Slip a finger in my asshole.

As you lick and kiss my anus, I grab my tits through my dress and groan, "Oh yeeaahh... lick it you fucking dirty boy." You take this as a pretty good sign that I like all this attention to my asshole. You slip one of your fingers in my pussy, which is dripping wet by now. You finger my pussy while you lick my ass, making me quiver and making your finger slippery. Then you pull that finger out of my pussy, and press it into my asshole. You taste the pussy juice from your finger as it slips past your tongue and into my little butthole.

You finger slides right into me without much resistance. I let out a loud sighing breath as I feel your finger going up my butt. You get your finger all the in my hot asshole, and I reach down with one hand and start rubbing my juices all over my clit. We haven't even gotten my dress off yet, you're already fingering my ass while I masturbate in your bed. This is a fun night.
