She smiled and murmured, “Wait here for a few minutes and come to my room. I know of a better way you can thank your horny mother.”
My plan was working. Stripping off my clothes, I stroked my hardening cock in anticipation of fucking my hot mother. Less than five minutes later, she called out.
My cock bobbed when I saw her dressed in the black nightie she wore for the trophy wife.
“I see you approve,” Mom seductively said.
“It’s the nightie you wore when I first held your luscious ass in my hands. You can bet I have fond memories from it.”
“Me too. It was the first time I saw my son’s glorious cock. Come here and properly thank your mother.”
Hugging her close, I pressed my staff into her soft belly while we French-kissed. Re-enacting the first time I saw her dressed in this nightie, I moved my hands under her fabric to hold her firm cheeks. Mauling her flesh while we kissed quickly heated us. Bringing my hand to her front, I cupped her hairy mound and slipped two fingers into her slippery slot.
Mom croaked, “I wish you would have done that the first time I wore this, but our client would have left without receiving proper service.”
Mom pulled back and pushed me down to the bed. My cock jerked again when she removed her nightie, displaying her sexy body. She wanted to fuck me cowgirl style; it was perfect. Lisa would walk in and witness Mom riding my hard cock. Wasting no time, Mom straddled me and lowered herself onto my prick.
She humped up and down so fast that I was afraid it would be over before Lisa made it back to witness our incestuous act of love. Mom leaned over so I could suck on her nipples while she rode my cock.
I felt relief when I saw Lisa out of the corner of my eye, undressing while lustfully leering at our union. I humped up, resulting in a loud moan from Mom. Locking her eyes with mine, she cautioned, “Don’t you dare come yet. Let me finish showing Lisa how a mother fucks her son. After I climax, you can fill her pussy with a load of cum.”
Lisa shrieked, “My God, Melissa. Do you have eyes on your backside? I thought I was pretty quiet.” She glared at me, thinking I had told Mom.
“It wasn’t me, Lisa. I think Mom and my wife are connected telepathically. There are no secrets between them.”
Mom increased her pace, leaking more precum when she neared her orgasm. “Twist them, Sam. Send me over the edge. Show Lisa how you take care of your mother.”
She didn’t allow me to reply, locking her mouth on mine. As our tongues battled, I twisted her engorged nipples, causing her pussy to contract and coat my cock. As soon as her convulsions ceased, she pulled off and rested her weight on me.
One of Lisa’s hands squeezed her tit while the other was lodged deep in her slot, witnessing the incestuous act. Mom rolled off and spread her legs out, displaying her dripping slit to Lisa.
Mom looked at Lisa and said, “I hear you’d like to suck on this motherly pussy. And while you’re eating me, my son can finish your doggy fuck. Monica tells me she felt bad for interrupting it the first time.”
Lisa didn’t respond, kneeling on the bed and lowering her mouth to Mom’s hairy hole.
“Wow, Mom!” I exclaimed. “You and Monica know everything the other does. It works for me; I can’t wait to finish our doggy session.”
Positioning behind Lisa, I ran my fingers through her spongy mound. She was already wet from watching Mom and me fuck. My cock was coated with Mom’s juices and easily slid in several inches before Lisa’s tight slot prevented my advancement. Holding her hips tight, my cock pried through her slippery slot until she loosened enough to accommodate my girth. Slowly sliding in deep, my fat head parted her tightly clinging walls and stopped only when my balls slapped against her hairy mound.
She groaned with pleasure when I sawed in and out of her tight canal. Mom was already approaching her orgasm while my cock ravaged Lisa’s pussy. After ten minutes of unrelentingly pounding her sex-starved slot, she increased her humping, nearing her climax.
Lisa reached up to squeeze Mom’s sensitive breasts while sucking her clit. Her fingers gripped and twisted Mom’s sensitive nipples, not realizing the consequences of her actions. Mom’s back arched and flooded Lisa’s mouth with cum. I changed the angle of my stroking to scrape along Lisa’s rough patch, causing her to release Mom’s pussy, screaming out in pleasure.
Once her face was clear of Mom’s hairy pussy, I pushed her up until she buried her head between Mom’s jiggling mounds. Mom wrapped her arms around Lisa’s back to hold her tight, helping her son fuck her to orgasmic bliss. Lisa violently shook, nearing her release.
Mom sensed I was getting close. “Remember the first time you fucked me when I tried to hide my identity? It was a blissful night. I passed out from the excitement. It was the best night of my life.”
Lisa’s walls tightened and convulsed, nearing her climax. My fat head expanded when I recalled the first time I fucked Mom. My balls tingled and filled with hot cum, signaling my impending climax.
Mom continued, “It was one of the most intense orgasms I’ve ever had. There’s nothing more exciting than the sinful act of family fucking. It’s your turn to experience the same illicit pleasure. Fuck your sibling hard! Lisa is my daughter, and you’re fucking your older sister!”
Lisa’s hips thrashed to and fro, threatening to dislodge my prick. Holding on tight, I rammed to the bottom as my first load erupted from my cannon. Lisa screamed, feeling her insides bathed with hot cum. Her pussy contracted tightly when her orgasm overtook her. She milked my cock as I unloaded the rest of my sperm. It was as good as when I fucked Mom. After she relaxed, I stayed buried in her tight slot.
Moving my hands up her sweaty, slippery body, I captured her tits and shoved her up to be face-to-face with Mom. They immediately locked their lips together, sealing their love for each other. My cock softened and fell out of Lisa’s saturated cavern.
Finally recovering from my explosive orgasm, I queried, “Mom? How could this be the first time I’ve heard that Lisa is my sister?”
“It’s a little complicated, dear. I gave birth to Lisa when I was sixteen. Knowing we couldn’t care for her properly, your father and I reluctantly gave her up for adoption. We found a wonderful couple in a much better position to raise her. The adoption papers remained sealed until she turned twenty-one, and I was forbidden to meet her until that time. Remember when we visited Lisa on her birthday? That’s when it occurred to me that she might be my daughter. She was adopted and had the same birth date, and call it what you will, but my mother’s intuition told me I shared a special connection with her.”
“Wow, Mom. That’s unbelievable. Why didn’t you tell me when you knew?”
“I didn’t know for sure until I met with her the day after her birthday. I wanted to explain in person rather than have her find out through the legal system. We talked at length and agreed we’d keep it to ourselves until the proper time. Monica, Lisa, and I felt tonight would be perfect for our family joining.”
“Monica knew?”
