I pulled into the driveway around 11:00 and Dad's car was gone. That wasn't much of a surprise, since the sun was out, so he was likely golfing.
Mom was in the kitchen when I stepped through the door. She was in a pink baby doll and no robe over it. She heard me come in and was walking toward me with a friendly smile.
"You're back," she said, reaching up to kiss me. She put her arms around and embraced me, her nipples poking through the nearly see-through material. "I thought you'd never get home," she whispered in my ear, "... lover."
I pulled back in shock, and we stared eye to eye. I felt my cock growing, and tried to respond. "But how..." was all I could get out before Mom continued.
"Do you really think that strange man's dick felt any different than your does? And, while we were playing, your father called his long time friend 'boy'. That's when I knew for sure it was you. That was when my pussy got even wetter."
She moved in to kiss me, and her tongue slipped in my mouth. Our bodies ground into one another, and my cock began pulsing. My hands cupped her ass and I took all her weight in them. Mom raised her legs up, around my hips as we necked.
Her pussy rocked up and down my hardness. She said, "Let's go to bed." I didn't have to be told twice. Mom unhooked her legs from me and we started up the stairs. I froze mid step, and asked, "Does Dad know that you know?"
"Oh, he knows. The baby doll was his idea. He went out so you and I could get reacquainted." We continued up, and into their bedroom, where Mom pulled down the blankets to the foot of the bed, crisp new sheets awaiting our debauchery.
"Now I want to SEE that cock, not just feel it." Mom dropped to her knees and unzipped my pants, reaching inside to find me already responding well to her plan. She looked at the head, no doubt placing how it looked as to how it felt inside her last night. She looked up at me and said, "It's a really good looking cock."
I smiled at her, enjoying her hands exploring my shaft. I realized that this was not going to be the all out blowjob I had expected it to be. This was just part of the discovery of the next phase in her life, and she was in no hurry. We stripped our clothes off and just cuddled into each other, my hardness never waning, her wetness increasing.
"Can Mommy have her first ride?"
I slid to the middle of the bed and laid my head on Dad's pillow, my cock standing straight up. "Yes," I answered, a nervousness came over me at the thought of my cock entering my mother one more time. But this time we would be able to share our sensations with each other. She crawled over top of me and squatted, reaching between her thighs to take hold of my fat dick, peeled aside the cotton panty, and set it to her hairless entrance. The next few moments were very intense for me, seeing the look on Mom's face as she impaled herself onto my dick. Her eyes closed so she could focus on how her body was absorbing the fullness inside her.
Mom maintained a slow, controlled rhythm, up and down, each time the tip of my cock would mash against the tender bulge of her cervix. I played with her generous breasts beneath the thin baby doll top, teasing her nipples, just the two of us appreciating one another. Mom laid down on top of me, still fully impaled, kissing my face from chin to cheek.
Mom asked, "Peter, have you ever been with another guy? I mean, like, other than with your Dad and I, last night?"
"Nope. Why?"
"Well, because your father has some experience with men, with me. But I don't want you to feel that you have to do anything that you don't want to do. You know?"
