2T4U/Jack/Shower/Ban Aaron/Let her keep exploring on her own
The perversity of her innocent exploration of your penis is arousing enough on its own. You decide to just let her continue on her own and see how this plays out.
“It feels funny,” she remarks, carefully gripping your shaft from various angles with her small, soft hands. You can't believe you're actually letting your 6-year-old sister play with your cock like this. She begins to giggle as she squeezes along the length, feeling it throb and pulse in response to her touches.
"Why does it keep jumping like that?" she asks.
"That just means it's excited," you explain.
"Excited?" she laughs. "Why is it excited?"
You're having trouble focusing on the conversation as her fondling (along with the sight of her naked body) is starting to bring you closer to cumming.
"It feels good when you touch it," you explain breathlessly.
"Really?" she ponders this while continuing to play with your penis like a new toy.
If she keeps this up you'll be shooting ropes all over her face, chest and belly within the next minute.
