It had been five days since Ava snapped the weird penis cage contraption on me, and I was starting to get really desperate. At uni, my mind kept wandering to sexy stuff and I could feel the strain against the cage. I wanted to rub one out but even the semi-boners were painful.
When I got home that day, she was wearing a thin blouse that was barely hiding her bra. My breath caught in my throat as I felt a tingle down my spine that told me dinner across from her might be more painful that I'd hoped. Her eyes glittered as she saw me struggle to keep my cool. She's enjoying this way too much for my taste.
It started as a joke - she said she'd have to keep me caged in order to tame my constant arousal (and subsequent masturbation) - but it turns out she was more serious that I'd thought she would be. She bought the cage and when I laughingly agreed to wear it for a few days, I could tell the mere idea was getting her off. Even though I'd been sexually unfulfilled the past days, she'd been getting it all. She made me lick her until she came every night and most mornings. I hadn't realised it before, but I suppose I had been pretty selfish in bed up until now. I was paying for it dearly.
After dinner, Ava told me I might get a treat, so I did the dishes as fast as I could and rushed upstairs, where she told me she'd be waiting. When I got upstairs, she was lying there in a sheer black nightie. My blood began pumping towards my loins immediately. It would be seconds until it would start to hurt.
'Darling, will you please take this thing off me now?' I asked. 'It's gonna get real painful if you wait too long to take it off'.
She smirked and spread her legs. 'Who said anything about taking it off?'
