THREESOME!!!

John smiled against Riley’s breast. He gave her nipple one last gentle bite, then sat up. “Having fun?” He asked with a grin. Riley grinned back at him, then removed her hand from her sex and held it up in front of John’s face, her fingers glistening with her cum.

“You tell me.”

John inhaled the sent of her juices, the took hold of her wrist and guided her hand into his mouth, licking off all of her sweet nectar. Then he leaned down and kissed her. He was about to deepen the kiss when Riley gently pushed him away. “What about Cameron,” she asked. John turned his head and looked at the cyborg. She was standing by the doorway with her head tilted to the side. She looked, curious. Riley reached up and cupped John’s cheek, turning his head so he was looking down at her again. “Don’t you think we should ask her to join us?”

John quickly looked at Cameron again. He had to admit, he found her very attractive. In fact, for the most part he thought she was hotter than Riley, not that Riley wasn’t hot. Her main drawback was that her breasts were smaller, though John supposed that Riley’s larger tits would look out of place on Cameron’s petite dancer’s body. And the fact that Riley was actually asking to have a threesome... But, Cameron was supposed to be his, sister. And while Riley was certainly unconventional, John could easily see her being bisexual, he found it hard to believe that she would go as far as ****. Maybe she had just forgotten in the heat of the moment.

“Ah, Riley, she is sort of...” John trailed off, hoping Riley would get the message.

Riley could have kicked herself. She had completely forgotten that the metal was pretending to be John’s sister. Which Riley supposed wasn’t that surprising, when ever she thought about Cameron, she was usually ether worrying about whether the machine was going to kill her, or thinking about what she would be like in bed. This didn’t leave much room for insignificant details.

But no, having the two of them at the same time was one of her greatest fantasies, and Riley would be damned if she was going to let it slip away. The two of them weren’t really related, the only reason John was bringing it up was because she, Riley, was supposed to think they were. There must be some way to get him to go with it.

Strangely enough, Cameron’s thoughts greatly mirrored Riley’s. This was the closest she had come to experiencing sex with John in, ever. And while Riley wasn’t Sarah Connor, she would certainly do. The thing was, while Cameron had been built to be able to experience and enjoy sex just as any human female would, and Skynet had no doubt tested those systems when it built her, thanks to the reprograming the resistance had given her she had no memory of this. So while she was capable of it, Cameron had no idea what sex was like. A shortcoming she desperately wanted to rectify.

Cameron had wanted to have sex with future John, but she had known that he was far too faithful to his own wife to ever go behind her back. Certainly not with a machine. And of course none of the resistance soldiers would have ever even considered sleeping with her. And while she was sure this John was attracted to her, there always seemed to be to many obstacles to pursuing any kind of sexual relationship with him. Cameron had considered letting Morris, ‘fuck her’, but decided that she wanted her first time to be with John.

However with Riley present they had to maintain the pretense of being brother and sister, and according to human costumes it would therefore be prohibited for them to be sexual involved with one another. Unless...

While both John and Riley quickly tried to think of a way around this problem before the situation became to awkward, Cameron stepped forward. “John,” she said, “I’m adopted, remember. Your mother adopted me when I was thirteen. So we’re not actually related. Which means it’s okay for us to have sex,” Admittedly, even Cameron knew that this was a bit of a stretch, but as long as Riley went for it...

Riley grinned up at John. “You two aren’t related? Then what are you waiting for?” Trust a machine to come up with a logical solution to a problem. Riley would have to remember to thank the other girl, thought the way things were going that probably wouldn’t be to hard.

John returned his girlfriends smile. He gave her a brief kiss, then straightened and turned to face Cameron. He walked over to her so that they were standing right in front of each other, then he put his hands on her jean clad hips, drawing her closer so that there bodies were almost touching. John slowly slid his hands down around her hips so that they were cupping her tight ass. In doing this he noticed a small problem. In moving his hands he had felt the 9 mm Handgun Cameron had shoved in the back of her pants, and at the same time he became very much aware of his own weapon. Suddenly John had an idea. He squeezed Cameron’s ass, an action which John couldn’t help but notice caused her to let out a small gasp, then moved his right hand up her back to grasp the back of her head. Then he kissed her. After a moment she opened her mouth, allowing John’s tongue to gain entrance. While at first John didn’t find the kiss very impressed as Cameron didn’t know what she was doing, the cyborg quickly began to first copy John’s actions, then come up with her own.

While this was happening John slowly pulled out Cameron’s gun with his left hand and put it in the open dresser drawer that was right behind Cameron. Seeing what he was doing, Cameron turned them around, then did the same with John’s weapon. The kiss continued until John was **** to end it due to a lack of oxygen. He placed his head on her shoulder and and started to massage her firm ass cheeks with both his hands.

Cameron, meanwhile, took the opportunity to review her own responses. There was now a powerful felling in her groin, almost an ache, and her vagina had began to release fluids to act as a lubricant for the penis during sexual intercourse. Also, Cameron noticed that her nipples had hardened despite the fact that she was fully clothed and quite warm. Cameron glanced at the open door to Riley’s room and suddenly became aware of yet another problem.

“Riley,” she said turning her head to look at the blond girl, who was now sitting up against the headboard of her bed and leisurely fingering herself while watching John grope Cameron’s ass. “What about your foster family?”

“They’re all gone. Wont be back until tomorrow afternoon,” Riley said absentmindedly. Then she looked at Cameron. “What, did you think I would lay naked on my bed masturbating with my door wide open if they were around?”

“Of course not,” John muttered before he started to suck on Cameron’s throat. The two of them took several steps back towards Riley’s bed before Cameron reluctantly pushed John away, felling that they were both wearing to much clothing. Cameron removed her customary purple leather jacket and dropped it on the floor before removing John’s black one. Cameron then pulled off John’s shirt, then allowed him to return the favor. John moved his hands up, fingers brushing against the skin covering her ribs, before using them to cover Cameron's breasts. As he moved his thumbs over them he could fell her hard nipples through the fabric of her baby blue silk bra. This caused Cameron to let out an even louder gasp.

As this was happening Riley got off her bed and walked over to stand behind Cameron. She placed her hands on the smooth skin of Cameron’s back, then slid them up to take hold of the clasp that held Cameron’s bra together. She unhooked it, then stepped back. Seeing this John moved his eyes up to lock onto Cameron’s then slid the straps of the garment off of her shoulders and dropped it to the ground. Then he slowly moved his gaze down so that he was staring at her chest. She had milky white breasts, each capped with a hard pink nipple surrounded by a rosy quarter sized aureola. They were on the small side, but perfect. John looked up and saw to his surprise that Cameron was actually blushing slightly.

Riley placed her hands on Cameron’s shoulders and turned her around so that they were facing each other. She pulled the other girl to her, crushing her large breasts against Cameron’s smaller ones, then kissed her. Since Cameron had already gone through this with John she knew what to expect, her tongue dueling expertly with Riley’s. They moved back until Riley came up against the bed, at which point Riley broke away and sat down. She saw to her relief that Cameron was wearing simple slip-on shoes instead of her usual black leather biker boots. in fact, she wasn’t even wearing socks.

“Take off your shoes,” Riley muttered, then while Cameron complied reached out and unsnapped, then unzipped the front of Cameron’s jeans to reveal a thong the same color as her bra. Riley pulled the pants down past Cameron’s hips where they fell down to pool at her now bare feet. As Cameron stepped out of her leggings Riley hooked her fingers in the sides of Cameron’s panties, then as quickly as she could pulled them down. Riley slid her hands up to rest on Cameron’s now bare hips as she gazed at what was as far as she could tell a very anatomically correct snatch. The cyborg’s pussy was completely bare, though as Riley looked closer she saw the tinniest hint of hairs, so she guessed it wasn’t naturally that way. Near the top of her slit, partly covered by a fold of skin, Riley saw a small nub, which she realized must be the girl’s clitoris. Riley took in a deep breath through her nose, reveling in the musky sent of arousal coming from Cameron’s sex.

After a moment Riley looked up at Cameron, who was looking down at her passed the small mounds of her breasts. “Have you ever been with another girl before?” Cameron shook her head. “A boy?” Cameron shook her head again. “Before tonight have you ever masturbated, or done anything of a sexual nature?” Cameron shook her head. “Well then,” Riley said with a grin, “you’re in for a night of surprises!” Then without any warning she grabbed Cameron’s naked ass with both hands, sliding her fingers between the two cheeks and pulling them apart, then pulled her pelvis towards her face, her nose pushing into Cameron’s pubis as she stuck out her tongue and ran it through her folds and over her clitoris before leaning back to see Cameron’s reaction while savoring the taste of her cum.

When Riley’s tongue had touched her snatch Cameron moaned. When it reached her clit the moan turned into a cry. Cameron found that it was all she could do to remain standing as her CPU tried to process all of the sensations she had just experienced. After a moment Cameron realized that she was actually panting, as if she were out of breath. She looked down at Riley, who was grinning up at her lazily. Cameron noticed that the girl’s hands were still clutching her ass.

“Did you like that?” Riley asked. Not yet able to speak, Cameron nodded. “Would you like to continue?”

“In, in a moment,” As much as Cameron liked what had happened, she needed to process all of it before they continued. Doing this would allow her to deal with similar sensations much more easily. Riley stood, her body pressing against Cameron’s, and kissed her. It wasn’t a deep kiss, just a series of quick pecks. Riley moved to Cameron’s jaw, then along the side of her face until she came to the cyborg’s ear. Her tongue licked around it while she sucked the earlobe into her mouth. Cameron turned her head to the side, partly to allow Riley easier access, and partly to see what John was up to.

While Riley had been exploring various parts of Cameron’s body with her mouth, John had been taking off the rest of his clothes. First his boots and socks, then jeans. As Cameron watched he slid off his boxers to reveal his fully erect penis, Cameron estimated it to be 6 and 7/12 inches in length. About an inch thick at the base. He was circumcised, his exposed tip already shining with a drop of precum. John walked over to the two girls and put an arm around Cameron’s waist, drawing her to him. His other hand slid around the back of her neck as he kissed her, there bodies pushed together so that Cameron’s nipples pressed into John’s chest while his cock was pushed up against her lower abdomen.

Riley watched the two of them for a moment, then walked around to come up behind John. She wrapped her arms around the two of them, her breasts flattened against John’s back, and rested her chin on his shoulder. John ended the kiss and just stood there, enjoying the feeling of being sandwiched between two naked female bodies. Riley moved one of her hands between John and Cameron’s bodies so that she could take hold of his swollen member, her thumb caressing the purplish head. John moaned.

“So hot stuff,” Riley whispered in his ear, “it looks like you have a choice to make. Just which one of us are you going to fuck first?”
