Everyone. Please help me. I was doing my homework on my desk, then all of a sudden my older sister walks in nonchalantly. She asks me if I need any help, and she wraps her arms around me, feeling up on me. I just said no and ignored it. She giggled and then whispered into my ear "You're so adorable..." then she nibbled on it. I tried to slide my chair away, but she pulled it back, turned it around and got on top of me and before I could say anything, she kissed me. I tried to move away but she was holding my arms still. She then proceeded to lift me from my chair and push me into a wall, still kissing me, holding my hands against the wall. The worst part of it is that I began to like it. I succumbed to my older sister and just lost the will to fight it. She took note of it. She let go of my arms and wrapped them around her hips. She then began to french kiss me. She slid her tongue inside my mouth, slithering it around while pushing her gigantic breasts againt my chest and her leg in between my crotch. After a few minutes, my mother called for her. She slowly broke the kiss, licking her lips clean from my own saliva. "All the things I could do to you..." she whispered sensually again in my ear. "I want you so badly..." Was the last thing she whispered before slowly turning and leaving the room. I just stood there in shock. I couldn't believe my sister had just done that to me. And I'm only 13 years old. She's already 16. But I can't deny the fact that I began to enjoy the whole ordeal. What do I do?
