"Come puppy, it's time to eat." She led him to the kitchen where she made dinner and put his in a bowl, which she put on the floor. Sanjiv looked up at her, but said nothing as he lowered his head to the bowl. She sat at the table to eat her meal, occasionally reaching down to play with the plug in his ass, prompting the periodic moan from him. She didn't rush, but she didn't take long to finish her meal. She took care of her dishes and once she saw he had finished as well she took care of his bowl. She led him to the bathroom where she removed the collar and after some reluctance the plug as well. Sanjiv by this point had given up fighting and in fact moan slightly when she removed the tail plug. He surrendered to her as she cleaned him and even did not comment when she began removing his body hair, not that he had much to begin with, but now he was perfectly smooth. Once she was certain that he was free of hair she pulled him from the tub and began drying him. Once he was dry she reattached the collar and led him back to her bedroom using the leash. Upon returning to her room she once more had him bend over the bed. Sita pulled up some straps that she had attached to the nearest legs of her bed and quickly attached the other ends to his wrists. Sita restrained him with such suddenness that it took a moment for him to react.
"What now? Sis, I think..." She smacked his ass and grabbed his balls meaningfully.
"When you speak you will say mistress or rani and you will only speak with permission." He nodded and she pulled another item from her bag. Sita slowly pulled the plug from his ass, delighting in the sounds he made, some of which sounded disappointed, Sita finished donning the strapon and lined it up with his open ass. Sanjiv tensed slightly and Sita tapped his ass.
"Relax or this will hurt, puppy." Sita pressed the head of the dildo against his ass feeling him relax as it entered. Sita moved back and forth as she slowly worked the dildo deeper into his ass with each inward thrust. Sanjiv's moaning was now almost continuous and interspersed with the occasional whimper. Sita felt her groin reach her brother's ass as the dildo sunk all the way in. Sita patted his ass softly before gripping his hips and pulling back till only the tip remained. She only gave him a moment to experience the empty feeling before swiftly plunging all the way in. The breath escaped him in a quick gasp.
Sita quickly got into a rhythm fucking her brother in fast regular thrusts. His moaning only seemed to get louder and she smiled at the marks she was leaving by gripping his ass. Sita felt as her orgasm was approaching as well, the combination of the power she held over him and the taboo of doing this to a man, especially her brother, was driving her over the edge. Sita notice that his ass was suddenly gripping her fake cock tighter and she idly wondered if he had actually cum from being fucked when her own orgasm hit and she struggled to stay on her feet. Finally she couldn't hold on any longer and collapsed onto his back, where she lay panting for several moments. Sita soon recovered and slowly stood up as she carefully eased the dildo out of his ass. This action prompted little reaction from him beyond a low moan. As she looked down to extract the dildo she saw something on the floor and quickly determined that it was his cum. She smiled as a wicked idea occurred to her. Sita patted his ass as she removed the straps from his wrists.
"Up puppy." Sanjiv moved slowly as he attempted to work the stiffness from his muscles. Once he was standing she pointed to the mess on the floor. "Clean it up, boy." He looked around momentarily before she shook her head and grabbed his chin until they made eye conduct. "Your tongue." His eyes went wide, but he merely nodded as he sank to his knees and lowered his head to the patch of cum. Sita tried to maintain a blank expression as she didn't want him to see how shocked she was that he actually complied with this order. Truthfully she would have probably not pushed it if he had refused. As it was she felt it to be a great turn on, had she not been so worn out she would told him to do something about it. So deciding to go to bed Sita gestured for him to once again bend over the bed where she reinserted the tail plug, eliciting a soft whimper from Sanjiv.
"For being such a good boy, you can sleep at the foot of my bed." He climbed onto the bed and she handed him a blanked. Sita left to get ready for bed. When she returned she found him curled up under the blanked with the tail poking out from underneath. Sita smiled and carefully got into bed herself as she didn't want to wake him. Sita settled under the covers, tired and a bit sore, but thoroughly satisfied.
When Sita awoke the next morning she was eager to play more with her pet. Sita looked down to see Sanjiv still sleeping with his tail still poking out from under the blanket. She went to take a shower before returning to gently wake him.
"Up puppy. I want to take you again." Sanjiv awoke and slowly sat up before making to slide off the bed, but she stopped him.
"No, lay back I want to try a different position." He looked at her questioningly, but did not object. She joined him on the bed and removed the plug from his ass. Sita inserted the dildo replacing the plug. The dildo slid in easily and he groaned softly. She was soon thrusting with speed and watching fascinated as it seemed that with each thrust his cock would harden. Soon however his cock was fully erect and dripping pre-cum. Sita momentarily stopped fucking her brother to grab his cock and begin stroking him in time to her thrusts. Sita couldn't believe how much pre-cum was oozing from the head of his cock, so much so that it was lubricating the strokes of her handjob.
The low moans he was making had her pussy quite wet and the stimulation of the strapon soon had her on the verge of orgasm. Soon Sita could feel his cock tighten along with his ass and noted a sharp increase in his breathing. Sita continued to pound his ass until his orgasm hit and she angled his cock so that he came on his chest. The sight of his cum splattered over his chest was enough to send her over the edge. Sita felt the orgasm hit and she felt a shuddering through her body as she experienced the aftermath. Her breathing returned to normal and she eased herself into a sitting position. Sita ran a finger through the mess on his chest and put it to her mouth smiling.
"Clean yourself up, boy." Sanjiv moved sluggishly, but he did not hesitate to scoop up the cum from his chest into his mouth, although he made a face he normally reserved for when he was being forced to eat something he didn't like. The look on his face prompted Sita to laugh as she removed the strapon setting it aside. She lay down next to her brother lounging as he breathed softly.
"So, what do you want? Is this only going to be a one-time thing?" He hesitated, but she could tell he had already decided.
"Please, can I keep being your puppy, sis..." He stopped when he saw the look on her face "...mistress?" She smiled as she sat up to lean against the headboard. She patted his head softly as she spoke.
"Of course, but I may have other pets, will you be jealous?" He didn't answer right away, but he inhaled slowly when he did.
"No, I promise to not be jealous, but please promise not to ignore me." She grinned as she idly stroked him.
"Be a good boy and I will never ignore you. Now get up. We need to be ready when mom and dad get home." He nodded and they went to clean up, separately as they didn't want to get caught.
