Her Sister's Panties
Well I'm not taking them off for you. Not yet anyway.
I might keep them on the whole night and just suck you off. Not sure if I want to taste your cum in my mouth though. What would be fair is if you tasted it first. Get yourself leaking precum and start bringing some of it to your mouth with your fingers. The more you taste the better your chances are of cuming in my mouth. Come on, show me it's ok to have cum in my mouth.
Would you like to see my pretty little lips around your cock? Would you like to look into my eyes as you feel yourself release into my warm mouth. I'd roll my tongue around the head of your cock as I looked at you, watching the pleasure I was giving you.
Just keep feeding yourself your cum, I want to know how much you want me to suck you off.
