This is a true story of my introduction to sex…I will leave out the age due to how young I was. If you wanna know than pm me and I will tell you. Also if girl on girl/step sister does not interest you please do not read past this story. Our parents had just gotten married about 4 months ago…they were off working odd jobs for the summer to get a little extra money. They left me with my step sister she was five years older than me and they felt that she was old enough to take care of me. Our grandmother was also at work so we were home alone all day. It started out as a game…she called it School. We would work on writing letters and numbers…she was helping me prepare for the next school year. We worked on that for about an hour/hour and a half…when she said that it was the end of the day and time to “go home”…she had me walk to the bathroom while she waited for me in the hallway to walk by on my “way home”…then she grabbed me and took me to the bedroom. I admit I was a little confused as to what was going on. She then told me to hold still and she tied my hands to the bed…she told me not to struggle and not to scream…she was going to give me another lesson but this lesson was on how sisters showed they loved each other. She then pushed my t-shirt up exposing my small nipples that were as hard as little berries…she then took my pants and panties off. She climbed up on the bed and started running her hands around my chest squeezing my small bumps…playing with my nipples pinching them and twisting them…making them harder. She then said that she loves me very much and lowed her mouth to my nipples and sucked one of them into her mouth and started sucking on it. She then let it pop out of her mouth and licked it nipping it with her teeth. I was breathing heavily and really enjoying the feelings that she was causing throughout my body. She treat my other nipple to the same treatment as the other one…sucking it, licking it and nipping it. She then leaned up and kissed me on the lips running her soft tongue over my lips and dipping them inside telling me to open my mouth…once I opened my mouth her tongue darted in and stared licking mine playing with it…she suck on my tongue as she rubbed and pinched both my nipples. Then she kissed down my neck biting the spot between when my neck and shoulder meet sucking hard. She then moved back down to my small little titties and started playing with them again. After she did this for a little while she then started kissing down my body…dipping her tongue into my little belly button…swelling her tongue around it making it tickle…then she opened my legs and leaned down and smelt my private area. She stuck her tongue out and licked up mu pussy like a dog licks its owner. Then she got really into it…she pushed my legs as far open as they would go told me to leave them like that and opened my pussy lips. She licked inside my hole…all around exploring every area…then she sucked my pussy lips into her mouth pulling on then and licking them…afterwards she moved up to the upper part of my private area and sucked my little button in between her teeth…sucking hard and licking her tongue back and forth…this felt so good to me and I couldn’t help but moan out loud and asking for her not to stop…that’s when she stuck one of her fingers in my thrusting deep hard…it hurt but she kept sucking my little button hard and making me feel better almost instantly…she moved her finger in and out of my pee hole…slowly building speed as I got wetter and wetter then she put two fingers in me and the burn from the stretch made my body tighten and something came out of my pee hole. The story doesn’t end here…my sister and I slept together for three years if you want to hear more please let me know. Also, if you guys feel I should use more grown up explicit words please say so…I was advised to use…less explicit words so I took them out. Please comment and let me know what you thing so far.
