(This video is a bit cheaper because it's shot on my phone rather than my filming camera!) Your parents are fucking so loudly in their bedroom that you can practically hear it all over the house! You find your sister in the hallway, listening in fascination through the door, and you ask her what she's doing. She jumps when she notices you but laughs and admits she's listening in - doesn't your mom sound like she's having the best time? Your sister asks if you can hear it inside your bedroom as well, since your room is right next to your parents' room. The two of you head into your bedroom and sure enough you can hear your parents fucking even more clearly! You can tell that your sister is getting a bit excited by listening to them, and you tease her about being a pervert over her own mom and dad. Your sister admits she's finding it arousing, and begins fantasising out loud about what your dad must be doing in there, and how big his cock must be to get your mom to make so much noise... Your sister says wouldn't it be hot if they knew the two of you were listening, and they were secretly hoping that you'd like it.. She's getting more and more flustered, and you have to admit that you're getting turned on as well, listening to your mother's moans and screams coming through the wall. Your sister notices your erection and seems pleased, giggling about how naughty it is to be getting so aroused over your mom and dad. She decides she wants to masturbate listening to them, and asks if you'll give her the room for a while. You tell her she should go do that in her own room, but she insists that she can't hear that well from her bedroom, so it needs to be in here! You tell her you're not going to leave her alone in your room, so she suggests that you just do the same as her and jack off - she can see that you're rock hard anyway, so you must want to! You're a bit nervous about jacking off in front of your sister, but after the two of you promise to never bring this up to mom and dad, you agree. Your sister takes off her skirt and starts rubbing her pussy through her knickers, but soon decides just to take them off completely so she can finger herself. You start shyly jacking your cock, and eventually work up the courage to ask your sister to take her top off as well! The two of you masturbate shyly, giggling as you listen to the sounds of your mother getting pounded, until you both cum just as you can hear your mom and dad finally finishing!
