart rate: 175 bpm| Pleasure: 99%| Time until orgasm: T-minus 0.2 seconds

Fritz leaned in, continuing to fuck the holy hell out of Katherine, and locked lips with her. At that exact moment, the two were hit with simultaneous orgasms. Katherine screamed into her husband's mouth as her blue eyes slammed shut. She was overfilled again, spraying another cum cocktail everywhere.

As the couple began to relax, Katherine gave Fritz a kiss on the nose. Fritz laughed between pants, still holding onto her.

"I'd appreciate it if you let me get up."

Fritz slipped out of her and picked her up. He panted, "I'm... I'm starting to crave something pink again... Wanna go for the couch this round?"

"I don't see why not," Katherine cooed as she was carried downstairs.

Their son (who had heard everything) was pale in the face; his sapphire eyes the size of baseballs. He inhaled deeply... and his horrified scream reverberated throughout the castle.
