I just love the feeling of not wearing a bra or panties. I first did it just at home alone, but nowadays I do it somewhat often. I don't have really large breasts, so I can get away with it when I want to.
No matter what I'm wearing, I've always enjoyed opening my legs a little bit too far (for a particular situation...) sometimes to enjoy the attention of a guy, and sometimes just to enjoy the UNladylike experience of it. I'm not slutty at all, but I enjoy the slutty-ish feelings that accompany the things I do to tease myself.
Even when nobody is around it's a fantastic thrill to open my knees. I like to go to department stores and crouch down with my legs open, sometimes really far and be able to feel my pussy open up. Sometimes I pull my panties to the side, and a few times I actually took them off, right in a store. Very, very unladylike.
I think it all started back when I began shaving my pussy. The first time I couldn't stop looking at it and touching it. I have heard girls say it's creepy because they think it looks like a child down there with no hair, but I disagree completely. I really like how my labia are visible, and how the air feels when I don't wear panties. I haven't had a pubic hair for over five years, and I will never go back.
So anyway, yeah, that makes it better when I spread my legs, feeling my lips open up and feeling them jiggle a little bit as they hang. A lot of times I will be nude or just bottomless when I'm home alone, and even just watching tv I splay out on my couch and enjoy the feeling.
Once I was feeling particularly experimental, back in college late one night at the library, and I knew I was alone on that floor, so I started touching and teasing myself (not full on fingering though) and I was getting VERY horny, and I got up on the wooden table and pulled my skirt up and squatted down, kind of leaning backwards, and I spread my legs really far with my pussy pointing at the entrance door. I just stayed there as long as I had the courage, and played with my lips and breasts (over my shirt). It was extremely hot. I didn't want to get caught, and actually I was super scared that I might, but it was so thrilling that I did it anyway. It was almost 10pm anyway so I knew no one would be coming in.
I like to drive with my left foot on the seat, and my thighs spread as far as possible. Sometimes guys will stare, but most people don't look.
One of my favorite things is tanning, either at the beach or at the community pool at my apartment neighborhood. I haven't been caught with straight up 'spread eagle' but I've had lots of guys stare at me with my legs open quite a bit further than what is socially acceptable. I love it. And I'm not gay, or bi, or even curious, but it is always a little extra thrilling when I see women looking.
Maybe I'll post more later, I have to work soon.
