I have a best friend that I've been tight with since we were babies, the kind of best friend your mother stuck you in the crib with the day your friend was born. I was always so jealous of my friends small perfect body, even when we were so young it didn't matter. We always had sleep-overs whenever we could, and I would secretly always hope she got fatter or something, but she never did. Always with her perfect body, all I had to attest to was the fact that I went through puberty first and had my breasts before she did. She seemed to be jealous of that though, so I called it even when I caught her staring.
One night we got into a game of truth or dare, it started out innocent, 'who do you have a crush on?', 'I dare you to say 'penis' really loud'. But then my friend pulled something unexpected on me. She picked up a firm decorative pillow and said 'I dare you to hump this for five seconds' I wasn't about to back down because I was going to make her do the same for longer to back at her. So I did the deed and got the strangest feeling, I didn't want to stop, the sensation, seeing the look on her face...so I dared her to do the same, for ten seconds. I laughed out of nervousness when she made little noises, she seemed to have wanted me to dare her to do that, as if it was the only reason she dared me to. That was all for that episode, but upon returning to her house, things got more intense. We skipped all of the innocence and got right down to business.
'I dare you to hump the pillow for 20 seconds' she said, demandingly.
'Yeah, I dare you to do it for 45' I said through a tingling feeling between my legs.
'60!' she yelled, almost sweating from her last dare
Thinking this pillow wasn't hard enough for my taste, I went for something a bit harder hoping she would dare me to do the same. 'I dare you to hump my knee'
It was an almost surreal experience, seeing her over me, her hair moving as she did, she was panting and my heart was going so fast, I felt a wetness and although I was confused by it I welcomed it gladly, but I wanted something more direct, I was horny. For the first time, I was really, really horny. She left a wet spot on my knee and had one through her pyjama pants, and I understood that she got the same wetness and it drove me a little crazy, after she dared me to hump her knee which I did gladly, without even a dare I moved up to her and started to grind my pussy into hers, we were sweating and I put my hand on hers and she giggled, I don't know if I came, but with the squeals and laughing she was doing I'm more than sure she did, I lifted her shirt to see her chest and try to lick her nipple but suddenly she said 'Stop!' I asked her why. She said 'We're only kids'
I'm still friends with her to this day, she still has the perfect body, just now with hips and breasts and sometimes I hope we'll both re-live the experience.
