2T4U/Jack/Raped Melony and Missy/Tiffany's room/After bite and kiss/fucking/Tell her you won't know if you don't try
"I don't know, but we could try. If feels really good if you can fit a boys pee pee in yours."
You lie down and she jumps on your stomach. By the time you recover, she has your cock lined up with her hole. She lowers herself down to sit on it, but it's far too big. Your baby sister is nothing if not determined though and she starts to bounce up and down. Her pink tongue is poking out as she concentrates.
She wobbles a bit and you grab her hips to steady her and you can't help pulling her down. Her face screws up in pain, and you think she is going to give up but then she screams. You nearly scream with her as, with a little pop, the head of your dick slips inside. The pain is difficult to describe. It's like a truck rolled it's tire over your dickhead and parked there. Its like you clamped it between two ice cubes in a vice and frostbite is about to burn off the tip of your cock. The pain is such a challenge to understand, your brain processes it as pleasure. It hurts so much your about to blow your load inside of her after less than a second.
"Hiiiiiieeeeee!" Tiffany's screech is so high pitched you're not sure if you couldn't hear it until now or if you were just too distracted by your own pain. Fuck! If it hurts this much for you what is it like for her? She just continues her dog whistle screech until she runs out of breath and begins again.
Everything is in slow motion. The head of your adult-sized penis id clamped inside your three-year-old sister's vagina and even though it hurts like hell, it's the most erotic thing you could ever imagine.
You need this, now.
