Later at breakfast, when Limestone came in she acted like nothing happened, and sat down at her place like normal. For the whole meal she acted like she usually did like talking over her sisters, and she even snapped at Marble when she asked a question. It seemed like she didn't even care what Pinkie did to her earlier, but she still needed to be taught a lesson in humility.Pinkie then thought up a plan, after everyone else finished eating she told Marble and Maud not to worry about the dishes, but told Limestone to stay. Every meal so far Limestone had avoided cleaning dishes, but that would end today.

“Limey could you do me a favor?”

“What Pinkie.”

“Could you please clean the dishes?” She asked with a smile on her face.

Limestone scouled. “Why should I clean the dishes?”

“Cause I’m asking you silly, it's a nice thing to do, especially sincy you haven't washed any of your’s since you came here.” She started to scowl a bit.

Limestone chuckled “What are ya gonna do, make me?”

“Yes. Now start cleaning.” Pinkies tone changed and she started looking like she did when she was angry, Limestone felt a tingle in her pants.

“No, and you can't make me.”

Pinkie stood up and stared down at her. “If you don’t I’ll punish you like this morning.”

Limestone sat looking away from Pinkie with her arms crossed.

“Fine we'll do this the hard way.”

Pinkie pulled Limestone out of her chair, and sat down, holding Limestone in her lap, she pulled down her shorts and panties, then started spanking her. Her hand flapping against her ass with a loud clap, a mark of her hand left behind. Limestones ass jiggled from every impact, her ass starting to sting from the pain. After spanking her for a while Pinkie made her stand up, and said.

“You’ve been acting full of yourself since you came here, it’s time you learned to be a bit more humble.” She glared down at Limestone, a slight bulge forming in her skirt.

“Stip down and start cleaning those dishes, now!” Pinkie said pointing at the sink.

Limestone quickly took off her clothes, and started cleaning the dishes in the sink.

Pinkie stood behind Limestone as she worked watching her clean and making sure she did it right, Whenever Limestone wasn’t cleaning fast enough, or not doing it right, Pinkie would give her butt another solid slap. While she watched her she felt her cock getting harder from bossing her around, after a bit she started pressing her shaft against Limestones butt.

Limestone kept working when she felt Pinkies shaft start pressing into her, her pussy already wet from being bossed around. She finished cleaning the dishes and turned around to Pinkie.

“There the dishes are done, can I go yet.” She said, shifting her legs together, trying not to look at Pinkie or her cock.

Pinkie didn't want this to end yet, so she thought of something else.

“No, you haven't wash your mouth out yet, come over here and let's clean it out.” Pinkie led Limestone to the kitchen table, she sat down in a chair, but when Limestone tried to Pinkie swatted her butt, shaking her head she pointed at the floor in front of her.

Limestone could see Pinkies erection easily pushing up her skirt. She went down to her knees in front of Pinkie, she could see her cock poking out from under the skirt. She could feel the embarrassment flowing off her, it was almost as strong as the burning flame of arousal in her dripping pussy.

“Your mouth is always saying mean things, let's wash it out.” Pinkie said pulling back her skirt, exposing her cock to Limestone, it’s head glistening with pre.

“You're going to suck me off, and clean out that dirty mouth.”

Limestone was sitting stunned, her mouth hanging open. She couldn't believe that Pinkie really told her to do it, then Pinkie reached forward, grabbed her head, and pushed her cock in her mouth. Limestone could only fit a few inches in, but the smell, and taste was overwhelming. There she was, on her knees, legs splayed apart, arousal dripping on the floor, her mouth full of cock, everything was hazy with arousal. Then Pinkie said in her new commanding voice.

“Suck it.”

Limestone started wrapping her tongue around, and caressed the cock head in her mouth. Pinkie held her head there as she worked, pushing her head down slightly in short thrusts in her mouth. As she kept sucking Pinkie started pushing her cock a little further in each time she thrust, eventually pushing into her throat. With every thrust Pinkie got a little bit deeper, pushing her large cock down her sister's tight throat. Limestone started to reach down to her dripping pussy, but her hand was kicked by pinkie.

“No. This is a punishment, you're not allowed to touch yourself.” Limestone got even more horny, she started grinding her pelvis on the floor, trying desperately to get stimulation.

Pinkie started pushing her cock further down her throat, the thick shaft stretching her throat felt amazing. On and on they went, Pinkie used Limestones mouth, and throat to get herself off, thrusting her head further and further down her cock. She was being used like a sex toy, Pinkie was fucking her mouth like she would some cheap silicone hole, just so she could get off, she was just an object for Pinkie to fuck and use however she wanted. The thought almost made Limestone cum right then, but that wasn't what sent her over the edge. Instead it was when pinkie pulled her cock back till only the head was only in her mouth, and started cumming. Her whole body shook with an orgasm when the cum hit her tongue, the thought that she was cumming from Pinkie using her throat like a toy only made her cum harder. She drank Pinkies semen as fast as she could, rubbing her own pussy against the floor the whole time. When she was done there was a puddle of mare cum for her to sit in as she finished her last few twitches..

Once pinkie stopped cumming she let go of Limestones head and told her to make sure her cock head was clean, she obeyed and started sucking and licking any cum that might have gotten away. After Pinkie was clean she stood up, told Limestone to clean up the mess she made, and left the room. Pinkie didn't show it but she was scared, what if Limestone hated her now? She was just trying to make it so she was nicer to other ponies, but maybe she had gone way overboard when she got horny. She hoped that everything would work itself out throughout the day.
