You keep feeling her up. You're not even focused on the traditionally sexy bits. You start feeling her adorable flat belly, her skinny little arms, her shoulders. You're enjoying all of her in totality. And as your bodies are close together the feeling of her skin against yours, the way your legs rub together, the feeling of her belly under yours. It's all so sexy.
She starts kissing your belly and down to your crotch and between your legs. You love this so much. Even though it reminds you of your lack of penis it's still so great being kissed down there.
She kisses you right on the pee hole and you feel an extreme wave of pleasure building and cascading through your body. It feels like a climax but its through the entire body, you can feel orgasm in your hands and your chest and eyewear. And the onset isn't even pleasure but just being so turned on. This is amazing.
