Step Sister Corruption Part 181 – Day 103 Thanksgiving Pt 4 Sealed (fiction, M/F/F, d/s, teaching, step siblings, con)

*Gabe*

Summer and Kel looked at me with puppy dog eyes as they both begged for their individual releases.

Summer begged, “Please Gabe release me!”

I grabbed her chin to look up at me, “Come now where’s that intriguing mind of yours?”

She looked up at me with pleading eyes, “Please Gabe.”

I looked down at my girl as she begged and pleaded with me to release her.

Just moments ago I got both girl’s to agree to a series of experiments to see exactly what all our bodies had undergone in our individual changes.

I had gone into Kel’s room to retrieve items that would best help with the experiments I had in mind.

I grabbed the bondage tape that Kel has, which is what you would think. It’s simple tape but doesn’t have any of your normal tape’s sticky adhesive glue on it. Instead it sticks well to skin and itself very well. Plus it can used multiple times without wearing out so it’s meant to be used over and over.

I grabbed two sets of ankle and wrist leather restraints along with some rope. Then I grabbed two long bars. Some paddles. A whip. And lastly I grabbed some rubber ended nipple clamps with their own individual chain’s.

Still surprises me to see exactly how much gear Kel has each time I rifle through her *gear*. She’s one prepared closet freak.

I walked back out and was going to call the girl’s but decided against thinking they could spend time with their families.

I held up the items to my girl’s, “Ready?”

They looked at me skeptically as I held up the items.

Summer was the first to speak, “How is that supposed to help us?”

Kel looked at the items but remained silent as she blushed.

I looked at her, “You want to know what your new bodies will do right?”

Summer looked at me, “I already know what my body can do.”

I smiled, “Oh really?”

I walked up and lightly pinched her nipple causing her to moan out and nearly drop to the ground.

I waited for her to regain her composure, “Because I don’t remember your nipple being that sensitive before.”

She looked up at me and growled.

I smiled holding up the items, “So you want to test it or not?”

Summer sighed and looked at Kel. Kel for her part looked between us and smiled, “I trust you Gabe.”

Summer sighed but looked at me, “Yeah fine.”

I pulled out the tape and cut a piece of the material and *helped* place the strip along their pussies effectively sealing their pussies.

Summer growled, “How is sealing our pussy’s meant to help us Gabe?”

I smiled as I applied the tape to Summer, “This will help show how wet you can get.”

She looked down at me, “But we already know I can get wet.”

I looked at her, “Really? How long do you think this tape will stay on then?”

Summer blushed before she answered, “A couple of days.”

The point of the tape is when it’s applied to skin it sticks only getting more strong when it’s applied to itself, say like if it’s wrapped around skin and itself around say a chair or something effectively bounding you to the furniture. The wetter your skin gets the stronger it becomes.

However if it’s applied to skin alone and nothing is helping it stay in place the wetter your skin gets the more likely it’ll fall off.

So if you were to apply the tape to seal off a piece of the body that gets wet, say like a pussy, the more likely it’ll just fall off when the wet to skin ratio is too high.

With that in mind, though this *tape* would effectively *seal* the girl’s from any penetration. The more their pussy’s juice up and leak said juices all over the tape the less likely the tape is going to keep them *sealed*.

However on the other side if the girl’s were to remain dry, or not leaking, and they kept their hair shaved the tape could potentially remain in place for however long it is kept there.

I lightly thought of making the girl’s keep the tape on sealing their pussy’s in what could be considered a girl’s version of *No Nut November*. So they can’t masturbate or have sex for however long I tell them to keep the tape on.

But seeing how one of Kel’s income is her masturbating in front of lonely losers willing to *donate* money to her kind of defeats that purpose of her *sealing* her pussy for my greedy *tests*. Besides I highly doubt many guy’s would willingly *donate* to a girl if they can’t see her in her full glory or not as much.

So keeping Kel in a *sealed* state wasn’t exactly productive.

Now keeping Summer in *sealed* state was more likely and would probably produce more reliable results.

Then again *if* I did that there was **high** chance Summer would pay me back for putting her on the *no sex, no masturbation* for science path.

And I highly doubt she’ll take the *C’mon baby it’s for science* explanation very well.

My memory of my blue balls incident flashed into my mind and thinking that would be very mild if I were to tell Summer she wasn’t allowed sex or masturbation until the tape fell off.

I shuddered at the memory.

I looked up at her getting back on track, “And how long do you think this tape will hold on your new body?”

She sighed, “I have no idea.”

I smiled, “That’s why we need to test it.”

She grumbled, “Fine.”

So with them *sealed* I placed the cuffs on each girl and had them spread their legs to accommodate the bar forcing them to stand with their legs spread apart. Then I cuffed their hands behind their back and used the rope to keep their hands tied.

Before I began my *tests* on the girls to see how quickly the tape would keep them *sealed*. Summer was the first to ask, “So what tests are you going to do on yourself?”

Kel liked at me, “Yeah if we’re testing our new bodies with this stupid tape. What are you going to do to test yourself?”

I smiled, “I have the most hardest test of all.”

Summer looked at me quizzically, “How so?”

I looked at her, “I get to hold back while I help test you.”

She looked at me, “I don’t think that’s too hard.”

Kel laughed at the joke.

I shrugged, “Eh to each their own trials.” As I hooked up the first clamp to Summer’s nipple causing her to Yelp and moan.

I didn’t give her a chance to adjust as the other clamp clamped down on her other nipple.

Then I moved over to Kel and repeated the process.

After both girl’s had their nipples stimulated, I pulled out my dick and started teasing both myself and them.

I did things like waved my dick in their face and teased them saying shit like *is this what you’re craving?* or *you know you want it*.

All while lightly tugging on the chains to their nipple clamps.

If the clamps slipped off, I simply reapplied them and repeated my process.

Granted in the beginning I got answers like *Yes*, *Don’t do this* or *Please Gabe let me have it*.

Summer more than once growled *I’m going to make you pay for this!*.

But her attitude changed when I put my mouth on their nipples which riled them up.

Then I cheated as I pushed on the tape right where their clit was.

Yes, I’m an asshole.

But I’m a caring asshole willing to help them with their *issues*.

Soon their defiant attitudes, mainly Summer’s, quickly disappeared as their bodies made them want sex badly enough to where I noticed when I played with their clits against the tape moved freely with the little jiggle I did.

And that’s where we are now…..them pleading begging for me to untie them and fuck them.

I wanted to oblige but we needed to know the full limitations on our new bodies.

I was about to give in as my own *need* was strong but had to keep reminding myself this is for them.

I looked at the girl’s as I held up a paddle and smiled, “You two ready to test your bodies?”

Summer visibly gulped and Kel both blushed and lost color in her face.
