"Uhh, yes, keep doing that." Ashley groaned, she was laying on the bed as Shepard went down on her, one hand resting on his head. Her other hand was currently massaging her newly enhanced, latex-clad breasts, the rubber squeaking as she ran her hand over it.
Ashley was dressed in a pink latex catsuit, with leather thigh-high boots and shoulder-length gloves. If she thought the latex suit was a pain to get into before, it was even more difficult with her new tits. Easily filling more than one of Shepard's hands, and even spilling out to the sides despite being fake, her new breasts required fully custom-made suits. With two people pulling and lots of silicone lube, they eventually got the suit over her thick ass and wide hips, and were soon pulling the latex over her augmented chest, squeezing them tightly together creating a push-up effect which made them look even bigger. The zipper went up her back and she was now fully enclosed in smooth, shiny rubber clinging to every curve. The light from the LEDs and simulated fireplace in their apartment bouncing off the gleaming pink suit.

"Oh, skipper, don't stop." Ashley moaned, as Shepard was running his tongue in and around her netherlips, his left arm around her plump thigh while his right hand was caressing the subtle curve of her sleek stomach, abs just visible underneath the latex. He loved the feel of the rubber against her body. Ashley had her legs over his shoulders, her left boot heel on his back keeping him from moving, his right ear against her thigh. He could just barely see her face over her huge enhanced tits, most of what he saw was just latex straining as her chest stretched it, the suit creasing around the sides of her torso.

Shepard started fingering her, causing Ashley to gasp and grasp at the bed covers.
"Oh! God, keep going!" He was hitting all the right places, making Ashley push him harder inbetween her thighs, her boot pressing firmly in his back, as he pushed her further towards climax. As her body got more and more worked up the closer she got to her peak, the more she started to sweat underneath the tight and non-breathing latex. That combined with the lube required to put it on caused the suit to drift slightly upwards as she made involuntary thrusting motions with her hips when Shepard hit especially sensitive parts inside her. The area around the tops of her thighs and groin was starting to crease a bit more.
To further her own pleasure and climb to the top, Ashley started massaging both of her breasts as Shepard continued working overtime. She loved how huge they felt in her hands compared to her old size, and had zero regrets about getting them improved. They were worth every single credit. The fact that there were implants beneath her hands only turned her on even more, as her massage almost turned into groping. The sound of the rubber as she pinched her nipples through the suit was just the sugar on top.

Shepard watched as she squeezed her own boobs and he still almost couldn't believe she went through with it. He loved her somewhat small, natural breasts, but her new ones were just incredible. The comparably massive size increase, the not-quite-natural roundness, their firmness, all while still being soft and jiggly like before. Modern medicine was quite something. Even if medical technology had progressed to the point where actual implants weren't always needed, stem cell therapy didn't allow for as direct control over shape and took a lot longer to come to fruition, genetic engineering even more so at several years before results show. It's why Systems Alliance soldiers, like Shepard and Ashley, got gene enhancements as recruits, and it was also why Ashley chose to get implants. She wanted them as soon as possible.

Shepard continued to quietly lick and finger her, moving his left hand from her thigh to her stomach to keep her hips from jerking too much as she made her climb to the top, quickly approaching climax.
"Yes, yes, yes, keep going, keep going!" He saw and felt her abs clenching and unclenching under the latex, Ashley's breathing getting even quicker, the rubber covering her enhanced tits creaking as she arched her back and put both hands on the bed to steady herself, her goal being just around the corner. Her moaning become more constant.
As Shepard made a come-hither motion with his two fingers and paid extra attention to her clit, she finally came. Her muscles locked up, both legs pushing him in, toes curling, hips jerking, hands involuntarily grabbing the bedcovers hard, lungs stopping. A silent scream and squeezing her eyes shut, then came the loudest moan yet. Husky and low, her body suddenly released all the tension and she fell to the bed. Her hair was a mess and stuck to her sweaty forehead, her large boobs jiggled as she impacted, and her abdomen and groin continued twitching.
Shepard moved both his hands to Ashley's thick and soft latex-clad ass as she came down from her high, gently licking her as the aftershocks levelled off and her breathing stabled, a big smile on her face and softly shutting her eyes this time.
"Oh, skipper, that was amazing." He took the time to squeeze her butt, he hadn't gotten a chance to while her keeping her hips in control.

As Ashley started to calm down, Shepard started kissing his way up her body. From her mound, up her smooth stomach, to her large breasts, then her neck, and finally her soft and full lips. Those were natural and all hers. Ashley put her latex-covered hands on his cheeks as they started kissing.

Of course, Shepard was as hard as he's ever been, so the night certainly wasn't over yet.
