This is just a romp into over the top fantasy with some serious nastiness of the anal persuasion at the front end followed by what I think is humorous. It's all dialogue.
"Ooooo! What are you doing back there? Is that your…"
"I'm tonguing your sweet little ass hole."
"You enjoy doing that?"
"Do you like the way it feels?"
"Oh, yeah…sure…feels great. Do you want to put your finger up my butt and…move it in and out?"
"Sure…how about two fingers?"
"Ohhhhh…that feels so nasty…yeah…you're fucking my ass with your fingers…suck my clit while you do that…oh, fuck…I'm going to cum….yesssss!"
"You are one anal erotic little girl and you cum more often than anyone I've ever known."
"That's because you excite me so much and you have such a big cock and it's always so hard…I guess I never really knew I'd like that…oh, my! What's that you just put in there?"
"The tip of my cock."
"Oh, my God! That's bigger than your fingers….uh…uh…oh, shit!"
"How's it feel?"
"Funny…strange…burned a little there for a second…oh!"
"That was the head of my dick pushing through…the head of my cock is in your ass."
"Don't stop playing with my bare little pussy…okay…do you want to shove it in more?"
"Uh, huh."
"Okay…just go slow…let me get used to it…are you in yet?"
"Almost…just a little more…there!"
"Okay, move slow now, go ahead…oh, I like the way it feels when you go all the way in…so deep! Ohhhhh! That feels nice…do you like the way that feels…my tight little ass hole squeezing your big fat cock?"
"Oh….yeah…you know it!"
"Okay…that really feels good! I can't believe what I've been missing! Go ahead now…do it faster…fuck me up the ass…cum in my ass, baby…oh, I love this! It's almost better than the regular way! Oh, God! You're going to make me cum again! Oh, baby, cum for me! Dump a hot load deep inside my tight little butt hole! That's right…yes…yes...oh, my God! So good…love it in the ass…never knew…"
"So…you liked it?"
"Oh, baby! Can we do it like that mean…I mean like all the time? I know how much you like it when I suck your cock…swallow your cum---so yummy! And I still want your big dick in my little cunt but…maybe I could blow you in the morning before we go to work, we could do it the regular way at lunch and then when we come home at the end of the day, you could, you know…fuck my tight little ass?"
"Well, I suppose."
"I know I talk a lot when I'm fucking…I can get pretty nasty…you don't mind, do you?"
"No…not in the least."
"Good! Because I love it when you do the same thing for me…tell me what a hot little fuck I am…wow! You make me such a happy girl…and keep me so well fucked! Now what was this whole serious thing you said we needed to talk about? Oh, before that…maybe next time you'd like me to lick your ass…tongue fuck you back there?"
"You'd do that?"
"Only seems fair. Oh, by the way, I almost forgot. My younger sister---she's the cutest one in the family---is going to be in town next week and I was hoping she could stay here for a couple of nights."
"It's a pretty small apartment and there's only one bed; I never got around to buying a bed for the guess room."
"Oh, I'm sure she won't mind! There's lots of room in this big king size bed for three…if you don't mind. Mindy is a little wild and uninhibited and I'm sure she still doesn't own a pair of pajamas but I'm sure we can manage."
"Well, okay…I guess. How many sisters do you have again?"
"Three. I love ‘em to death but my sisters are all a little wild if I do say so myself---just like our mom."
"Your mom?"
"You met her briefly."
"Your mom is…hot! She doesn't look old enough to be your mom."
"She thought you were pretty hot too. We don't really have any secrets…she told me in no uncertain terms that she wouldn't mind…you know…sleeping with you."
"Does that bother you?"
"Oh, heavens, no! As I told you before, we have no secrets…we share everything…and I mean everything."
"Okay."
