13. Experimentation can be fun

Later in the Chem lab, while Willow was drawing the blood and testing it, Buffy had to restrain her desire to taste it. There was definitely something going on here that wasn’t right. She shouldn’t crave the taste of her own blood. Suddenly she had a horrible thought, ‘What if I start to crave the blood of others, like a vampire?’ She knew she couldn’t stand to live like that. She was on the edge as it was.

Willow just had to be able to find something with all her centrifuges and sciency equipment!

“Nope. Nothing. Perfectly normal, everyday human type O blood. Nothing special about it at all.”

“Are you sure Willow? Maybe it’s something that wouldn’t show up on a normal blood test. Maybe it’s something magical.”

“If so, I’m not going to find anything this way. But, well, we could try another type of experiment. Instead of trying to isolate and quantify something different about your blood, we could set up a controlled experiment, and see what happens.”

“Isn’t that what we’ve been doing? I mean, with all the lab stuff and everything?”

“I mean we do it at your house, when your Mom is out of town. We both agree that we won’t leave the house no matter what. Then we each sample some of your blood, and wait and see if anything happens. Most likely, we’ll just have an old-fashioned sleepover with movies and ice cream. We haven’t done anything like that for quite a while.”

Eagerly, Buffy agreed. “We could even do it tonight. My Mom’s already in L.A.” Buffy didn’t want to admit that she was looking forward to it. It had been days since Angelus’s last visit, and she hadn’t yet gotten to the point where she would drink from herself.

Once they reached Buffy’s house Willow set up the equipment she had borrowed. Being Willow, she carefully measured out a few vials of Buffy’s blood and labeled them. Her idea was that they would each drink one sample every half-hour. If nothing happened after three separate drinks, they’d conclude that the blood had no affect. Of course she had to estimate how much a vampire might actually drink if he didn’t want to harm his victim. And she had no idea how much might actually be necessary to produce a reaction.

Willow grimaced as she forced the warm liquid down, but Buffy was well used to the taste by now. She waited a minute. “Feel anything, Willow?”

“Nope. How about you?”

“Not sure. Maybe it needs a male presence or something.” Buffy tried to hide her disappointment. She tried not to react as Willow licked her lips, unconsciously making sure that she had swallowed every last drop.

“Maybe beginning to feel a little something.” Willow prevaricated. “We should be writing this down.” She pulled a pad of paper out of her backpack and the girls sat in silence for a few more minutes by the kitchen counter while Willow scribbled some notes.

Finally finished, Willow lifted her head and faced Buffy directly, “So, you gonna tell me what it’s like?”

“What what’s like?”

“Sex. I mean, you’ve been with a least two guys, three if you count Angel and Angelus as different people…”

“Oh, they’re different alright.”

“But they’ve got the same body – right? So how different can it be?”

“As night and day, Willow. Angel was sweet. Gentle, and very patient. It was like… well, when I was little I remember first learning to ice-skate. At first I was scared of the ice, afraid that I’d lose control, not be able to stop myself and I’d fall and get hurt. Angel was like my Mom. Patient, held my hand until I felt comfortable, answered questions, let me go at my own pace. But another kid I knew, her Mom just pushed her hard and threw her out on the ice. She had to figure it all out for herself. Angelus is kinda like that.”

Willow giggled. “And Spike? Did he take you skating too?”

Buffy thought for a few moments. “Being with Spike was more like ice dancing. With a partner, you know. But not like those wussy guys in tights, that look really gay. Maybe it’s because I’d had more experience before I slept with him, but it didn’t feel so much like there was any teaching or learning going on. Just…sex.”

“And that’s good, or bad? I mean, who was better?”

“Huh?” Buffy seemed to have been lost in her memory for a moment.

“You just described three different experiences, Buffy. I want to know what it felt like and which was better.”

“It’s not like that,” Buffy stammered. “You know that old song, ‘Love the one you’re with?’ It’s like that. All good.”

“Even when you didn’t want to…?”

Buffy’s first thought was confusion. How did Willow know about that first time that Angelus had forced her? She didn’t want Willow to get any wrong ideas about how dangerous Angelus was – and in itself, what did that say about her motivations and her thinking process?

Willow pressed her question. “Buffy, I mean, you said that you didn’t want to have sex with Spike – didn’t you? I thought you said that Angelus made you do it as a punishment. But then you said it was all good.”

“I…no. You don’t understand, Willow. I didn’t want to. I mean I would never have chosen Spike on my own.” Even if he is the hottest thing this side of the hellmouth. “At least not at first. But he didn’t force me.” Not like Angelus. “They both convinced me that it was the lesser of two evils at the time. I mean, I, eventually, agreed. After that, well, I guess you could say that Spike seduced me. I mean, it wasn’t exactly like he could have forced me from his wheelchair, even if he had wanted to.”

“You did it in the wheelchair?”

“No. We did it in his bed. But Spike was still mostly immobile. He couldn’t…. I had to…”

“Buffy, I don’t think I’ve ever seen you that shade before. Your face is the color of my hair. I wouldn’t have thought it possible. But then, I’m hearing about a lot of things that I never would have thought possible. So spill.”

Buffy didn’t know why she felt compelled to answer Willow’s questions. Why they were talking about this at all. She was so embarrassed she thought she was going to die or pass out any minute. And it was so hot in here, that didn’t help. She unbuttoned her sweater and took off her over shirt. How could she put this, so she wouldn’t just curl up and die?

“He used his tongue. All over.”

“You mean he didn’t…” was Buffy saying that they didn’t really have intercourse?

“Not at first. It was difficult since he couldn’t move his legs or his hips much. I had to… he couldn’t… I mean, I love it when Angelus slams into me, but this…well, I had to… take charge. I mean… on top. You know how much I love being the one in charge.”

“Mmm,” Willow agreed without thinking. “I mean, sometimes you can be a bit bossy, yeah. But that can be a good thing too.” Willow looked lost in thought for a moment. “You know, it’s been almost a half hour now and I don’t feel any different. I think we should try the second dose.”

“Yeah it really doesn’t seem to be working…”

Two more shots of blood later, Angelus was looking for Buffy. He could tell that she was inside the house, and that Willow was with her. And he could detect traces of other scents too, and those bothered him. There was a faint odor of blood, Buffy’s blood. And he could smell her arousal. He hadn’t come a moment too soon, his girl must be missing him badly again. Just the thought of it made him smile. All he had to do was get her attention so that she could come up with some excuse to send Willow away.

He climbed up the tree so strategically placed outside her room and peered in the window. If he had thought that the smell of her arousal had affected him, it was nothing compared to the sight of what was going on inside Buffy’s room. His anger and his arousal were so strong he would have fallen out of the tree if he hadn’t been so familiar with its branches it was almost like a second home. How long had this been going on? Is this what Buffy did on the nights when he didn’t take her?

Buffy was splayed out on her bed, her hair covering the white pillowcase, while her head thrashed back and forth. Totally nude, her legs were wide open and she was fondling her own breasts. Also nude, Willow crouched near the bottom of the bed, her face buried in Buffy’s warm cunt.

There was no way that he was going to be able to get Buffy alone, even if she was willing to leave Willow for him. He’d have to stay outside, watching, and do what he could to alleviate the sudden insistent pounding in his groin. He was so hard he could probably bore a hole in the tree.

Watching the scene that was unfolding before him, he contemplated the many ways he could make the Slayer pay for what she was doing to him. He’d have to think of something more inventive this time. This time, she was going to get something that she would never forget.

His smile grew. Oh, yes, he knew the perfect way to make her pay for this transgression. She would learn that her body belonged to HIM, and it was up to him what she was and wasn’t allowed to do with it.
