The day your Master/Owner locks you up in a chastity device and tells you to forget about touching, getting erect, or even cumming for the near future.
You're turned on for a bit right from the get-go and you probably get resoundingly fucked then fall asleep in each others arms. You wake up a few times with some burning or pinching. But, you feel good about living out your destiny of being locked'n'denied as skavecto a Apha male Master!
That's the easy part. Then ...
After a few days you start to miss touching, fondling your cock or as you now think of it your clitty You miss that exciting feeling as it grows semi stiff in your hands. And you say to yourself "God, I wanna cum."
You figure your Master and keyholder will be back on the weekend and he'll let you out. He'll perhaps let you stroke your cock hard and bust a nut whilst he's fucking your hole. But Friday night comes and he's tired from working all week and he just wants to have a nice meal, some cuddling and a good night's sleep.
Laying in bed, spooning with him, you reach behind to feel his cock because you miss the feeling of yours. Even though he's tired, his cock responds ... hardens in your hand. It's then that your cock suddenly swells in the cage ... almost hurting.
He turns to lay on his back and you turn and duck under the covers. You hold his hard cock at the root and bring his swollen, hot, soft cock head to your lips. You breathe in the smell of him. Your tongue darts out to touch the tip to find he's already oozing. You open your lips and let his cock slowly enter your mouth.
