The sperm donor

[chokewave]

I wrote this story a couple of years ago when one of my friends was working in a fertility clinic & she told me so many funny stories about the guys who came in very sheepishly to give samples. In real life, in these clinics, there are only a couple of Playboy type mags to "help the guys along" but in my fantasy with Alan I was, shall we say, a more active participant. Enjoy!

Alan took the cup he was given by the receptionist and walked into the clinic room. It was comfy, with a chair, a TV on a stand & an examination table. But what he didn't expect was a nurse (me!) waiting in the room. As he walked in I closed the door.

"Welcome." I said, with a brilliant smile. I looked good, even if I say so myself. I wore a very short skirted white one piece nurse uniform, black stockings and black high heels, every guys fantasy nurse. The uniform was a size or two too small and I was busting out of it.

"Thanks, er, what are you doing here?" It wasn't a bad thing that I was there, it was just strange. He always thought that infertility clinics left men to get it off themselves.

"I’m here to measure your penis, a measurement we take for study purposes, and of course to assist you in any way you need." I said this while pulling a measuring tape between my hands. This was going to be interesting. His cock was already pushing against his underpants, just looking at me and thinking about my fingers so close to him.

"OK, I'll let you measure, but all the assistance I really need is for you to stand there and look as sexy as you do, I can do the rest." I smiled at him and approached as he took his trousers off and underpants down. He stood at attention & stroked himself a couple times to get more blood into his cock. I licked my lips as I bent over, legs staying straight, deliberately sticking my bottom out, and my fingers lightly poking him as I measured his length.

"Five and a half inches, very impressive." I stood up again, put the tape over his head and around his neck with a grin, and then walked off to a counter where I had pen and paper.

"I'm sure you've seen bigger." He was still stroking as he watched me walk away, my hips swaying.

"Well, yes I've seen bigger, but they've all been rather ugly. You, on the other hand, are the longest I've seen that I've wanted to fuck." I said this while writing down some information. He was surprised, and his cock pulsed in his hand in response to my comment. He moaned a little, and started stroking harder. I put the pen down and walked back over. I pulled on my dress, which had snap buttons down the front from my neck to the bottom of the dress. The dress came off easily and fell to the floor. He licked his lips, still stroking harder and I smiled as my hands rubbed up and down my body. I had on a black lace matching thong and bra, and a black suspender belt to hold up my stockings, and I twirled to show him.

"Bloody hell, this is better than I thought it would be." He stroked harder, and grabbed the cup with his other hand, feeling his cum build.

"Oh, you have no idea..." I tried to say seductively, as I knelt down in front of him and took over. I pulled his hand away, and grabbed his cock, stroking just as fast and vigorously as he did, and wrapped my lips around the head. He held the cup next to my head, waiting to catch his cum. He was getting close.

"I need to collect this.." I looked up at him, still tossing him, still sucking, pulling his cock further into my mouth. "Hey, what about collecting the sample?" He was about to release, and still I kept on, sucking hard, wanting every inch of him. Both my hands grabbed his bottom and I pumped him in and out of her mouth, my lips wrapped around his hardness.

"HMmmmm.... Unnnngggg......" He started to gurgle as he came into my mouth and his body convulsed. I kept milking him, sucking every last drop. I finally let go, and he saw me swallow.

"Ooops..." I said with an innocent smile and rose to my feet. He leaned back against the examination table. "You can't leave here without giving us a sample, looks like I'm going to have to help you cum again." I pulled his shirt off and pushed him down onto the table. I then pulled his shoes off and removed the rest of his clothes. I pulled my thong down to reveal my very engorged shaved lips. His cock pulsed back to life.

"That's a good boy." I climbed up and straddled his hips, still wearing stockings, high heels and a bra. I pulled the shoulder straps down to let loose my breasts and he curled up to lick and nibble them. I moaned and closed my eyes, my hands massaging his cock and guiding it into my dripping hole. He gasped as he entered me, blowing hot air onto my nipple - I giggled. Soon I was riding him hard, up and down onto his bulging shaft, forward and backward, swinging my breasts into his face, my eyes looked at him with raging lust. I held nothing back, my grunts turning into screams. My hot pussy walls clenched down onto his shaft and he moaned into my chest. His balls were trying to find sperm to shoot out but it was too soon. His cock stayed stiff and slurped in and out of my pussy. My screams finally peeked, and my body shook with orgasm. I kept riding, his shaft giving me multiple orgasms, until I was too tired and couldn't ride him anymore.

"Still no sample?" I got up and pulled him off the table, and then climbed on it, on my hands and knees. he climbed onto the table on his knees, his cock still raging, its head poking my bottom cheeks.

"When you're ready, pull out and deposit." I was still breathing hard, trying to recover. My pussy still glistened with lubrication and he entered me quickly. I sucked in air and raised my head, feeling him deep within me. Then I turned my head around to watch him, and held the cup in one of my hands, ready to give it to him.

It was a beautiful sight, my tired arms trying to hold my upper body off the exam table, and trying to reach the cup towards him. But each time he rammed into my hot pussy, I lost a little strength, and my body finally rested on the table. He leaned forward and put one hand in the middle of my back and put his weight on me, still fucking me hard, pushing the air out of my lungs. I moaned loud and growled a little. He fucked me harder. I held onto the cup next to my calf, my eyes half closed, sometimes watching him attack me, sometimes closing. My upper lip snarled a couple of times, and my other hand played with my hair. He pounded and pounded his hard shaft into me, desperately trying to get his cum to release, to finally relieve his agony. My juices dripped down our legs and off the table.

He leaned back again and moved his hand from my back to my waist, and with both hands he quickened our already rapid pace. He needed to cum, he was going crazy. His hands firmly controlled my hips as he tried to piston in and out of me as fast as he could. I got onto my hands again and arched my back, letting him control the movement, the cup still in my hand and nowhere near him. I pulled my other hand down between my legs and started fingering my clit. My growls and moans got louder again.

"Oh god, I'm coming again..." I howled into the air as my body shook between his hands and around his cock. He kept thrusting, cause his cum was starting to build again.

"Oh, here we go, come on, I can't take this much longer..." he moaned between breaths.

"Oh, baby, cum for me, I'm so hot for you, I need you to cum." I howled back to him, my body still trembling as he continued to piston into me.

He finally pulled out of me and reached for the cup. I pushed it into his hands and he unloaded into it, his sperm hitting the inside wall of the cup hard. He grunted for a good twenty seconds, his body in spasm and his muscles contracting. I laid down and stretched out onto the examination table, breathing hard, resting my head on my forearm. After he was done, he crawled down and found the cap to the cup, and set the cup on the counter next to my paperwork.

Some of his cum dribbled down his shaft. He walked over to my head and I licked his cock clean. "Thanks for your assistance."

"You're very welcome. Thank you for your contribution, and please come back again, and don't feel shy about requesting me." He smiled and pulled his clothes on and walked out of the door, leaving me still lying on the exam table.
