Part 9

With a big grin on her face, Mary leaned forward and planted a kiss on my balls.

“Oh my! These really are a lovely blue, I bet they ache nicely”

“That’s what I like to see, a lovely pair of aching balls” Sue replied, “I always wanted a male doll when I was younger so I could have fun sticking pins in it but they never did make one, and now I have the real thing which is far better.”

I shuddered at the thought of Sue with a packet of pins and what agony she would cause with them.

“What a great idea, Sue, I’ll raid mum’s sewing basket, she has lots of lovely pins all with different coloured heads, we could get quite artistic with them.” “I’m getting really wet just thinking about it.”

So saying, Mary straddled me and parting her fanny lips got my cock in the grove, and started sliding up and down on it.

“This is nice, Sue, but I much prefer it up inside me.”

Rising up she pulled my cock vertical and slowly lowered herself down onto me. It had to be worth all the pain for the feelings I got when she did that, there could be no better feeling in the world.

As Mary started to fuck me, Sue knelt to her side and took a nipple in her mouth. Mary’s mouth opened and a look of intense pleasure came over her. Sue then put a finger into my mouth and swirled it around to get it wet. The finger slowly slid down my body as I watched it, then as Mary was at the top of her stroke it travelled up my cock until it reached Mary’s clit. The combination of my cock and Sue’s lips and finger soon took Mary over the edge and she screamed out as she climaxed. I thought I was safe, she hadn’t made me spurt again, although it had been very close.

I should be so lucky. No sooner had Mary started to relax than Sue started to tease her clit again. With a howl, Mary started to hump up and down hard and fast, her fanny squeezing my cock in ripples the way she did when she spurted. It was too much for me and once again my cock tried to spurt only to have it forced back into me. My balls weren’t just aching, they were in agony.

Finally Mary fell forward over me exhausted.

“I swear you can almost see these balls getting bigger by the minute” Sue remarked, as she lifted them and rolled them in her hand.

You can imagine my relief when for once she didn’t squeeze them.

Having given Mary time to recover, Sue told her she needed her clit hard and wet for what she wanted to try next. Mary quickly got between Mary’s legs and started licking her. All the girl on girl action I’d been seeing came as a bit of a shock at first, especially seeing Mary happily licking away at Sue’s fanny, but at the same time if it had been possible it would have made my cock even harder than it already was. Girls were certainly different, no boy would even dream of touching another boy let alone lick them. At least that was what I thought at the time.

Sue’s clit was sticking out proudly when facing my feet she sat down on my tummy.

“Squeeze the head of his cock.” “No, lower down so it opens his pee hole.” “That’s it, now help me line it up.”

It was a really strange feeling as Sue pushed her hard little clit down inside my cock until I could feel her hairs tickling the top of my cock.

“Oh god, this is awesome,” Sue cried out.

She started to carefully move in and out while Mary held me steady for her. It wasn’t at all painful, in fact it actually started to feel good. It didn’t last long though, the tightness of my pee hole around her clit very quickly had Sue soaking me as the juices spurted out of her.

Then Sue did something totally unexpected, she leant over and kissed me hard, even using her tongue.

“Don’t ever think of leaving us” she said after she broke the kiss.

While she was kissing me, Mary had been busy untying my cock, much to my relief. She then produced some soapy water and washed the smell of sex off me.

Untying me completely, Sue took hold of my balls one last time.

“I know how big these are so don’t you even thing of making yourself spurt before we see you tomorrow”

To me they felt about twice their normal size and I just hoped my mum wouldn’t notice me walking a bit bowlegged.
