Cassie had asked her owner for a new set of tits a while ago. Whilst her B cups were perky, she hated that men's attention was always pulled in the direction of women with larger breasts. Her Master had agreed.
"Yes slave, your tits are too small," He paused a moment.
"You know those aren't going to be cheap though, so you are going to have to earn those upgrades". Cassie's body filled with excitement and humiliation the sound of her Masters words. She knew he would make her work hard for it but in the end it would be worth it.
"Master, i want them to be at least a Double D," Cassie Pleaded. She knew how much her would love her once she had them. After much deepthroat work, a few hundred cumshots and a few too many loads in her ass, her master came to her. "You've finally earnt those bolt on tits you asked for slave" He pat her on the head as she sat below him on the floor.
As he locked Cassie in her cage for the night, he spoke. "Slave, I've booked those upgrades in for tomorrow".
Cassie spent half the night tossing and turning in anticipation. She was finally going to have the body she had always wanted. As she dosed off, she thoughts about all the new ways her owner would use her once her new boobs had finally healed.
She must not have noticed when she did finally fall asleep because she was awoken abruptly by her master banging his keys on the cage. Like usual Cassie's owner stuck his long thick shaft through a gap in her cage. A morning ritual that provided her morning breakfast.
"Hurry up slave, the doctor is here to give you nice new tits". He spoke down to her, as if she was taking to long.
Not wanting to displease her owner and scared he would send the doctor away if she took to long she hurried her mouth onto his cock. Sure enough, after a few minutes of throat fucking herself on his shaft in desperation, he pulled out and came on the floor in front of the cage. Her breakfast was served.
