Caught by my older sister

When I was younger, I had a fascination with women’s underwear. It started with looking at magazines, then moved to the real thing. Well about the only access I had to the real thing was within my family. I never thought to look at my mothers, and anyway my sister was closer to my age, so started to imagine what she was wearing.

At first i’d sneak into her room and just rummage in her underwear drawer. The thrill of this was enough to give me a hard on, but as time passed, i’d steal and item or two to play with in my own time. The feel of my sister’s underwear, silky or lacy was just so exciting. One day I was teasing myself with a black silky thong, and I lost control and blew my load right into them.

Well after so long stealing them I progressed one day to trying them on. Women’s underwear just looked, and, as I found out, felt much more sexy than men’s do. For a while, I’d even go days only wearing my sister knickers.

Well it was the end of one summer, I was 18, and my sister close to 20. She was working so I had the house to myself. Well I got careless. I was wearing a thong of hers all day, and working at home. I finished up, showered and as I thought she was still at work I moved from the shower to her room and rooted in her drawer for a clean, sexy pair. I pulled on a frilly pink thong, and gave myself a few teasing pulls of my cock before letting it calm down. As I turned to return to my own room, my sister walked straight into hers, catching me with my cock in my hand, rising out of her underwear.

A more awkward moment I’ve never experienced. We stood there in silence for what seemed like an age. I spoke first, pleading with her not to tell our parents. She closed the door, and a smile crossed her face. She said straight out that she wouldn’t if I did as she told me. Of course I agreed straight away. Her command was simple, she told me to get onto her bed and to wank into her panties until I came.

I struggled to comprehend her direction as I’d expected something like bribery. My sister said to hurry up and get on the bed so more in stunned silence than meaning to, I lay down. She told me to start pulling myself. Such dirty talk I never thought i’d hear from my sister, but then again this wasn’t the typical meeting of two siblings.

At this stage i’d lost my erection, probably due to shock. Her command had taken me by surprise as i’d not expected it. She asked if I needed to be shown how to? Still confused I muttered something in return. Well next thing I knew my sister was kneeling over me, one leg either side of me, reaching for my manhood. I snapped back to reality, and told her i’d do it. A look of disappointment crossed her face, I think because she hadn’t got to grab my penis.

I started to stroke myself again. It didn’t take long to get hard again. In fact once I was hard I was ready to fill her pink panties with my cum. I told her as much, but then she stopped me saying “not those panties, these ones”. She reached up under her skirt and lowered the pair she was wearing, and tossed them at me.

I caught the white cotton thong with my free hand, they were slightly damp. I swapped them into my other hand and continued to pump away for a few more seconds. I filled her panties with a thick seam of cum. It was a huge relief and flowed over the little material in my hand. I scrunched it up, folded it over and wiped the tip of my cock with it. I looked at my sister who was standing at the end of her bed all this time, wondering what to do next. She told me to give her back her panties. I believed her to be talking about the ones I was still wearing, and went to take them off. She said “not them ones” and pointed at the cum filled ones in my hand. Things couldn’t get and stranger by now so I handed them to her.

She unfolded them, lowered them to the ground, stepped into them and then pulled them up her legs. I looked confused at her. Then she told me she knew i’d been stealing her underwear for months now, but didn’t mind, so long as I did as she asked from time to time. Obviously, with my secret to protect, I agreed. I asked about wearing the cum soaked panties. She responded questioning why I was the only one allowed to have a fetish. I couldn’t argue and began to leave thinking I wasn’t the strangest one in the family! As I reached the door my sister called me. As I turned she tossed a silky thong to me, asking any chance of a fresh load for tomorrow morning?
