Riley stopped for a moment and pulled back a little. This caused a whole new sensation as the bulbous head caught the inside of my anus and pulled it back toward her. I felt like I was getting turned inside out. She added a little more lubricant to the tight hole and pushed back in slowly, sinking just a little more into me. As I loudly groaned, she continued this back and forth action a number of times until I could feel the sensation change. No longer did the muscle feel like it was being pulled back and forth by the invading toy; I could now feel the cock sliding though the tight opening. A few more dollops of spit added helped even more and a few strokes later she seemed to be sliding in and out of me fairly easily.
She had worked about three inches of length into me and I was starting to be able to derive pleasure out of the penetration when she abandoned any amount of gentility remaining in her. In one, swift, stroke, she buried the entire remaining length into my backside. The suddenness of this deep thrust drove all of the air out of my lungs as I let out a large groan.
Faster and faster, she plowed the cock in and out of my ass with abandon, fucking me in the most basic sense. Her wanton invasion drove me to increase the force and tempo of my own thrusts into my wife’s ass causing her to rock back and forth on top of her daughter’s strap-on. In turn, the young woman on the bottom of our stack sped her movements into her mother that I could easily feel bumping into my cock through the thin membrane separating us. All four of us were moaning loudly and panting heavily through the only orifices in our bodies that were empty.
My mind and body were both overflowing with sensory input and I rapidly exploded inside my wife’s ass, collapsing on top of her afterward. A moment later, my step-daughter screamed as she shoved her dildo as deeply as possible into her mother’s pussy and I could feel it pressed tightly against my own cock. Pressed tightly between us and completely stuffed full of cock, my wife made an odd gargling sound as her entire body shook and her sphincter spasmed around the base of my dick. Unlike the rest of us, Riley continued to plow into me steadily. Her pounding was so forceful that all three of us below her were being rocked back and forth. I could hear her breathing getting faster and eventually, after feeling like my ass was being torn apart, she screamed loudly as she bottomed out the large dildo, her hips tightly against my ass.
After a moment when all of us remained motionless catching our breath, Riley Reached down and grabbed a hold of the testicles hanging below her dildo. She lifted herself off of the thick knob that had been stuffed into her vagina, leaving the longer shaft deep inside of me. I extracted myself from the heap of bodies with a popping sound as I withdrew from my wife’s cum-filled ass. Weak at the knees, my wife reached out her hand for support, so that she too, could rise and her sopping pussy made an audible slurp as it slid off of the strap-on that her daughter was wearing. My step-daughter finally stood up and I watched as her fake cock bounced around in front of her. My wife and I both sat down on the boulder, leaving the two girls towering over us. I had to sit a little bit awkwardly given the toy still protruding from my ass.
Riley motioned in my direction. “Look at your husband,” she said to my wife. “See what he likes,” she continued as she pointed to my ass.
My step-daughter then stood directly in front of me, placing the pussy covered strap on against my lips. “Clean me off,” she directed.
I could see my wife watching intently out of the corner of my eye. Her gaze kept shifting between the cock in my ass and the one in my mouth. When I was finally done licking the juiced off of the rubber penis it was withdrawn from my face and I could see that my wife was so turned on that she had been playing with herself while watching.
Riley took hold of her shoulders and lay her down on her back, still running her fingers through her wet slit. The young woman then got onto her hands and knees and stuck her tongue deep into my wife’s slightly gaping ass hole to lick my cum out of it. My step-daughter walked behind her friend and quickly stuffed the strap-on into Riley’s pussy. She fucked her hard and fast while pulling on the clear plug in her ass until Riley screamed in orgasm after only a few minutes. Both toys were removed at the same time, eliciting yet another squeal from the young woman as her holes gaped.
My wife reached upward and removed the harness from her daughter and licked the juices from her swollen vulva. My step-daughter got on her hands and knees next to Riley and called over to me requesting that I mount her. As I entered her hot pussy with my surprisingly still hard dick, I could feel the toy inside of me bouncing and sending reverberations throughout my ass. I was fucking away at the young beauty in front of me when I felt the embedded cock begin to move. Looking back, I saw that my wife had grabbed a hold of it and was using my own movements to fuck my ass as I fucked her daughter. The whole time she continued to stuff her fingers into her cunt.
It didn’t take long before I felt my step-daughter cum around my dick. The clamping of her vaginal walls tightly around me triggered my own orgasm as I pulled out of her to spew my load on her lower back and ass. Riley quickly arrived to lick the mess off of her. My wife pulled the dildo out of my ass causing a sharp, but brief, pain and left my hole gaping.
Realizing that my wife was still going at herself and had not yet cum, all three of us turned our attention to her to finish her off. I was at her left breast, my step-daughter at her right, and Riley was licking at the base of her pussy and her ass hole while my wife continued playing in her pussy with her fingers. Within moments, she orgasmed in an ear shattering scream. tinyurl.com/SexyRiley The four of us disengaged from one another and were lying next to one another giving gentle kisses and caresses as all of us calmed down from our respective orgasms.
After a short while my wife sat up and asked “what the fuck was that all about?”
The statement came as a shock for me. First, because she almost never swore. Second, because I was still assuming that she was aware and probably had manipulated everything that had been occurring recently.
After a moment of awkward silence, it was my step-daughter who spoke up. “Well Mom…you see…you haven’t been the only one that I have been learning from.” She then went on to recount an abridged version of her seduction of me over the past months.
“I have thoroughly enjoyed everything that both of you have taught me,” she continued. “But I thought that it was about time to combine the lessons. I might add that I am really glad that I did because that was awesome.” Turning to Riley, she asked “what about you?”
Riley vigorously nodded her head and commented “absolutely! I can’t remember a better time than what we just shared.”
