2T4U/Jack/Raped Melony and Missy/Tiffany's room/Ass/Bribe/Force
You don't want to hurt her, but your raging boner needs relief and has taken charge. You use your thumbs to spread her ass cheeks further apart while wiping your precum up and down over her starfish entrance.
"No, No, Not there," she cries, but that only makes you more determined.
"Sorry Squirt. Just relax and let it in."
She keeps struggling and crying complaints as you push the blunt head of your dick hard against the tight entrance. Something has to give and she yells even louder as her sphincter gradually gives up the struggle and begins to open up. You know you should worry about the noise, but you already fucked both her sisters and Mom seems to think it's okay, so you keep pushing.
"Shut up and relax," you snarl as her cries turn to screams and the head of your dick finally pops inside her. Sometimes, when you are masturbating, you grip your dick real hard to delay a cum. Tiff's ass is gripping you much tighter than that, It feels as if it's in a vice, but even though it hurts, it's is a pleasure as well. The sight of your dick planted in your baby sister's ass is a huge turn-on and after holding still for a while, you see if you can push a little more in.
Tiff's shouts have dropped to a whimper now, and she barely reacts as you slide another inch into her. The friction is too much for you and you start pumping spunk. As what seems to be a huge load of baby batter fills her ass, she begins to react and her yells turn into moans. Instead of trying to get away, she is pushing back at you and more and more of your dick disappears inside her. With plenty of spunk for a lubricant and with her relaxing so that your still rampant dick can rearrange her intestines you are amazed to see that the whole thing is now buried in your toddler sister's ass and your balls are banging against her pussy. Not only that, but she is obviously feeling pleasure from it.
Unbelievably, you feel another climax building up and when your three-year-old sister says "more, more" you ram it in as far as it will go as your body shudders to yet another climax. Tiffany responds with a climax of her own and then flops forward in a faint. You wait for your dick to shrink, then, as gently as you can, you slide it out of her tight embrace before lifting her into a cuddle until she comes round.
