Type something.

Nagi eagerly accepts the challenge, feeling flustered by the thought of being dominated and transformed into his girlfriend's feminine plaything. As they begin to compare sizes, he can't help but admire her impressive member, hoping that he might stand a chance against it despite his own small stature.

My girlfriend chuckles softly before she undresses herself revealing her large cock, making me gasp in amazement. I feel so small and insignificant compared to her, but there's a thrill running through my veins as I think about what it would be like to have such power between my legs. She smirks down at me, knowing she has the advantage in this game.

"You're so cute, Nagi," she whispers, running her fingers through my hair. "I can't wait to make you mine." With that, she positions herself between my legs, guiding her massive member towards my entrance. I grip the sheets tightly as she begins to push inside, stretching me impossibly wide and filling me completely with her thick cock.

As she thrusts deeper and deeper, I feel myself being claimed by her, my body growing used to the sensation of being dominated in this way. The pain subsides into a dull ache that only serves to heighten the pleasure coursing through me. "You're mine now," she growls, her pace quickening as she takes control of our lovemaking. "My feminine plaything." I moan in agreement, arching my back off the bed and meeting her thrusts with equal fervor.

With a satisfied grin, my girlfriend slows her thrusts, drawing out our lovemaking until it's almost unbearable. Then, with one powerful push, she plunges deeper than ever before, hitting something inside me that makes me see stars and sends shockwaves of pleasure coursing through my entire body. "There," she breathes, her voice laced with satisfaction. "I made you cum."

Cumming without her touch feels so empty. I want more, need more. My girlfriend notices my pleading expression and laughs softly before leaning down to kiss me passionately, her tongue dancing with mine as she continues thrusting in time with our lips. Her hand grips my cock roughly, jerking it off until I'm on the brink of orgasm again.

I whimper into her kiss, the pleasure building up inside me once more as she brings me closer and closer to orgasm. Her control over my body is absolute; I'm nothing more than a vessel for her pleasure now. And yet, there's something exhilarating about this loss of autonomy, knowing that every sensation is because of her, for her. As my climax crashes over me like a wave, she continues to thrust expertly, milking my orgasm until it fades away into a warm glow.
