Arnold woke up and felt someone had a hold of his hand. He turned his head to look and saw it was Janet. She was asleep, so he slid close to whisper to her.

“Janet.” Arnold barely breathed.

“Hmm.” Janet opened her eyes slightly and looked at him. “Yes, handsome?”

“I need the bathroom.” Arnold whispered. “I'm going to be a while.”

“I'm surprisingly not disgusted by hearing that.” Janet smiled and gave him a kiss. “I think I've cooked myself just enough with the sun, so I'm going to move over into the shade.” She said and they both got up off of the blanket. “Over there, I think.” She pointed to a spot near a single tree that was between the cottage and the bonfire on the beach. “Can I keep using the blanket?”

Arnold picked it up and turned away from her, shook it and flicked it, and turned back to hand it to her.

“Thanks.” Janet said and Arnold slipped his backpack back on. “I want to tell you to hurry back; but, all the best doctors say to not rush things like that.” She chuckled and gave him another kiss. “I'll see you when I see you.”

Arnold nodded and walked over to the barbecue pit. “I need the bathroom...”

“There's lots of woods around. Help yourself.” Richard said and waved at the trees.

“...and toilet paper.” Arnold said.

“You need to pinch off a log. Gotcha.” Wayne chuckled. “You can use the bathroom in the cottage. It's the third door in the hallway.”

Arnold nodded and walked the hundred feet to the cottage and went inside.

“He's on the move.” Mark whispered into Detective Tanner's ear and her eyes darted to Arnold's back as he walked over to the cottage and went inside.

“I think I need to visit the little girl's room.” Detective Tanner said and sat up, then got to her feet. She gave him a smile and bent down to give him a kiss, then she walked off towards the treeline. Once she was in far enough, she changed direction and made her way over towards the cottage and around to the back near the shed. She stayed out of sight of everyone, or hoped she did, and then paused when she saw Heather doing the same thing.

Heather came out of the treeline across the way and walked calmly towards the side of the cottage, looked into one of the windows, then she walked around to the back. She peeked in through the window there for a moment and then she went to the back door. She checked to see if it was locked and it wasn't, so she went inside and disappeared from sight.

Dammit. Detective Tanner thought. I couldn't tell if she saw him in there and went in, or if she didn't see him and went in to check. She held in her sigh. Either way, she's now inside and I'm stuck out here waiting to see what happens.

Detective Tanner felt an arm go around her waist and a hand grab her ass, and she sighed. She hadn't told Mark to stay where he was and maintain surveillance on the front door in case Arnold came back out. The hand on her ass gave her a little massage and the hand in front slid up under her t-shirt to touch her belly.

Detective Tanner put her hands on it to stop it from going up any farther. “Down boy.” She said, then felt warm breath on her ear and heard a soft whisper.

“Okay.” He said and then the hand in front slid down into her loose jeans and rubbed her.

Detective Tanner gasped and then clamped her mouth shut, because she didn't want to draw attention to herself. I thought you said you wouldn't take advantage of me, Mark! She thought angrily. You know I can't say anything or even holler if you do something like this!

The hand on her ass moved around to the front and the arm held her steady as the other hand played with her. She couldn't help herself and enjoyed it, since it felt so good, and she thought that Mark was a good looking guy. She shook her head and put her hands down onto her jeans to stop him before he went too far, then his finger slipped inside of her.

“Hnn!” Detective Tanner cut off her moan and then cursed herself for giving him the extra leverage with her own hands. She also regretted asking him to grab her ass as they made out earlier, because he must have assumed that she would let him do even more if given the chance.

Of course, now that he had a bit more access to her than he had a moment ago, she really started to feel good from him feeling her up. Her breathing sped up and she moved her hands up to try and pull his hand out of her jeans, then he dug another finger into her and she came.

Detective Tanner clenched her jaw and ground her teeth together to stop herself from moaning. Fuck, that felt good. She thought, disgusted with herself that she liked it. She berated herself mentally for not turning around right away and punching him right in the face, then berated herself because she let it go on... still let it go on. She wasn't trying to pull on his hand anymore and she let out a sigh.

She looked at the cottage when the back door opened and Heather came out. She stayed perfectly still so that Heather wouldn't look her way, then the hand in her jeans pulled out and she saw that two of the fingers were dripping wet. She blushed a little at the sight of her shame from getting off like that, then the hand disappeared and she heard a soft slurping sound.

Detective Tanner took in a sharp breath. He just... oh, god... he just... She came a little from the thought and that surprised her. Heather walked away around the cottage and then the arm around Detective Tanner's waist pulled on her a little and she backed away from the edge of the trees. It also took her away from potentially getting caught as well and she sighed in relief.

The hands moved down and unbuttoned her jeans. She didn't stop him or say anything as her loose pants dropped to the ground. The hands grabbed her wrists and bent her over a little to put her hands on the side of a tree. She stayed there silently and felt her panties be pulled down.

What am I doing? Detective Tanner asked herself and she honestly couldn't answer.

Having sex with a coworker wasn't necessarily against the police code; but, morally it was pretty bad. They were on an undercover mission and she needed to catch Arnold doing something that would let her bring him in officially. She held in her gasp as she felt him enter her from behind.

Jesus! Detective Tanner thought in surprise. He's blisteringly hot! She thought that for only a second, until she realized why she could feel his temperature so well. He's not wearing a condom!

He started pumping in and out of her at a steady rhythm and wasn't being rough about it, like she thought a desperate man would be doing, just so he could get it over quickly. He should have been rushing and he was actually taking his time.

“We... s-should... s-stop.” Detective Tanner whispered between her involuntary moans. “You're not... wearing a condom.”

“No.” He whispered into her ear.

“You... should... always...” She panted.

“I'm disease free.” He whispered and bit her earlobe.

Detective Tanner convulsed as he found one of her erogenous zones and she came because of it. “Jesus!” She cursed under her breath as he nibbled at her ear and kept moving in and out of her, then his hands were up under her t-shirt. He expertly popped open her bra and started to play with her breasts. How is he doing so many things and not messing any of it up? She asked herself, then he pinched her nipples, bit her earlobe hard, and kept going.

Twenty minutes later, she had come several times and she thanked her lucky stars for picking Mark to be her partner. He wasn't the best lover she ever had, since they hadn't changed positions or anything; but, he made up for his lack of imagination with sheer tenacity.

“Do you want me to... finish inside you?” He whispered.

Detective Tanner moaned as she came, just from the question that no normal guy would ask in the heat of the moment, and she shook her head. “No... you have to... pull out.”

“Swallow it.” He whispered and she nodded her head in acceptance. He pumped in and out of her several more times, right up until he was on the brink, then he pulled out and turned her around. She dropped to her knees without being asked and started sucking on him as hard as she could. In the next moment, he came and she opened her throat and took it all. She kept sucking for several more moments to try and get it all, then she sat back on her heels. She used her hand to slowly pull on him and a bit came out, so she licked it off and swirled her tongue around the tip.

“I hope you liked that.” Detective Tanner said with satisfaction and she looked up. She had expected to see a very satisfied look on her undercover partner's face, and instead she saw something that shocked her all the way down to the very core of her being.

Arnold's nod.

“A-A-Arnold!” Detective Tanner exclaimed.

“Detective Tanner.” Arnold said and stared at her.

Detective Tanner stared back and she couldn't make her mind accept what she was seeing. No. No no. It was Mark that... groped me and... forced me to... Her face flushed with color and she felt herself be filled up with righteous indignation. She stood up and smiled a predatory smile. “I got you now, asshole! You just forced me to have sex!”

Arnold grabbed her by the arms and pushed her back against the tree, to her surprise. He quickly reached down and lifted her up by her thighs to spread her legs open, then he slid himself right back inside of her. Detective Tanner gasped as he pushed all the way in and her mind and body warred with the situation, because now he really was forcing himself on her... and she liked it.

She had him dead to rights for forced sex and she potentially had his DNA as well. She knew if they did a rape kit, they would definitely find some vaginal abrasions, since he was no longer trying to be gentle, and traces of semen. She was sure that she could convince the chief of police to bring Arnold in under arrest. When he was in custody, then she could question him about everything.

Her body on the other hand, had a completely different opinion about having sex with him. Her arms wrapped around his neck and her legs wrapped around his waist, and her body adjusted to having him inside of her. She hugged him tightly and rested her chin on his shoulder as she helped him hold her up. He hit one of her sensitive spots inside and she came several times before she could convince herself that she shouldn't be enjoying it so much.

“N-no.” Detective Tanner whispered into his ear. “You've... killed... and... you can't... please... oh god, why does this... feel so good?”

Arnold bit her earlobe again and she stopped protesting and fighting her instincts to try and get away.

“Good god... fuck... fuck me... harder!” Detective Tanner whispered. “H-harder!”

Arnold obliged and she felt the bark of the tree dig into her back. He let her earlobe go and she leaned back to look at his face. She could see that he almost looked manic as he drove himself into her. It was the look of a killer that she saw and she shivered. It was both a good and a bad shiver, because her mind knew that what was happening was very wrong and her body couldn't get enough of it and demanded more.

Arnold stopped moving and hugged her tightly, then moved her away from the tree as he knelt down. He laid her on the ground while still inside of her, then he really got going. The logic part of Detective Tanner's brain shut off as he moved her right into position twelve and she had to bite the webbed part of her hand, between the thumb and index finger, to stop her screams of pleasure from escaping.

Detective Tanner never had sex like that before and she constantly whined as Arnold had his way with her. He made sure that she knew that was exactly what he was doing and she didn't care. Her mind and her body were now on the same page and they both wanted him to keep going for as long as he could. She remembered him in the woods with that girl he had arrived with and she came again in the hopes he would make her squeal, too.

*

Janet sat in the shade against the lone tree and she dozed in and out of consciousness. Arnold had ridden her very well in the woods and her body still needed more rest. She adjusted the blanket and folded it over, then climbed in and used it like a sleeping bag. She fell asleep almost immediately, despite the loud music and the huge party going on barely fifty feet away.

“Where were you?” Kelly asked Heather.

“I'd like to say I went for a walk; but, I went to the bathroom.” Heather said.

“Whoa! Too much information!” Sarah said and covered her ears.

“I wasn't gone that long, was I?” Heather asked with a smile.

“I said TMI! TMI!” Sarah said and shook her head, which made the girls around them laugh.

“Do any of you pretty ladies want to dance?” Todd asked.

“You should only be asking to dance with your girlfriend.” Leann said, being the girlfriend in question.

“You said you didn't feel like dancing.” Todd responded.

“That's beside the point.” Leann said and the other girls chuckled.

“I'll do it, just to annoy you.” Heather said with a laugh and stood up. “Come on, tall, pale and freckled. Let's tear up the dance floor.” She said and took his hand, then led him ten feet away to where a few others danced. She started dancing as if it was a dance club and wore normal clothes and not a bikini.

Of course, that drew the attention of practically every guy on the beach and they watched her dance like her life depended on it, almost desperately, and they all appreciated her efforts. They grew excited at the sight and after a minute or so, the guy gathering broke up and the individuals sought out the girls they had come to the party with.

Some of the girls said no, because they knew what the cause was and were a little insulted that it wasn't them that got their guys in that condition. Most of them actually agreed to sneak off and left the party to find a secluded place in the woods to gain some semblance of privacy and have a little fun.

Mark saw the exodus of all the couples heading off into the woods and he immediately thought about leading Detective Tanner into the woods himself. He chuckled, then he stopped when he realized that she had left quite a while ago to follow their target and hadn't come back. Of course, neither had their target.

He started to get a little worried about his partner and checked his watch, then got up and tried to nonchalantly walk towards the cottage without trying to imply that that was what he was trying to do. He hadn't had a lot of undercover practice, so it came off as if he had a little bit to drink and wasn't quite steady on his feet. He had unintentionally given himself the perfect excuse to head towards the cottage and no one looked his way.

Mark worked his way around the cottage and tried to look in the windows; but, it was too dark inside and he couldn't see anything. He walked over to the back door and tried it. It was unlocked, so he went inside and did a quick cursory search of the rooms. He didn't see or hear anyone, so he went back out of the house.

He walked around to the other side of the cottage and thought he heard someone in the forest. He thought back to seeing their target and that girl, then shook his head. He tried to convince himself that he couldn't in good conscience walk over to the edge of the treeline and peer in to see who it was. He was halfway to the treeline when he decided that he would be lax in his duties if he didn't try and see who it was.

Mark crept over and didn't see anything. He could hear panting and the sound of bodies slapping together, which drove his curiosity through the roof. Now he had to go closer to see who it was, so he very carefully made his way into the woods and followed the sounds. The girl's squeals were almost as attractive to hear as seeing it would be and he became excited as he imagined what they were doing.

Mark walked around the tree and stopped dead when he came face to face with Detective Tanner. She had her eyes closed as she straddled a guy's waist and her clothes were strewn around them. She was moving up and down as quickly as she could and her breasts bounced up and down, which invited someone to grab them and hold them still. She squealed and moaned as the guy held her hips and helped her move.

“What the hell are you doing, Olivia?” Mark asked, and he put as much of a 'jealous boyfriend' tone into his voice as he could.

Detective Tanner felt like a bucket of cold water had been thrown on her at the sound of her name. Her eyes flew open and she saw Mark standing a few feet away with a shocked look on his face.

“It... it's not what it looks like!” Detective Tanner exclaimed.

“She's collecting my DNA and enough evidence to have me charged with sexual assault.” Arnold said and kept moving her up and down.

“Jesus Christ.” Mark said. “Olivia... detective... is that true?”

Detective Tanner opened her mouth to say yes, then decided to tell a different version of the truth. “I thought... he was you.”

Mark's mouth dropped open in shock. Holy fuck!

“We had already... had sex when I... found out it wasn't you.” Detective Tanner said between pants and moaned when Arnold hit one of her sensitive spots. “He forced me to...”

“Outside again?” Arnold asked.

Detective Tanner gasped and stared at Mark's face. She knew that she couldn't take Arnold's load in her mouth with him watching, so she stayed quiet and didn't choose.

“Okay.” Arnold said and pulled her down hard and shot his load deep inside of her.

“OHHHHH!” Detective Tanner moaned and closed her eyes as she came from Arnold filling her up. She braced her hands on the ground and leaned forward to try and calm her breathing. She opened her eyes to look up at Mark and couldn't tell what expression was on his face. “Mark...” She paused, because she wasn't sure what to say.

“That should have been me?” Mark asked and looked at Arnold.

Detective Tanner pushed herself up off of Arnold and onto her knees. “Mark, let me explain.”

Arnold stood up and grabbed his shorts. “Just shove your dick in her mouth. She loves that.” He said and walked away.

“Mark, don't listen to hi-MMM!” Detective Tanner suddenly had a rock hard penis in her mouth and she looked up at Mark's face.

“Goddamn! You look so beautiful like this, Olivia!” Mark said and gripped her hair tightly, then he proceeded to have his way with her mouth.

Detective Tanner seemed to be perfectly fine with that.
