Start analyzing blood samples

"Ha. Right. Sara, I'm not going to cheat on your sister."

"What about you and me?" asks Sara.

"We're not cheating. It was Nicole's idea that I be your provider."

"But you could just jerk off into my mouth to treat me. You don't have to fuck me to treat me. You fuck me because you want to. You fuck me because I want you to. You fuck me because Nicole wants you to."

"I don't know! Okay?" you start. "This whole thing is weird and complicated and--"

"--and fucking hot," interjects Sara.

"Yes, and hot. But we're navigating it. And just because you and I are... doing what we do to get you your medicine, doesn't mean that I'm going to start fucking every girl in town, okay?"

Sara nods, which makes her big tits jiggle.

"Okay, now go put some clothes on. I'm going to try to get some work done," you say.

Sara goes to her room to get dressed.

With Nicole at work, and Sara temporarily satisfied, you decide to start analyzing the blood samples Jenny brought over. You set up the equipment she brought you, a small centrifuge, a spectrometer, blood chemistry analyzer, and a powerful microscope, among a few other things and fetch the samples from the fridge. You load the first set of samples into the centrifuge and turn it on.

Sara emerges wearing a pink crop top that shows off her flat stomach and accentuates her massive bust, along with skintight white short shorts and high-heeled wedge sandals. She approaches your makeshift lab.

"I'm going to go meet my friend Alicia for a little bit. I'll be back in a few hours."

"You sure you'll... be okay?"

"I just swallowed most of your load like five minutes ago! And we're just going to the mall. If I start feeling anything, I'll just Uber home right away."

"Okay, have fun."

When you say that, Sara grabs you and kisses you deeply, her tongue eagerly searching for yours. After a few moments, she breaks the kiss.

"See you later!"

And she cheerfully skips out the door. _Fuck me. What have I gotten myself into? _Her kiss got you rock hard. Just get back to work, think about blood, think about blood...

You sit back down and resume your work. Before you know it, hours have gone by and you've finished three sets of blood samples. The only thing that shakes you from your work-trance is your growling stomach.

You check the clock. 3:32pm

With a yawn and a stretch, you pack up your lab equipment and bring the blood samples back to the fridge. Then you pull out some leftover chicken and mayo and make yourself a sandwich.

Just as you're sitting down to eat, your phone buzzes. It's a text from Jenny. It's a bunch of text from Jenny.

JENNY: BOSS!

JENNY: Winslow is fucking pissed.

JENNY: He sez the sperm sample you gave me was half SALIVA.

JENNY: WTF John?

JENNY: Why was your sample half spit? Did you cum in your own mouth?

Fuck. You have to respond.

JOHN: No, I didn't cum in my own mouth.

JENNY: Who's mouth, then? Was Nicole hiding from me?

JOHN: Yeah, it was Nicole.

JENNY: LIAR!

JENNY: She called me from work to tell me you weren't coming in.

JENNY: So who was it? Who's the lucky girl?

JENNY: Ooh! Or guy? __

JOHN: Shut up! You can't tell anyone.

JENNY: Of course.

JOHN: I mean it. You tell ANYONE and I'm firing you.

JENNY: I swear.

JOHN: Nicole's little sister has the disease, and I've been treating her.

JENNY: NO WAY!

JOHN: Yeah. She moved in with us.

JOHN: Just keep your mouth shut.

JENNY: I need to come get another sample from you in the morning, so you tell her to keep HER mouth shut

JOHN: Fine. See you tomorrow.

JENNY: Can't wait to get a load of your hot cum!

You put your phone away and bite into your sandwich. Just then, someone puts their key in the lock.
