I was going to miss my stepsister when she left for university. Partly because she was good company, but mostly because she was all I had cum to since I was a teenager. She was tall, about 5’10, with long blonde hair that accentuated her slender figure. She was thin boobs and an arse that were small but shapely. Over the years she had gotten more comfortable, and I savoured every time she sauntered around the house braless or just in her panties. I would feel my dick grow and throb every time I caught a nipple poke through the fabric of her shirt, or a flash of colour as her panties poked out from under her shirt.
As she got closer to leaving she started to act differently. Sometimes I swore it was all in my head, but deep down I knew it was true. How touchy she’d become, how she began to tease me. I remember one morning she came up behind me and hugged me, her slender arms wrapping around my body. This wasn’t unusual, what was is how she disengaged. As she left her hug she dragged her arms slowly across my chest, gently applying pressure. Then she teased under the collar of my shirt with her fingers, feeling across my chest. She paused for a moment, before leaving with a skip and a giggle.
