"Are you sure you want to try this?" You asked Aki, running your hands down his bare thighs as you sat on his lap. "Just because it's a fantasy of mine doesn't mean we have to do it."
Aki looked up at you, eyes gazing into yours as he took a deep breath. "I want to," he said. "You know I'd do anything you could ever want to do."
You let out a soft laugh, running your hands down his thighs again as you could feel his tighten their grip on your thighs. "Alright," you murmured, leaning down to kiss his forehead chaste. "Go take a shower and get ready; I'll get everything set up."
Aki nodded, helping you get off his lap as he slid off the bed, pressing a quick kiss to your lips before he disappeared into the bathroom, the door shutting behind him.
You moved to your closet, humming to yourself as you heard the shower begin to run as you grabbed your box of toys, pulling out exactly what you'd need for this experience.
Moving back to the bed with everything in hand, you quickly spread it across the plush duvet. Lube, the harness, the dildo, and towels for easy cleanup all sat lined up in the order you'd need them for easy access.
You double-checked that you had everything before slipping your clothes off, leaving you bare save for your underwear so that nothing would get in the way of the activities about to ensue.
The door to the bathroom opened a few minutes later; Aki stepping out of the room with a towel slung lowly around his waist, hair down with water droplets still dripping down his chest.
You bit your lip as you looked him up and down, motioning him over. "Come here, handsome," you cooed, letting out a soft laugh when you could see his cheeks flush red. "I'm all ready for you."
Aki nodded, walking over to the bed and sitting beside you, grabbing your hand and squeezing it softly. "You'll go slow, right?" He said quietly, looking over at you.
You nodded, pushing him gently so that he was lying on his back as you straddled him again, leaning down so that your face was only a few inches apart. "Of course, I'll go slow, don't worry."
He nodded again, leaning up on his elbows so he could connect his lips with yours, pressing softly together before your tongue slid into his mouth, brushing against his as you began to slowly grind your hips against his, smirking into the kiss as you could feel his growing bulge beneath your ass.
You pulled away from the kiss a few moments later, pressing your lips against his neck as you sucked a hickey into the skin, soothing the blooming mark with your tongue before continuing down.
Aki watched your movements with lidded eyes, breathing heavily as you moved to situate yourself lower, removing the towel off his lower half so that he was completely bare in front of you. You were using your hands to push his knees apart gently, spreading his legs so that you could situate yourself between them.
"You ready?" You murmured, kissing the insides of his thighs as you reached for the lube, popping the cap open.
"Yeah, I am," he nodded, spreading his legs wider as he watched you drizzle the lube onto your fingers, spreading the slick liquid around to warm it up slightly.
"Alright," you nodded, using your clean hand to spread his asscheeks and circling the tip of your pointer finger around his hole. "Just relax for me, yeah? It'll be easier that way."
You could feel Aki relax as you circled his hole before gently sliding your finger into the first knuckle, looking up at him to gauge his reaction. Aki whined at the intrusion, clenching as he felt you slowly move your finger in, finally fully in.
"I'm gonna begin moving it now, okay?" You asked, pausing for a moment before slowly sliding your finger in and out.
Aki let out a shuddering breath, throwing his head back as he got used to the foreign feeling. "You can add another," he said after a moment, looking back down at you.
"Alright," you cooed, pulling your finger out before sliding your middle finger alongside it. Aki groaned, clenching down around your fingers again as you slowly pumped in and out, scissoring them apart to aid in stretching him out.
"Oh fuck," he whined, legs shaking slightly as your fingers brushed up against his prostate, bringing a smirk to your face as you curled your fingers to hit it once again.
"Right there?" You let out a soft laugh, continuing to angle your fingers to hit that spot every time you'd slide them back inside, delighting in the soft whines slipping from your boyfriend's mouth.
"God, yes, right there," he groaned, another soft moan slipping from his mouth as you pumped your fingers inside again. Feeling that he was ready, you slid your ring finger in alongside the other two, ripping another loud whine from Aki's mouth.
Your fingers continued sliding in and out, opening him up further before you pulled them out completely, wiping them down on the towel beside you. "You ready for the strap?" You asked, looking at him as you reached over to grab the harness and dildo.
Aki nodded, face already flush just from being fingered open. "I think I'm ready."
"Perfect," you smiled, pressing a kiss to his knee before sliding the harness on, making sure it was on correctly before putting the dildo in place, pouring more lube into your hand as you stroked it.
You leaned back down again, lining the strap up with his hole before slowly pushing inside, gently massaging his thighs as you pressed inwards. Aki groaned again, taking a deep breath as you finally bottomed out, hips flush against his ass.
You stayed completely seated in Aki for a few moments, letting him get used to the feeling of being full, waiting for him to permit you to begin moving.
"You can move now," Aki murmured, looking at you. You nodded, gently gripping his legs to wrap them around your waist as you slowly slid out before thrusting right back in.
A strangled gasp was ripped from his mouth as you began to move, the slick sounds of lube beginning to fill up the room as you continued, angling your hips better so you could piston the strap into his prostate with every thrust.
"Fuck, just like that," Aki whined, legs beginning to shake as his cock bounced back against his stomach, a small pool of precum growing as your thrusts picked up again.
You leaned over him, connecting your lips to his in a sloppy kiss as your hips continued to move, swallowing up his whines as he gripped your shoulders, legs tightening around your waist.
He looked so beautiful like this, underneath you with his face flush, tears pooling in his eyes as he gazes up at you with still-lidded eyes, pupils blown wide with lust.
"Look so nice like this, Aki," you murmured, moving to mouth at his neck again. "Doing so good for me, yeah? You like being my good boy?"
Aki moaned again, preening at the praise as his back arched up, cock twitching once more as another bead of precum dribbled out of the tip. "Yeah, I like being your good boy," he mumbled, glassy eyes meeting yours.
"I knew you would," you cooed, licking a stripe up from the base of his neck to his jaw, nipping at the skin afterward.
His legs began to shake even more as he grew closer to his climax, which you took note of as you took his cock in your hand, stroking in time with your thrusts to help bring him over the edge.
Aki came with a broken moan, eyes rolling back as he leaked all down your hand, cock still twitching as you helped him ride out his orgasm.
You pressed a few soft kisses to his face before you slowly slid out of him, Aki hissing at the feeling of being empty as you grabbed the towel again, wiping your hand down before cleaning up the leftover mess on his stomach and moving to clean up some of the lube from between his cheeks.
He had his arm tossed over his head, breathing heavily as he still came down from his high. "I didn't expect to like that as much as I did," he murmured, pulling his arm from his face as he looked at you.
You giggled, laying down next to him and kissing his cheek again. "You took it like a champ," you murmured. "Did so good for me."
Aki huffed, rolling his eyes despite having a soft smile on his face. "I'm assuming you enjoyed it as well?" He asked, turning his head to look over at you.
"I did," you grinned, resting your head on his chest. "I would like to do that more often if you're fine with it."
Aki laughed again, moving his hand through your hair as the two of you relaxed on the bed. "We can do it anytime; I don't mind."
"Good to know," you grinned again before sitting back up and looking at him. "Now let's go get you cleaned up."
