"Is that a challenge?" Otto grumbled, barely lifting his eyes from his drink. As you two sat on the couch, his mechanical arms began to whir. Leaning over to him, you chuckled. "I'm just offering, dear; you always treat me so well, don't you want to let go a little bit, doctor?" There was a deafening silence as your confidence faded, had you made him angry? Otto sighed, then smiled mischievously at you. "I like things better when I make you squirm, when I hear your lovely moans, when I make you beg for more. Are you saying you'd like to do that to me?" In that moment, you felt two feet tall. You knew then that it would be hard to break the scientist of his 'bad' habits.
Otto's smooth voice cut through your thoughts. "I'll take you up on your offer, (y/n), but I'm a little inexperienced." He pushed you closer to him with one of his aculators. "Would you like to walk me through it?" As he rapidly advanced the situation, you decided to suspend it, so Otto could preserve all of his energy for when you were better prepared. You got off the couch and told him to wait until it was time for bed. Yoy tried your best to look sexy exiting the room, leaving Otto hot and bothered.
Later, at night, you read a book in bed, and as Otto walks into the room, he inquires about your offer. "Oh, Otto, looks like you're chickening out." He moves one of his mechanical hands to grab the blanket from the bed, but just as he's about to get in, you move closer to him, until your chests are inches apart. Otto looked straight at you, eyebrows furrowed, deep in thought, trying to figure out your next move. Quickly, you slam your mouth into the scientists, while reaching behind him and into the nightstand for a new bottle of lube youd placed there earlier. Otto noticed your scheme and gripped your wrist with one of his actuators.
"You sly dog." "Deactivate them." Otto rolled his eyes, laid his extra limbs on the bed, and cautiously shut off his mechanical spine, all while you kept a close eye on him to ensure he followed through. Hungry to continue, you pull Otto back into the kiss. As his tongue slides its way into your mouth, You begin to moan into his. The scientist tries to dominate you and distract you from your mission, but as he grabs your side, you step up and stop his hand. After sliding his hand away you gently push Otto until he falls back into the bed.
"Aren't we gonna get on with this, honey?Or are we going to foreplay all night..." You turn away from the bed to get ready and put a condom on. While you're doing so, Otto unbottons his shirt and lets down his pants. When you turn back around, you see the scientist leaning back on the matress, shirt discarded, pants and underwear wrapped around his ankles. Your heart skips a beat as you open the lube bottle and bend down by the bed, telling Otto to get on his knees. "As you wish."
You lubricate your fingers and slide one into Otto's asshole, slowly flexing it."How's that feeling, Otto? Are you okay?" You ask, and Otto is shockingly quiet. "Ye-Yeah, it just... feels a little strange." He can feel your worried eyes burning into him, so he tries to reassure you. "You don't have to be gentle with me (y/n), you're the expert." After a few minutes of stretching and fingering him, you asked Otto if he's ready for you, which felt embarrassing to say. He raises his head and casts a glance over his shoulder at you. "Well, we've come this far, and you did just fingerblast me for 10 minutes, so..."
You tentatively grip his thick hips, trying not to dig your nails into his skin as you slide a little bit inside of him with a quiet squelch. Otto shudders, but tries to remain calm. "And you told me you were good at this? I didn't even feel you put it in." You knew Otto was lying, but the attempt was to make everything feel less awkward, and you admired that. The attempt didn't work that well, as you eventually freeze in place, an awkwardness filling the air. Otto let out a small chuckle as you sheepishly asked if you could start moving. "You've got me on my hands and knees, honey. Yes, I'm all yours tonight." Confidence washes over you, and it took all of your strength not to cum right then and there.
You gradually began to jerk your hips back and forth, eliciting groans from the man bending over in front of you. When you felt Otto throbbing around you, you grope his hips and started going a little faster to see how he'd react. Otto bit his lips, attempting to mask his moans, but you leant down over his shoulder and kissed his neck, persuading the scientist to stop. "Come on, Otto, you sound like you're having a good time." You try to maintain your composure as your pleasure grows. Otto stops biting his lip, but he turns his head away from you. "I can't hear you, Otto." He still refuses to moan for you, so you decide to provoke them.
Otto felt your hands prying around his body, hazily grabbing at his nipples and fluffing up his hair. You can feel him clenching tightly around you, unaccustomed to being touched. "Relax, Otto, it's ok, I'm taking care of you." You fawned at him, as you ran your hands through his hair. "Nngh," Otto muttered as you slowly pulled his head back. "Was that a moan I heard?" You cooed as you continued to stimulate his now shivering body with your hands. After your left hand had finished playing with Otto's nipples, it slithered down his bear trail and grabbed onto his dick, veins throbbing.
Otto let out a sound that sounded like a cross between a gasp and a moan, and you complimented him on the volume, much to his flustering. You thrusted into the scientist at a constant pace, your undivided attention focused on stroking Otto's cock. You rubbed your thumb across his urethra, which seemed to push him over the edge.
Otto moaned in low tones, and you leant over his shoulder, mumbling praise as you pumped him through his orgasm. "There you go, Otto, that's my good boy. I'm proud of you for stepping outside your comfort zone." Otto only breathed heavily, mouth agape. Drool dripped out of his mouth as he came onto your hand and the sheets. Hearing his moans and feeling him contract around you was enough to make you cum soon after, the fluid dripped down your legs.
You look up at the clock and notice that it'd been 22 minutes since you and Otto's 'adventure' began, and you wondered how Otto had managed to stay up on his knees for so long. As if on cue, Otto drops to the bed on his belly, and you fell down with him, your stomach brushed against his mechanical spine. You pull yourself and the condom out of him, rolling off of his back and onto yours, Otto's arms moved out of the way to accommodate. You jump up and slowly turn your head to face your partner. The scientist, red faced, hair a mess, stares at you blankly.
"Y-you probably... turned them on while laying behind me." You gave him a skeptical look, and he sat up, raising his hand to your face. "Trust me, (y/n). I never doubted you for second." Otto rubs your face. "I felt good, I hope you did too. maybe we can clean up later, you did... an excellent job." Otto, awkward like you'd never seen him before, wasn't used to talk after having sex in a way like this due to it being his first time, so he gave up on the half-baked compliment and settled for kissing your cheeks and bear hugging you until you both fell into the bed. Even though you were both sweaty and hot, you found joy and comfort in tangling around each other. Smiling as wide as ever, you looked up at Otto. "See baby, all you had to do was let go."
