Spread your legs further Cupcake, so we can see more clearly.'

I did as I was told of course, and I could immediately feel a finger running along the hardened ridge between my balls and my very exposed hole. 'This bit gets hard, ready to carry the sperm. It actually pumps the sperm so you can physically feel it, but we'll get to that later. Darlene, would you like to feel?'

Darlene didn't need asking twice and as Ms. Stella's finger was removed from my most private place, I felt another eager finger replace it, then another finger -- Arlene's -- join it.

But they weren't just touching it, they were massaging it, stroking it, making another long string of precum leak from my engorged cock and drip slowly towards the floor, except that Darlene put a finger out, and scooped the precum into her mouth.

'And while our volunteers feel our little cupcakes perineum... Hard, isn't it?' They nodded, looking at each other in disbelief that this was actually happening. '...You might notice that his anus is contracting. It's almost as if his body is asking for something to touch it, and enter it.'

The sisters, their heads almost together, looked up from their caressing to see my hole, smooth and pink and beautiful, begging to be entered. It was all they could do to resist touching it, putting their fingers in it, putting their tongues in... but they had a feeling the time would come if they were patient. They would not go against Ms Stella. No matter how much they ached to.

Bending over in front of twenty people with two older women touching me - no, not touching,.. caressing - on the hard ridge between my legs while drops of precum leaked onto the floor - or onto the fingers of the two women - I couldn't have felt more embarrassed, but really I felt like this was my place. I was bright red from blushing by the heat felt good. I found myself wanting and needed to have my virgin ass entered. The more they talked about it the more I wanted it. I started to slouch and arch to make my cock, balls and ass more accessible.

'And while we have cupcake in this position,' said Ms. Starla, 'Now we're going to spend some time on Cupcake's anus,' said Ms. Starla, matter-of-factly, 'I just want to indicate the power of anal probing. If I could get you two sisters to pull little Cupcake's buttocks apart... My dear, do you need something to lean on?'

I nodded indicating that I did at which another woman, this one younger --- came up onto the stage with what looked like a sports bench of some sort. Positioning it in front of me, so that I could lean forward and rest on my elbows, the girl stood back to make sure she'd placed it right. I looked up but noticed she was not looking at my face but at my cock, clearly captivated by the bobbing, leaking, swollen thing. She was smiling, pushing her lips forward in a bit of a pout.

'Thank you, Dear,' said Ms. Starla, moving forward so she was level with my up-turned backside, and standing so close that I could feel her skirt on my bare flesh and the heat from her body against me.

'Now, if I could get you ladies to spread these buttocks again...'  Each of them hooked the four fingertips of one hand to the inner curve of my bottom and scooped outward, the flesh almost trembling in their grip.

'And there you have it,' said Ms. Starla, 'the anus of a sexually aroused young man. Isn't it lovely? Obviously, this has been specially shaved for us by Doreen...' A small ripple of applause broke out as people looked round at Doreen sitting proudly at the back.

'Some boys of cupcake's age will have quite a bit of hair down here so it's good to shave away just so you can see what you're dealing with and what you're doing. It's also a very good way of maintaining high hygiene levels.'

With my little pink hole, completely bare of all hair, now the centre of attention for a whole roomful of people, I realised my earlier embarrassment was just silly. My legs started to tremble with... was it fear or cold or anticipation?

'Now, when entering a young man's anus with your finger, you should use lubrication but I've always found...' and she put her own finger in her mouth and sucked it, 'that a little saliva will always do the trick if you don't have lubrication to hand. Make it nice and sticky and then...'

With my buttocks still being stretched apart, I felt the finger of Ms. Starla's approach my hole. First she stroked my hole... 'Rub a little of the saliva or the lubricant around the area...' then began to penetrate it. 'Be careful and go slowly,' she said. as I let out a heartfelt groan of pleasure.

'You see, so far I only have my finger in down to the first knuckle. A little more saliva...' And I could her  spit hit my backside, just above my anus: she was dribbling on my hole... 'and you can get in to the second knuckle. Is that alright my dear?'

I nodded.

'We can't hear you...'

'Yes, Ms Starla, That is wonderful. Thank you Ms Starla. I said.

'And now all the way...' and her middle finger slipped all the way into my tight anus. I let out another involuntary moan. 'I think we can already see the effect this is having on little Cupcake.'
