I play the role of your little step-sister, who you walk in to find licking and sucking a popsicle in just her top and undies. I explain that I have an oral fixation (this is a real thing, I struggle with it irl), and that sucking on something really helps. Not being able to control your urges, you ask me to go on my knees and lick and suck your cock, which I’m very excited to do as the innocent and praise-starved little step-sister I am. As I suck your cock (POV, on knees) I tell you all about my oral fixation, what sort of things I like to put in my mouth (all real) and a detailed story of my P.E. teacher making me suck his dick without my knowledge (fantasy, not real). I act very dumb and naive, constantly asking for approval and asking if I’m doing well, not realizing what’s actually happening. There's more talking than sucking. Ends in a huge simulated cumshot.
