Bo and Me, Part 1

by unfastened belts

I'm Lisa, 21, and the first parts of this story weren't very well written or sexy, so don't bother with them. I might re-write them at some point. To sum up what they were about: I was brought up religiously, started masturbating and watching porn when I was 13 and figured out that I might be lesbian at age 14 when I developed a crush for Hanna from school. I told my best friend Sara about it and she offered to kiss me so I could see whether that did anything for me. It did.

One day, I was 14 and my sister Bo was 11, I walked into Bo's room, which you could only enter through mine. She wasn't there but the door was open, which usually meant that our cat Max was in there. I was looking for some stroking and petting, and sure enough, there he was, idling on her bed like it was no one's business.

We shared some quality cuddling and I was about to leave when I looked at the chair next to Bo's bed. It was a baby's chair from when we were much younger and now served as the place for Bo to drop her used clothes before mom fetched them for the washer. What caught my interest was a thong.

I was somewhat upset and picked it up. It wasn't really anything skimpy. It had a cute cat and a ribbon tie on the front part. It wasn't a G-string; it was all cotton, no strings, but very narrow around the waist and bottom. A children's thong.

Me, I didn't have anything of the sort and I was three years older than Bo. I knew mom wouldn't have bought something like this for her, and I suspected where it came from. A friend of grandma's had a granddaughter who was two years older than Bo, and we regularly got the clothes she'd grown out of for Bo. Mom might not yet have sifted through the clothes, so Bo had decided to try it on, not suspecting that maybe mom wasn't going to approve of it.

I was sort of in a trance, not consciously thinking of what I was doing. I stripped off my jeans and panties and put on the thong. It was too small for me, and pulling it up all the way, the narrow bottom part slipped into my crack instead of covering it. It felt sexy, but I also felt uneasy, not only for wearing a thong, but for wearing my little sister's used panties. But that uneasiness made me feel even sexier. I walked around a couple steps, reveling in the feeling for a while. Max watched lazily out of the corner of an eye.

I stripped it off again. While I put on my own panties and jeans again, I thought how awesome it would feel to wear this all day, maybe at school -- being naughty without anyone around me suspecting. That would definitely make me horny. I contemplated stealing the thong. Mom would never know it was gone since she probably didn't know it had been there in the first place. Bo would just think mom had gotten rid of it without telling her so as not to embarrass her. I just had to keep it in a place they wouldn't find it. That would mean I couldn't wash it. For how long could I wear it before it became gross?

I picked it up again, still not really conscious about what I was doing. I turned it inside out and brought the crotch to my nose. It hit me instantly.

Bo had peed in this. The thong wasn't soaking wet, and there were no jeans on her chair, so she was still wearing them. No major accident. It had probably happened while she was doing sports, maybe taking a ball to the belly during soccer practice, or during a major giggling fit; soon enough that she could excuse herself to a bathroom and empty her bladder. Still, it definitely smelled appreciably of her pee. I looked at the gusset and it confirmed what I already knew; it was slightly yellow. No visible signs on the outside, and the smell was fainter there.

Despite my comprehensive investigation, I brought up the gusset to my nose again. It smelled differently from what I'd have expected. I knew the smell of urine from alleyways and underpasses, but that was more pungent and stinging than this. The smell was musky and warm. I actually seemed to like it. I inhaled a couple more times. It was almost addictive. Once again, my conscious thoughts followed the actual action: I was standing in my sister's room, holding her worn panties to my face and inhaling the smell of her pee.

The realization made me feel wrong. At the same time, it made me feel incredibly horny. Without thinking, I went over to my room, stripped off my jeans and panties once more and lay down on my bed. I held Bo's thong to my nose with one hand, stroking myself with the other. Then I thought of something even more dirty and effective: I pulled the thong over my head so that the bottom was on my forehead and the front part went under my chin. The waistband went behind my ears around the side of my head and the gusset was right over my nose. It fit perfectly. When I inhaled, I could not smell anything but Bo. The thought of that and the smell of her got me so aroused that it didn't take me more than a minute to bring myself to one of the most intense orgasms I could recall.

There was no question about it: This thong was now mine, and I would never give it back.
