Stepbro's girlfriend hasn't touched him in months, and I could see it written all over his face — pure frustration, pure need. "You don't have to keep struggling alone," his stepsis whispered, getting closer. "Let me show you what you've been missing." Stepsis guided his hand, talking him through every stroke, comparing herself to what he's been missing — bigger tits, tighter pussy, better in every way than his girlfriend ever was. By the end, stepsis wants every drop, begging him to fill her up and breed her right there — proof of exactly who satisfied him best.
