Corruption by Step Sister

The girls spent the rest of the afternoon upstairs. I guess Summer was grilling Kel to see what exactly Kel could and couldn't do when it came to her bedroom skills.

In that time I was able to get a nice cardio in the studio along with some core exercises, plus watch some more of my anime.

It was about dinner time before they came back down from their convo. I watched as Kelly still looked bo legged thanks to her intense leg workout but she had a look that I have seen before...extreme frustration. The look alone nearly made me chuckle but I was able to contain myself.

Summer followed behind Kel with a look that looked like she was disappointed and excited. But that's just my guess.

I already had made my dinner and had a grilled salmon with a loaded baked potato. A little bit of greek yogurt, some diced up veggies, and some hot sauce on the potato.

The girls looked at my meal and I saw Kel salivate looking at my meal. In anticipation I point my fork behind me, "I made extra help yourself." Both of them quickly dashed towards my extras.

I actually knew Kel ate healthy, I try to eat healthy. So I intentionally made extra because Kel always bitches at me when I cook I only cook for myself instead of everyone when we are home alone. So when I made my healthy dinner I knew she would bitch at me.

They sat down and eat all ate in relative silence.

After I finished off my meal, I decided to ask Summer, "So how's the training coming along?"

Summer put down her fork, "Well once Kel spilled the beans on her actual strengths." She looked at Kel who was turning a nice shade of red before she returned her gaze towards me, "Let's just say we have a lot of work to do."

I smiled at her, "Like what for example?"

I watched Kel turn an even brighter shade of red as Summer answered my question, "Well it appears our esteemed Kelly here has a secret she has hidden from each of her beau's."

I looked at Kel, "And what's this secret?"

Kelly's face was completely red and mumbled in answer.

I turned my head and put my hand towards my ear, "What was that?"

Kelly spoke softly and I still didn't hear it. I leaned in exaggeration, "What?"

Summer laughed and answered for Kelly, "She's a high pressure washer."

I looked at Kelly in surprise and see her face was completely red. She just kept her head down and went back to eating.

I spoke, "So what kind of pressure are we talking here?"

Kelly remained red and didn't say anything. Summer pulled out her phone and said, "Here let me show you."

Summer just smiled at me as she pulled out her phone.

I watched as Kel's eyes got wide and was about to speak but it was too late. Whatever Summer had pulled out her phone for was done and the last thing out of Kel's mouth was, "nooooooo" before it changed to "ooh god."

I blinked in confusion as to what had transpired between Summer and Kel but then I heard a light low buzzing or humming sound.

At first I thought a bee or a wasp had flown into the house but the sound was completely off like it was hiding.

I looked around focusing by heading to the task.

I looked over at Kel who was beginning to squirm in her seat and was breathing heavy.

Then I found the sound. It was originating from Kel.

As if feeling stupid my brain clicked all the signals: Kel's rapid breathing, her dilated eyes, her nipples saying hello to everyone, and lastly the low hum.

I looked at Summer, "Is she wearing..."

Right on cue Kel spoke loudly, "I can't handle this please turn it off Summer."

Summer smiled and slowly shook her head.

Kel gave Summer a dirty look but her eyes got wider as I saw in my periphery Summer do something on her phone and I heard the humming coming from Kel get louder.

Kel started moaning and started moaning breathing heavier and ripped open her shirt releasing her breasts to the world.

One of her hands started massaging her breasts and her other hand disappeared into her sweats.

After a minute Kel exploded out of her chair and got on her hands and knees starting to shake uncontrollably.

Kel looked at Summer and begged one last time, "Please don't do this."

Summer looked at Kel and said, "He needs to know."

Kel gave in and started changing positions moaning and shaking putting her ass in the air.

She turned having her ass face us and in one fluid movement she pulled down her sweats and things to reveal a small pink plastic leaf hanging out of Kel's pussy.

She moaned, "I can't take it."

And in movement she ripped the pink leash out throwing it on the floor as she groaned and screamed as her body lost all motor function.

I watched as Kel's body tensed as she sprayed a solid stream of fluid out of her pussy towards us and some of it splashed against my exposed foot.

I was transfixed at the sight finding myself completely turned on.
