I was at the sperm bank, feeling really self-conscious because I'd been in the room with my little plastic cup for a half hour and I guess because of the pressure, I was having a hard time getting it up.

It didn't help that I was there in the first place because I was having trouble getting my wife pregnant.

My penis kept going soft on me, and I was really fapping it hard with a lotion palm, still trying to get it up when I heard a knock on the door and the nurse outside asked if I was doing okay.

No, I wasn't doing okay. I was so embarrassed.

"Yes," I said, trying not to be too loud, still trying to concentrate on the picture of the fat ass on my phone screen, sticking her big fat bottom up into the air and looking over her shoulder at me with a grin. Now my penis was completely soft again, like a small worm in my hand, and I was working so hard I was sweating.

This was my favorite photo of all time, and at home I could get off to it in under a minute if I needed to, it was so sexy, especially when it's been five days since my last nut like today.

Finally, I got up the courage to put my clothes back on and leave the room to tell my nurse that I didn't think I could do it.

When I handed her my empty plastic cup, she said, "It's okay. This happens all the time."

She asked if I needed a magazine or something, and I said that no, I had my phone, but then I wished I hadn't said anything at all.

Just then, I heard a door behind me open, and I glanced back over my shoulder and saw a big burly guy with a fat belly striding out with a red face and a big grin.

He handed his cup to his nurse, and I noticed that his was completely full of his whitish-yellow load, and when he handed it to her he chuckled, "My cup runneth over," he panted.

I'll never forget the wide-eyed look on her face that I could tell was more than just shock.

"Don't worry, I cleaned up after myself," he chuckled again.

He kept on walking for the exit seemingly without even noticing me, and my nurse grinned at him with a red-faced smile of her own and said, "Oh my god." She made eye contact with the other red-faced nurse and then hurriedly touched me on the shoulder. "I'm so sorry," she said. "It's okay, let me go get you something that might help."

The nurses shared another blushing glance as my nurse walked past the other one to the sink and the one holding the cup held it in both hands like you'd hold a hot cup of coffee on a cold day, then marked it with a Sharpie.

"Still got the spunk!" I heard the guy laugh to someone as he walked back out into the reception area.

"Give me what you gave that guy," I said, and the two nurses laughed. That broke the ice, and I went back into my room with a warm wet towel and a Hustler magazine and ejaculated into my cup just thinking about that big fat load in the nurse's hand.

It's funny what gets you off sometimes.
