Delivery and a new twist

On the third day, Sarah again woke him and demanded he pleasured her with his mouth. This time she said "I love how good you are getting with your mouth daddy. It's not as good as your dick but maybe some more practice and you will get there." She mused after having a huge orgasm and laying next to Tom cuddling. Tom was starting to feel more and more of the effect of constantly being aroused and not getting any release. They kissed and the only thing he could think of saying was "Yes Princess".

Sarah spent the morning work hard in the workshop but at noon there was a ring at the door. Sarah called out "I'll get it" thundering down the stair to get the door. Tom looked through the window and saw that it was a delivery truck. The driver returned a couple of times to get things. Sarah went up and downstairs a couple of times before she was done. During dinner Tom brought up the subject "You got a lot of packages today." he said as nonchalantly as possible. "Yeah, I wanted to be prepared for when Diana gets here." She said trying to hide her excitement. "Like what?" Tom tried to probe. "Oh, mostly cosplay stuff but I got us something for tonight." She hinted giving one of her mischievous smiles. Tom felt a flutter in his stomach and a tingle in his cock.

Later that evening when Tom came up to his room Sarah with a box on her lap reading an instruction booklet. "What are you reading Princess?" he questioned. "Oh, you know that because of your punishment you can't fuck me with your dick without ruining the whole exercise. So for the time being I will have to make do with the next best thing, a copy of your dick" Tom didn't really understand what she meant but when she pulled out the object from the box he understood. It was a "clone a willy" kit. Tom was kind of relieved that his princess wanted his dick and not some other dildo to masturbate with. He was also secretly happy at the other thing she said about maybe fucking at a later state. "Yes Princess, what should I do? he said standing in front of her. "Nothing," she said before getting out the key and freeing his dick, and after a short while with Sarah fixing with the tube the "willy" was done. It was an exact copy of his dick. He was again locked up. "Are we done for the night princess?" he asked.

"Oh no, we are just getting started," she exclaimed pulling out a harness from the box and slid the dildo into it. Tom recoiled first think that she was about to fuck him with his own dick but she gave the harness to him and said." Tonight you get to fuck me. He downed the harness and Sarah produced some lube. He fucked her for he didn't know for how long. She came several times while he tried in vain to push through the frustration but only making it worse. Finally, he was exhausted and fell next to Sarah on the bed. She was drenched in sweat from both him and her. She hugged him and gave him a kiss stating. " Thank you daddy for an amazing fuck. I love you so much." Tom smile and said "Anything for my little princess". "Can you carry me to my room? I don't think I can walk right now," she murmured into his shoulder. He carried her to her bed and tucked her in. He kissed her on the forehead. "Sleep well my princess," said returning to his room to gather up her thing and left them just inside her door. Tom was more and more under Sarahs' spell. He hadn't even noticed the key to his chastity in the box of things he left at her door.
