Spying on your scantily clad sister has some surprising benefits... Your sister has always worn pretty skimpy clothes around the house when your dad isn't home to nag her. You shouldn't look at her the way you do, you know that. How could you have possibly predicted how she would react when you told her to get dressed? She thinks your joking at first. Just praticing your impression of your dad. Till she looks down and sees your cock imprint in your pants. She yells at you to get out... but she just can't stop looking at it. Maybe having your sister touch your cock will remind your horny brain that she's your sister, you'd be a freak to want your sister touching your cock. Only that doesn't work. Your still hard and twitching in her hand. She'll rub your cock. Just this once. She can't help but run her mouth, she's maybe a little too good and makes you blow early... all over her. Well, you're fucked now, time to pay up. Time to eat her pussy, then you can both be done with this forever. Make her cum then never talk about this again. ...unless you sneakily slide your cock into her pussy and make her feel so good she can't say no to more. Just don't cum in her pussy ok‽ | This sister is switchy: dirty talk follows along with the switching | **this is the 1080 30fps version if you would like the 4k 60fps one drop a rating and I'll send you a link**
