First Time in a Viewing Booth

I had always heard about porn shops having booths in the back to watch videos, but I had never really thought about it since everything is available online and you can watch it whenever you want. A few nights ago, however, i was thinking about it and got curious. I knew there was a shop not too far from here that had them, and after going back and forth for a few minutes I decided just to go for it. I dressed light and drove there and, surprisingly, there were a few cars parked in the lot. When I was inside I only saw two people shopping, so there had to be a couple booths in use. I walked around for a bit looking around when I saw a sign on the ceiling pointing to them. I went up and asked the cashier about them, and she said they were only available to people who bought a disc, obviously because they don't want to hand them out and have to take them back. I went and looked at some of the movies and picked out a cheap one and went to pay. It was a little unnerving when she looked at it and saw that it was a foot fetish DVD, but I figured she's seen some really weird stuff before anyway. She then told me about the rules of the booths, the biggest ones being that if a curtain is closed it's occupied, you have to use a condom and only one person to a booth. I then made my way to the back and saw that there were a couple of curtains closed with low sound coming from them. I picked one, closed the curtain and put in the disc. I watched for a few minutes and I really started getting turned on when a scene came up with two girls, both naked and sucking each others' toes. I pulled off my shirt and shorts, leaving me naked except for my sandals. I kept them on because I didn't know what was on the floor...yuck. I started stroking a little bit until I was hard, then grabbed a condom from the bowl and rolled it on. I was pretty focused on the movie and I knew it wasn't going to take me long to cum, and pretty soon I tensed up and came hard. After a few seconds of stroking and squeezing I pulled if off and tossed it in the trash, then wiped off the rest with a paper towel. I figured since I came all the way down one wasn't enough, so I kept watching until I felt like I could go again. I skipped around until I found a scene where a chubby girl wearing nothing but leather flip flops was rolling around on a couch masturbating with a large vibrator. I grabbed another condom and started stroking again, but this time I decided to slide the curtain open a few inches. I could see perfectly if anyone was walking by and anyone could see in. I turned a little to where I was basically pointing the gap, and after a few minutes someone walked by, and then stepped back and looked in. I knew they were there and glanced over a bit, but then went back to watching my movie. My heart was pounding just knowing that this complete stranger was watching me masturbate, but it made every stroke feel that much better. The girl on the screen was really into it, laying on her back with the vibe shoved deep inside her, one of her feet pulled up and was licking and sucking her own toes. I started whispering to myself 'mmm...suck your toes...yeah, lick and suck your fucking toes...oh I'm gonna cum, cum all over your bare feet...' I glanced over again and he was still there, so I spun a little and put one foot up against the wall, leaving myself fully exposed to him, and after a few more hard jerks I came again in front of him. I milked out the last few drops and sat there catching my breath, my cock softening and flopped over onto my leg. He watched me pull it off and then walked away, and after I cleaned up I got dressed and took my disc with me. I'm not sure that I would do it again, but I know if I want to masturbate in a public place again, I know where to go.
