Tanner was sitting alone in the dark when the door to his room opened. He’d almost expected it and wasn’t surprised at all when Grace opened his door and stepped inside. There was something about sex, it had gone from something odd and mysterous in his life to almost common place. Once he broached the topic with a woman they seemed oddly drawn to him. He didn’t know whether it was curiosity, novelty, or what, but talking about his system just skipped past all the awkward feeling around that most starting relationships always seemed to have. They knew what he had and the relationship could then move on to whether or not they might be interested in it.

 

With Grace he had a pretty good idea. It was part curiosity, part teenage hormones, and part being heartsick and wanting to feel the touch of another person. Tanner felt exactly the same way. Back in his pre-system days he’d have never thought of sleeping with a girl like Grace. She was homely, stocky, and had a stronger jaw than he did. After fighting with her though he realized how much of a fucking moron he’d been.

 

She was quiet, solid, strong, and literally had his back in the biggest cluster fuck he’d ever been in. That trumped looks 100 times out of 100. As usual she didn’t say anything. She just started pulling off her clothes. He hadn’t noticed it before but she did have rather nice breasts. They were heavy C’s, maybe even pushing D but they sat high on her chest, only sagging lightly with their own heft. She had broad shoulders for a woman and her whole body spoke of power. She didn’t quite have a six-pack but she had the better part of four. That turned him on for some reason.

 

Tanner undressed himself and went to her. When he tried to pull her into a hug she just shoved him back onto the bed with one arm. He practically flew backwards and bounced. The girl must have at least 15 strength. She came up and straddled him looking down at his growing erection. Her eyes did widen a bit then and Tanner couldn’t help but smirk. 

 

He hadn’t actually measured it since the last upgrade but he’d done the math during a weaker moment after the first upgrade. The first upgrade had put him right around 7 inches. Extrapolating from that, He should be right about at 9, or 8.8 or something. It was massive compared to what he’d been used to all his life and he noticed Grace went slowly as she pointed him to her core and lowered herself down.

 

She was so tight… He’d been with a few women now and they all felt subtly different. Grace seemed to be trying to forcefully wring his sperm out of him. He gasped and she smiled down at him. It was incredible and made her plain face into something amazing. Not pretty or beautiful but powerful and alluring all the same. Then she squeezed her inner muscles and almost broke his dick off.

 

It was actually painful but it also sent even more blood to his cock as if it refused to be cowed. Tanner was done being a passenger. He triggered his lust aura just to add some icing to the cake and leaned up to get at her with his mouth. She didn’t bend down for him and with her height being nearly equal to his he couldn’t kiss her but he could reach her nipples which he was more than happy to take as a substitute for her lips.

 

She gasped and clamped down on him again. That was when his Sexual Empathy informed him that Grace LOVED having her breasts sucked on. Tanner was more than happy to oblige. He nursed from her and she rode him at the same slow and steady pace. Time seemed to drag out as they pleasured each other, both gasping from the joy of it and clinging to each other and they reveled in being alive and together. 

 

He wasn’t sure how long it lasted but they both seemed to know that this one moment was too precious to break just by coming. They went on and on in the same slow motion. They had to go at least a half-hour like that, each trying to drag things out just a moment longer but eventually all things must end and she let out a low groan as she clamped down on him and shuddered in release. Her pussy and thighs squeezed him so tightly he actually couldn’t breathe but the asphyxiation just made him cum harder and they clung to each other as they both shook. 

 

Tanner slumped over exhausted and gasping for breath when she finally released him. They fell asleep in each other's arms but she was gone when he woke up.

 

***************************************

 

When Tanner woke up Thursday morning he felt god-like. His level 1 buffs had been like a good night's sleep, a massage, a shot of red-bull, and a self-help video. His level 5 buffs were like a week's vacation, that weird blood-doping thing all the Tour-de-France guys used to do, and some kind of supernatural mega coffee.

 

More than his body though was his mind. The world seemed more in focus as if he could sense the subtle connections between everything around him. His depression from the day before was gone as well. The grief was still there. His heart still hurt from the losses and the ugliness he’d seen but it was tempered with perspective. Yes, people had died, but they’d died for a good cause. That was something that few people ever got to do.

 

So he took a shower got dressed and went for a jog. It seemed a bit silly after all the complaining he’d done about the constant running, but he really was sick of humping a full pack for 10 miles every damn day. He did a single lap of the base at a light-jog. It was exactly three miles and Tanner finished it in about 20 minutes feeling ready to take on the day. He breathed in the cold air and brought up his system.

Congratulations! You’ve Earned System Points

Encounter Rating B+ Sex is the most powerful celebration of life. It is shared joy, shared pleasure, and the absolute certainty that neither you nor your partner is alone. You have shared this boon with another and both of you are better for it. Sp Earned: 2,250 750(B+ Base) x 1.5(Level 5 System) x 2(High Stress)

Tanner thought he was finally getting a handle on his system. Maybe it was the mental buff he had going but he was pretty sure he’d cracked the code, at least in terms of scoring. A ‘B’ was when he took his partners sexual needs into account and did his best to fulfill them. It meant he’d done his job well as a lover and that she’d gone away fully satisfied. A ‘C’ was something obviously worse than that, an enjoyable encounter but one that left his lover at least somewhat disappointed, likely because of something he’d done or hadn’t done that she hadn’t really enjoyed.

 

‘B’ seemed to be the highest grade he could get for a purely physical encounter. To score higher he had to touch on something deeper. Last night had been the best sexual experience of his life. In terms of pure erotisicm and pleasue Marcela’s blowjob had been one notch higher, but that hadn’t held a candle to the oneness he’d felt with Grace. It had been more than just sex. They’d shared something precious. 

 

That extra emotion and connection was what he needed to score higher than a B, but he realized that such encounters were destined to be highly situational. Last night they’d both been hurting emotionally and they’d used sex as a bridge to comfort each other, as well as solidify the bond they’d created while fighting back to back.

 

His only ‘A’ ranked encounter had been another thing altogether. There the sex had been almost ancillary. He blinked at his mental use of the word ancillary and wondered just how buffed his mental buff actually was, but his hyper focused mind didn’t let the thought distract him long. Yes, that had been all about Marcela, and the sex had been more medicine than pleasure and it had only been so powerful because of how wounded she was in heart and mind.

 

Tanner likened it to a married couple who loved each other. Regardless of how deep their feelings and love were, every single time they had sex couldn’t be a deep soulful love making, nor should they try to make it that.

 

Tanner promised himself that the next time Grace or Marcela came over he wasn’t going to try and make things too complicated. He was just going to fuck the daylights out of them and see if he could find out what their ahegao faces looked like. 

 

He had earned a good bit of points both with the fighting and the sex but he still couldn’t get to level 6. He’d passed the stage where he could jump levels easily. He did have enough points to upgrade either his Size Does Matter or his Sexual Empathy though. The problem was he didn’t really feel like he needed either ability.

 

He didn’t feel like gaining another two inches to his penis would be particularly valuable.  Yes, it would be an ego boost, and likely make his orgasms even more pleasurable for him but at 11+ inches and as wide as he’d likely be the mechanics of sex would be awkward for a lot of women. He couldn’t imagine trying to have sex with Grace with a larger penis. He doubted he’d have fit at all without a great deal of coaxing and effort and even if he did it would likely have been painful for her, at least at the start.

 

On the other hand his ultra logical brain was telling that rank 3 was likely the max rank of Size Does Matter, so buying it would likely add a powerful effect to it, or unlock something else within his system.

 

Sexual Empathy didn’t really seem all the useful either. He felt pretty confident that he could scrape a ‘B’ with almost any woman at this point. So thinking pragmatically, he didn’t need more understanding of their sexual wants. Granted, he liked the women he was having sex with and bringing them more pleasure was high on his list. He would buy all these abilities at some-point but he just didn’t know what to do right now. 

 

The final and most relevant argument was that saving his points to hit level six ASAP would give him more stats and in a war zone more stats could very well save his life. He didn’t dither for long and by the time he’d made it back to his room he’d decided to be illogical. He grabbed rank 2 of Sexual Empathy. If his goal was to see an ahegao then he needed all the help he could get. Silly and juvenile yes… but he was an eighteen year old guy with a sex system.

 

Weapons training that day was a breeze. Tanner felt like he’d learned a week's worth of lessons in the two hour class and even seeing so many missing faces hadn’t been able to put too much damper on his mood. The sparring had been worse since all his normal partners were dead. He’d been forced to fight a short asian girl who’d completely dominated him with a bokken and a skill level with her weapon he was nowhere close to matching. The only thing that made it alright was seeing Grace again and getting a small smile from her.

 

Even with the somber mood, it had still been one of his best days on the base and things got better when Marcella knocked on his door that evening. She was wearing her uniform but her bad arm was in a sling. She smiled when she saw him and Tanner got up from his small desk. He’d been reading an Ebook on his phone but he quickly sat it down before he walked over to pull her into his arms. They kissed hungrily.

 

“I’ve been looking forward to this all week.” She said with a purr. She seemed eager to move things along but Tanner was content to take his time. He had a whole list of things he planned on doing to her and he wasn’t letting her off the hook tonight until she was a blissed out wreck. 

 

He helped her out of her coat and ran his hands all over her as they kissed and pawed at each other, giggling like teenagers in the back of a car. Finally she got her shirt off, and Tanner found out she hadn’t bothered with a bra. He cupped her breasts with reverence. He hadn’t even managed to get her bra off last time but she had excellent breasts with small dark nipples and he couldn’t help but give them a soft pinch as they continued making out.

 

Tanner shoved one hand down into the waistband of her pants and discovered she skipped the underwear both top and bottom. He growled as his lust surged up and he pushed her down onto the bed and yanked off her pants.

 

She let out a low throaty laugh and Tanner spread her open and put his mouth onto her core. Unlike the first time he’d tried this on Janel he didn’t try to get her off as quickly as possible. Instead he licked, nibbled, and sucked on her inner folds and outer lips until she was a moaning mess.

 

“Tanner!” She cried out and grabbed his hair with her good hand. He pulled away from her center and kissed and bit at her inner thighs as he groped her breasts with his hands. She let out an animal growl of frustration as her oncoming orgasm faded away and Tanner went back to her center, driving her to an even higher plateau. 

 

The second time she didn’t let him pull away and mashed his face into her pussy with her superhuman strength. He grinned into her as she fell over the edge bucking and thrashing. Tanner stood up from his knees and took a moment to enjoy the view before stepping down to the floor and dragging her to the edge of the bed.

 

He pushed her knees up to her shoulders before entering her in a slow thrust. He made sure the angle had him hitting her G-spot on every entry and fucked her silly. He pounded her like that until sweat was running down Tanner’s face and Marecla was making some very unladylike grunts but she felt so damn good.

 

Tanner straightened her legs and when his hands grabbed her feet he got some very interesting feedback from his Sexual Empathy. It seemed Specialist Morales had a foot fetish. Well, maybe fetish was the wrong word but she really wanted her feet licked. That was pretty bizarre but he could oblige, she did have great legs, so he started running kisses up her calves as he kept pushing into her.

 

The closer his lips got to her feet the louder her grunts got and he slowed his thrusts to keep her from coming. He ran his tongue over her toes and she let out a pitiful moan as she thrust against him. He kept it steady until she was on the edge again then sucked her big toe into his mouth. 

 

Marcella didn’t so much cum, as explode. Her whole body seized up and she squirted all over his chest and face. Tanner didn’t actually know that could happen. He’d always thought squirting was a porn gimmick but apparently not. As strong as she was, he had a hell of time continuing as she came, but he did his best, plowing into her and he kept sucking her toe. Her orgasm went on and on until he joined her. Just as he started to release one especially violent contraction of her legs kicked him in the face with the foot he wasn’t sucking on. He fell backwards onto the floor, cum still shooting from his penis and covered in Marcella’s juices. Tanner just lay there laughing as he came down from his climax. 

 

Eventually he picked himself off the floor covered sex fliuds and feeling like he’d gone above and beyond. Marcela was curled up in a ball, her body covered in sweat and still twitching occasionally as she tried to catch her breath. 

 

“What the hell was that?” She said once she’d caught her breath and her body had stopped spasming.

 

“You squirted… Then kicked me in the face.” Tanner said, still grinning.

 

“Not that… I’ve never come that hard in my life. I thought I was going to die.” She snapped at him.

 

“You apparently really wanted your toe sucked on.” Tanner said with a grin.

 

“You didn’t use some sex ability on me?”

 

“I don’t  have any ability like that. I can make you more horny and I can get a feel for what you’ll enjoy…...No, that was all you.” He said.

 

“Demons…… I didn’t know that would feel so good. I mean, yeah I’ve always enjoyed a foot massage but I’ve never had anyone lick my feet before.” She said, wide-eyed.

 

Tanner grinned, he seemed to be doing that a lot tonight, and turned on his Lust Aura. “Well, Specialist, you better brace yourself because we aren’t nearly done yet.”

 

He had her three more times before exhaustion and pleasure drove them both to sleep, then once more when she’d woken him up sometime before dawn with another blow-job. Tanner had pulled her hips around and engaged in his first 69. He’d always wondered what the big deal was, as the number was always the punch-line of adolescent joking, but having her amazing brown ass on his face while his cock was in her mouth was definitely going on his list of favorites.
