My step-daughter then came onto the bed behind me and I could feel her bare breasts rub against me back as she grabbed a firm hold of my ass, pushing and pulling it to get me to continue fucking her friend. As I resumed my thrusting motion I felt her moist fingertip press against my ass hole and rub circles around it. Each time I withdrew from Riley, I could feel the finger press even more into me, just shy of penetrating my orifice. It felt good but she was being quite a tease about it and then she suddenly removed her hand from my ass completely bringing it up to my panty stuffed mouth.
Her other arm reached around my chest and she gave a sharp tug on one of my nipples. I felt her lean into me with her breasts firmly pressed into my back as her index and middle fingers of the hand at my mouth shoved my wife’s panties further into me, holding them in place. On my very next backstroke, I felt a firm pressure between my ass cheeks. A brief moment later I felt a sharp pain as I was penetrated by a fairly large object, causing me to groan loudly only to be muted by the panties being forcefully held in my mouth. I felt my cock swell considerably at moment of penetration and after a moment, I began to relax. As soon as I relaxed, the pain subsided and was replaced by an oddly pleasurable sensation that filled my backside completely.
She grabbed a hold of my hips and helped to ‘guide’ me as I thrust in and out of Riley. She kept her own hips relatively still so that each time my penis withdrew, her fake one sunk deeper into my ass. The pressure inside of me was guaranteeing that I would not last very long. I tried to last longer by occasionally stopping but each time I did, I felt an insistent push or pull on my hips. The only good thing was that I could tell that both women in front of me were approaching orgasm as well. Despite being muffled, I could recognize the sounds that my wife was making as those just prior to exploding and Riley had been routinely updating everyone with dirty comments that would make most porn stars blush. The amusing bit to me though, was that, based on those comments, it appeared that she still thought that she was being fucked by my step-daughter, not me.
Sensing that we were all getting close, my step-daughter pushed me to increase the tempo of my thrusts and less than 10 minutes after the four of us were ‘chained’ together I was on the brink of what felt like it would be the most powerful orgasm that I had ever experienced. My breaking point finally came as I heard my wife explode. I buried myself as deeply as possible into Riley’s dripping pussy and felt my step-daughter do similarly to my own ass with her body pressed tightly against mine. I came like a shotgun blast, squirting cum quite forcefully into her womb and she froze in place to begin her own orgasm a moment later.
The feeling of scalding jets of cum filling her pussy made Riley realize that all was not as it had seemed. She craned her neck as far as she could and went bug eyed after catching sight of me. She opened her mouth as if she was about to say something and was quickly stopped by my step-daughter motioning her to remain silent. I then received my own direction in the form of a whisper in my ear saying “get your ass out of here now! Keep quiet, and don’t come back for at least a half an hour.”
Once the statement was made, she pulled the panties from my mouth and quickly backed away from me, pulling out to leave my ass feeling a bit empty. I extracted my own dick from Riley and watched as cum began to ooze out of her. As I got off the bed and went to retrieve my clothing, I finally could see what had been inside of me. She was wearing a very realistic looking strap-on that was about ten inches long and easily as thick, if not a little bit thicker, than my own cock. I thought that it was almost as if I had just fucked myself only a bit longer. I didn’t get an opportunity to see any more because I was being whisked out of the room as quickly and quietly as possible.
As I got my clothes on in the living room I could hear my step-daughter talking to her mother in a domineering way. I couldn’t quite make out what was being said, but could tell from the tone that she was definitely taking charge. I departed the cabin as quietly as possible and decided to check on how the boys were doing. It took me a little bit to find them, but saw that they were having fun with their new friends. After saying hello to everyone, I pulled the boys aside to ask roughly when they expected to return and mentioned that it would be OK if they wanted to invite their friends for dinner either that night or the following as long as we had enough notice to prepare enough food. They said that they would think about it and we parted ways so I wasn’t ‘encroaching’ on their space and embarrassing them.
I returned to the cabin about two in the afternoon, a little less than an hour after I had snuck out and tried to act like I had been gone the whole time. All three women were sitting in the patio chairs underneath a big umbrella with some drinks in front of them. My wife, still looking a little flushed, commented that I had been gone for quite a while and inquired what I had been up to all day. I mentioned that I had taken a good long walk and swim and basically enjoyed the fresh air, sunshine, and exercise. I heard a slight snicker come from one of the girls at the last part and when I looked in their direction, watched as they tried to make it appear that the noise was unrelated to what I had said.
“What about you,” I asked.
“Oh, just spending time with the girls after I finished cleaning up a bit,” was her vague reply.
Raising her glass up, she asked “would you like one?”
I had no idea what they were drinking but replied “sure” anyway.
I sat down as my wife went inside to get me my drink and as soon as she was gone, was bossily told “Mom has no idea that you were here earlier so don’t say anything about it!”
Barely acknowledging her ‘order’ I sternly asked “what the hell is going on around here?”
Sounding more like the parent than the child, she replied curtly “we’ll talk about this later.”
Just then, my wife returned from the cabin with a tall glass in her hand, sitting it down in front of me so I decided that it might be prudent to continue the discussion later.
Thanking her, I took a sip of the drink and was surprised by the taste of a strong gin and tonic. I say surprised because it appeared that we all had the same drink in front of us and although we permit the children to have an occasional small alcoholic drink, it was shocking to see such a tall one in front of each girl, mid-day to boot.
The four of us chatted for a while about this and that, refreshed our drinks, and chatted some more until a few hours later when the boys returned. They each grabbed a soda and joined us, letting me know that it would just be us for dinner this evening. “We invited two of the girls over later tonight though,” one of them stated. One of the other families was leaving tomorrow morning so their children couldn’t come over, leaving just two of the girls able to join us.
