The feeling of her hands fumbling around my groin and slowly undoing my chastity device made me weak. I took an excited little breath every time she intentionally brushed her nails over my balls.
It had been two weeks since Jen had let me out of my cage. Two weeks of teasing and tantalising, two weeks of frustration, two weeks of complete torture at times. But I enjoyed every minute of it.
The second of those weeks, Jen had been on her friends hen party in Spain. She had hidden the key to my cock cage, but she wouldn't tell me where it was. This added to the eroticism of it all.
So upon her return, not only was I very excited to see my wife after a week, but I was particularly excited for her to 'set me free' so to speak.
The rare feeling of freedom flowed through me as my cock slowly sprang up to semi-erect in just a few short seconds. Jen stood back and giggled.
My mouth dropped as I watched her seductively pull her top off to reveal her big, round, pert tits to me. She pushed me back onto the couch and hiked up her skirt, showing me a glimpse of her thick, dark bush, before straddling me.
My now extremely hard cock stood firm, as my wife began to rub her wetness over the tip. I stared deeply into her beautiful brown eyes, our mutual lust, intense and serious.
Jen took a breath and lent over to pick up her phone.
"You've got five minutes," She said, turning it to show me the timer already beginning to count down.
"Only five?" I moaned as her cunt lips began to engulf my cock and she let all her weight down on me until I was all the way inside her. Jen nodded as she began to fuck me.
Her moist pussy felt amazing as she bobbed up and down on me enthusiastically and our breathing intensified.
"The rules are," she said in between breaths. "If you can cum in five minutes, then, well... you can cum." Jen smiled, shaking her long, dark hair from her eyes as she fucked me. "If you don't cum by the time the alarm goes off, "then it's back in chastity for another week."
"Holy shit," I said, in complete awe of my beautiful wife.
"That's not all," she continued. Her tits bobbing up and down in front of my eyes. "You cum, you clean it," she said. "I mean you lick it all out of me and make me orgasm as you're doing so."
"Oh my god," I said, I had never felt hornier in my entire life. I looked up and noticed the wry smile on my wife's face as she continued to writhe around on my cock.
"Also, next time will be longer." Jen said. "You cum now, I'll lock you up for another month without release."
"I... but," I protested.
"You hold on until the alarm goes off, then I'll let you back out in a week and you can have me again."
"I... like the sound of that." I said, desperately trying to hold the cum in my balls as she fucked me.
"Three minutes," she said, not letting up. My cock slipped easily inside her soaked hole, her arse thudding down and slapping against my thighs.
