B: Cum walks, bringing me other girls, ass to mouth? You'd do all that?
S: (moaning as she fingers herself harder, rubbing her clit) I'd bring you cousin Kat at next year's Christmas party, suck your cock until it covered my face in cum after you finished fucking her hot ass and wear your cum with pride the rest of the day if you wanted me to, Master. Just please come fuck me! I can't stand to wait anymore; fuck me right now and I'll do whatever you ask! Just please, slam you big fat brotherly cock in my tight pussy and break me and my mind in two!
B: (slams his cock into S's pussy) You weren't lying, your pussy is tight, sis!
S: YYYYYYYEEEEEESSSSSSSS! BBBBBBRRRROOOOOOTTTHHHHEEEERRRRRR! The biggest thing I've had in there is my 6" dildo, so that when you finally did fuck me, it'd be as tight as possible for your big fuck stick!
B: Just like the good Sister Slut that your are! (starts to pound S's pussy hard)
S: Yes Master, I'm the best Sister Slut! (raking her nail's down B's back, causing him to moan) I'm the best because I've trained myself to be the best at pleasing your sexual needs. I have hours of videos I took at college of my sorority sisters and roommates being naked and slutty. I convinced my girlfriend Ashley that she needs to let me hire her a gigolo for her bachelorette party so that we can have an awesome weekend making some big dicked stranger, or should I say you, very happy. (pinches nipples, releasing some milk) I've even started taking hormones to make me lactate because I know how much my Master brother loves to suck on milky titties!
B: (fucking S as hard and as fast as he can) Keep going, Sister Slut. You know how much I love to hear you talk dirty to me. (leans down to suck S's tits)
S: Do my words turn you on, Big Brother? Do you like to hear your horny, slutty sister say nasty things while you fuck her tight wet pussy deeper than she's ever known? (B moans and nods) Things like how those dirty polaroids that you've been getting in the mail are actually me finger fucking your boss's pussy? Or how about that want you to record us and post it online and see how many women beg you to do the same to them; we could track them down and do exactly that.
B: Beg for my cum, slut! Cuz I'm about to fucking blow!
S: Yes Master! Please Master, please can I have your cum shooting so deep into my fertile womb and filling me with so much cum that our daughter will be born pregnant! Please Master brother! Please use your slutty sister with your big fucking cock! I want to squirt so hard as you pound me into the mattress and fill my slutty pussy so full with your yummy cum that the first thing our child knows is the taste of our mixed juices and my voice as I beg you to fuck my ass harder as I give birth to her, spraying you both with my milk!
B: (cumming, slamming as hard as he can with each word) FFFFFFFUUUUUUUCCCCKKKKK! TAKE! IT! ALL! SLUT!
S: YYYYYYEEEEEEESSSSSSS! MMMMAAASSSSSSSTTTEEERRRRRR! (cums)
