I'm your sister and you said the taboo relationship we have is over, but I know as your big sister I can always persuade you. You're so crazy about my curves, how I don't wear a bra, how I'm so experienced and naughty. I tell you that I can see by the bulge in your pants that you aren't done wanting me. I tell you that I saw something in porn that I want to try. I tease you with my jiggly tits in my crop top and my big ass in jeans, bending over, twirling, showing off my body and flirting. I encourage you to take your cock out and jerk off for me. Then, laughingly, I tell you what I want, sticking out my tongue, using vulgar language, making your cock even harder. You're kinda grossed out and kinda turned on beyond belief that your slutty sister wants you to lick her asshole. Of course you're willing but don't want to seem over eager, you're so turned on by my ass. I turn around, my butt so bubbly in my jeggings, and peel them down showing off big, round, bare cheeks. I make you kiss them, then lick them...then dive deep. I moan, I spread, I talk dirty, it feels so good and you love to jerk while you lick your sister's dirtiest hole
