She heard the one word she wanted more than anything else. "Yes." With that she let go of every restraint. She moaned and screamed. Her whole body shook from the intensity. She couldn't focus on moving her body though his dick never stopped ramming her ass. She convulsed and felt her stomach churn as her muscles rippled. It went on forever. She had no idea how long. Wave after wave. Even as it threatened to stop, he would move an inch and it would start again.
She pushed back against him and then he pulled her torso up into a mostly vertical stance on her knees. She reached back an wrapped an arm around his head and tried to kiss him but couldn't quite reach. He used his left arm around her belly to support her and started massaging and playing with her breast. That set off another wave of orgasm and her pussy and ass spasmed and quivered.
When she thought it would finally stop, he came down with his right hand and started lightly slapping her clit repeatedly. "Oh fuck!" she screamed out loud. More shaking from her body to the point that she would have fallen off the bed but for his firm grasp around her belly. At that moment, Mr. Michaels let go in her ass and she felt hot cum spray into her colon. She clung to his neck with her arm for dear life. The strongest orgasm of her life hit at that moment from the slaps on her clit and she squirted a week's worth of denied orgasms out of her pussy. She had sticky liquid all over her legs.
Eventually the shaking slowed but didn't stop. He laid her down with his dick still in her ass and they rolled to the side in a connected spoon. Both panted from the exertion. She felt his dick recede and then slowly drop out of her ass. Her asshole felt a foot wide at that point and she felt his seed seep out of it. They laid there for quite a while. He continued to trace over her skin in a light touch along her arms and belly.
"That was unbelievable," she finally let out. She turned backward to look at him as much as she could and said, "I think I like anal sex!" They both laughed.
After a decent rest, he sent her to the bathroom to get cleaned up and to bring a warm soapy washcloth and towel back to clean him up. She ran off to the bathroom with her hand over her butthole as his cum continued to squish out of her with each step. She couldn't believe the complete sense of relieve her body felt from getting to let go. It had been mind-altering, and she kept reminding herself that it had only been a few weeks since all of this had started. She couldn't believe how far she had come.
She cleaned up and once satisfied that she had finished leaking, she got the washcloth and towel. She warmed the water to make sure she followed the instructions perfectly. When she came back, she started on him and carefully washed his cock and balls first and then any other sticky spots from her gush. Embarrassment by how much had come out of her made her blush. She also tried to clean up the sheet as best she could, but it would definitely have to go in the laundry later. With everything returned to the bathroom, she stood at the bed with her hands behind her and waited for him to tell her what to do.
He seemed to be considering for a few minutes. Then he got up and told her to get back on the bed on hands and knees again. He brought out several lengths of rope. Using the d-rings on the cuffs, he linked each wrist to its corresponding ankle. That forced her into a downward dog position with her ass up in the air and her head positioned right on the wet spot she had left on the sheet. Then he tied each ankle with rope to either end of the foot board, making it impossible for her to pull her knees together or really to move her legs or arms at all. He had her good and trapped.
He stuck the next size up plug into her ass. She noted that it slid in with relative ease. Despite being a bigger size, it popped into her ass as it cleared her sphincter, but it didn't hurt. His dick had stretched her ass out without a doubt. This time he twisted her hair into a pony used the rope to tie it. He folded her hair back over the tie and then looped the rope around it again. Testing it, he pulled on her hair with the rope. It didn't really hurt, but it controlled her head completely. As she expected the other end of the rope went through the handle of the butt plug and pulled tight enough that her head got pulled backward. Tolerable, but uncomfortable. It also meant she couldn't see anything he did.
She heard him get something out of his bag of tricks and heard him plugging it into the wall socket. She got nervous while he got in position behind her and she felt something press against her pussy. It felt like a large ball, like maybe a baseball, but cold and plastic. "This is a hitachi. It is a more powerful vibrator. Same rules apply. Don't let that plug come out of your ass and don't forget to beg for permission to cum." As if to emphasize his point, he paddled her ass twice. Surprised, her natural reaction forced her to pull her head forward and she felt the plug pull right out of her ass.
"Already off to a bad start I see. Do I need a bigger plug slut?! Or are you just too lazy to follow orders?" His questions seethed with surprising anger.
