"Nice to meet you"

Your sister simply smiles and says, "Nice to meet you, and to greet you personally!" before shoving her dildo into your cunt. You moan as she turns the dildo's vibrating feature up to high, and you fall backwards onto the bed. Your legs involuntarily close around her hand as she presses the dildo into you, trying to make as much contact with your clit as she can.

"Oooh, she's a squirmer!" Amy remarks as you flail around wildly and push yourself away from the over-stimulating vibrator. Your sister lets you pull away from it and pulls the dildo out of you and immediately plunges it into Amy, who shrieks her delight. "Oh, fuuuuuuuuck!"

You watch, almost surreally, as your sister continues to stimulate her friend and begins stripping herself with her free hand. Once she's naked, she pulls the dildo from Amy with an audible 'pop' and pushes it back into you, eliciting a shriek of your own. You immediately push back saying, "I can't take any more!"

Luckily, your sister relents and pulls it out, but she holds the dildo out to you, saying "Now you do me!"
