38. Step sibling -R18

I needed a different position. But in the shower my positions were very limited.

Sure someone could argue that you're brave any position is available in the shower.

My counter argument is sure if don't mind having a high risk of eating shit and an equal high risk of hurting oneself or breaking something.

I set down Kel she looked at me kind of confused that I didn't want to continue but when I turned her around picked her up. I folded her in half or she got the idea I had and put her ankles on my shoulder's and wrapped her arms around my neck.

The only thing I held was her ass in my hands. I used my free hand and guided my dick into Kel's special opening.

Once I felt her opening I lowered her down.

Kel groaned and started lightly shaking as she felt each inch slowly pass into her canal.

I lifted and let her fall down hard onto my dick in which I received a Yelp from Kel.

I continued lifting and letting her fall hard onto my dick letting gravity do all the work of driving my favorite appendage into Kel's delectable wet slash.

Kel started shaking more and more with each slap down onto her new pleasure toy.

It wasn't long before Kel was begging me to pull out.

Nope.

I kept lifting and letting go.

We quickly found our stride.

Kel's pussy started vibrating and convulsing on my dick s as each orgasm washed, get it washed on where we were, through her body.

Eventually her squirting orgasm slammed through her body and I felt multitudes of sensations inside Kel.

I ignored them I kept pounded.....I was close.

Kel felt my dick become more solid.

Her eyes got wide as to what was about to happen.

We both looked at each other as time stood still.

Kel was at war. She had already broken the supposed cardinal rule.....Thou shall not fuck thy step sibling.

She was about to accept that she was about to be seeded by her step brother.

I didn't have a choice.

Actually that's a lie. I have a choice. And that choice is stop or pull out.

But in this position it was difficult to undo what was about to happen.

I felt my ball sack tighten as my balls began to bounce as they were ready to fire their stored up fluid.

My dick hardened as my veins popped out.

The war inside Kel was over as she moaned, "Fill me up!!!"

I couldn't hold out any longer as my orgasm slammed into my body.

I watched Kel's eyes widen more as she felt the first splash of hot spunk inside her causing her eyes to roll in the back of head before my eyes rolled as each of our orgasms rocked our bodies.

The last thing I heard before my body went rigid was Kel groaning a Yes that was lodged and stuck in her throat as her body convulsed.

***

I left the shower leaving the convulsing Kel in the shower with my special fluid leaking out of my step sister.

I still can't believe in less than 24 hrs I had gone from concerned about my step sister's guy problem to finding out her exact problem to helping in training her through Summer's unique training sessions. Then helping her realize that hiding her special ability is what was holding her back. Then I fucking my step sister to just now cumming inside my step sister and in doing so probably birthed a converted cumivore.

If someone told me the path I just took I would have called them crazy.....and possibly caused them bodily harm.

Now I, and Kel as well, had broken so many taboos it isn't funny.

I walked into my room to find the snoring Summer. Guess I fucked her stupid last night that she needed the extra sleep to recover.

I smiled and thought that was her own fault for making me take so many supplements.

I looked down at my dick feeling the majority of the supplements were on their tail end.

I decided that possibly continuing to take more supplements might actually damage me.....or it could help with both these girl's sexual appetites.

My choice was made.

I laid out all the supplements and took each in succession.

I put on a resemblance of clothing just in case we were rudely interrupted by someone.

I knew my parents might come home tomorrow. The day after at the latest.
