The good thing about the cameras I installed at home was that I could watch them from anywhere with my phone. When I was out of town on business I could still watch Dena at home. Usually when I got back to my hotel room after work, the first thing I did was check the cameras to see what was going on. Most of the time there was alot of nothing going on at this time of day. I had noticed that Dena never masturbated when her mother was home, not that I ever saw anyway. Sometimes as she lay on her bed after school, fully clothed and nose in her phone, I would see her hand exploring herself almost as if unconsciously. But she never got naked and went all out.
After her mother left for work it was a different story. When she masturbated those times it was almost always with her light on and she would get fully naked and really go to town. I suppose knowing she was alone in the house made her secure enough to let it all hang out, so to speak.
I had been out of town for two nights now and the first night I got to watch Dena doing what I just described. I had watched her taking her shower ( I didn't get to see that often when I was at home because she usually showered while her mother was still home). Before she was completely dried off I had already blown a load but I kept watching intently. She left the bathroom and went upstairs to her room. It was just now 10pm so that meant her mother was just leaving for work.
Dena sat on her bed in her thin pajamas, doing whatever it is she does on her phone. She was sitting up against her pillows and had her knees pulled up. She was bouncing one leg back and forth to the side giving me crotch shots each time her leg spread open. I was getting hard again just from this. Her pajama bottoms had creeped up into her crack and she had a noticeable camel toe. It was hypnotic like, watching her leg go in and out flashing her smothered pussy at me over and over. After a little while she sat up on the edge of her bed and began unbottoning her pajama top. She never wore underwear under her pj's. As she undid the last button her soft titties spilled out of her top. I never got tired of seeing those beautiful tits. I had just seen them a little bit ago but was excited to see them again. Dena stood and pulled her bottoms down to her knees and they fell the rest of the way to the floor from there. She stepped over to her dresser and retrieved her vibrating massager. I may have described it before but it is one of the little hand massagers with four legs and little balls at the end of each leg. The balls were about the size of a ping pong ball.
She went back to her bed and lay down on her stomach. Dena wasted no time and raised her ass up and I see the little white massager slide into her pussy from under her. She slid the ball up and down her slit slowly a few times and I could see the wetness shining on it. Now she popped it into her pussy and back out over and over until her hips started bucking. She then quickly stopped and rolled over onto her back. She was laying flat on her back now staring straight up at the ceiling. Her legs were hanging over the edge of the bed and spread wide open. Dena now started running the massager back into her pussy, occasionally pulling it out and rubbing the length of her slit. Her movements were getting faster and she pulled her knees up and let her legs fall to the side and was now spread wide as could be. I watched as her chubby inner thighs started jiggling with her frantic movements. Dena reached one hand down and spread her pussy lips open and with her other hand she pressed the ball of the massager against her exposed clit. I swear I could see her clit get harder as she did that. I looked up to watch her face but the way she was laying and the angle of the camera I couldn't see past her tits. That was OK because I'm now looking at my stepdaughter's amazing tits jostling and bouncing from the workover she was giving her pussy.
I saw Dena's hips start to buck and I knew she was about to go over the edge. I saw her head raise up, her eyes tightly closed mouth open, and she slammed it back to the bed. Her whole body now started covulsing with orgasm. She tossed the massager and plunged two fingers into her pussy while frantically rubbing her clit with her other hand. Now her whole body went stiff, she raised and closed her legs straight out in front of her but kept her hands in between at her pussy. I could see her stomach muscles clenching with with pleasurable orgasm. She rolled to her side, her convulsions slowing and finally stopping altogether. She still had both of her hands clasped between her legs. She lay like that for a moment and then rolled back to her back and sat up. She spread her legs and removed her hands from her pussy.
As Dena leaned over to her nightstand for a towel to wipe her hands I noticed a huge wet spot on her bed sheet she had been sitting in. That's something I've not seen her do before. She may have left wet spots but I had not seen it up to this point.
I proceeded to make my own wet spot and, exhausted now from work and watching Dena, I drifted off to sleep.
The next day after work I went through the same routine of checking cams when I got back to the hotel. Nothing was going on so I went down to the restaurant and had dinner. On my way back to my room I called my wife to see how everything was going. She said all was well and that she and Dena had just got home from shopping. She also informed me that Dena planned to go out with Jack tonight. We said goodnight and hung up and I went back to my room.
Jack.....that's who Dena was seeing at the moment. I don't think they were officially gf & bf, they were just casually dating. I wasn't overly fond of Jack. I'll be honest and say it was mostly because I was jealous. A big part though was because Dena was my stepdaughter ( I loved her as if she were my own) and I was protective of her. A smaller but no less important reason was that he was just an idiot. I just didn't understand his generation, as I'm sure the ones before me felt the same with my generation. He was still an idiot though and I just wasn't going to let myself ever like him, selfish as it was.
I must have missed Dena getting ready for her date. I had been busy with some paperwork and when I next checked the cams I didn't see anything until my wife started getting ready for work. I watched her do her routine and for a while afterwards I left my phone screen on to watch for movement. I remember thinking to see if I can figure out how to get movement notifications on the cam app.
At around midnight I saw movement. I was almost about to doze off and the movement caught my eye and I snapped to. It was the bathroom cam and all I could see was the top of somebodies head. It was no doubt Jack taking a leak. I checked the bedroom cam but there was nobody there. After a minute or so Jack left the bathroom and immediately Dena entered. She must have done her thing on the toilet because I didn't see her for a couple minutes but then I saw her come into frame and go to the sink. She was primping her face and adjusting her hair. When she got it just right she reached under her tits and pushed them up revealing a little more cleavage. I had a little spout of rage because she was doing this for idiot boy.
Dena left the bathroom and I didn't see anything on the cams for a while. I thought to myself they must be making out in the den. I also thought to myself I really hope they're not fucking. Dena is an adult and she can do what she wants but please not with this loser. As I was lost in this train of thought I saw movement on the bedroom cam.
Dena walked in with Jack right behind her. Dena's blouse was undone and her tits were out of the top of her bra. Jack's shirt was completely off. Otherwise they had the rest of their clothes on. Dena dropped to her bed on her back and Jack leaned down over top of her on one knee and they started making out, or rather resumed I guess. Jack's hand went straight to Dena's breast and started massaging it. He squeezed her tit and then traced her already hard nipple with his finger tip. I could see that Dena was kneading his chest from underneath him. Jack stood up and let Dena sit up and helped her the rest of the way out of her top. She then reached behind her back and unclasped her bra letting it fall to her lap.
