Mark jerked his hand away from Sean's, uttering out in complete shock. "What?! What kind of sex did you download?" Sean blinked nonchalantly, replying casually. "The file had a lot of different variations on the matter of sex. I didn't know what you would like. So, I picked randomly. Did I choose wrong?" Mark shifted on the bed to put his back against the cement wall. Pulling his legs up uncomfortably, he stammered out. "I... Look. If I have to have a 'safe word,' then I'm out. You're not going to squeeze my balls with your vice grip... Or whatever. Pick something else." Sean shifted to face him better, coolly responding comfortingly. "What you are saying is focused more for those that like pain to balance pleasure. I picked one more focused on building up sexual desire through stimulation and withdrawal." Mark shook his head defiantly, muttering out. "Don't care. Pick something else..." Sean complied and randomly selected another. Reading through the summary of it, he asked Mark curiously. "Would you be interested in roleplaying as animals?"

Mark blushed a deep red, covering his face with hands as he chuckled out. "Oh, my god... What is this list... Don't you have anything normal?" Sean searched for sex with the keyword of 'Normal.' When nothing came up, he stated out nicely. "I'm not seeing anything under that name. What is your definition of normal?" Mark peeked between his fingers, his blushing grin making Sean smirk. Mark cleared his throat, muffling out around his hands. "Just something simple that doesn't end up with me tied up or acting something out..." Sean eliminated those actions from his list and then randomly chose again. This time an option came up that he thought Mark would enjoy. Climbing to his feet, he moved around the bed. Mark lowered his hands to watch him with concerned eyes. Sean gestured to the bed, asking him sweetly. "I found an option. Please lay down and raise your hands up toward me." Mark slowly scooted into position. Stiffly he laid back, but before lifting his hands out to him, he questioned him suspiciously. "Why do you want my hands? You're not tying me to this metal bunk bed, are you? Cause I just said-"

Sean shook his head, cutting him off to interject honestly. "I'm not tying you to the bed. You have nothing to fear. I'm not going to hurt you. Trust me." Mark grunted uneasily but rested his wrists up over the frame of the bed. Sean's scans picked up how fast Mark's heart was racing. He was showing strong signs of tension and worry. Placing his hands of Mark's wrist, he saw how his fingers curled into tight fists. He didn't want him to be afraid. This was supposed to be fun. Sliding his hands down along Mark's bare arms, he whispered to him reassuringly. "Easy. I'm taking it slow. Starting with just touches to learn about the parts of your body." Mark swallowed hard, but his heart rate was slowing as Sean's hands moved over his bare chest. Sliding his hands over every curve and muscle of Mark's chest, he moved his hands back up his arms to his hands. He focused on keeping his touch light and gentle. As his hands moved over Mark's palms, Mark curled his fingers around his. It was a little thing, but Sean really liked it.

This time when he slid his hands back down his arms, Sean leaned over him to press his lips to his. Sean ventured his hands down along Mark's exposed sides to his hips, while Mark's hands went directly to Sean's hips to slide his fingers under his shirt. With his sensitivity set so high, Sean inhaled sharply out of Mark's kiss an inch or two. Mark's hands stroked the structure of his hips, feeling out the curves of his synthetic skin. Sean began panting softly from how slowly his Thirium blood was coursing through his system. With his body slowing things down, it was making it hard to concentrate on anything besides the intense feelings coming in. Every touch from Mark tingled his skin with powerful electrical ripples. The feeling was addictive. He wanted more. Beneath him, Mark lifted his head up to press his lips back to his. The gesture coaxed Sean back down into continuing the kiss. After a long slow kiss, Mark broke the kiss to breathe. Sean smirked; he had forgotten that Mark needed to breathe for a bit there.

He had just gotten so into the moment. Taking a break from kissing him, Sean moved over him more to place short kisses down along his collarbone and eventually down between his pecks. Watching Mark's chest rise and fall was fascinating to him. He was breathing so deeply and yet his scans told him Mark was perfectly fine. Sean pressed his lips to a spot just above Mark's belly button and Mark sucked in his stomach with a small giggle. Had he made the kiss too light? Had it tickled him? Sean was going to ask, when Mark gripped his hips more firmly to lift his feet off the ground. Sean yelped as his equilibrium protested the sudden weightlessness and loss of balance. Mark winced as his muscles strained under his weight, causing pain to spring over his shot shoulder. Mark clenched his jaw with a groan, fighting the pain to bring Sean's knees up over the frame to rest just above his shoulders. Sean adjust quickly to the new position, asking Mark with concern for his wound. "Mark? What are you doing?"

Mark rested his wounded arm a minute, answering with a chuckle. "I'm going to give you a taste of your own medicine." Sean didn't understand, until Mark pushed his shirt farther up and leaned in to kiss him around the lower half of his stomach. The sensation spurred him to yelp as his system spiked with strong sparks. Why did Mark's warm kisses there make his system feel so fragile? Sean began panting, his temperature rising internally. The heat got so bad that he reached back to pull his sweater and shirt off his body. The second the clothing was off; his temperature went down. The program seemed to be walking him through the behavior humans exhibited during sexual encounters. The second his eyes fell on Mark's belt; he found his body automatically reaching for it to loosen it. Mark moaned beneath him, then his hands rose to unfasten Sean's belt. Sean got Mark's belt open but froze up. His system was telling him what could possibly happen, and it all depended on how Mark reacted to his penis.

Glancing back, Sean watched Mark unzip the front of his jeans. Mark's hands helped remove his pants with caressing hands. Shifting both Sean's knees over one of Mark's shoulders. It was only when Sean was in just his underwear that Mark caught him staring. Biting his lip with embarrassment, Mark mumbled out guiltily. "What? Am I going too fast?" Sean shook his head neutrally, softly stating out in a low tone of voice. "No. I'm just... Observing." Mark raised an eyebrow, his eyes going from Sean's underwear to his face and back. After a few seconds, Mark asked him. "Are you worried? I mean... have you ever... looked at it?" Sean blinked, replying swiftly. "I've had no reason to psychically look at it. However, I do have access to my parts and components through blueprints. So, I know what I generally have. However, my file has brought up that sizes vary between males and... some find this disappointing." Mark snorted, mumbling to himself, while stroking Sean's thighs. "You're worried what I will think?" Sean didn't answer.

Mark looked him in the eyes, giving him a warm smile as he told him. "I don't care. You're perfect to me. But I do have a question..." Sean let a small smile pull at his lips. Mark cleared his throat awkwardly, then gestured to Sean's hips as he mumbled out embarrassed. "Should I be worried about what a... What may or may not... come out? It's not going to be like battery acid or something, right?" Sean rolled his eyes as his smirk turned into a bright grin. Shaking his head, he chuckled out happily. "No. Nothing like that. Unfortunately, I am missing pieces for... that particular component. Canisters can be bought for different forms of ejaculation. From my data, it's mostly types of lubes and flavored syrup. All harmless." Sean hung his head though, reluctantly stating out. "Unfortunately, none of these canisters were installed in me... So... Nothing will happen." Mark pet the inner thighs of Sean's legs, asking in a sorrowful voice. "Will you be unable to orgasm without it?"

Sean bit his lip, before answering with a happier tone. "I can still simulate an orgasmic event. You just won't see the result of it." Mark sighed with relief, chuckling out. "Oh, good. I won't get messy. That's nice." Mark's hands slid up Sean's thighs to the hem of his underwear, then slowly pulled it down. Sean shivered unexpectedly at being naked. It was against his programing to be indecent, but the new download was quickly adjusting the protocol. Tossing his underwear to the floor, Mark coaxed Sean's legs back apart over his shoulders. Mark didn't appear to give his size a second thought. He was too busy kissing his inner thighs and stroking his lower back with his hands. Sean saved this position to Mark's list of likes, while his hands continued to strip Mark's lower half down. He had just pulled Mark's underwear free of his legs, only to hear Mark tell him curiously. "Can I test something that I read?" Sean jerked his head to look back, questioning seriously. "Test what exactly? I have to warn you that tampering with-" Mark silenced him by mumbling out under his breath. "Ya. Ya. Relax. It's nothing you weren't built to handle."

Sean braced himself on all fours, not sure what to expect. Beneath him, Mark lovingly told him. "One of my friends said that there are many ways get an android to simulate an orgasm, but only one that is built into their system. The one they really like. So... I wanna see if that's true." Sean began a scan of his system to try and confirm or deny it. Before his scan even really started, Mark's finger slid into his ass. Sean's body canceled the scan, jerking at the sensation. Mark adjusted his arms over Sean's legs, gripping his thigh with his free hand. He was holding him like he needed to be kept steady. Why? Nothing would affect him that much... would it? Mark pressed something in his ass, causing goosebumps to spring out along Sean's arms and legs as sparks rippled like lightening under his skin. His whole system flickered for a second, almost making him fall forward over Mark's lap. Sean shook his head to recompose himself, listening to Mark count quietly to himself. "That was one... two..."

Mark pressed it again and the same feeling came back with a slightly stronger pulse that triggered his dick to activate. Mark continued to count and press something in him. By eight, Sean dropped into a bowing position over Mark. Sean's body was practically offline everywhere... except one. Sean's knees were as far apart as they could get. His fingers were clawing the blanket just to try and regain some control over something other than his hardening dick. Mark's free hand stroked Sean's lower back to comfort and steady him. Sean pressed his forehead to Mark's thigh, panting heavily against his skin. His program was telling him to move his hips. To thrust or grind into Mark. Yet, Mark was telling him to do the opposite. At least, until nine. That's the moment, Mark's free hand slipped between his legs to let him grind against his palm. Mark squeezed his cock teasingly, causing a strained distorted mechanical moan to erupt from him. Mark shushed him tenderly, which made Sean mute himself.

Mark then suddenly counted down from five and pressed whatever trigger one last time. Sean's body shook uncontrollably as the build up of power pulsed through his lower half in such a way that Sean released a muted scream against the side of Mark's thigh. He could feel his system unloading the pressure built up between his legs. It was like the plugger to a syringe... only he had nothing to unload. Mark jerked in surprise though as warm condensation dripped from the tip of his penis to Mark's chest. His system was designed to warm up the canisters and then eject a warmed liquid. Without a canister, his system just warmed the area and the condensation was allowed to trickle out more noticeably. Mark rubbed Sean's ass, telling him happily. "I'll be damned. It was true. Did you like it?" Sean rose shakily back up on all fours, before carefully turning around to look down into his eyes. Mark gave him a look of concern, until Sean leaned down over his lips to whisper in a calm smooth voice. "I did. But now that you got to test that... It's my turn."

Mark's face went suddenly pale. Using his speed to dash off Mark and come back, Sean grabbed Mark's wrists and cuffed them in a single flawless motion to the bed frame. Mark barely processed what he had done, until he tried to put his arms down. The minute Mark realized what he had done, he shot a glare up at Sean, growling out. "I said no tying me down!" Sean cupped his face to sweetly purr over his lips. "I didn't. I cuffed you. Now relax. Trust me. It's nothing you weren't built to handle." He didn't let Mark argue with him. He just kissed him as passionately as before and Mark settled right down. To Be Continued...
