Klaus

She was smirking at you. Your honeymoon had taken an odd turn after yesterday afternoon.

You were at the beach with Sai enjoying a relaxing afternoon. Your wife was looking fine as hell but there were gorgeous women.. everywhere. You couldn't but stare and when your wife came back after a bathroom she saw you had developed quite the boner.

She didn't say anything but that night when you got back to the hotel room and were hot and heavy making out before having hot passionate sex for literal hours.

You made sure she was satisfied and she was much the same. It was an amazing night of passion you would not soon forgot. She would make sure of that. She was atop of you and slowly let your fading erection slip from her pussy. She then climbed off and came back with a scarf.

"We are not quite done yet, my love." She spoke in sultry tone as she climbed back atop of you.

"Baby... please.. I'm spent." You reply but allowed her to tie your hands to the bed anyway.

"Don't worry. You don't need to do a thing." She then said after securing the other hand. Then she climbed off the bed yet again.

"Now.. I have to mention something, my love." She began, fetching something hidden deep in her travel-case.

"W.what?" You said, getting a little bit nervous.

"This afternoon. On the beach when I was away for a while. When I got back. You were hard as a fucking rock. Glaring at all those other women." She started to explain.

"Now.. its only natural that your body reacts like that but... We are married now my love and I deserve to be the only woman you get hard for."

"W.what are you saying?"

"I am saying that I will be the only woman you will ever get hard for now on." She replied calmly. A rush a heat shot through your body when you saw Sai holding a chastity device. A sold steel cage designed to keep your cock locked up.

"N.no.. Sai.. please.." You started to beg while Sai was already sliding your balls and slowly growing erection through the ring. And then she pushed the cage onto the tip of your dick and forced it into submission.

Then with a soft click your dick was locked away.

"Baby.. please.. no.. take it off." You begged her again already feeling this odd arousal spread through your body as your dick tried to get hard.

Sai slowly shook her head, rubbing her naked body all over your chest driving your wild with lust.

"No... its locked now. It will only ever be big and hard for me alone... and only when I allow it, my love." She whispered in your ear before she passionately made out with you.
