For the past several months, my wife and I have been trying to get pregnant.
I knew she was serious when she’d downloaded an app on her phone that would tell her the days of the month which gave us highest likelihood of conceiving.
We have been married for only a couple of years, and I am still very much attracted to her, so it’s been no chore—We’ve tried everything: Fucking in the kitchen, humping in the back yard, making love in the bedroom.
I’ve ridden her ass, I’ve buried my cock in her cunt missionary-style, and I’ve humped away at her like a pubescent boy getting a lucky crack at a MILF with her legs spread wide.
Each and every time, I’ve sprayed my warm nut deep inside her, but so far, no luck.
On Monday of last week, our doctor sent me to a sperm bank where I would “give a sample” (jack off under pressure) so that they would be able to test my sperm count.
“If you’re shooting blanks,” my wife had said right before I’d left the house, “I swear to Christ you’re going to have to find me a fucking bull with a big ass dong to nut inside me.”
My wife is known to have a dark sense of humor, but she is also sexual to the extreme, and so her comment had me feeling a little out of balance as I entered the sperm bank and checked in at the desk.
As I filled out the paperwork, all I could think about was my wife with another man. The thought, in itself, sort of turned me on, but when I thought of this beast of a man gushing inside her and giving her what I would never be able to, my heart sank.
“Mark,” a sexy blonde nurse with big tits said, standing in the open doorway to the back, holding a clipboard cradled in her right arm.
Mark is a fairly common name, so I glanced around the waiting room quickly to make sure it was, in fact, me she was calling before I stood to follow her.
Her gaze was straight at me, and nobody else responded.
As I locked eyes with the nurse who’d just said my name, the nurse who knew full well what I would be getting up to behind closed doors, I began to get stage fright.
I was excited, embarrassed, and nervous all at the same time.
As she led me toward the back, her fat ass wagged back and forth beneath her tight pink scrubs, and her thin waist had me fantasizing about blowing my load right there on her warm back instead of in a sterile plastic cup.
When we arrived at another open door (this one looked like the room where I would be “depositing my sample”), my blonde nurse stopped just outside the door and held out an arm indicating that I should enter.
“Make yourself comfortable,” she said. “Would you like some reading material?”
I blushed. “I’m fine,” I said. I had my phone for porn, but I thought maybe I’d just stroke to the thought of the sexy nurse instead.
“I’m Alexis,” she said, and before closing the door, added, “I’ll go get the cup for your specimen and be right back.”
She left, closing me into the small, sterile room that felt more like a doctor’s office than any place I would care to jerk off in, and I started to feel odd about the whole thing.
Would there be a time limit? How long was too long to be in there? How much semen was needed? (To say the least, I was quickly getting into my head and needed to get out again as soon as possible.)
Before long, I heard the quick knock on the door, and it opened immediately. Alexis sauntered back into the room, her hips still rolling as she approached me, more like the waves of the ocean than a female human.
She handed me a sterile cup, a dry, neatly-folded wash cloth, and a small, travel-size bottle of body wash. She motioned toward the sink. “Wash your hands and penis,” she said, “And make sure they’re dry before you give your sample.”
I took the items from her, and our hands touched inadvertently in the exchange. (Her hands were warm.)
“After you’ve washed and dried, you’ll ejaculate in the container, close the lid, and leave it on the counter.”
“Okay,” I said. Hearing this nurse say the word ejaculate had caused my cock to come alive inside my pants.
With that, she left, and I began to wash up.
Once I was finished, I decided to try it the old-fashioned way: Sitting on the edge of the table, using nothing but my imagination.
I imagined Alexis’ huge ass in the air, her tight waist and muscular back forming a ramp downward to the floor, down which my spurts would eventually run in a warm stream.
I imagined myself fucking her pussy and then fucking her ass.
When that didn’t work—I was barely even hard at that point—I scrolled through porn on my phone, looking for a woman whose body closely resembled that of Alexis.
No one could compare—I was fixated.
I tried stroking to some of my all-time favorite photos, but they failed me also.
After what felt like half the afternoon—In reality, I had probably been back there for 45 minutes—I was desperate.
I put my clothes back on and walked back out to the nurse’s station.
Alexis eyed me, up and down, obviously wondering if I’d completed my assignment.
“I’m having trouble,” I said, and with a knowing (and somehow reassuring) grin, she placed a hand on the small of my back and guided me back into my room.
This time, she entered behind me and closed the door behind us. “Don’t feel ashamed,” she said. “This is completely normal.”
She walked over to the sink, rinsed out my rag with warm water, and asked me to undress again.
When I hesitated, she asked if I was comfortable.
“Yeah,” I said, and I began to undress again right there in front of her. She was a nurse, after all, and she seemed to be a good one.
When I was completely naked, she asked me to lay back on the small exam bed, and I obeyed her. “Try to relax,” she said.
“Do you mind if I touch you?” She asked. “Not in a sexual way,” she added. “We just need to get you clean again after you’ve had your clothes on.”
“That’s fine,” I said, laying back and trying to relax like she’d asked me to.
I felt the warmth of the rag on my cock as Alexis took it in her hand, stroking it gently, just a bit, to be sure it was nice and clean. She was the picture of professionalism, save for one moment: When she had finished washing me, she reached out with her fingers and gently caressed the tip of my cock on her way back over to the sink, taking a string of precum with her.
I was alive now.
“I wish you could stay,” I said as she handed me back my small plastic cup and turned to leave.
“Hang tight,” she said. “Just try to relax.” With that, she left the room and closed the door behind her.
Relax? Was she coming back? It sounded like it—I certainly didn’t want to hurry and cum in the cup and miss out, but what if I’d just misunderstood her? What then? I’d be in there all day if I stalled and forgot the feel of her fingers on my hard cock head.
I began to play with myself, gently, in no rush now, lying back on the bed and stroking slowly to these new sensual thoughts. (I wanted to be ready in case she did come back.)
My cock began to take shape.
Suddenly the door opened (there was no knock this time), and a petite brunette nurse with a big ass, her long hair pulled back in a ponytail, entered like she’d done this thing a time or two.
“One of the lucky ones,” she said after she’d closed the door softly and locked it behind her. “Come on, then,” she said, shimmying her pink scrub bottoms down over her wide hips and pulling them down to her ankles. “You want it the old fashioned way.”
She looked back at me like, what the hell are you waiting for, as she knelt on the tile floor and peeled her blue thong out of her ass crack, down over her big hips, and finally down to her knobby knees spread there on the tile.
I was off the table in no time, stunned, but what the fuck?
The first thing I noticed was the large dark target that happened to be her butthole, but below it (and this is rare for me) was an even better target.
I began to shake as I approached her big behind, sticking right up in the air in front of me, her pink slit already glistening with precum.
I squatted behind her, and as I took my now throbbing cock in my hand and rubbed it against her pussy, she flew forward and skittered away from me toward the door, pants around her ankles. “What the fuck are you doing?” She screeched.
“I thought you were here to help me,” I said, innocently.
“I am, dickbrain” she said, her brow furrowed now, frowning. “You can jack off to my ass, but don’t fucking touch me,” she said.
“I’m so sorry,” I said.
Acknowledging the misunderstanding, she reassumed her position on the tile floor: Face down, ass up.
I knelt behind her with my plastic cup and began to sensually stroke my cock, though my hands shook.
“Just like that, baby,” the new nurse said. (She was very good.)
I focused on her butthole now that everything was off-limits and noticed she let some pubic hair grow there in her dark crevasse. I shook with the exotic excitement of attaining the forbidden.
A thought occurred to me.
“Can I smell your ass?” I asked. “As long as I don’t touch anything?” I felt like a weirdo, but she was thankfully receptive.
“As long as you don’t touch me, you can do whatever you want,” she said. “I’ll need that sample though.”
Heart racing, I took a knee and knelt over her. I put my nose an inch or so from her bottom and slowly sniffed the scent of her butthole. Oh fuck…I pressed the head of my cock against the hard and too-small opening of the plastic bottle, right there in the crack of her ass, and the smell of her big stinky bottom made me dizzy with euphoria.
I shot my nut deep into the plastic cup, and she must have realized (I’d hollered as I’d ejaculated), because just then, she reached back and grabbed a hold of my balls before immediately letting go again.
“Good boy,” she said, standing and pulling her pants back up, wagging her ass to get them back up over her large hips. “I’ll take my sample now,” she said, holding out her hand.
I passed her the warm bottle of nut that was damn near full to the brim, and she just winked over her shoulder at me on her way out of the room. “That must have been hard to hold in,” she said.
Immediately, Alexis appeared back in the doorway, told me to dress, and said they’d be calling me in a few days.
When my wife asked how it had all gone, I wished I could vent to her about the smell of that nurse’s stinky bottom. I couldn’t get it off my mind.
Instead, I just locked myself in the bathroom and masturbated again to the scent that was still so fresh in my memory.
As I pictured that ass, I now mounted up on it. I humped her like an animal, her scent driving me mad, and I almost immediately ejaculated a load like before—a big warm load—into the palm of my hand.
I may need to go back to the sperm bank for a second opinion no matter how the test comes back.
