What? You want me to do something naughty? No. It's not right for siblings to do that. But even if we're not related by blood, I wonder if I'd do something naughty. Because you're a pointless masochistic pervert, you see. So you can stroke your penis while watching me do it with another man. I'll watch your face as you frantically jerk off, frustrated as you are. That's right... just looking at that masochistic face of want makes my pussy wet. I'll use that face as a wank and feel great. Ahh... you're a siscon, a masochist, a hopeless pervert, you know... Pervert! Pervert! I'm gonna cum while looking at your perverted face!!
