Chapter 7: A Useful Boy

The action in the stable had left us both hot, sweaty and in need of the bathroom.

Iris led me to her bedroom en-suite and we eagerly striped off.

After a slippery soapy shower together, we towelled each other dry.

From her bedside cabinet she poured us both a stiff bourbon which we sipped as we fondled.

My small breast felt especially firm and sweet; the nipples red and erect.

I felt confident and attractive and sexy; almost an equal to Iris whom I now adored.

Sprinkling talcum powder on each other, we ground our hips together; our snatch juices flowing.

We kissed; our bourbon flavoured tongues entwining; I wanted her badly now.

Then snuggled into her bed we cuddled closely.

She began conspiring with me over handling Ben’s next sex session with me.

She fingered my clitoris while she skimmed over the delights in store,

“Ben will be serving you well in the bedroom soon ... you’ll be making a man of him ... with an extra big penis he’ll be so proud of ... building up his sexual staying power ... strengthening the love for his mother ... handled well, he’ll become ... a great little stud Margo.”

Her ideas made my mind dizzy with lust.

Iris then got out of bed and went to her wardrobe. She was busy with something.

Then she came and stood by me. Her hardened nipples peeked through a studded black-leather halter.

Strapped around her hips was something I’d never seen before.

She was wearing a large shiny black dildo!

My heart thumped in both terror and excitement.

But I also saw her hand held a black leather strap and in a trice she had my arm in a lock from which I could not move.

“No Iris please don’t...” I began.

But pulling away the duvet she positioned me laid face down, my rear-end up.

“Right my girl. I’m giving you a short flogging before I fuck you.

It helps me get in the mood. She chuckled.

I groaned, yet my cunt was wet with anticipation.

Then over her shoulder she called to someone,

“OK Ben you can come in now.”

Horrified I looked up to see my son step into the room; ready to watch!

“No Ben!” I shrieked.

Ben glanced at me with guilt but it was gone from my mind that instant.

The pain came as a shock.

THWACK!!

First the sound of it smacking into my flesh; then the intense stinging pain.

I shrieked with shock.

Then came the next stroke; and the next; ever nearer my vagina.

I was sobbing fitfully now as Iris spat out spiteful curses on me.

Then it suddenly cease as she moved to straddled my ass.

One hand grabbed my hair while her fingers prepared my cunt for the dildo.

Within a trice she had humped it’s full length into me.

It felt gross and intrusive inside me.

I lifted my face and again caught a glimpse of Ben.

He was masturbating as he watched!!

I felt a wave of humiliation wash over me.

How had this happened?

Iris began to ride me with tantalising motion that was clipping my clitoris.

The initial pain turned into pleasure; I began sweating with sexual excitement.

I was ready to climax but Iris had other ideas.

She withdrew the dildo from my snatch and I cried out in frustration.

I felt helpless and emotionally stranded.

“Please!” I begged.”

Iris smirk at me and turned to my son.

“Ready to make yourself useful Ben!” she snapped.

Grabbing my hair as a bridle she remounted; riding me hard to release my climax.

Just as I did so my head was wrenched to face Ben’s cock.

He forced it into my mouth; grunting while he shot his load.

Shamefully I had to swallow.

Iris stroked Ben’s head lovingly.

“Good Boy!” she soothed.
