In the afternoon the on occasion sex Derek had promised them was back on Stiles' mind and they couldn't stop glancing over to where Derek was working, seemingly engrossed in what he was doing. But Stiles just knew that he knew that they kept looking at him and that they were getting hornier by the minute just thinking of tonight.
With all the possibilities running through their mind, it took them a while to notice something.
Stiles couldn't pinpoint when it happened and usually, she didn't care about it, it was called genderfluid for a reason, but when she left the office with Derek, she was fully on the she side.
Visiting Erica put her mind on other things for a while. She had to distract Boyd so that he did not notice the black lines crawling up Derek's arm but eventually Erica was fast asleep and Boyd looked beyond tired as well. So she and Derek said their goodbyes and left.
On the ride home, Stiles mulled over her situation. Derek didn't care that much about sex, he would be fine with just cuddling and maybe making out a bit. They could do this another time.
On the other hand, Derek had offered this to celebrate Stiles joining the pack and it felt wrong to turn him down on something he wanted to do for Stiles.
She glanced over to Derek in an attempt to read his mind but no such luck. She felt him in her mind but more in a general way. She felt the pack as a whole and not so much the individual members. It was like a warm blanket she could wrap around her body but not useful in figuring out Derek.
In the end, she figured that Derek would be okay with no sex tonight.
"Raincheck on the on occasion?" She asked, fiddling with the string of her hoodie.
"Sure." Derek parked the car. "May I ask why?"
That was the tricky question. She wanted to have sex with Derek, she liked the way he kind of dominated her in bed. How he focused on her and his own pleasure almost came as an afterthought.
"I'm just not in the mood," Stiles lied.
Derek just raised an eyebrow at her, silently telling her to try again.
Stiles huffed and looked out of the window to gain some time, hoping for Derek to just drop it, he was not interested in sex anyway, but Derek just patiently sat there and waited for an answer.
"You probably haven't noticed yet." Stiles turned back to him, still avoiding his eyes. "I'm a woman."
"You've been drifting in that direction all afternoon." Derek nodded. "What's the problem?"
She'd thought that it would be explanation enough, and partly she waited for him to be repulsed by it, but not with Derek.
"I'm not exactly woman shaped …" She gestured over her lap. "… down there."
There. She'd said it. She crossed her arms over her chest.
Derek thought about it for a moment but then he leaned over. His breath brushed over the lope of her ear, making her shiver.
"You want me to play with your breasts?" Derek whispered into her ear while he reached over to touch her chest. Her very flat chest, he must feel that even through the hoodie.
He put his broad palm firmly on her chest, his thumb brushing over a nipple.
Stiles sucked in a breath and didn't know what to do. Something short-circuited in her brain.
"I want to play with your perfect little titties." Derek placed a kiss behind her ear. "I want to suck your nipples until they are hard and perky. Then I want to move downward." His hand followed his words. With fingers spread wide, he left a hot path from her chest, over her abdomen, until he slipped his hand between her legs. On reflex, Stiles pressed her thighs together which only pushed his hand more firmly against her growing erection. Which was exactly the reason why this was not a good idea. Stiles reached down to remove Derek's hand but he kept talking.
"I want to do the same to your clit." He ground his palm against the root of Stiles' pen... clit, she corrected herself. "I want to suck it until it's hard and perky as well. I want to make you come from sucking your clit. Would you like that?"
Stiles had wrapped her fingers around Derek's wrist to get his hand out of her crotch but now she was pressing it more against her hard clit.
"Yes." She bucked into him. If Derek kept going he might make her come in her pants right here in the car. "Derek, please."
"And then I want to sink into your wet pussy," Derek continued. "I bet you're already wet and loose. You want me to fuck your pussy?"
Stiles threw her head back, this was beyond hot. She might come from the dirty talk alone.
"I'm going to come in you," Derek kept talking. "I'm going to be buried to the root in your hot, wet pussy when I come."
Derek did make her come right there, in the car in the goddamn parking lot.
"See?" Derek rubbed his palm over her clit one last time. "All wet for me."
Stiles didn't answer, she was too busy catching her breath. She had slumped down in her seat, legs cramped into the foot room, head resting somewhere against the middle of the back of the seat.
"Hope you'll still be true to your word with the rest." She cracked an eye open to glance at him. He did look as proud as he sounded. And smug. That bastard.
Stiles needed a moment until she trusted her legs enough to get out of the car and up to her apartment without face-planting.
Once she'd reached her bedroom safely, Derek helped her out of her clothes and urged her to lie down on the bed. Then he did exactly what he'd promised. And some more.
"I like this on occasion thing," Stiles mumbled into the pillow.
Derek cleaned her up before he crawled into bed with her and drew the blanket over both of them. When he drew her close to cuddle up with her, Stiles went with it like a rag doll. She was not moving ever again. Derek just arranged her body until he was spooning her from behind, his nose in the hollow of her neck.
Stiles knew that Derek had enjoyed the sex but this was the part he was really here for. Not that Stiles minded. Fucked out and pliant she snuggled more firmly into Derek's warm body behind her.
It was too early to go to sleep but Stiles let herself drift off for a little while.
"I can't believe how you just roll with it," Stiles said once she was more awake again. Lazily she was playing with Derek's fingers while he kept her close with his arm around her.
"Was it okay?" Derek asked after a long moment. "I kind of just improvised."
"It was amazing." Stiles wiggled free to turn around. Derek was not willing to let her go far, he kept most of their bodies pressed together which ended with their foreheads touching. For a second they just breathed the same air.
"I can't believe that you just know." Stiles cupped the back of Derek's head. "That you're not just fine with it, you shrug and say: Okay, they're female today, I can work with that."
"It's not that hard," Derek said, clearly uncomfortable with the praise.
"I'm a very lucky woman to have you in my life." Stiles kissed him.
"I'm the lucky one," Derek said and hugged her again as if he feared that she would disappear any second now. "I don't deserve you."
"You deserve all the good things," Stiles said to nip whatever kind of dark thoughts were creeping into Derek's mind in the bud. "And I happen to be a good thing."
"You are the best thing that has ever happened to me."
Stiles didn't want to turn this into something emotional so she mirrored Derek's position and slung her arms around him. With their legs tangled and face pressed into each other's neck, Stiles held him for a long time.
The rest of the week went by quickly and then it was suddenly Saturday.
Today Laura would offer Erica the bite.
Stiles had stayed the night at Derek's place, in Derek's bed with him in his human form, and hadn't bothered to return to their own place for the day. So they spent the morning on the couch with Laura, watching cartoons. Stiles didn't know how to describe it but some part of them wanted to spend time with her. And not just because they were friends. A part of them needed her close and after about an hour or so on the couch with her, they were completely in each other's space.
"This is worse than waiting for Christmas morning." Stiles let out a frustrated huff, they were not good at dealing with the anticipation. Nobody knew how Erica would react and even if she accepted the bite, there was still a risk that it would not take. Erica could die. Or she became a werewolf. Or she just said no.
"You telling me." Laura let out a similar huff. "Maybe we should follow Derek's example and work out until we're too numb to think."
"I'm not going to lift weights." Stiles eyed the door to Derek's room as if they expected him to come out and drag them in to join his workout.
"You have no idea how glad I was that I had to work the day I joined your pack," Stiles said. "Waiting is the worst."
"With you, it was more of a pro forma thing," Laura admitted. "You already knew about werewolves and you made your decision to join our pack long before that day. With Erica it's different."
"You still wracked your kitchen with the stress cooking," Stiles teased.
They had seen the groceries Laura had bought yesterday. It was only a matter of time until she had to start with the cooking. It had taken Stiles a little while but now they knew that dinner was not just a werewolf thing about providing for the pack or soften the mood, it was a stress relief for Laura.
Today Stiles joined her in the kitchen. They were not allowed to do much of the actual cooking but they did most of the prep work. And they cleaned up behind Laura so the kitchen did not look too bad when in the evening the doorbell rang.
By then Derek had emerged from his room. He was showered and dressed and he'd even set the table while Stiles and Laura had been busy in the kitchen.
Erica looked good today, Stiles noticed. Not as exhausted as the other day.
Laura wanted them to have a nice dinner first so they all sat down and Laura and Stiles brought in the food.
Erica asked about work which got the conversation going. Boyd had been in a few hours every day but he still missed out on a lot.
They made it to the dessert part in an almost relaxed way but something was looming over the table and in the end, it became too heavy to ignore.
"Okay, what's going on?" Boyd asked, looking from one to the other.
"Yeah, who died?" Erica cracked a joke but there was concern behind her words.
"Nobody has died." Laura pushed her plate away and used her napkin. "And there is a way to assure that nobody at this table has to die anytime soon."
"Sorry to disappoint you but something in here begs to differ." Erica tapped the side of her head with her finger.
"I would appreciate it if you did not joke about that," Boyd said, his voice cold. Without breaking eye contact with Laura, he reached over and put his hand on the small of Erica's back. It was clear that he was ready to get up and leave if that was what she wanted.
"I'm not joking." Laura let the red bleed into her eyes.
