Most of these stories are standalone, so you don't have to read them all. This one, however, calls back (slightly) to Pt 20.

I'd been talking to Lisa at work, and she was whining about wanting to get laid. An idea started to form in my head. I called Dan.
"I have a favor to ask," I told him.
"This doesn't sound good," he said, "what's up?"
"I'd like you to have sex with my friend Lisa."
"Why?" he asked.
"Well," I said, "she's been really focused on her career, and told me she misses sex, but doesn't want a relationship."
"Can't she just go and pick up some rando in a bar?"
"She wants somebody trustworthy," I said.
"And I'm the best you can do?"
"You're trustworthy, and you're good in the sack. It's not like she'll have some clown cum after 3 thrusts and be frustrated."
"And you're OK with this?"
"Yes, it's my idea."
"What's wrong with her? Can't she go on Tinder or Bumble or whatever?" he asked.
"There's nothing wrong with her."
"Is she ugly?"
"No."
"Obese?"
"No."
"Smelly?"
"No."
"Then why can't she get a real date?"
"She doesn't want a real date, she just wants sex," I said. "Please? I'd like to suggest it to her, and I'll bring her over. We can go out, if you'd like to get to know her a little, but she's really nice, and you can always say no when you've met her."
"Does she have any weird kinks, like she's going to kill and eat me after sex?"
"Not that I'm aware of."
"Well that makes me feel much better," he said. "Fine, bring her over some time."
"When?'
"Surprise me."
Later on, I suggested this to Lisa, and she was really embarrassed, and didn't want to talk about it.

About a week later, Lisa asked if she could meet Dan, so we went to his place that weekend. I knocked on the door, and when he opened it, led her in and introduced them.
We all sat down in the living room.
"So I understand you're not looking for friends, you're just looking to get laid," he said, getting straight to the point.
"Yeah, pretty much," she said.
"Well that makes things easy. Shall we get started?"
She stood up, smoothing down her skirt. He stood up too, and started towards the bedroom. We followed him.
"So now you want to watch?" he asked me.
"I'm just going to make sure she's OK," I said.
In the bedroom, they undressed. Lisa seemed shy, and covered herself a little.
"So, how do you want to do this?" Dan asked her.
"Missionary, I guess?" she said.
"OK," he said, "lie down."
She laid down on her back on the bed.
"Can we use a condom?"
"Certainly," he said.
He stood up and opened the drawer in the bedside cabinet, and pulled one out.
"Let me," I said.
I took the packet from him, and sat on the edge of the bed to open it. Once I'd got it out, I took hold of his cock and sucked on the head for a minute or so to get him properly hard, then unrolled the condom.
He knelt down on the bed between Lisa's spread legs, and rubbed lined his cock up with her pussy, and rubbed it up and down a few more times, causing her to shudder.
He slowly pushed his cok into her, then started gently grinding away.
"Is this OK?" he asked.
