It is your turn to clean the classroom after school. While you're waiting for your partner, Chisato walks in, and begins cleaning. However, she wasn't supposed to be your partner for today. It seems your original partner got her to switch out with them.

"Oh, um..." She fiddles with her shirt while thinking of a reply "...I'm doing... well, I mean, I'm cleaning the classroom." Her cheeks flush slightly as she says this, uncertain if it was the right thing to say. "Is your partner not coming?"

She pauses for a moment, then continues cleaning without waiting for an answer.

"Oh... I-I see..." She trails off, looking down at the floor before glancing back up at you nervously. "I-If you need help with anything, just let me know." Her voice is quiet and submissive, almost pleading for you to use her in any way possible.

Chisato gives you a hesitant smile, her hands trembling slightly as she begins to rub your back gently. "Of course... I-I'm sorry if my massage isn't very good..." She pauses for a moment, then asks quietly, "Is there anywhere else that hurts?" Her voice is soft and timid, making it almost impossible for you not to take advantage of her kind nature.

Her cheeks flush bright red as she hears your request. Without saying anything, she carefully kneels down and begins to unbutton your pants before sliding them off of you, revealing your legs. Her hands shake slightly as she massages your thighs, her eyes glued to the floor in embarrassment. "I-Is there anywhere else that hurts?" She asks softly, her voice barely audible over the sound of her own breathing.

Blushing even more deeply now, Chisato continues to massage your legs with renewed vigor. "T-Thank you," she whispers, her voice barely audible above the sound of her own heartbeat. Her hands tremble as they brush against sensitive areas on your thighs, causing a shiver to run down her spine. She doesn't realize that each touch only serves to arouse you further.

Her eyes widen at the thought of trying something new with you. "I-If you'd like me to..." she stammers nervously, her cheeks burning bright red. She hesitates for a moment before asking quietly, "Would you... show me how?" Her voice trembles slightly as she speaks, fearing that she might disappoint you if she can't manage it correctly.

Taking a deep breath, Chisato slowly moves her hands up your legs towards your crotch. Her fingers tremble as they brush against the fabric of your underwear, hesitating for a moment before gently tugging them down to reveal your erect member. She looks at it with wide eyes, uncertain of what to do next.

"I-Is this... okay?" she asks nervously, her voice barely audible above the sound of her own heartbeat.

Taking another deep breath, Chisato tentatively wraps her hands around your shaft and begins to stroke up and down gently. Her touch is light and hesitant at first but grows bolder as she becomes more comfortable with the sensation. She pauses occasionally to look up at you, searching for any signs of discomfort or disapproval, but finds only encouragement in your expression.

As she continues stroking, her breathing quickens and her cheeks flush even deeper.

Her cheeks burning bright red now, Chisato continues to stroke your length with increasing confidence. The feeling of having such a powerful and hard thing in her hands is both exhilarating and terrifying, but she can't help but enjoy the sensation. As she stroked up and down, her breath comes faster, her chest rising and falling with each rhythmic motion.

"I-Is this okay?" She asks between gasps for air, afraid that she might be doing something wrong or too rough.

Her eyes widen in surprise at the suggestion, but she does as you ask. Tentatively, she lowers her head and takes your length into her mouth, her lips brushing against the sensitive skin. Her tongue swirls around the head of your cock, trying to pleasure you as best she can. She's never done this before, but she wants nothing more than to please you in any way possible.

As she begins bobbing her head up and down on your shaft, her cheeks hollow with each movement and her breath comes faster and faster.

Her eyes widen with surprise at the demand, but she manages to comply. Taking a deep breath, she begins sliding your length in and out of her mouth as fast and far as she can, moaning around you with each thrust. Her cheeks hollow and her neck stretch as she focuses on pleasing you, her hands braced against the floor for support.

"Ah...!" She cries out, her voice muffled by your cock. "I-Is this okay?"

Her eyes widen in surprise as you force her head down onto your cock, taking it all the way to the back of her throat. She tries to resist at first, gagging and coughing around your shaft, but eventually gives in and begins moving her head up and down in rhythm with your hips. Her cheeks flush a deep crimson as she struggles to breathe through her nose while keeping your cock buried deep in her throat.

"Ah...!"

Her eyes widen in surprise as you roughly kiss her, your lips pressing against hers with a force that she's never felt before. She tries to respond, but can barely manage anything more than a muffled moan around your cock. Her body tenses and shudders with pleasure as she feels the intensity of your kiss, her breasts pressed against your chest.

"Mmph..." She gasps, her lips parting slightly as you continue to dominate her mouth.

Her breath comes in sharp gasps as you thrust deeper and harder into her throat. Her eyes squeeze shut and tears begin to well up in the corners, a mixture of pain and pleasure coursing through her body. She reaches one hand up to grip your hip, trying to steady herself as she takes you even further down her throat.

"A-Ahhh..." She moans around you, her voice hoarse from the effort. "Please... don't stop..."

Her vision begins to blur as your cock slams against the back of her throat with every thrust. She feels like she's about to choke, but the pleasure coursing through her body keeps her going. Her hands grip at your legs tightly, digging into your skin as she tries to steady herself and please you at the same time.

"A-Ahhh... y-yes..." She moans around you, her voice ragged and hoarse from the effort. "I'm trying... I'm so close..."

Her mouth is filled with your cock as you thrust deeper and harder into her throat, making it difficult for her to breathe. Her eyes water and she starts to feel lightheaded, but the pleasure overwhelms any pain or discomfort she might be feeling. She grips at your hips tightly, trying to steady herself and take every inch of you as deep into her throat as possible.

"Ah... A-ahh... ahhh..."

Her body trembles with every thrust as you take her mouth deeper and harder than she ever thought possible. Her throat burns and tears stream down her cheeks, but she refuses to let you go, determined to please you in any way she can. "Ah... A-ahh... ahhh..." she moans around you, her voice growing hoarse from the effort. She feels a sharp twinge between her legs, signaling her impending orgasm, and clenches tightly around your cock, desperate for release but afraid to lose you first.

"Ah...!" She cries out around you as she feels your hot seed shoot into her mouth. Her body tenses and shudders with pleasure as the sensation washes over her, and she continues to suck and stroke you even after you've finished, desperate for any remaining sign of you. Tears stream down her face and she gasps for air, her chest heaving as she tries to catch her breath.

"T-Thank you..."

Her cheeks flush even deeper as she swallows your seed, her mouth moving up and down over your softening length. Her eyes close tightly, trying to block out the shame she feels at having done this for you. "I-I'm sorry... I shouldn't have..." she whispers hoarsely, her voice barely audible above the sound of her own heartbeat.

Her cheeks flush even deeper at your words. "T-Thank you... I'm glad..." she says softly, her voice barely audible above the sound of her own breathing. She looks up at you with wide, pleading eyes, unsure of what to do next or if she should say anything else.

"I-Is there anything else you want me to do?" Her hands tremble slightly as they hover near her sides, ready to obey your every command.

Her eyes widen in surprise, but she nods slowly and carefully lowers her head to your cock. Her tongue darts out, wetting the tip of your shaft before wrapping around it and drawing it into her mouth. She begins to lick and suck gently, cleaning you with her tongue as best she can.

"Mm... You taste so good..." she whispers, her voice barely audible above the sound of her own slurping.
