You pulled up your swim trunks, the waistband snapping into place. It felt odd to be putting on a swimsuit when you weren't going to the beach or pool today.
Hitotose Manor was unusually quiet, most of its residents away for the day. The only ones left were you and the landlady Hagino Chiaki. Chiaki was planning on cleaning up the bathroom today and you had volunteered to help her out. This was why you were wearing a swimsuit. Chiaki suggested to dress this way to avoid getting your clothes all wet. You didn't argue with her. No way you would turn down a chance to see Chiaki in a swimsuit!
Exiting your room, you strolled down the empty hallway, the sound of your bare feet pattering against the floorboards echoing off the walls. Reaching the bathroom, you found its door partially ajar. You could make out the sound of Chiaki humming to herself as she scrubbed away at something. Taking a deep breath, you gently pushed open the door. Your eyes were greeted to the sight of the swimsuit clad Chiaki on all fours in the bathtub, facing away from you as she scrubbed away at some grime.
Chiaki was dressed in a simple white bikini that clung to her body ever so nicely. The bottoms were struggling to contain her plump cheeks, the top of her ass crack visible to you. Her top was also fighting to contain its respective set of assets, her large breasts hanging freely, lightly swaying with each scrub Chiaki performed, the strings of her swimsuit pulling taut. You soaked in the exposed undersides of her mammaries, feeling your own swimsuit becoming tighter at the front. You quickly moved to tuck your swelling cock underneath your waistband, your hands completing their task right before Chiaki noticed your presence.
"Ah? You're here."
Chiaki rose to her feet, water and soap bubbles dripping down her body. Your eyes were glued to her long slender legs as she swung them over the side of the tub to get out.
"S-Sorry for the wait senpai!" you replied, your voice cracking from nerves.
"Don't be. I appreciate you taking the time to help me."
"It's no biggie! I didn't have any plans today anyway! Heh heh…"
Your heart was pounding. Being alone with Chiaki in a swimsuit was doing a real number on you. You could even feel your heartbeat in your dick, pulsing beneath your waistband.
"I've already made a start on the bathtub. Do you think you can handle the sink and cabinet?"
Chiaki gestured to the sink, where you noticed that a bucket of soapy water and a sponge were resting beneath it.
"Sure! Leave it to me!"
The two of you got to work, Chiaki climbing back into the tub, you taking the chance to eye up her ass as she did so before making a start on your own task. You started with the sink, scrubbing its basin sparkling clean before moving onto the cabinet, carefully emptying it of its contents first, bottles full of who knows what.
While this work was relatively time consuming as is, the length of your task was lengthened by you constantly stealing glances over at Chiaki. Her body was covered in soap and sweat. Each little movement she made caused her assets to jiggle and sway. At one point you watched her wring out her sponge, soapy water dripping down onto her chest, leaking into her cleavage. You struggled to tear your eyes away.
Time passed and soon both of you had completed cleaning your respective parts of the bathroom, the room now sparkling like new.
"We did it!" Chiaki cheered softly, performing a little hop that caused her chest to steal your gaze once more.
"Thank you again for your assistance today."
"Don't mention it! I'm happy to have been of help to you senpai!"
As you began to tidy up the cleaning supplies, Chiaki spoke up.
"We're not done yet."
"Hmm? We're not?"
"Nope. There's still one more thing left to clean."
Chiaki approached you before dropping down to her knees.
"There is? What's tha-"
You were cut off by the gentle feel of Chiaki's hand planting itself upon your crotch. You froze, feeling her fingers lightly grip your swollen shaft.
"This. It's been hard the entire time, hasn't it?"
"I… I can explain!"
Chiaki giggled softly at the panic on your face.
"No need. I understand how men are. You can't help it."
She gave your cock a small squeeze, a moan slipping past your lips, much to your embarrassment.
"It must be hard, being the only boy in a house full of girls. You probably don't get many chances to take care of certain needs."
Chiaki assumed correctly. Living under the same roof with four girls left you precious little opportunities for privacy. It didn't help that all of them were attractive, their mere presence enough to get your blood pumping. You rarely got the chance to drain your sack, leaving you plagued with regular wet dreams. Just a few days ago, Kuu and Mayu had questioned you on why you were constantly washing your sheets.
"You're always going out of your way to help me and the other girls." Chiaki continued, her hand continuing to lightly stroke your shaft through your trunks which had become awfully tight thanks to all the water, leaving the shape of your cock quite visible to Chiaki.
"As thanks for that, and as an apology for the stress our presence likely causes you, allow me to take care of this for you."
Was this for real? Was Chikai seriously offering to tend to your hardon? You didn't dare question her or ask her if she was sure. You just nodded, accepting her offer before she had the chance to take it back.
Gripping the waistband of your trunks, Chiaki began to tug them down your legs. Your cock was briefly pulled down with them before springing free, standing tall and proud, looking more engorged than you had ever seen it before. Chiaki let out a small coo of awe, her eyes trailing up and down the underside of your length as she took it all in.
"Oh my! You're quite big!"
"Thanks…" you replied softly, avoiding eye contact as you felt your cheeks heat up.
Chiaki returned her hand to your now uncovered dick. You pursed your lips tight to hold in a gasp, Chiaki's soft touch like fireworks to your nerves. You leaned back against the sink, hands gripping the edge of the basin as Chiaki got to work. Her hand began to glide up and down your length, each rubbing of your tip causing a moan to escape your lungs. Chiaki's hands were still soapy, so a lather soon began to form along your shaft, allowing Chiaki to both pleasure and cleanse your dick. You couldn't get over how good this all felt. Had Chiaki done this before? She certainly seemed to know what she was doing!
"How does it feel?" she asked, her hands taking no pause from her work as she looked up at you.
"Amazing…" you responded, only able to give a single word answer.
"Mmm… My breasts aren't distracting you, are they? You've been staring at them this whole time."
"N-No! I was just…"
Chiaki giggled at your flustered response.
"I'm just teasing. You can touch them if you want."
You gulped. Chiaki had just given you permission to touch her tits. The same tits you've been secretly pining for ever since you moved into Hitotose Manor.
Your right hand left the sink, trembling through the air as it hovered towards Chiaki. It gently cupped her left breast, your hand carefully slipping underneath the flimsy fabric of her bikini top to grope her breast directly. It was truly the most heavenly thing you had ever touched. Its volume, its weight, its shape, its size, its feel. Everything about this tit was perfection incarnate. You were so enamoured by Chiaki's boob that you momentarily forgot that it had a sister, just waiting to be squeezed. Your left hand quickly left the sink to join his brother at Chiaki's chest, taking hold of her right breast before sinking its fingers into the large orb's yielding flesh.
As you fondled Chiaki's breasts, her hands continued to tend to your manhood. Her left hand was like a blur at this point, racing along your bubble covered length, each touch like lightning. Meanwhile, her right hand had drifted down to your balls. It carefully scooped up your swollen jewels, feeling the weight of your pent-up seed. Chiaki gently began to massage your tender nuts, coating them in a similar bubbly lather as the one that adorned your cock.
You let out another moan, one that sounded a bit pained as you gave Chiaki's tits a hard squeeze. You were so close… oh so close! Just a bit more and you'd…
Suddenly, Chiaki pulled away from your soapy junk. You released your hold on her breasts, gazing down at Chiaki with confusion. Had you done something wrong? Chiaki failed to stifle her laughter at the utter distraught written on your face.
"I'm sorry. I just thought that since you like my breasts so much that perhaps you might like to finish in them instead?"
Finish in between her breasts?! You nodded rapidly, hard enough that your head looked like it might snap clean off your shoulders.
Chiaki reached around to her back, undoing the knot to fully remove her bikini top, tossing the flimsy garment to one side. Chiaki then cupped her heavy melons and began guiding them towards your throbbing length. Spreading them apart, she maneuvered her boobs to opposing sides of your cock before pressing them together, trapping your dick between them.
Your hands rushed back to the sink, gripping the basin hard for support as you briefly rose to the tips of your toes before settling back down on your soles. Chiaki resumed the treatment she had been giving your dick, only this time with her breasts rather than her hands. She gelled her breasts around your cock, twisting and shifting your trembling rod about in its prison. You were moaning like crazy now, your entire body shuddering. You were in heaven. You wanted this to last forever. But after having already been brought to the edge by her hands, you knew that you didn't have it in you to endure Chiaki's tits for long.
With your hands boring down on the sink to the point that you feared you might break it, hot cum began to rush up your cock, erupting between Chiaki's tits. Chiaki let out a startled yelp as a particularly powerful spurt burst from her cleavage, pelting the left side of her face. For her part, Chiaki didn't let up on the treatment she was giving your cock. She wanted to ensure you got a proper milking and boy did she succeed! You don't think you have ever cum as hard in your life! You were barely able to remain standing by the time your ejaculation had finally reached its end.
Chiaki was left in complete awe as she stared down at the absolute deluge of semen you had deposited between her breasts, some of it leaking out from the bottom of her cleavage, dripping down onto her thighs below.
"Amazing… I didn't know guys could cum so much!"
Rising up from the floor, Chiaki moved to the tub. Bending over the side with her back to you, Chiaki reached for the showerhead. Turning it on, she began to carefully rinse off her chest, your semen slowly washing down the drain.
As you caught your breath, your eyes hovered towards Chiaki's backside. Chiaki was humming as she washed herself, her rear end rhythmically swaying from side to side as she did so. You found yourself falling under a hypnotic spell, blood rushing down southward as your dick swelled back to its full might. Unable to resist, you approached Chiaki and grabbed onto her hips.
"Eh?" she gasped from the sudden content, looking back at you with startled confusion.
"Sorry senpai… But I… I can't…"
You pushed aside her bikini bottoms with your dick, allowing you to slide your phallus between her ass cheeks. You began to saw your length between those soft mountains of flesh as Chiaki watched on with an amused look.
"You're that pent up, huh?" she asked, which you could only respond to with a nod.
"I see… in that case…"
Chiaki reached back for one of the knots of her bottoms, untying it. The garment slid off her body, briefly draping over your shaft before slipping off onto the floor. You gulped as you took in the now completely naked Chiaki, both her bare ass AND her pussy on display!
Chiaki's hands reached around her rear, fingertips carefully hooking onto the lips of her pussy. She spread her folds apart, exposing the insides of her sex to you.
"You can use this to relieve yourself."
You gulped again at the sound of her offer.
"Senpai… are… are you sure?"
"Mmm. It's safe today so go ahead. Use me until you're satisfied!"
You didn't need to be told twice. You wasted no time lining yourself up with her entrance before pushing your dick inside Chiaki's pussy. You felt your dick push through something, causing Chiaki to tremble. A quick glance down at the blood that now adorned your length told you what it was.
(I just took Chiaki's virginity?!)
That knowledge emboldened you, fuelling your thrusts as you rutted into Chiaki like an animal in heat. Her velvetlike walls massaged your length, assisting you in reaching deeper into her cavity as your inches all gradually disappeared inside Chiaki until you were able to sink right down to the hilt. She let out a gasp as you bumped against her cervix, sending a tremor into her sensitive womb.
"Senpai…" you gasped as you continued pounding into her.
"Call me by my name." she asked breathily.
"Chiaki…" you replied, punctuating it with an extra hard plap before repeating her name several more times.
Sounds of copulation echoed off the tiled walls of the bathroom as you carved your dick's shape into Chiaki's yielding pussy. You soon reached down over her body, resting your own atop her sexy back as your arms snaked down to latch onto her hanging breasts, their constant swinging in response to your thrusts too alluring to ignore.
Despite this scenario being meant for your benefit, Chiaki could not deny the pleasure that she herself was feeling as soft, sensual moans soon began to leak from her lips. She shouldered a lot of responsibility both at home and at school, so she was well in need of some stress relief, relief she was now getting as her hips began to rock back to meet your thrusts.
Your balls felt like they were on the verge of bursting. Millions of your potent swimmers were ready to storm Chiaki's womb. While it may have been a safe day, the fantasy of knocking up Chiaki dominated your mind. Pushed forward by that tantalising dream, you sheathed your entire length inside Chiaki with one final, powerful thrust, her buttocks flattening against your pelvis as you pushed as deep into Chiaki as you could. You groaned as you felt your thick hot load force its way along your shaft, your entire world going white the moment that first salvo of spunk was jettisoned from your tip.
Chiaki experienced an orgasm of her own as she felt her womb being pumped full of your molten warmth, her deepest parts becoming stained in your essence. Her body shuddered beneath your own, her vaginal walls becoming vicelike as they tried to harvest as much of your lifegiving seed as possible.
With your balls thoroughly drained and Chiaki's womb filled to the brim, you withdrew your wilting phallus from her reddened sex. You fell back onto the floor, your ass growing a little sore from the impact against cold hard tile. Chiaki remained bent over the side of the bathtub, her upper half collapsed into the tub, allowing your eyes to linger on both her ass, as well as her pussy, watching as some of your cum leaked out of her. She eventually summoned the strength to lift herself out of the tub to face you, her warm smile making you feel lightheaded.
"Mmm… I hope you enjoyed that as much as I did♪" she asked, giving her belly a playful rub.
"Y-Yeah… Thank you sen-, Chiaki…"
You were still feeling too weak to get up but Chiaki didn't appear to have that issue as she rose to her feet. She moved towards you, planting her hands on her thighs as she bent forward, your gaze stolen by her hanging breasts before you managed to force your eyes to meet hers.
"This should go without saying but please keep today a secret from the others."
"O-Of course! I promise!"
Chiaki smiled at you before moving to pick up the pieces of her swimsuit, your eyes on her perfect body the entire time. Your gaze remained on her as she headed for the door. She stopped in the doorway, you once again having to force your eyes to meet hers as they lingered on her rear.
"Oh, and… if you ever get pent up like that again. Just let me know, okay?"
"C-Chiaki… I… Is that really…"
"It is. After all… boys aren't the only ones with needs you know♥"
And with that tantalising claim, Chiaki took her leave, closing the door behind her. The moment you were left alone with your thoughts, all your strength finally left you, causing you to collapse onto your back where you remained for some time. Poor Hinako was left with quite a shock when she came in later to use the bathroom, only to find you passed out and naked on the floor.
