I reached for the nightstand again and pulled out a slim anal vibrator, black and sleek, its tip rounded. I let it hum to life in my hand. The low buzz filled the room.
Kotoha's eyes widened, her body tensing against the restraints. "…T-that's… going inside me…?"
"Of course. Don't you want to feel good?"
Her voice shook. "Ahh… Souta-kun… it's scary…"
I pressed the tip against her slickened rim.
"Relax. You're already stretched. Just breathe."
She whimpered as the toy slid past the tight ring, her ass clenching around it. Inch by inch, I worked it deeper until only the base remained outside. I switched the vibration higher.
"Ahhh—! Ahhhhnn! It's buzzing inside me—!"
Her body jolted, her thighs trembling violently. Her hips squirmed against the sheets, juices dripping fresh from her pussy.
"That's right," I said, twisting the toy slowly. "Now every time your ass clenches, you'll feel it vibrate harder."
Her moans filled the room. Sweet and pleasant.
"Nnghh… I can't… I can't stop shaking… my pussy's dripping everywhere… ahhh!"
Her moans drove me harder. I reached up, unbuckled her cuffs, and freed her wrists. Before she could lower her arms, I grabbed her hair and pulled her up to her knees on the bed.
Her face was flushed, sweat sticking her bangs to her forehead. "Souta-kun…?"
I unzipped and pushed her lips open with my cock. "Use your mouth."
"Yesss~♡"
Her eyes widened, but she obeyed instantly, opening wide. I shoved myself in, groaning as her hot throat enveloped me.
Her twin tails swayed with each thrust as I held her head, guiding her down until my tip hit the back of her throat. She gagged softly, tears pricking her eyes, but she kept swallowing around me.
"Nghh—good girl."
Her muffled cries vibrated along my length, making me shudder. Drool spilled from her lips, dripping onto her chest, mixing with sweat. Her hands clutched the sheets as her whole body shook, the vibrator still humming in her ass.
I slammed deeper, her throat convulsing as her eyes rolled back. Her pussy gushed again, soaking the bed, as she came from the overwhelming assault.
"Mmmmhhhnnnnn!"
I held her head down until her throat swallowed every twitch of my cock, then let her up for a desperate gasp of air. Strings of spit clung between her lips and my shaft.
"…Souta-kun… I came again… my ass… my throat…"
I tightened my grip in her hair, pulling her head back just enough to make her look at me. Her eyes were glassy, tears clinging to the corners, lips swollen and slick with spit. The faint buzz of the vibrator inside her ass filled the silence.
"Not yet. I'm not done using your throat."
She smiled sweetly and opened her mouth again. I slid myself in deep, groaning as the heat of her throat swallowed me whole. Her gag reflex twitched, her body jerking against me, but she didn't resist. She clung to my thighs instead, her nails digging into me as I began to thrust.
Her gag reflex had gotten a bit better, but it was still there. Still, her effort made me excited beyond belief.
"Good girl. Take it all."
Her twin tails bounced with every push. Drool streamed down her chin, dripping onto her bare chest and nipples, which were still red and stiff from my week of training. Every time my cock hit the back of her throat, she let out a muffled cry, the sound vibrating around me, driving me insane.
I reached down with my free hand and twisted the vibrator's dial higher.
Kotoha trembled around my cock, her whole body jolting as the toy buzzed furiously inside her ass. Her hips bucked, juices squirting messily from her pussy, soaking the sheets beneath us.
"Mmmhhhhh—! Nghhh! Nnnnn!"
Her muffled screams and the clenching of her ass told me she was cumming again.
I gritted my teeth and thrust faster, using her throat like it was mine alone. My balls slapped against her chin, her saliva coating every inch of me. Her eyes rolled back, tears streaming as she convulsed from the double assault.
"Kotoha! I'm cumming!"
Pulling her head down one last time, burying myself to the hilt.
She gagged, throat spasming around me just as my cock twitched. Hot spurts of cum shot down her throat, filling her until she choked on it.
"Drink it all."
Her eyes squeezed shut, tears spilling as she swallowed, her throat milking me with every gulp. Cum leaked from the corners of her lips, dripping onto her chest.
At the same time, her pussy gushed once more, another orgasm tearing through her body as the vibrator hummed inside her ass.
Her body finally went limp, collapsing forward against me. Her face pressed to my stomach, her lips still wrapped loosely around my shaft as she panted for air. Drool and cum mixed, sliding down her chin.
I pulled her up, kissing her messy lips. Her eyes fluttered open, dazed and shining.
"…Souta-kun… I came so hard… from my ass… from my throat… all at once… My mind went blank…"
Kotoha collapsed against me, her body trembling from head to toe. Her chest rose and fell in quick bursts, nipples still hard and red, her thighs glistening with wetness. The vibrator hummed faintly inside her ass until I switched it off and slid it out slowly. She whimpered at the emptiness, but then let out a shaky sigh.
"…Souta-kun… I can't move anymore…"
I placed her on the bed and hugged her against my chest, petting her head gently.
"Better?" I asked softly.
She nodded, eyes fluttering shut. "Mm… feels safe…"
After hugging her for a while, I grabbed a warm towel from the bathroom and wiped her down gently.
I cleaned her chest, her thighs, and finally between her legs, careful with her still-sensitive skin. She blushed at the attention, but didn't resist.
When she was clean, I pulled the sheets over her. Then I slipped in beside her, wrapping an arm around her waist and pulling her close.
She rested her head on my shoulder, her twin tails a little messy, sticking to her damp skin. Her fingers curled weakly against my chest.
"…Souta-kun… thank you… for not leaving me like that…"
"Kotoha, you're important to me."
"Mhmm~♡"
