I'm all alone in my room, super horny and playing with myself. Suddenly my door opens and my sister walks in! She didn’t realize I was in my room! She asks if I came home early just masturbate. She asks if the way I was masturbating actually gets me off? I mean sometimes it does but not always, sometimes it’s hard. She offers to teach me how to touch myself in a better way! She touches my leg gently and says she wishes she had a big sister to show her the ropes when she was younger. She tells me I should take my panties off...I’m a little hesitant but slide my panties off and show her how I usually rub my clit, what feels good. She shows me how getting my pussy a little more wet makes it feel so much better. She licks her finger and starts rubbing my clit and oh wow it feels amazing, but I can’t believe we are doing this. She asks if I’ve ever tried sliding a finger inside but I say I’ve always been too nervous. She slowly slides her finger inside and starts rubbing my clit and it feels so fucking good. She can feel how wet my pussy is getting and I even taste myself off her fingers. I thrust against her.. I can’t believe I’ve never figured this out before. *** My sister suddenly has an idea, she tells me to keep touching myself and leaves for a minute. She comes back with a sex toy! I’ve never seen one in real life before and I’ve just been way too nervous to use one on myself! She turns it on for me and I start touching it to my clit.. it's so intense and feels really good. I’m a little nervous to try the toy inside me but with my sister encouraging me I try it. I pull my tits out of my top too and my sister starts feeling me up and pinching my tits! I like it a little rough too! My sister starts rubbing my clit hard and fast while I fuck myself with the toy. I flip over and start riding the toy while my sister is spanking me! I can’t believe I’m doing this in front of her but it feels so good... should I cum in front of her? She start rubbing my clit faster and I cum so hard all over the toy! That felt so amazing and my sister can even feel my pussy pulsing. She definitely taught me a lot today! Maybe we can start sharing all our toys!
