(This video is a bit cheaper because it's shot on my phone rather than my filming camera!) It's been a couple of days since you and your step-sister fooled around with your strap-on, with her stroking it like it was her dick, and you eventually sucking it whilst you jacked yourself off... Today you walk into her bedroom and interrupt her just about to have some fun with the strap-on again, so you ask to join! She says you're welcome to, but that she was planning on putting a vibrator into her pussy for some added stimulation while she strokes, so are you okay with seeing her do that? You tell her you're fine with that, and watch as she strips off and inserts a small vibrator inside herself before strapping herself into the harness! You pull down your shorts and start stroking your own cock as your step-sister begins playing with hers, rocking in place on the bed as she enjoys the vibrations! The two of you chat as you stroke your cocks together, and your step-sister confesses that she's really enjoying imagining herself as a dude - so she's wondering if you've ever fantasized about being a girl? You say you have wondered about it and thought it would be hot, and your step-sister asks if you've ever pretended to be a girl when your girlfriend is fucking you with the strap-on? You admit that you haven't tried that, and your step-sis insists that you should try that next time, saying it would probably be really hot... As she gets close to cumming from the vibrations she starts dirty talking about how you would imagine that you have a pussy and that it was being filled by a thick, hard cock, pumping in and out of you... She cums hard as she keeps stroking herself, entertaining herself with the thought of you being fucked like that, and when she notices you haven't cum yet, you ask her why not go ahead and try it now? She's confused by what you mean, but you explain that her idea of a girl fucking you with a strap-on while you fantasize about having a pussy - you'd like to try that right now! Your step-sis is thrilled and jumps up, getting you to lay back on the bed and pull your legs back so she can fuck you in missionary! As she slowly slides her cock into your asshole she tells you to pretend it's your pussy, and to focus on how your tight little pussy is being so filled and stretched by her big hard cock... You stroke your own cock as your step-sister fucks you, and it doesn't take too long for you to shoot your load all over yourself as she dirty talks and pounds you! Afterwards, your step-sister admits that was so hot that she needs to make herself cum all over again!
