You impregnate your best friend's girlfriend

You feel your heart racing as you watch your female classmates undress and lie down on the mats. The sight of their naked bodies sends a wave of lust through you, and you can feel your cock growing harder by the second.

Naomi is lying there, looking nervous but also excited, and you can't help but feel a surge of pride that she is going to have your baby. You approach her slowly and take a deep breath, trying to steady your nerves. You've never had sex before, let alone impregnated a girl, but you know you have to give it your all.

You climb onto the mat and slide between her legs, your cock pulsing with anticipation. Naomi looks up at you with a mix of fear and desire in her eyes, and you lean down to kiss her. Your lips meet, and you can taste the sweetness of her mouth as your tongues dance together.

You start to explore her body with your hands, tracing the curves of her breasts and hips. Naomi moans softly as you touch her, and you can feel her getting wetter by the second. You take that as a good sign and move your hand down to her thighs, spreading them apart gently.

You can see her pussy glistening in the light, and you can't resist running your fingers along the folds, feeling how hot and wet she is. Naomi arches her back and moans louder, and you know you're doing something right.

You position yourself between her legs and slowly slide your cock inside her. She feels so tight and warm around you, and you let out a groan of pleasure as you start to thrust. Naomi grips your arms tightly, her nails digging into your skin, and you can see the pleasure on her face.

You keep thrusting into her, feeling the pleasure building inside me. It's such an incredible feeling to be inside her, and you can feel the pressure building in your balls. You're getting close.

Sorry Masumi! You inwardly apologize to your best friend while raw-dogging his girlfriend.

Naomi is moaning louder now, and you can tell she's close too. You increase the pace of your thrusts, and she starts to writhe beneath you. You can feel the heat and tightness of her pussy as she gets closer and closer to orgasm.

Finally, with a loud cry, she comes, her pussy clenching around you. The sensation is too much for you, and you start to come too, pumping your hot, sticky cum deep inside her.

As you lay there panting, you realize that you've just impregnated your best friend's girlfriend. It's a strange feeling, but also incredibly exciting. You know that it'll complicate things with Masumi, but for now, you're just basking in the afterglow.
