Explore that vagina for science!

He leaned close and examined the prize placed before him. Karen's brown pussy hair was parted in the middle by her pink lips. They looked moist, so he reached out a finger to touch them. Karen moaned as he gently rubbed them, getting his finger wet. They felt great, soft and puffy, slippery. How Karen reacted to his touch was very arousing; her breathing sped up, she moaned, and her hips wiggled.

"After the first stages of arousal, which we've already past, blood flows into the area, and my body's natural lubrication starts to flow. My lips and clit get full of blood and very sensitive. Unh! Yes!" She shudders again from your touch, and you can see her flush from her face to her belly.

When he touched her clit, her moan got much louder. "Yes! Rub it, John! If a woman's clitoris is stimulated long enough, she'll experience orgasm. Especially if you put your fingers in her as well."

He snorted lightly at her last statement and took the hint, shifting his thumb to take over stroking her clit, and sliding a finger to her slippery pussy entrance. He pushed it in slowly, feeling how wet and hot she was there. When he moved it inside her, Karen wiggled a bit and moaned.

"Two is better," she said between squeaks.

So he added another finger, getting a rhythm going where he thrust his fingers inside her and pull back his thumb across her clit at the same time, and then reverse, pulling his fingers out and sliding his thumb up her clit. Her wiggling and moaning got more vigorous.

"That's it! Perfect! Oh, John!" Karen massaged her breasts and pinched her nipples, as he quickly finger fucked her. Her hips pushed up to take more of his fingers inside her. He kept this up for several minutes, until she shrieked in ecstasy and her body arched severely. She thrashed wildly, and her voice rose and fell as she came. He continued to rub her clit, but he couldn't keep his fingers in her pussy with her violent gyrations.

"I'm coming! John, you're making me come!" Her orgasm settled down, but aftershocks shook her body every minute or so as Karen recovered from her orgasm, panting like a wolf.
