The week before the next workshop seemed to take forever to pass. I waited with nervous anticipation. When I stopped to think about it, I was amazed at how easily I had adjusted to the fact I had enjoyed being stimulated by a man. But most of the time, all I could think about was his smell, and the feeling of his finger sliding inside me.
I seemed to have suppressed any thought of the implications, or what it might mean for my identity.
More importantly, I had let go of any pretence that I was learning how to better pleasure my girlfriends. This transition in particular seemed quite liberating.
I was pursuing my own pleasure now, and I knew exactly where to look.
I arrived back at the gym the following Tuesday 10 minutes earlier than the week before, determined to get in and showered before most other participants arrived. I was surprised, though, to find the change room already nearly full, as everyone had had the same idea.
The showers were a jostle of naked bodies. The jock energy of the week before had shifted now, though. We were no longer pretending this was like any other gym shower. We had all been in that room together last week, and we knew what was to happen next.
A tension hung between us now. The comradery of men remained, but with an energy and anticipation that I'd never experienced.
The soaping of bodies seemed to play out in slow motion as we all diligently washed ourselves, erections poking out of the soapy water that ran over our muscly bodies.
One by one, we stepped out of the water, towelling off quickly, and heading out to begin the class.
I looked around to find Leo, back in the same seat as last week. He looked back at the door to the changerooms, as if waiting for me, and smiled as I approached.
"Hey man, how was the week." He asked, as if nothing out of the ordinary was happening. He sat naked on his towel, his cock already hard and beating in time with his heart rate.
"Not bad, really." I replied, trying to sound nonchalant. "Had some weird dreams though!"
He looked up at me quickly.
"Yeah, me too." He replied, a slightly quizzical look on his face.
We were interrupted by Tom, standing naked once again at the front of the room.
"Hey everyone, welcome back." He began, smiling broadly. "Good to see everyone back for the final class. Hope you all enjoyed the last one and learned lots. Quite a lot more to cover this week though, so let's get into it."
Without further small talk, he had us all up once again and on our mats in pairs. Without instruction, everyone had rejoined the same pair as the week before.
A quick Rock, Scissors, Paper run had me down on the mat first this time, wondering what direction this would take, although knowing deep down what was about to happen.
"Now," Tom began, "We can't skip past everything that we did last week, as we all want our Tails to be ready for any more advanced techniques. So, now's a good time for revision. I want you all to move fairly quickly through the massage stage, and on to the oral stimulation stage, just like I showed you."
Without hesitation, Leo dove straight into it, his hands massaging my back with a strength and quiet urgency that I hadn't noticed last time.
I settled into his touch quickly, my breath slowing down, and my muscles relaxing much faster than the week before. I found myself slipping easily into the same space as last week, relaxed in his hands. My muscles melted.
Noticing my shift, he pulled me up onto all fours and before long I felt his glorious tongue on my hole once more, licking and rimming me, saliva running down the back of my scrotum. I felt him tease my hole with his finger once again, sliding around the tight muscle, smearing his copious saliva.
His tongue moved further down, lapping and stroking my perineum as his finger tickled my hole. I jumped as I felt him against the back of my sack, lifting my balls with his tongue. His finger pressed against my hole.
Unsure how much time had passed like this, I could feel my cock straining, rock hard and dribbling fluid onto the mat beneath me. My arms seemed unable to hold me up, and my torso sank down onto the mat, thrusting my pelvis up into his face.
My shift in position caused my hole to loosen for an instant, drawing his finger inside me. I gasped at the unexpected penetration, more from surprise than pain. By reflex, my muscle clamped down on him, squeezing his finger tight as he held it just inside me.
I became suddenly aware of Tom's voice at the front of the room, even though I seemed entirely unable to look up at him. He sounded husky, soothing. Almost hypnotic.
"I can see that many of you have started to advance a little further on instinct." He observed. "Careful not to go too quickly at this point. Causing pain now would be a big step back."
Leo held his finger still inside the opening of my arse as he lapped at the back of my balls.
"For those that haven't already," Tom continued, "I want you to press a finger against your Tail's hole. Not so hard as to force yourself in, but enough so he knows you're there. Now Tails, I want you to take a deep, slow breath in, and as you exhale, push down on that finger, as if you're trying to push it out of you."
I did as he asked, even though my penetration had already begun. Exhaling slowly, I pushed down on Leo's finger, trying to force him out of me. The action caused my hole to relax, the muscle loosening around his finger. Taking the cue, Leo inched slowly inside me another centimetre or so.
Amazed at the lack of pain, I focused instead on the smooth friction, and the warmth of his skin against mine. My arse beat a pulse against his invading digit.
"Now Tails, every few breaths I want you to repeat that again. Any pain, and you should stop right there and hold it until the pain has gone completely."
As I breathed, I became more aware of the control I had over my arse. I quickly learned that I could release the muscle tension and slide back further onto his finger.
"Now Tops, there are a few differences to keep in mind here, between men and women. Stimulating your partner during penetration is a good way to make it more pleasurable for them. Remember that lots of female anatomy has some male equivalents. You can practice on your Tail now, keeping those in mind."
I was finding it hard to concentrate of what Tom was saying as Leo's finger slowly fucked in and out of my tight arse.
"For example," he continued, "stroking a woman's labia during penetration can keep them aroused and relax their muscles. You can mirror this effect by stroking or licking your Tail's scrotum.
"Clitoral stimulation is roughly equivalent to stroking an erect cock. In this situation today, I'd caution against that, since if your Tail cums, your little practice session is likely to be over. With a female partner, the more orgasms the better.
"Finally, G spot stimulation can add a whole new dimension to anal sex. In women, the G spot is located a couple of inches inside the vagina and can be easily reached with a finger during penetration.
"In men, the G spot is located in the prostate gland, which in convenient since you can reach that through the wall of his anal passage, about three inches in, if you're aiming towards his belly button. Feels a bit like a rubbery walnut."
I felt Leo push inside me once again, probing my pelvis looking for the elusive gland.
With a sudden certainty, I knew that he'd found it. A warm wave of intense pleasure shot through me as he pushed against my sensitive nerve centre. I moaned low and intense, fluid gushing from my cock as he probed me, stroking my gland again and again.
The intensity of my arousal amped up my response to his probing. The pleasure built rapidly in my pelvis as he stroked my prostate. I spread my knees further, trying to open myself up, desperate to increase this blissful sensation.
Leo responded in kind. I felt him stretch me further, a second finger venturing through my hole. His tongue lapped at my perineum, the warmth of his breath like a hot wind.
I moaned as his fingers massaged my gland, milking me, as a thick, clear fluid drizzled from the head of my straining cock.
The pleasure built quickly, an intensity I'd never felt. I moaned with the power of it, almost needing to escape it.
I writhed on the mat, but Leo followed me deftly, his stroking relentless.
With each wave of pleasure, the intensity grew. Barely had one wave receded before the next built on it, increasing second by second.
My brain grew frantic, unable to cope with the pleasure. I closed my eyes, a moaning growl escaping the back of my throat. With a sudden blissful explosion, the built-up energy seemed to escape, flooding my whole body with heat and shivering warmth.
Fluid squirted from me in a pulsing wave, splashing onto the rubber mat. My whole body trembled as the energy released. Stars flooded my vision, and a roaring filled my ears, until finally, my consciousness slowly returned.
I caught my breath slowly as my awareness of the world came back to me. Leo's fingers rested inside me, still for now. His face pressed against my arse, his own breathing a little ragged.
I could feel Tom's eyes watching me, as he addressed the class once again. His voice sounded thick. I looked up at him and caught his eye, feeling suddenly exposed as he witnessed my bliss. His erection stood proudly before him, fluid leaking slowly down the shaft of his impressive cock.
"I can see most of you experiencing the pleasures of the prostate now. Some of you even look to have had a prostate orgasm. This seems to be easier for some men to achieve than others, for reasons I don't think have been well researched. Still, once you've experienced one, you'll wonder what you've been missing out on all your life!"
I could certainly identify with that!
"And the best thing," he continued, "is that prostate orgasms are not followed with a refractory period like regular male orgasms. So you're usually good to keep chasing that high!"
