Go visit the woman across the corridor

You might not be able to stop this bloke from fucking Jane, but you can at least give him a taste of his own medicine by forcing him to watch you freely use his own wife.

Jane calls you to you for help with more and more desperation in her voice as you leave the room, "John! John! John Doe!" Eventually her screaming is silenced by the mans mouth on her own. He forces his tongue into her mouth, but your attention is now elsewhere.

"Hey there," you say as you enter your neighbors room. "I'm John."

The woman turns from the TV to face you. She's younger than you thought she would be. She seems to be a couple decades younger than her partner. She looks over your shoulder into your hotel room before she introduces herself and frowns.

"Oh, so now he's fucking your wife?" She says and frowns.

You look and see that both Jane and the man are naked... and yes, his cock is inside of her. She doesn't even seem that upset by it. She learned the whole free-use concept pretty quickly, after all.

"Yeah, and so I'm gonna fuck you," you say proudly, like you're dropping a big bombshell, but she just shrugs and then tosses you a bottle of lube.
