Your big sister barges into your room with a mischievous look on her face, and tells you to guess what she's just found hidden in your mum's bedside drawer! A vibrating dildo!! She giggles as she waves it around in your face, teasing you and making you imagine what your mum must get up to with it! Your sister tries all the settings, talking about how it's so much fancier than any toy she owns herself, and saying she can't believe that your mum fucks herself with this every night when the two of you are in bed! She becomes so curious that she even considers trying it, to your shock and disbelief! You can't believe how crazy your sister is being, and you watch in fascination as she turns away slightly and sticks her hand under her dress, inserting it into herself! You can't help yourself, you try to get a better view of what's happening... And your sister notices, laughing at you and teasing you for being a pervert, but relenting and sitting back to let you watch properly! She gives the toy a thorough testing, and after a while notices that you've become aroused - so tells you to go ahead and do what you need to do, she doesn't mind! She giggles and teases you, talking dirty about your mother and her masturbation habits, as the two of you get closer and closer and finally cum together!
