You get home from work and go to ask your sister if she wants to go get some grub with you but something feels off. As you walk in the door you find her on her hands and knees with a mouth wide open on Rovers cock. You aren't letting her off easy this time, if she can do this for the pup why not you too? Shes scared and a little un-willing at first but she knows it'll only be worse if she says no... god if anyone found out what she does in her free time... She opens wide and teases but seeing Rover have all the fun and watching isn't enough. You demand she lets you give her a go too, you won't be able to last long after watching your sister act like a whore anyways. She happily obliges and bends over and lays on her back still sucking puppy off. Video ends with cuteness and embarrassment
