You and my parents had been friends for as long as I could remember, stopping by at our house, or inviting us over for family dinners. Whenever you and my parents were together, I was too embarrassed to speak, because all I could think of was your body.

Your clothes weren't any more revealing than any of the girls I went to school with, but with the way you carried yourself it was impossible for me to look away. Sometimes you'd catch me trying to get a peek down your shirt at dinner, and I'd immediately turn away, pretending it never happened. Or after, during clean up, I'd look around a corner to spot you bending over, your ass perfectly outlined as my dick stiffened under my pants. Then you'd stand, and I hid, my ears burning at the thought of being discovered.

Recently I decided I need to be out of my house, away from my parents. It's nothing serious, but none of my friends can take me right now. And then I remember you.

It doesn't take much convincing for you to offer me your spare bedroom. As I hang up the phone, all those memories of how horny you'd gotten me come rushing back. I took no time driving to your house, my mind anywhere but on the road.

When you answered the door, your outfit was nothing like what I'd seen you wearing with my parents. Your loose shirt scooped low, and made it clear you weren't wearing a bra underneath. "Short" wasn't a strong enough word for your shorts, which exposed just the curve of where your ass met your legs as you turned to let me in.

As nervous as I was that you'd catch me, I could hardly keep my eyes off your body as you led me to the spare room. Your ass and hips swaying, and your tits rocking unsupported under your shirt, all of it set me on fire. My heart was practically beating out of my chest, and I had a hard-on from the moment you'd opened the door.

And you just smiled at me, while I muttered a nervous thanks.

That night, just knowing that my room was right next to yours was enough to keep me turned on, my cock stiff and begging to be touched at the thought of you laying in bed. Maybe you were in that tiny nightshirt, or maybe you were wearing nothing at all. I touch myself, as quietly as I can manage, but I don't dare cumming. How could I explain the mess? I fall asleep that way, horny and frustrated and praying I don't have a wet dream in the middle of the night.

When I wake the next morning, my cock feels strange, warm and constricted. I pull off the sheets to discover that my boxers are gone, replaced by a pair of pink floral panties, a single bow at the front. Shocked, I reach down to grab at them, only to find that underneath, I've been carefully locked into a chastity device.

Had you done this to me? Heard me rubbing my cock and decided to lock me away from myself? Or was it your plan from the moment I'd called you?

There's my prompt! Obviously it could go a couple of different directions from here, but please let me know if any of this sounds interesting. Also feel free to check out my profile for submissions I've made in the past.
