Keeping an eye on things Pt 3

***This chapter is mostly set up for the next chapters***

Having set up hidden cameras all over the house and watched my younger sisters having lesbian sex, my Mom and Dad having some kinky sex, and then my Dad fucking Mom's sister, Crissy, on the dining room table, I was really looking forward to getting involved somewhere. I was rubbing my dick raw, and I just wanted to fuck everyone in the house- well, the female versions anyway.

My Dad had shagged my Aunt Crissy last Wednesday; they were talking about going up to my Uncle Don's cabin with his daughter from his first marriage. For a "fuck fest," as Dad called it. Uncle Don bought the land and rebuilt the cabin that was there. They put in a couple of large rainwater tanks, dug and trimmed the well, so they had water all year round. It was right across a road from a Federal forest/nature reserve and there's not much of a back fence, as such, and I think I can get up close without being spotted.

On Saturday, I planned an early party to go to, so got out of the house just after lunch. The cabin is about an hour and a half away, so I went up to it. I scouted locations: where to leave the highway, turn onto a road that runs at the back of the cabin's property, and where to park so as not to be seen from the cabin. I wanted to find out how best to approach the cabin without me or my torch being seen. I certainly wasn't going to walk from where I was leaving the car to the cabin in darkness through the trees at the back of the property without some trail. Sure, it's supposed to be flat and smooth but who knows, and what moves around up there at night. There have been no reports of black bears in the area, but I was going to be careful anyway.

I spotted a good place to park the car off the road and made sure it was safe, not likely to attract the attention of passers-by. Reflections of headlights at night could be an issue, but I think I might have a solution. I got access to canvas drop sheets, so if I can convince my boss, George, I could use one over the weekend; he'll let me take it. Drape it over the back of the car, use the doors to hold it in place, that should fix the problem. They are darkish so anyone driving past won't notice it at all. The front of the car will have a bush on either side to conceal it. That should work. Now to get to the cabin.

I had a rough idea of where the cabin was, but there was still plenty of daylight. I brought a bit of wool and a knife so I could mark a trail I could follow; I just hoped no birds or other animals would want to steal it. I got lucky and was able to get right to the side of the cabin with only about twenty feet of open space to cross to get to a window. From here, if the curtain wasn't drawn, I had a good view right into the large open area of the cabin.

The layout was simple, kitchen, lounge and dining areas were all one room, with the back of the cabin divided into smallish rooms and a bathroom. Indoor plumbing here, septic tank for overflow, so if they were all fucking, then it was going to be in the common area.

I went back to the car, satisfied with my trail, so I went to the cabin again, marking the trail, making sure I would find it at night, in a weeks time. I headed back to a small town near the cabin and stopped at the local diner got something to eat. I sat and relaxed, knowing that if everything worked out, then I would get laid pretty soon. If it didn't, I'd probably have to leave home, oh well, them's the breaks. I was fully confident my plan would work, as long as I didn't get caught at the cabin.

My sisters were playing again, and I had nice videos of them fingering each other, eating each other, making each other cum, three times in that week. The other nights they would just hug and kiss, touch each other a little, then fall into their own beds and sleep.

Mom and Dad had sex twice that week, Monday and Wednesday. Aunt Crissy didn't appear again that week, but the conversations between Mom and Dad were simply, "Be patient, save your energy and your juices." There was something I was missing, it couldn't just be about Crissy and Jill, but I'm sure I'll find out.

The week passed slowly, I worked and did everything like I was supposed to. My boss, George, said he was happy with what I had done to finish a big job early on Friday, so gave me the rest of the afternoon off and the ground sheets I asked for. Suited me, so went home, to prepare for my next evening's adventure.

I wasn't really paying attention when I got home. There was a car out front of our home, so parked behind it. Went inside without trying to be quiet but as I went to close the door, I heard a moan. I thought I knew that sound, Caitlin. They're home early, I thought. Then I heard a strange voice, one I didn't recognize, a girl's voice, "Oh yeah, lick me!"

Had to be coming from the girl's room. I took my boots off, and stepped quietly towards their room. I heard another voice, Amelia: "Ohhh, fuck me!" What the fuck is going on there? Well, as if I didn't know.

I got to the bedroom door and it was wide open. That's why I could hear them - open doors don't block sounds. I put my head around the corner to catch a glimpse of what was happening. Jeezz-usss!

Three women were naked, on the floor of the room. Caitlin was lying on her back and this blonde girl was straddling her face. I didn't know who she was, but she had a seriously nice pair of tits. Amelia was also straddling Caitlin and she was bouncing up and down on her sister. I assumed she had a strap-on dildo ramming into her pussy, but I wasn't quite at the right angle to see it.

I snuck back to my room and grabbed my video camera. I know I'm recording it with my voyeur system, but I wanted this for some blackmail, maybe setting it up. I thought this might be a good opportunity to practice taking a video without being seen. I turned it on and set the view screen so I could see where I had to aim the camera to get the action. Standing to one side of the doorway, I started shooting and poked the camera around the door jamb. I got a good sighting, so I watched the screen.

That worked really well; I could see Amelia's tits bouncing in time with her ramming the dildo into her. The other girl was starting to rock her pussy on Caitlin's mouth, moaning loudly now. "Cumming, CUMMING!" She cried and her body shook and she moaned as she fell forward onto her hands. "OOOOHHHH!" And "Fuck!" all sorts of other noises. She eased herself off Caitlin's face and turned back to kiss her.

She turned her ass to the camera and I got this great shot of her pussy. Oh yeah, maybe I can get to fuck that one too. In the meantime, Amelia started rocking her pelvis on Caitlin, and she too took herself over the top, moaning her cum. She leaned forward and kissed both this girl and Caitlin.

"I love what you guys do to me," she said. "Can we do it more often?"

"I wish," replied Amelia, "But I'm not sure Mom and Dad would understand."

"Or Mark," Caitlin butted in.

That was my cue, I thought. "What wouldn't I understand?" I asked, appearing like magic in the doorway. I had the camera behind me so they wouldn't see it. "Hello, whoever you are."

They all just freaked. They tried to cover themselves up, hands flew everywhere. Caitlin grabbed the blanket on her bed and pulled it towards them.

"Oh, you fucking asshole!" Caitlin cried, amid the screams of the other two, "Fucking pervert!"

"Oh, I'm sorry," replied calmly, "Obviously I've upset you. I'm going to go have a shower while you calm down and get dressed. We'll talk after, okay?" I didn't give them a chance to respond apart from the squawks and cries of asshole and pervert left behind me. If only they knew the truth. They are right, but I wasn't going to let them know that.

I quickly went to my room, hooked the camera to my computer and prepared for the shower while the card was being copied. I thought about it a bit and asked myself if I really had the balls to blackmail them. I stripped to my boxers, put my light bathrobe on and after the copying finished, took the SD card out of the camera and went back to the girls' room. I wanted their cooperation, their love, not their hate, I thought. The door was shut, so I knocked. The noise from inside stopped.

"What do ya want?" came a harsh response.

"I have something for you," I replied. "It's the video I shot while watching you." The door didn't open, but nothing was said. "Look, I'm going to slide the card under the door. It's a high-density microSD card. I know you can watch it on your computer, just so you know you've got the right card, okay?" I didn't expect a reply but slid the card under the door as best I could, turned and went to the shower.

I didn't lock the door, didn't think I had to. Started the shower, stripped naked and when warm enough, stepped in. We have a colored glass sliding door that is something of a privacy screen. It's not completely translucent, and it distorts any image so that you can see someone else in the bathroom and they can't see a clear image of you.

I felt, rather than heard, the bathroom door open, interesting, I thought. I couldn't see who it was, but was hoping they were unarmed.

"Mark?" I heard the stranger.

"Yes." I mean, who else was it going to be?

"Can I come in with you?" My cock immediately jumped to attention.

I opened the door and looked at this lovely, naked woman. She had a thatch of sandy hair on her pussy, and nice tits, not big, but nice for her body. She looked at me, and my dick stood out proudly.

"I'm afraid I don't fuck on first dates," I said, controlling myself. I really wanted to reach out and pull her in, but I resisted, because this wasn't the way I wanted it to go. I wanted the girls to know I wasn't going to blackmail them, but for them to come to my bed willingly. If blackmail was the only way it was going to happen, then so be it, but I had bigger fish to fry this weekend.

Her eyes popped as she looked at me, but I'm not sure whether it was me rejecting her, or the size of my dick that she was clearly looking at.

"What-"

I held my hand up. "Who are you?"

"I'm Luna," she said, somewhat tremulously.

"Luna, please go back to my sisters and tell them this. I don't care; they can do whatever, whomever, they like. But we'll talk about this more maybe Saturday night when I get home or Sunday. Are you staying for the weekend?"

"I can come back, if you like." I could see she was deathly afraid.

"That'd be nice, but I'm busy Saturday night, so we'll talk, maybe, late Saturday night or Sunday morning. Okay?"

She nodded and I stepped back, closing the door. Where this self-control came from, I have no fucking idea. I was making this up on the fly now and I really hoped I wasn't fucking it up. The bathroom door opened and closed. I started stroking my dick, thinking about what I had just sent out, fucking idiot, I thought.

A few moments later, the door opened again. "I thought I said I don't fuck on first dates?"

"Yeah, so Luna said," I heard Caitlin say.

"Please, I'm trying to shower here."

"I'm trying to figure out your game here. Why are you being so nice about this?"

"I'm not being nice, I'm being realistic," I said. "And I really don't want to talk about this right now. I need to think about it a bit."

She opened the shower door and looked at my still hard dick. She was only wearing a pair of panties, and that was unexpected. She has really nice tits. I know they wear a 34C cup bra, and this is the first time I've seen them in the flesh.

"Thinking about that bit, I expect. She got that right, horny, are you?"

"Look, Caitlin, I know this might be hard for you to understand right now. Yes, I am a perv; watching you guys go at it was unbelievably sexy. And Luna, she is so pretty, but not as gorgeous as you guys."

"So you want to fuck us, then?"

"I'd love to, but only if you're willing and being blackmailed is not going to make you willing."

"What makes you think we'd fuck our brother?"

"Well, you obviously fuck each other, so why not me too?"

"Oh for fuck's sake, next you'll be wanting us to fuck Dad!"

"What's the difference between you fucking each other and fucking me?" I deliberately didn't go down this path.

"We're masturbating! You do it? Spank the monkey!"

That threw me off. Masturbating, totally unexpected. I turned away from her and said, "You can stay and watch, or you can go, one of the two." I took hold of my now half-hard cock and started running my hand up and down it. It grew, but Caitlin didn't move.

I stroked and knowing she was watching, I didn't do anything fancy, didn't even look at her. It was a real turn-on. I was being a total exhibitionist. I never thought I could do anything like this, but I did. It wasn't long and I could feel the tingling in my balls and then in the knob. It grew as my strokes got faster, my breathing stalled, and then I felt my nuts just convulse, my cock throbbed and a stream of white juice shot out the end, onto the wall of the shower. A second shot quickly followed, also hitting the wall as I kept stroking. Then a third pulse, but that arched onto the floor.

The running water quickly washed it away and I wiped my hand over the cum that was on the wall, washing that down. Caitlin was standing watching, and didn't say a thing. I turned and said, "That was masturbating, and I'd really loved for you to have done that for me."

She still said nothing, but turned away and left the bathroom.

I hope I hadn't fucked it all up. I really didn't want to blackmail them, but I will if I have to.
