I buttoned a fresh bibbed apron of crisply starched cotton-silk mix to the front of my nursing dress, pulled the wide waist ribbons behind my back and fastened them into a bow. My cap was neat and straight in the middle of my hair, slightly forward of my crown, just like the pouffes liked it to make me seem stronger and totally superior to them in their de-maled and amply weakened condition. The mid-blue nylon of my dress cupped my curves very effectively while hugging my legs to below my knees. I was ready for their third milking session of the morning.

I rang the summoning bell with three long rings then three short rings - the signal for sissy-wanking - and sat on my chair with my basket of fresh women's and girls' panties, waiting for the eager click-clack of sissy heels. They were not long in coming and the three sissies of girl group D were all with me in just a few seconds. Their perfumes and hair sprays filled my nostrils, while the rush and sizzle of their dresses filled the whole room.

"Stand in line as you should, sissies," I insisted, sitting watching them, fully aware that the first sissy would now be having his fourth wank of the day since he had had an early double wank-off before the mid-morning cumming. "Now, remind yourselves how sweetly you are dressed for your girly sexual spending as sissy-girls by Nurse Tightskirt. Prepare yourselves first of all by checking and adjusting your dress. Brandie, you look like you are truly a girl in your lovely peach pink spotted dress. Lovely, sissy-girl. Now your make-up mirrors, all three of you. Are your eyes looking sweetly girly? And your lips, do they need more shaping. If you are happy that you are deeply feminine and pretty you may put away your purses. Check your lingerie, your suspenders, your stocking-tops. Now, fluff out your petticoats and dresses. Good girl, Plaid, frill out the back of your lovely pink dress, now the left side, now the right side, and now the front over your pretty petticoats for me. How darling you look, Sweetie, you must be feeling so like a girl in your heart. So pretty and so feminine. Is your feminine little dickie feeling ready to be wanked by Nurse Tightskirt in a few moments, darling?"

Plaid Cupcake shrank into a sissy stoop beneath his little white girls' panama hat. "Yeth Nurthe, I feel tho pwetty, an' yeth I'm a luvverly lickel girlie, all weady for my thithy wanky-wankieth." His cock was already quite upright under his petticoats: I could see its shape in the skirt of his rose pink dress.

Then I turned my attention to James Wimping who was standing closest to me, holding the sides of his mauve silk and organza dress in the fingers of his matching silk opera gloves. His fashionable perfume would have been too fragrant for most girls, unless it was a day on which they were going to be surrounded by horny guys and wanted to knock them all out.

"James Wimping, haven't you squirted out enough of your cream to last until this afternoon? I'm surprised you answered the wanking bell."

He was a pretty boy, and I had him in an exceptionally large hair ribbon today which made him look truly wimpy as his head bowed in a state of sissy confession. His white nylons sizzled as he squeezed his knees together in shy confusion. "But Nurse Tightness, it's my panties: they're so girly and they make my coquelette feel so pretty. I'm sure it's feminine already, but - Oh please, Nurse, please make it truly feminine with lots more wanking and fondling. Pleeeease!"

I gave him the 'strict but maybe I'll give in' mother's look. He was desperate for panty milking and I reached for his hips and drew him next to my skirt. "This dick is rigid," I said, holding him round the back of his panties while I used my fingers to feel the full shape of his cock in the pink silk. "This shaft is too big to be girly, even though I am sure it feels like it must be a girl's clitoris."

The squirms of his body rustled through his whole dress and his arms, bent at the elbows, spread outwards with limp wrists, wanting to hold his Nurse but knowing that a sissy can't do that. "Oh it is, Nurse Tightskirt, it is a girl's clitoris. I want you to make it much, much more girly by playing with it in its lovely panties - until it shows how girly I want to be in them."

"Yes, well," I hummed. "Tell me, Miss James, while I am feeling your panties like this - why was your dicky given a double wank-off this morning? You must have done something to deserve that."

The sissy gasped for breath as my fingers shaped and smoothed his panty contour while he did his best to answer my question. Sissy Brandie and Sissy Plaid stood open-mouthed, holding out their dresses to the sides, shifting their weight from one high heel to the other as their knees rocked and slid together with sensual emotion as they watched and listened.

"It was Nurse High-Heels and Nurse Petticoat, Nurse. While they were bathing us in the nude this morning in perfumed soapy suds, they arranged our botties all close together, with our knees in the air and our dickies facing each other so that they could compare our sissy dickies with each other." He hung his head in shame as he confessed what happened. They decided it was - ohhh, it was MY little coquelette that was the smallest."

I knew about this of course but I feigned surprise.

"It wasn't just the smallest," cried out Brandie, "it was the sweetest too: softly wrinkled and almost cuddling inside itself - on top of his dainty little testicles."

James gasped and wriggled in my hands at this revelation.

"And both nurtheth agweed," added Plaid, "hith lickel dickie wath definitely feminine. Tho it had to be dwethed in pantieth ath thoon ath it wath dwy."

This story of what had happened at bath time was having a striking effect on James' cock right now, in my fingers. So much so that I turned him to face the other two and drew him down onto my skirt, the better to bring his sissy dickie into full pantied display for his sister sissies.

"Our nurses held James across the laps of their aprons," went on Brandie, "and dressed him in a really pretty girls' bra with lovely lace over the cups."

"Then they had the matching pantieth - girlth' pantieth. They uthed to belong to a girl called Thamantha Goldilockth and they had lathe up either thide of the guthet - "

"Yes," said Brandie again: "the lace was ever so pretty, up either side of where his dickie was getting stiffer and thicker all the time as they fondled it for him."

My own fingers were playing the length of his cock the way his nurses must have done a couple of hours earlier, so that the boy slid down deeper into the well of my apron, opening out his petticoats and dress to reveal the full shape of his panties and his stocking tops.

"And what did Nurse High Heels say? And Nurse Petticoat?" I asked them.

"They thaid: 'Who'th a girly girl wiv a darling lickel peenie?' " cried Plaid, squirming with pleasure himself as he watched the struggle James was making to avoid submitting to my fingers as I wanked the full length of his cock. The sissy was sliding his bottom from one side to the other with my hands following his every move, bringing him closer and closer to the total wank I wanted to inflict on him.

"They told him he would be a girl by the time they had drawn his sissy cream out of his flowery little bit, and his legs opened out wide when they said it."

"He wanted to be a girl for them," cried Plaid, and as he said it, James spread his knees wider and wider for me, so that he was practically lying flat on his back with his hair ribbon under my chin while my fingers drew up and up and up the length of his rock hard dick.

"Yes, Nurse Tightskirt," he whimpered, his fingers trying to stop me, or were they wanting to help me to fondle his most sensitive feminine parts for him? "I want to be your girly girl. I want you to play with my lovely girly dickie." He moaned and warbled in a string of whimpers as I lifted the soft silk of his panty over his knob to reveal the full thickness of his aching cock, and slipped the panty waist elastic lower and lower to reveal to the other two how hard and long, but how feminine his cock was feeling for my fingers.

"Oh isn't it a sweetie," I cooed, feeling his shaft and its helmet in every detail with the tips of all my fingers. It was approaching its climax because of the revelations told by his two companions from their morning bath time. I saw them watching it with avid attention, waiting with longing for it to react in a truly sissy style. First Brandie, then Plaid, lifted the fronts of their dresses and uncovered their own panties, and unsurprisingly they were both as stiff as the squirming, moaning sissy on my own lap.

"This very sweet dickie," I said, feeling it start to throb, "is going to prove itself to be a girl's clitoris," and I hugged my arms closer around him in his dress and petticoats. He groaned all the louder, almost squeaking with his desire to surrender. "It wants to be a girl, Sissyikins. It wants to feel feminine and give out its girly juices. Shall we do that, in big, long, feminine squirts? - that's it, Sissy James - like that - and again, feeling so effeminate, so sissy and so sweet as you shoot out your girly creamies."

It wasn't just James who fired his spurts of jism into the air through my fingers. Brandie's jism appeared at the very point of his panties and sent a dribble of pleasure down his gusset, while Plaid spurted too into his silky panties, with dribbles of cum wetting them down the front and pushing it through in a hanging string of cum as he spent and spent his girly desires at seeing what a girl his sister sissy was becoming.

I could only wait until their desires had satisfied themselves, then gather their panties and wipe clean all those feminine little dicks. Then I would have to dress them all again in the prettiest of wanking panties and start again, this time with Sissy Brandie on my knee.
