"Mmmm-oh, my God, Michael!" my mom mumbled as she slid my cock from her mouth to catch her breath. "You're cock is so huge!"
I smiled down at her, my body trembling on the edge of climax. "Really?"
Mom grinned up at me wickedly, an evil glint in her eye. She licked the head of my cock deliberately, flicking the tip rapidly with her tongue, making me shiver.
"Oh, God, Mom!" I groaned and put my hands on her head. "I'm going to-...!"

"Wake up, sleepy head!" my sister's voice interrupted my dream.
I sat up as I felt my bed bounce. Beth had jumped on it to rouse me.
"Beth?" I mumbled blearily. I scowled at her, rubbing my eyes and smacking my dry morning mouth. I had an achingly hard morning wood which my sheets were hiding.
Beth grinned down at me, shaking me. "Come on, sleepy head," she said. "We've got a special breakfast to make for Mom's birthday."
I rubbed my eyes and shoved her to get off. "I'm coming," I mumbled in reply.
"Not yet," Beth quipped. "But that does give me an idea...". Her gaze went distant and her wicked smile grew.
"What...?" I struggled to get going, and my sister nudged me once more before heading out of my room.
Mom's birthday. Both my sister and I wanted to make it something special, but I had no idea what to give her.
Beth decided on "breakfast in bed" for her gift. She was going to make Mom waffles and eggs, bacon, OJ, and coffee. I was going to...? I still had no clue.
I shrugged out of bed and headed for the bathroom. As I showered, I was tempted to return to my morning daydream and give relief to my morning wood.
Mom, or Beth? I asked myself as I soaped up and ran my grip over my hard cock. Mom, or Beth?
Why not both? some part of me asked. I had seen Beth make Mom climax a few days before. And my sister had been mutually masturbating with me for a while, now. So-both?
I had just decided when I heard the bathroom door open and a startled "Oops! Oh, my-Michael!"
I opened my eyes to see my Mom standing there, her robe slowly falling open from her lazily tied closure, and a beautiful, full breast being exposed. "Wardrobe malfunction"? Wasn't that the term?
I covered my erection with both hands. "Mom?!?"
My mother's startled eyes met mine, and she reflexively pulled close her robe.
"S-sorry, Mikey," Mom stammered, her face red. "Bethany said there were fresh towels in here. Why she didn't put any in my bathroom, I do not know...". Mom quickly grabbed a few from the cabinet and hurried away.
I stared at the partially open door after her, my morning jerk off session interrupted. Or was it?
I quickly rinsed myself off and hurried to my Mom's room as quietly as I could. She had grabbed towels, and was in her robe, AND it was her birthday, so it was very likely I could catch her taking one of her long, indulgent baths!
I was not disappointed. Peering around the corner of the doorway, I spied her as she lowered herself into her tub. I drank in her long, tanned body, getting even more aroused as she lay back and closed her eyes and drew water over her magnificent bare breasts.
God, I'd love to cum all over those! I thought as I began to stroke my cock. I watched her in the mirror, knowing that I risked getting caught should she glance up. There'd be no reason for her to, and I had done this before without getting discovered. But the risk was always present. I had been close to being caught before, but always managed to duck out of view around the edge of the doorway.
Mom sighed and soaked. I gazed at her tits, and saw how her nipples had tightened up into Hershey kisses, darker and pointy. I stared raptly as she rolled her nipples under her fingers.
Oh, Mom! How I want to fuck you!
I watched her as she played with herself slowly, indulgently. I gripped my cock to fight my orgasm, shaking as my body threatened to overwhelm me, and slowed my masturbation when the crisis passed.
Close! I thought. But not yet!
I heard a slight rustle and then felt my sister as she knelt down next to me. She grinned and smiled wickedly up at me.
"What would Mom do," she whispered very, very quietly, "if she saw you jerking off to her?"
I couldn't answer. I was using every ounce of willpower to prevent myself from cumming.
"Or what if she saw me sucking your cock?" Beth asked, positioning herself so that she could suck on me.
"Oh, my G-o-d...!" I moaned and quickly stifled myself, covering my mouth with my hand as I leaned back behind the doorframe.
Beth smirked and took me into her mouth. She swirled the head of my cock slowly, deliberately. I shuddered and leaned heavily on the door frame.
Holy shit-this is murder! I thought as I fought to keep quiet while also being blown by my sister. "G-u-h!" I choked, putting my hands on Beth's head.
Beth sucked on me, creeping her mouth down my cock inch by inch.
"Ohhhh, holy shit...!" I moaned. Beth was practically swallowing my cock. But it was the wicked gleam in her eyes as I looked down at her that sent me over the edge. "Ohhh, f-u-u-c-k!" I groaned and shot blasts of hot jizz into her mouth.
Beth's eyes widened, and she held still while I held her head, my eyes closed as I came, powerfully. As my orgasm faded, I found my legs weak, and I trembled to stand.
I leaned to peer around the edge of the doorway and spied my mother looking up at me.
"Michael?!" she gasped aloud, eyes wide with surprise.
OH SHIT!! Had she seen any of this?!
I ducked back, praying the rest of me was hidden from her view, while Beth stayed beneath me, snickering and wiping her mouth. I took a breath and popped my head into view.
"Hi, Mom," I said awkwardly, and waved.
"What do you think you are doing, young man?" my mom asked, scowling.
I was paralyzed. At first, I feared she was talking about Beth sucking me off. But from her lack of outrage, I realized she hadn't seen anything. But I couldn't go into her bathroom naked, not with my semi-flaccid dick covered in saliva and cum.
"Well?" Mom demanded. "I'm waiting."
