Submissive donor

My eyes widened as Paula looked up.

"Turn around and face the wall, you pervy little bitch! This is for Kate, not you. You can touch yourself and get your next donation ready for this beautiful creature!"

"Yes Mistress" I turned around and faced the wall as I heard a guttural moan from Paula. I felt my cock swell.

"Oh fuck, yes babe.... Yes. Love that pussy. Use your fingers... Oh yes. Keep going."

I heard Paula stifle the noises as she came and then Kate giggling. "You're delicious, I'm not done yet...".

"Ohhhh ohhhhhh. Just there.... Fuck you're good with your hands... Oh my god."

I was wanking fast now and I couldn't hold back as I heard Paula shout loudly.. "Oh no, no, no, no"

It was too much and I lost control shouting another huge load up the hotel room wall, I moaned but hoped that the girls were far too distracted to notice.

"Mmmm, I didn't know that you could do that! You nearly drowned me..." Kate laughed.

"I'm so, so sorry. That doesn't usually happen... It was just your fingers.i haven't cum like that in years... I think that last load should have got to where it's going now, if you want another from him?"

"You know what, I think that I've got what I came for..."

"Toby! Go and shower and go home, wait for my next booking. Oh fuck. What's that on the wall? Did you waste? You filthy little bitch. Get on your knees and lick all of that up. "

"Yes Mistress."
 
As soon as I got home my phone went.

Paula: What was that?! Don't ever waste my cum. That won't ever bairn again.

Me: Sorry Mistress.

Paula: I've got a booking for a cold donation next week and Jill wants you and Kate to come over for a girls' night soon to celebrate her success. I'll keep you posted. Keep everything shaved clean, it looks more sanitary.
 
A week later my Paula came to see me in my Anaesthetic room. No one was around and she talked quietly.

"Cold donation, tonight. Meet me in the department when you're done. I've got some special lube free condoms, I'll drive you to the address, you fill it and she wants us to post it anonymously. Tell C we've gone climbing, I'll have you home in an hour.".

"Yes Mistress".

I finished my list and Paula was already waiting for me. We walked down to her car.

"She only lives 20 minutes away. I want you to shoot as soon as and I'll drop it in for her, she wants it as fresh as possible to improve her chances. I'll just have to park up in a quiet spot nearby. You can do that right?"

"Really? We might get arrested?!"

"Don't worry, I'll keep an eye out, I'm not going to watching you, am I? You need to produce a decent volume, she's our first paying customer."

We drove just out of town into a very leafy suburb when Paula pulled in on the side of a quiet side road.

"The condoms are in the glove box. Take down your things and fill one. Now."

I opened the glove box and found some unbranded lube free condoms. I took one and undid my jeans and pulled down my boxers. I was already hard and wet.

"Get that condom on now. And don't make a mess on my seat."

I rolled the condom down and Paula watched, I was already aching before I even stroked.

"Come on, you need to be quick for fucks sake."

Paula reached over and squeezed my balls and I came immediately....

"Ohhhhh fuckkkkkkk"

"Good boy! That's a great volume too. Make sure that you're done and then kneel up so that I can milk it down. Have your pants ready. Do not drip on my seats!"

Paula did just that, tied a knot in the condom and walked just around the corner, she was back quickly.

"Easy money. We'd better get you home to your wife. We're having the girls' night on Sunday at mine, come over at 1900 and be prepared to stay, don't worry about what you're wearing, we've got plans for you."
 
Sunday night was only 4 days away. What was I going to tell my wife? Another night on call? What did Paula mean, wear what you like? Why was I going to a girls' night?! So many questions. But at least I'd got a release from my swollen balls. They still felt full but I'd eased some of the pressure and my Mistress was happy with the quantity.

I pulled up outside Paula's flat and pressed the bell. "Come on up!"

I let myself in to the sounds of giggling girls. Paula was in the kitchen mixing what looked a martini in pyjama bottoms and a vest top, Jill was on the couch (again) with a glass of prosecco in pyjamas and Kate was in a silk robe, also with a glass of bubbly in an armchair.

"Here she is!" Shouted Jill as I walked in. "Thankyou so much! I already feel myself growing... And Kate thinks that she might be too, but she can't test until next week. "

I smiled and mumbled "congratulations".

Paula came in with her martini. "We thought that you could join in the celebrations and we could give you a little make over. It can be our thing. You can get changed in the bedroom, I've put some clothes out for you on my bed. Off you trot."

Kate smiled at me as I walked into the bedroom. On the bed there were a set of Paula's lacy black knickers, a silky black camisole and black fishnet holdups. This had to be some kind of sick joke.
