it's her favorite kink
you "tried" to do the right thing. gave her a chance to back out. but you're not turning down a throatfuck for some dude you know even know.
i’m sure they just talked
it wasn' cheating when she touched your arm, or when you went back to her place, or when she took off her shirt. what came next was cheating
she likes playing innocent. blushing every time someone mentions sex. but on her knees in front of you, she's a desperate cockslut.
you would never have guessed that dainty sweet little thing could have such a degenerate whore for a sister.
eyes glazed, drenched in sweat, she turns to you and says "i need to suck cock." after "looking for her boyfriend," you volunteered.
