Advanced Primatology Ch. 06

"Sanjana," he groaned.

"That one was too easy," she teased him as she squirmed her chest away from him. "But you still get your reward."

She reached back and held his cock in place while she impaled herself on it slowly, gasping as it entered her and she settled her ass down all the way to his balls. He was pretty well endowed, Elise reflected, and this might be one of the bigger ones Sanjana had been fucked by. And she was really fucking it good now! She was slamming down on his cock so hard that his balls were shaking and her ass was shaking too. It looked beautiful. Elise held Kevin's heel to her crotch and rubbed her juices all over it.

It went on like this for ten minutes or so. Sanjana fucking Kevin with her big ass while Pamela rode his face with her skinny one. Then the girls would switch places. He had some impressive stamina. Pot could do that for guys, if it didn't make them soft, which definitely wasn't the case with Kevin. Elise was watching Pamela ride him smooth and slow with her skinny ass when she saw that tell tale sign at the base of his cock as the big vein up the side of his shaft started to expand and pulse. She tapped Pamela on the shoulder and she moved aside so Elise could finish him off like they'd agreed.

She pulled her tits out of the black lacy bra again and lowered them to his mouth while she pounded his shaft and he grunted and groaned. Then she rose up off him and held her crotch a foot or two above him while he thrust his hips up as high as he could in the restraints and searched for her with the tip of his cock.

"What the matter, sweetie, you can't reach far enough? You can't find my pussy? Should I untie you now so you can fuck me however you want to? Should I let you fuck me hard now so you can finish inside me and those big balls will feel all better?"

Kevin was nodding and grunting and thrusting his hips, almost desperate to get inside her again, almost whimpering. Elise laughed with delight then lowered herself back down on him again and reached forward to pull the blindfold off. Sanjana and Pamela were sitting on either side of him with their legs spread wide and their fingers inside them. Everyone was moaning and bucking their hips and gasping for air. Elise was giving him the best ride he'd ever had in his life by far and the fact that he just had to lay there and take it from her made it that much hotter. He was about to blow and so were all three girls.

"Hmmm now," teased Elise, as she caressed his balls and rode him a little slower. "Should I keep all this cum for myself or should I let the other girls get a taste too? What do you think stud? Do you want to cum inside me or would you rather cum on all three of our faces?"

Kevin tried to answer but Elise smothered his mouth with her tits.

"What's that sweetie? Well, it doesn't matter. I've already made up my mind."

She pulled her tits from his mouth and leaned back until her hands were on his shins. Then she rose off him a little so he could meet her downward thrusts with his upward ones. They were fucking like maniacs now and Elise was about to cum hard around his shaft, as much from the idea of what she was doing to him as from the sheer physical pleasure he was giving her. And Sanjana was quaking all over and her big tits were jiggling, and Pamela had her whole hand inside her and when she pulled it out she looked like she was squirting which Elise had never seen before and which brought her right over the edge. Kevin's cock pulsed against the walls of her pussy and a jet of sperm shot right up inside her, hot and quick. It felt delicious. Kevin was grunting and groaning and thrusting his hips and it didn't seem like he would ever stop cumming and it didn't seem like Elise or Sanjana or Pamela would either.

The next thing Elise knew she was collapsed in a heap on Kevin's chest while she scratched and massaged it and purred in his ear. He was making out with Pamela and Sanjana was kneeling between his legs and playing with his cock and he was already getting hard again.

Part 5

Kate was trying to concentrate on the video of Brad and Mahalia on the laptop but she kept getting distracted by all the flirting and sexual tension in the room. She was dripping sweat from all the humidity and they'd been cooped up all day in the common room while the rain poured down in sheets and huge bolts of lightening lit up the lake. She was trying to figure out why Mahalia was quite so fascinated by Brad's "teenaged" cock, and if that meant she was going to go off alone with him when she came into heat and let him mate with her exclusively the whole time she was fertile. And she was wondering if that was maybe a different story to tell about how chimps chose their mates and how genes were passed down than the one all the male scientists tended to focus on, the one about the hot, young "pink lady" who'd been mounted by all the more aggressive males today, but the most times by the most aggressive one who had started guarding her and trying to keep her close.

She was trying to watch the video carefully but she kept getting distracted and she was starting to feel really pissed off at the other women and Chad. None of the women were wearing much of anything at all. They were all comfortable by now sitting around with Chad in whatever they'd be sleeping in or whatever was comfortable to put on after dinner when they settled down to the tedious evening work of going over their notes and logs and maps and reviewing the videos from the day. Kate didn't have a bra on and she was wearing a loose grey tank top with spaghetti straps and a pair of navy blue boy shorts with nothing underneath. And Jess and Karin and Ellen and Courtney were wearing pretty much the same kind of thing. Elise had begged off work this afternoon with an upset stomach. Chad was wearing a tank top and some long soccer shorts.

He was sitting on the couch between Jess's legs while she massaged his shoulders with one hand and read her field notes with the other. He kept rolling his neck to try to work out a kink in it while he tried to work out some problem with the camera at the same time. Ellen was in Courtney's lap on the floor by the wall with some big pillows propped up behind them, and Karin was across the room in a big plush chair with her legs stretched out and her laptop in front of her. She wasn't wearing a bra either and her white tank top was clinging to her sweaty breasts and they looked larger than normal and maybe firmer somehow. Kate had her laptop on the coffee table near the center of the room and she could see all of them from where she was sitting. A couple times she caught Chad starting at Karin's chest (not that she could blame him) and she was pretty sure Karin had caught him too. But she didn't seem to mind one bit, which surprised Kate.

It was really quite a luxurious room. Brian had convinced UNC to come up with some big funds for the trip and the lodge was a rather expensive one, and quite stylish in its own rugged way, at least the women's cottage. Karin looked up from her laptop and asked Ellen and Courtney a question.

"So Elise wasn't feeling well today, huh? That's strange. She seemed fine hiking down the mountain. I could really use her here to help me make out her handwriting in these field notes."

"Um, well, not to be a tattle tale," replied Ellen laughing as Courtney pinched her side, "but I think she wasn't feeling well in the sense that she needed a hot cock injection this afternoon or she was going to lose her mind."

Karin sat forward in her chair and opened her eyes wide. Kate noticed Chad's ears prick up too.

"Really, whose cock? You have to tell me."

"Kevin's," Ellen laughed. "She and Sanjana and Pamela were planning a little party for him this afternoon and I bet she's feeling just fine about now."

"O my god! What kind of party," Jess gasped. "You can't hold out on us now."

"O I don't know," said Courtney, "something to do with all that climbing gear in the big duffle bag, you know, all those ropes and clamps and such."

Jess and Karin busted out laughing but Chad practically leapt out of his chair with an anxious, almost pained look on his face. He looked like he was about to run right over there and put a stop to whatever was happening in the girls' bunkhouse without him.

"O no you don't tiger," teased Jess. "You're not going anywhere right now." She grabbed his shorts by the waistband and pulled him back down on the sofa with her.

"Actually, Jess, could I borrow him for a few minutes," whined Karin, in a voice Kate had never heard before. "My shoulders are killing me from carrying that big pack with the rain gear today and I could use a big pair of hands to work out the kinks."

Ellen and Courtney poked each other and laughed but Jess shrugged her shoulders and walked over to take Karin's seat while Karin stood up and walked over to the sofa and laid down on her stomach. Chad smiled and sat beside her in her tiny maroon boy shorts and started to work her arms and shoulders and neck confidently. He really knew what he was doing and before long Karin was moaning and telling him how nice it felt, and before long Chad had moved on top of her and he was straddling her ass while he worked her back a little lower and Karin gave out little sexy moans.

Kate could tell that it was making Jess a little jealous and to tell the truth it was making her jealous too. Karin was such a beauty and she was in her absolute prime. She was the kind of woman who could make Chad forget about every other female on the trip, including her, if she had a mind to. Jess was crossing and uncrossing her legs and biting her lip and after a while she started to tease Chad and distract him.

"So I wonder what they're doing with Kevin over there? Do you think they really tied him up? Do you think they're all taking turns having sex with him over there?"

"I hope not," said Ellen, "We only have about six or seven condoms left between all of us and I want a few of them for myself."

"Maybe they're not using any," teased Jess. "Maybe they're all riding him bareback, one at a time. Lucky boy. Sanjana is such a hottie with those big boobs and hips, and Pamela looks all nerdy on the outside but I bet she's filthy when she gets that skinny ass moving."

"You don't know the half of it," laughed Courtney. "It's been insane over in that bunkhouse since we got here."

Chad's face was bright red and he'd almost completely stopped massaging Karin by this point. She was hunching her shoulders, and sighing loud, and getting more and more annoyed.

"Do you ladies mind," she snapped, only half playing. "You're distracting my masseuse here with all this sex talk and I was just starting to enjoy myself."

"Yeah, well don't get used to it," Jess snapped back, only half playing too. "That masseuse belongs to me. I've only loaned him to you because your fiancé isn't here and I took pity on you. But I'll definitely be claiming him back in a couple hours."

Ellen and Courtney busted out laughing again, and then Courtney grabbed Ellen tight and kissed her neck a little.

"Actually, that reminds me," Jess continued, lowering her voice. "I know this might be a crazy question, and feel free to say no, but is there any chance I could borrow your diaphragm tonight and try it out? It's not a great time for me and it sounds like rubbers are pretty scarce around here."

Ellen and Courtney were sitting straight up now, wide eyed with disbelief at how much Jess was saying in front of them. Kate felt her irritation rise. She wasn't paying any attention at all to the video now. Karin pushed herself up with her strong arms and practically threw Chad off her.

"Why the fuck would I bring my diaphragm on a trip when my fiancé is on the other side of the planet, and why the fuck would I loan it to you if I had? Are you fucking crazy asking me that?"

You could have cut the air with a knife. Kate took charge.

"Chad, take a walk big boy. The females have some things to discuss."

Chad did as he was told.

As soon as he was gone Kate stood up and tore into the other women.

"Look, can we be a little bit more like bonobos here and a little less like fucking patriarchal troglodytes?"

"What are you talking about?" asked Karin. She was still really pissed off.

"I mean let's use sex and flirting and all that good stuff to have less tension in the group, not more."

"Who's flirting?" snapped Karin. Kate could tell she was feeling defensive and the slightest thing would set her off.

"Not you, Karin. I know you didn't mean anything by it other than a massage. I'm talking more to the younger ladies here. That wasn't nice the way you were teasing Chad about Kevin while Karin was trying to use him to relax. Don't you know not to get between a high status bonobo and the guy that's grooming her? I thought we were all primatologists here."

Everyone laughed, including Karin.

"And don't even try to tell me that Elise's little party today wasn't meant to make Chad crazy with jealousy. Look Jess," Kate continued, "I know I said you could have sex with Chad every night but maybe you're going to have to share him. It seems like he's the hottest male in the group and we could all use some of that, I mean, it seems like all of you could. Not you, Karin. Sorry."

"What do you mean share him?" asked Jess, almost pouting.

"I don't know! Think like a bonobo sweetie! Make a schedule or something with the other girls. Just make sure to leave time for a nice long massage for Karin every once in a while."

They all laughed again. The tension had lifted by now and when Kate looked outside she noticed that the sky was clearing a little and the rain had stopped, though it looked like it would start again soon.

"I don't know, Kate," Jess laughed. "You don't know what that boy can do to a girl, but Ellen and Courtney sure do. I'm kind of used to it by now, to tell the truth, and I don't know if can go a day or two without it. Maybe I'll have to start throwing some 'Chad parties' over here so the other girls can get a little of that fat cock too and I won't have to miss out."

Courtney and Ellen were practically wetting themselves they were laughing so hard and Karin had her legs crossed and was biting her lip.

"Whatever you need to do Jess," Kate rolled her eyes and laughed. "I'm sure you'll be very discrete."

She turned to Karin. "Take a walk with me before the rain starts again."

Karin stood up and they walked slowly down to the lake and then sat down under a little thatched cabana by the shore. Kate turned toward her and looked at her seriously.

"What was going on back there, Karin? Why'd you lose it with Jess like that? And, no offense, but what was all that flirting with Chad about?"

Karin started talking and pretty soon it was all flooding out. She told Kate that she didn't know Chad was going to be on the trip and she wished he wasn't because it was creating real problems for her. It turned out that a few months before the trip, while they were stressed out with planning the wedding and everything, Karin's fiancé Rick had sat her down and had a serious talk with her. He was a psychologist and he had a piece of advice for her that was going to sound crazy at first but she should think about it seriously and she should talk with him about it openly. He'd had so many female clients who get married too young, before they'd sown their wild oats, sexually speaking, and so many of them ended up obsessed with the idea of cheating with another man, and most of them ended up doing it in the end and feeling awful about themselves and maybe even ruining their marriages. He just loved Karin so much and he knew she'd only been with a couple of guys before him, and that was in high school so it barely counted, and he didn't want her to end up going through what so many of his female clients did. He loved her too much. He thought she should think about having a fling or two, discretely, before they tied the knot and committed to each other exclusively for the rest of their lives. He didn't want to have a fling himself because he was much more experienced than her sexually and she was the only woman for him. But he would understand if she wanted to.

Karin was horrified at first and hurt and angry, but then she saw it as part of what she loved so much about her future husband: his understanding and sensitivity and his refusal to be constrained by conventional morals and ideas about how to be a real man. They got a little buzzed one night and ended up making a bucket list of guys she had permission to sleep with before the wedding this summer. It was mostly celebrities and sports stars (Roger Federer was near the top of the list) but there was one "real" guy on it, a hot soccer player from Karin's lab section. Chad Berwick. Her fiancé had loved it when she described Chad to him—his lean body and long dark bangs that swept down over his deep blue eyes. And he'd loved it even more when she played along with him and pretended that she'd been fantasizing about him for weeks, and that she could barely keep her hands off him during those long boring lab sessions, or when he visited her office hours and the two of them were alone in the little grad student office that used to be a broom closet.

They had phenomenal sex that night and Rick ended up cumming inside her so hard that she came too. She'd never done that before from penetration alone. It was so hot because they'd gotten so excited and worked up that she'd forgotten about birth control entirely. She'd just gone off the pill and was using her diaphragm again, which felt much better than a condom but which she wasn't completely crazy about truth be told. The pill fucked you up, sure, but there was nothing better than raw sex with a hard naked cock and a stiff shot of cum straight up inside you. She'd been having vivid fantasies about Chad fucking her bareback ever since then, practically every night. She was horrified when she realized he was on the trip and that they'd be working and living closely with each other for a whole month. In a way she kind of had "official" permission to fuck him, though her fiancé had no idea he was here, and in a way Karin really wanted to.

"So do I," said Kate, "and I've been fantasizing about him too, ever since I heard him back at the hotel."

Karin gaped at her.

"Don't worry about Brian," she added, reading Karin's thoughts. "He's been screwing Elise for god knows how long now."

"I know," said Karin, her face white.

It was Kate's turn to gape now.

"I'm sorry, Kate. I caught them in his office one day and I wanted to tell you, but Brian said that it would just hurt you for no reason and that if I did tell he had ways of making things difficult for me."

Kate shook her head. She wasn't mad at Karin at all, poor thing. That bastard! That patriarchal shit!

"Listen Karin, I think you should do it. I think your fiancé is right. I think he's left the door open for you and you should just walk right through it. And I think you'll be stronger for it and your marriage will be stronger too."

Karin nodded her head. "Maybe. I don't know. What about you? Are you going to do it?"

Kate shook her head. "No, sweetie, that door has closed for me. I'm on the tenure track and I could get in serious trouble for having sex with a student. And I'm already married. And unlike Brian that actually means something to me."

The rain was starting up again and the two women stood up and walked slowly back to the cottage. Courtney had gone back to the bunkhouse and Chad, Ellen and Jess were sitting cross-legged on the floor and passing around a big fat joint. It smelled fantastic. They offered it to Kate and Karin but both women excused themselves and went to their tiny bedrooms. It wasn't late but it had been a long day and both of them were tired.
