For a few years I worked the graveyard shift at an IT helpdesk. That’s where I met Sheri. There was a lot of downtime between calls and we would often get to talking. After a few months we became friends. After a year we got really comfortable with each other. One day we were talking about mental health issues and she hit me with a revelation. Ever since she broke up with her high-school boyfriend she’d struggled with moderate depression. She’d tried talk therapy and medication but nothing really worked. She had developed a theory. Her ex-boyfriend was sterile, owing to an accident involving his vas deferens and a barbed wire fence. When they had sex, they didn’t use birth control. Since that breakup she hadn’t had another sterile lover. She couldn’t take the side effects of hormonal birth control so she at all times used condoms.

“So then I read an article about a study where they showed that women who are frequently…uh…inseminated report less depression. And then it clicked. I had depression before Chris and then felt fine while we were together. After we broke up the depression came back.”

I opened my mouth and then wondered better of the idea that had popped into my head. She noticed. “What?”

“Nothing” I said and turned back to my workstation.

“You were going to say something.” she accused.

“It was dumb.” I said without looking at her.

“Cmon. What was it?”

“Yeah…this wasn’t an HR safe thought.”

“I promise I won’t tell. What were you thinking.”

“Well…before my divorce I got snipped. I could…like bring you a sample in a cooler or something and you could test out your theory. Saying it out loud, it sounds even dumber.”

“That’s really sweet. Kinda icky but sweet.” she said with a big smile. We both looked at our screens for a minute. Then, “would…um…would you not prefer to deliver the sample directly?”

“I didn’t mean to suggest anything, I just like to fix problems. I’m sorry.” I said still stinging from the “icky” opinion.

“Don’t be sorry. I’m really touched that you want to help me like that. Also I’m serious. I’d prefer to just get a direct deposit.” She was no longer looking at her screen. The gears turned slowly in my head, when the input finally finished processing and I understood the situation all I could do was nod like an idiot and smile.

She rummaged around in her purse and then fished out a tiny bullet vibe. “Mind if I enjoy myself?” she asked.

“Of course, yeah” I stammered. She got up, spun her chair around, pushed it up against the desk, and raised it up as far as it would go. She reached under her skirt and removed her panties, then got onto the chair on her knees, facing the back. “Give me a minute to get ready” she said as she pulled her skirt up and slipped the vibe between her legs. From where I was sitting I could see her slide it up and down her pussy, which was getting wetter by the second. “OK, come on over here. Take it slow at first OK, it’s been a while.”

I got up and went over to her desk. The height of her chair was perfect. I wet the tip of my dick on her labia and then felt around for her vagina. I went in little-by-little, pulling back out now and again to wet the shaft. After a few minutes of work I was fully inside her. “Are you OK?” I asked.

“Yeah” she purred, “Yea I’m OK. Keep it slow please, and when you’re done stay inside as long as you can OK?” I didn’t answer but pulled out slowly just a bit and then thrust back in even slower. She tossed her head back and inhaled a long ragged breath. “Sweet baby Jesus that’s nice” she said. I did it again, just as slowly. “More,” she panted, “pull out a bit more.” I pulled out halfway and then slid back in, still super slow. “More” she breathed. I pulled almost all the way out and then went back in, pressing myself against her.

I paused. “I’m close.” I said almost apologetically.

“Oh god, cum in me please.” she begged. I pulled out again and then thrust in one last time. My legs shook and my head swam as I filled her up with pulse after pulse of cum. It had been a while for me too. When it was done I fought to stay standing so I could fulfill her request to stay inside. She was making good use of the vibe. When I regained my balance I used what was left of my erection to press against the walls of her vagina. “Keep doing that” she hissed. She drew a breath and held it. Then she hyperventilated as her legs shook and her pussy clenched around me. It felt like she was trying to squeeze out the last drops. Her orgasm subsided and her leg muscles relaxed. Her ass sagged down, which made my member shift inside her. She shuddered and pulled away. I popped out of her and dribbled a little cum on her feet. She laughed and then sighed and said, “That was the best healthcare I’ve ever received.”

The next week she had me sit on my chair while she rode me. She held onto my shoulder with one hand and kept the vibe between us with the other. It felt kinda nice against my pubic bone. I held her ass with both hands to keep her from sliding off. “Press on my anus” she whispered into my ear. I followed instructions and was overcome by how hot it was. I didn’t have time to warn her. She reached orgasm just after mine started. Afterwards she slumped against me and warned me not to move a muscle. We stayed like that for a good five minutes, both my legs fell asleep.

The week after that we cleared off my standing desk and used the height adjustment to get her pussy just right. She laid on her back on the desk and I fucked her proper. She came well before I did and dropper her vibrator. I asked if she needed to stop, but she shook her head and then bit her hand. I kept going and she had another orgasm before I administered her weekly injection.

Then suddenly it stopped. We’d had sex three Mondays in a row and then nothing. By Friday I had decided it was a fluke and had ended. I was disappointed, but I didn’t want it to ruin our friendship so I decided not to say anything. I was standing at my desk when she rolled her chair over to me. “Get our your dick”, she ordered.

“Come again?” I asked confused.

“No thanks, I took care of myself earlier” she said with a giggle. I just gave her a dumb look. “My aunt Flo is in town,” she explained, “I had hoped to be done with it by today, but no such luck. Anyway, it’s Friday and Baby need her medicine, so make with the dick.” My dumbness intensified. “I haven’t felt this great in years. I’m betting the treatment will be at least partially effective if delivered orally. She smiled from ear to ear and winked.

“Oh.” I had finally caught on. “Yeah I guess any mucus membrane would probably work” I said as I undid my belt and fly. “We should totally test out various applications. You know, for science.”

“Various?” she said with a smirk. “Well you’re not that luck today, but we’ll see.” She left me to ponder the meaning of that while she licked every inch of my dick, from head to base. I was close to figuring it out when she suddenly sucked me into her mouth and then down her throat. She bobbed her head while turning side to side. After a few seconds she came up and worked the head around in her mouth with her tongue, while she stoked the base with her hand. It was too much. I exploded in her mouth. She took the first strong jets on her tongue and then let me finish down her throat. When I was done she let me go and showed me her mouth full of cum. The she swallowed it with a grin, got up and sauntered over to her desk.

We both eventually moved on to other jobs, but we have kept up our mutual advantage relations. She says she’s not interested in dating, and neither am I. We meet up at a hotel once every week. One such tryst took an interesting turn and I finally understood what she had meant just before that first blowjob. I had gotten used to sex without fuss, but one day she asked if I had extra time. I had nothing planned that day so I agreed. She spent a long time in the hotel bathroom before she finally joined me in the bedroom. She was wearing nothing but a pair of crotchless panties, that sported a built in vibrator. She explained that it was time for some experimentation as she handed me a bottle of lube. She hopped onto the bed and hugged her knees. “Use lots of lube, go real slow, and not too deep.”
