Mark and I went with our friends, Susan and Tom, to a party hosted by two guys I knew, Paul and Aaron. It was ok. We had a lot to drink, and I had a good time.
The party was in their apartment. The apartment was small, with just two bedrooms, one bathroom, and the main room that also doubled as the kitchen and dining room. It was a pretty typical college apartment.
I had to pee, so I used the bathroom. I noticed that one wall had three circular holes cut in a row. The center hole was larger than the other two. A piece of plywood blocked the opening. It looked like the wood came out, and you could stick your head and hands through the holes and lock them like they once did to punish people.
It was kind of intriguing. Mark and I had experimented with light bondage, nothing fancy. I let Mark tie my hands to the headboard when we fooled around. I think he knew how much I liked it. It made me feel so helpless, but I knew that Mark wouldn't do anything I didn't want him to do. With my hands tied, I could only wait in anticipation of his touch and the feel of his penis sliding in me.
I looked closer. A wood piece opened up on a hinge. I carefully swung it open and removed the plywood that blocked the holes. I could see into one of the boy's bedrooms. The hole opened up right over the bed.
I realized that if someone knelt on the bed and poked their head into the hole, they would be in position to be taken from behind. Wow! I had to tell Susan!
I grabbed Susan and showed her what I found. Mark and Tom heard us giggle, and I had to explain it to them as well. Mark suggested that I try it out! I was secretly intrigued, but I was reluctant to let Susan know how much I wanted to.
"Why not try it?" Susan asked. "It's not a big deal. It's not like it would be locked or anything," Susan pointed out.
I pretended to be reluctant, but I knew I had to try it!
Susan walked to the bedroom with me and helped me climb onto the bed. I knelt and stuck my head and hands into the appropriate holes. Mark and Tom gently closed the top half of the board that locked me in but left it loose so I could still get out if I wanted.
I found myself looking right at the boy's crotches! It didn't hurt, but I couldn't get free without pushing the top board up. It was loose enough that it wouldn't be a problem.
The guy's teased me about it, and a few more people at the party came over and watched. I was getting ready to climb out when Aaron, one of the hosts, came over.
"Isn't that weird?" He asked. "The apartment came that way." He explained. "There is a lock in the cabinet for it."
"Did you ever use it with a girl?" I asked him
"I'm not saying, but it is much more intense if someone fools around with you locked in," Aaron said.
Susan found the lock Aaron talked about and slid it through two holes that kept the boards from opening up.
"Stop that! Take it out!" I told Susan. I was starting to get worried but knew I was safe with Mark and my friends. They just wanted to scare me.
"Oh, relax, it's not locked. I just put it in to keep it from opening up. We will let you out in a minute." Susan assured me.
Sure enough, Aaron was right. The top hinge didn't budge with the lock in the hole. I was trapped and helpless until they removed the lock. Someone in the other room could fuck me silly, and there was nothing I could do about it! I should have been scared, but I knew nothing would happen at a party with my friends. I wondered if I could come back later with Mark and borrow the bedroom from the hosts. I felt myself get very aroused.
"Go ahead and go into the other room and feel her up!" Susan told my boyfriend, Mark.
"No! Don't you dare!" I told him, but Mark laughed and walked into the bedroom. I heard him close the door and felt his hands roam over my ass and slide into my shirt. His fingers found my nipples and squeezed. I felt a hand slide over my shorts, between my legs, and rub.
Susan, Tom, Aaron, and a couple of others laughed and watched me grunt as my boyfriend prodded me. His hand slid into my pants and probed. They were slick with my secretions.
"Wow!" One woman said. I didn't know her name. "She is really into it."
"Fuck her!" Susan yelled to Mark. "We want to see you fuck her!"
Susan was drunk and didn't listen to my protests at all. Neither did Mark. I felt him unbutton my shorts and pull them off. Now his fingers slid deeply in and out of my wet pussy. I had a hard time focusing on the people watching me.
I felt Mark remove his fingers and line up his penis, and the delicious feeling as he filled me up. I couldn't believe that he was doing this in front of everyone! I grunted, and despite my best efforts, I responded to his thrusts.
Tom was standing in front of me. I couldn't look up to see his face, but I could see a tent straining against the front of his pants. No one spoke as they watched my boyfriend screw me.
I fought my impending climax but was getting close despite my best efforts.
"Hey! The lock is not closed!" A thin, pretty woman watching next to me said. Before anyone could say anything, she squeezed the lock, which closed with a loud click.
"Well, I didn't know!" She explained when we told her that it wasn't supposed to be locked. "I just thought it came loose. I didn't know it was just there! It shouldn't have been there if it wasn't supposed to be locked! So, just find who has the combination and unlock it."
No one had the combination. I was locked in! Mark kept screwing me, and everyone kept watching. I was trapped and horny, and the whole room smelled like female lust, and I didn't think it was just me.
Finally, I felt Mark finish. As Mark clumsily pulled my underwear and shorts back on, I couldn't look anyone in the eye.
After getting his rocks off, Mark came into the room, mellow and relaxed, and Susan explained the problem.
"Shit!" He said. "What do we do?"
All anyone could think of was to get a bolt cutter from the hardware store, but it was closed and would not be open until tomorrow. He said he would look for one.
I didn't want him to leave me alone, but what could I do? I couldn't stay there all night!
As soon as he left, one of the girls suggested that it would be cool to see how I reacted to a vibrator! I didn't think she was serious, but everyone left the bathroom, and I heard her go with a bunch of people into the room where my ass was.
I gasped when someone pressed something against my shorts, right between my legs! It vibrated strongly! A girl I knew told me about using a vibrator once, but I was never brave enough to buy one. The vibrations were strong and went through my pants like I didn't have them on! I tried not to react, but I couldn't help it.
More people were in the bathroom watching me now. I tried to ignore them, but the feeling was strong, and I was helpless.
Someone unzipped my pants. I felt someone pull them off and cool air against my ass. I should have protested, but I knew they would strip me naked anyway. I didn't see Susan or Tom anywhere.
I felt the vibrator directly on my clit! I moaned and strained against my bounds.
"Wow. She looks like she likes it. I think she is going to cum." I heard one of the women watching me say.
