Chris finds it hard not to stare at his step sister as she moans and thrusts the dildo into her wet pussy. Her small hands grip onto the chair for support, her face contorted in pleasure. He can see how much she's enjoying herself and feels a mixture of arousal and embarrassment.

"Chris..." She moans, her voice barely audible over the sound of her own movements. "I-I can't... I need you..." Her words trail off as she reaches her climax, her body shuddering violently around the dildo.

Hitomi gasps for air, her chest rising and falling rapidly as she tries to regain her composure. She nods, her cheeks flushed and eyes pleading with him. "Please... I need you inside me..."

Without hesitation, Chris steps forward and pushes Hitomi back onto the bed. He kicks off his pants and underwear, revealing his already hard cock. She watches him intently as he positions himself between her legs. "Are you sure?" he asks again, his voice hoarse with desire.

"Yes..." she whispers, her eyes closing tightly. "Just do it... I want your baby." Her words fuel Chris's lust even more as he finally thrusts into his step sister. The sensation of being filled by him is so intense that she cries out, arching her back off the bed.

Chris starts moving slowly at first, letting Hitomi adjust to his size before picking up speed and power. He grabs onto her hips, holding her steady as he pumps into her over and over again.

The sensation of being taken so roughly by Chris is overwhelming, sending waves of pleasure coursing through her body. She digs her nails into his shoulders, urging him on as she feels herself growing closer to another orgasm. "Yes... harder..." she pants, the words barely audible above the slapping of their skin.

As they continue to fuck, Chris begins to feel the familiar tightening in his groin that tells him he's close too.

When Chris feels himself about to cum, he pulls out and quickly rolls her onto her stomach. He positions himself behind her, one hand gripping her hip and the other holding his cock as he thrusts into her from behind. "Cum for me, Chris..." she moans, feeling him push deeper with each stroke.

The sensation of being filled by Chris's cum is almost too much to bear, but it feels so good at the same time. She arches her back off the bed, her nails scratching at the sheets as she tries to find purchase in the intense pleasure coursing through her body.

As he empties himself inside of her, Chris collapses onto her back, panting heavily. For a moment they just lie there, catching their breath and savoring the connection they've shared.

Looking up at him with a mixture of love and lust in her eyes, Hitomi whispers, "Yes... I wanted this." She reaches down to stroke his cheek gently before leaning forward and kissing him softly on the lips. "Thank you..." she murmurs against his mouth as they lie together.

The afterglow of their lovemaking washes over them both, leaving them feeling content and connected in a way they never have before.

As the days go by, Chris and Hitomi continue to share this intimate connection. She's careful to hide her frequent masturbation sessions from him, knowing that he wouldn't approve. But she can't deny the desire that burns inside her whenever she thinks about him.

One night, as they lie together in bed, Chris's hand accidentally brushes against her breast. Startled by the sensation, Hitomi looks up at him with a mixture of embarrassment and longing. "Chris..."

Her voice is barely audible over the sound of their labored breathing as they've just finished another round of passionate lovemaking. Chris hesitates for a moment before slowly wrapping his hand around her breast, massaging it gently. "What is it?" he whispers, already knowing the answer but not quite believing it.

Hitomi closes her eyes and moans softly as she feels his touch, her body arching into him. "I just... I need you..." She pauses for a moment before adding, "

"Please, Chris... I want to feel you inside me again." Her words are almost pleading as she reaches between them and guides his cock towards her wet entrance.

Chris hesitates for just a moment longer before giving in to the desire that burns within him. He pushes slowly into her, feeling the tightness of her body surrounding him. As they begin to move together once more, Hitomi's moans fill the room and Chris can feel himself losing control again.

As their lovemaking intensifies, so does the need for impregnation. Hitomi arches her back off the bed, her nails digging into his shoulders as she feels herself getting closer and closer to orgasm. "Chris..." she whispers, "I'm close... I need you to cum inside me..."

Her words send Chris over the edge and with a loud groan he releases himself deep within her.

As their bodies convulse together in shared ecstasy, Hitomi feels the first telltale twinge of release from her womb. She gasps, knowing that this is it - she's pregnant with Chris's child. A feeling of triumph and victory washes over her as she lays there, spent but satisfied.

Chris collapses onto the bed next to her, breathing heavily as he comes down from his own high. For a moment they just lie there, eyes closed, savoring the afterglow of their lovemaking.
