Ok, I'm going to set this up in stages. In every new stage the participants will shift groups. Let's start with Ashley, Jack, and Miranda.

"Huh, this place is nicer looking that I thought," Jack said as they all entered.

The Suite they were using had three beds in the main room as well as couches all around each bed for if other occupants wished to view their fellows as they engaged in various activities. It also came with a fully stocked bar, fridge, kitchen, and movie cabinet incase the tired occupants wanted to take a break but stay in the mood.

Ashley let out a sigh and began undressing, "Let's get this party started."

Miranda seductively walked over to her, "Don't be like that. We'll be gentle with you."

"So Miri, you want her pussy or her ass?" Jack asked, sliding off her pants, revealing that she already had a fake cock ready to go.

Miranda made a show of thinking before, "Pussy," she said, stripping and laying on the bed and inserting a cock.

Ashley groaned but got on the bed and crawled over Miranda who instantly began massaging her breasts and toying with her clit. Ashley moaned in pleasure as Jack watched for a few minutes.

As Ashley became more relaxed and Miranda distracted her with her mouth, Miranda lined the tip of the cock with Ashley's pussy before slowly sliding it in. Ashley let out a sharp moan of pleasure as Miranda started a slow rhythm of sliding it in and out of her, "Hm you're nice and tight."

That's when Jack crawled onto the bed and put a hand just above Ashley's ass, "I bet, but I'm also betting that she'll be tighter back here," she said, running her handover Miranda's cock then stroking her own to get it wet, "Did anyone get some lube?"

Liara walked over, "Here," she said handing Jack some lube while looking at Shepard and Kelly who were on one of the other beds.

Jack squeezed some lube onto her hand then rubbed it over the cock and over Ashley's ass. When she was done she lined up and…

"AAAAAHHHHHH," Ashley yelled as the cock slid into her, slowly entering until Jack had the entire shaft buried in her.

It took a few moments but eventually Jack and Miranda got their rhythms synced so that one was entering as the other was pulling out.

As they did this Ashley could feel her orgasm building. Miranda was the first to cum, she let out a moan as she thrusted as deep as she could, cum still managing to squirt out of Ashley's pussy from around the cock. Jack was next, she to buried herself as deep as she could. And then finally Ashley, who was driven over by the feeling of the cum being sprayed into her ass.

As Jack pulled out Liara walked up to her with some paper towels which Jack used to clean her cock off with while Ashley collapsed on top of Miranda as they came down off the orgasmic high.

"Ha, pussies. First orgasm of the night and already they need a break," she said to Liara.

Ashley slowly got up, pulled herself from around Miranda's cock, and made her way to the bathroom. Trying not to let the cum leak out of her ass as she walked.

"Where're you going?" Jack asked.

"To empty my ass."

Meanwhile.

As Miranda was starting with Ashley, Kelly had undressed and was laying on one of the other beds, nervously covering herself up out of embarrassment.

"Kelly," Shepard said softly, "You don't need to do this," Shepard said, giving Kelly one last opportunity to back out.

"I said I would. And if you let ME back out of a promise then you would have to let everyone. Besides," she said, a deep blush forming on her face, "I want to be able to please Tali when we eventually want to take our relationship further."

Shepard smiled, "Then I'll do my best to take this slow for your first time," she said pulling Kelly close, and softly caressing her to help her relax. When Liara came over with the lube Shepard applied it to herself then continued to softly caress Kelly while applying it to her.

When she thought she was ready Shepard slowly slid into Kelly, feeling her instinctively tighten around her before loosening as she continued, watching her as she did for any hints of pain. Once she was completely buried she began to move in and out in a slow rhythm, wanting Kelly to enjoy the pleasure of her first time.

As she did Kelly had a constant stream of moans and gasps of pleasure flowing from her mouth. When they heard Ashley, Miranda, and Jack having their orgasm Shepard angled herself so that she would press against Kelly's g-spot as she entered. This caused Kelly's breath to hitch as the new pleasure hit her.

As Shepard heard Ashley comment about needing to empty her ass, she started to move quicker until finally Kelly climaxed and came so hard that it drove Shepard into an orgasm.

For the next twenty or so minutes Shepard held Kelly as she had her first orgasm. Nobody complained, knowing that she, having been a virgin, would need a few minutes. "Miranda," Shepard said.

"Yeah Shepard."

"You are to go slow and let her take her time, because if you hurt her, even accidently, I'll-"

"Whoa, calm down Shepard I was planning on being gentle. I know how to use my biotics to cause a calming orgasm as well as an awesome intense one."

"Calming orgasm?" Liara asked.

"Instead of giving a serious rush, you feel yourself relax. It works great if you feel stressed and think that normal sex won't calm you down."

"Ok then, give her a few minutes then begin," Shepard said as Kelly relaxed enough to let go of her.

"I call being with Liara first!" Ashley called out.

"Damn it!" Shepard yelled playfully.

Liara just smiled and walked over to where Ashley was now laying, a fake cock standing erect at the sight of her naked form coming towards her. As she crawled onto the bed Shepard walked over to Jack while Miranda held Kelly till she finished calming down from the first orgasm.

As Liara reached Ashley the brunet pulled her into a deep kiss while closing the space between their bodies, the cock pressing into Liara's stomach making them both moan. As their nipples rubbing against each other Ashley reached up to pinch and toy with Liara's eliciting a moan from the blue skinned beauty.

Ashley then suddenly flipped them around so that Liara was below her before thrusting into her getting a very audible moan from the Asari.

As she started a steady rhythm she nibbled on Liara's pulse point in her neck. Liara then initiated a simple meld, not enough to share thoughts, but enough to share the pleasure she was feeling. Ashley smiled as she felt Liara's mind mix with hers and as the added feeling of pleasure entered her mind.

For a while Ashley just enjoyed the feeling of Liara's mind connected to hers before finally she felt Liara climax and take her over the edge with her.

Shepard watched as Jack removed the fake cock, the sight making the one she wore throb so badly it hurt.

Jack walked over and was about to straddle her but Shepard held up her hand, "Before you get this," Shepard said, pointing to the cock, "You're going to have to clean it."

Jack smiled lewdly at her before settling on her knees and grabbing the cock with her hand. Shepard grunted, but before she could say anything Jack had her mouth around the cock and was half way down its length before she could say anything.

As Jack slid it in and out of her mouth she kept taking more and more of it with each plunge till she was taking the full twelve inch length of it each time.

As Jack continued to suck Shepard was having a hard time not just grabbing her head and trying to thrust her further down the cock.

When she finally came she did pull Jack's head down so that all the cum that spurted out the tip went right down her throat and into her stomach.

As Jack pulled away from Shepard she gave her a raised eyebrow before climbing onto the bed and while her ass pointed towards Shepard, "Since you seem to want to act like an animal, why don't you fuck me like one," she said.

No sooner had she said this that Shepard had stood up, turned around, grabbed her by the hips, pulled her towards her, right onto the full length her waiting cock, her ass colliding with Shepard's hips with a very audible smack.

Shepard then proceeded to roughly slide in and out of her eliciting a great number of moans from the tattooed woman. As she continued to do this she could feel Jack tighten a little around her while her moans almost started to sound like a feral grunting sound.

Then as she came she held onto Jack's ass so hard she knew there would be a few bruises where her fingers were in the morning.

Meanwhile Miranda was deciding how to begin with Kelly, "Ok, do you think you're ready?" she asked. When she received a nod she laid Kelly onto a mound of pillows before slowly and carefully sliding into her.

Once she was in as far as she could go she charged up her biotics before sending a pulse through her cock into Kelly. As it entered the orange haired woman she let out a soft gasp followed by a soft moan.

Miranda pulled out a little before slowly sliding back in, releasing another pulse as her clit touched Kelly's. She repeated this, going slow and taking her time much like Shepard had until Kelly said, "Hey Miranda, could you go a little rougher?"

Miranda looked at her, "What do you mean?"

"I mean, could you pull out a little more, slide in a little harder, and release a little more energy each time?"

"Uhm, ok," Miranda said. She had been pulling an inch out each time, but she started to pullout two inches and push in about twice as hard as she had been.

After about a minute of this she went to three inches, then to four, then five until she was pulling completely out then pushing in about as roughly as Shepard was to Jack, who sounded more like a growling bear.

And with each time she shoved in she released more and more biotic energy. By now the energy was lighting her up, and it was also beginning to glow around Kelly as well.

As she heard Jack and Shepard finish their doggy style sex, though it was hard as Kelly was now moaning quite loudly, she looked over to see the two of them staring at her and Kelly. She glanced at Ashley and Liara to see that they were staring also.

Kelly noticed Miranda slow down because she yelled, "Hey… fucking… pay attention… to what you're doing!"

Jack turned to Shepard, "Does she swear often?"

"This is the first time I've heard her," Shepard said, pulling out of Jack, both of them joining Ashley and Liara on the couch that surrounded the third bed.

Meanwhile Miranda was going crazy. She could feel Kelly soaking up each pulse of biotic energy and somehow using it to stimulate her cock enough to cause shitloads of pleasure, but it was also keeping her from having an orgasm.

Kelly then surprised her by flipping them over so that she was on top, then saying, "Jack… plug in, and get up here."

Shepard felt her jaw drop. Her sister Kelly, who blushed at the mere mentioning of sex, was riding Miranda like there was no tomorrow, AND she wanted Jack to do a double penetration.

Jack stood up, inserted a cock, climbed on the bed, and then charged her biotics as she pocked the tip of the cock into Kelly's ass.

Kelly howled in pleasure after the initial pain subsided as Jack inched her way in. Once she was in all the way she let out a pulse then, in sync with Miranda starts pumping in and out releasing a pulse as she she's completely in.

Even through just the tips of their cocks Jack and Miranda could feel the others pulse travel through the pseudo extensions and into them, causing as much bliss as they did Kelly.

After another ten minutes both Jack and Miranda had realized that Kelly was somehow keeping them just at the edge of an orgasm. As they stop to breath Jack says, "Damn Shepard, how's she keeping us from going over? I mean she's using our own biotics against us here. Any ideas?"

"She has very weak biotics. Not enough to throw a something but enough to keep bugs off of her with a weak barrier. She must be-"

"I was using them to manipulate your biotics to get the most out of this, but now they won't stop. And I really want to cum," Kelly whined from the over stimulation and lack of result.

That's when Liara stood, "I may have the solution," she said slipping in a blue cock, "But if you want it," she began, getting on her knee's in front of Kelly, the now erect cock inched from her face, "You're going to have to work for it," she said before slipping it into Kelly's mouth.

As Jack and Miranda started back up Liara began pumping into Kelly's mouth, and again Kelly's biotics making Liara begin sending out pulses.

Now with the three of them combined the pleasure was unbearably strong.

Once Liara felt herself reach the same edge of a climax as Jack and Miranda, she initiated a meld. And that was all it took.

All at once Jack, Miranda, and Liara came into Kelly, filling her with so much cum, Jack was surprised that her stomach didn't burst. While Kelly had an orgasm so strong she was surprised her heart didn't stop.

Meanwhile the couches surrounding the bed were blast backwards, along with Shepard and Ashley, by the release of the pent up biotic energy, as Jack, Miranda, and Liara and breathed heavily they all pulled out of poor Kelly who had passed out, much to Shepard's shock and horror.

"She's alright Shepard. Though she may be out for a while, that was a very big orgasm," Liara said.

"Ok, no more using biotics on Kelly," Shepard said, cradling her sister in her arms, scared that she had allowed it to go too far, "I'm going to sit with her on the couch, you four clean up the couches then enjoy yourselves without me for a while.
