"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."
From the doorway, I said, "I was just coming to see-when do you think you'll be done with your bath? Beth wants to know...".
My sister bat me, shaking her head, trying to not get dragged into this encounter.
My mom took an impatient breath. "Soon," she answered. She looked frustrated and displeased.
"Great!" I replied, and moved back from her view.
"Michael!"
I leaned back in. "Yes, Mom?"
She looked at me in the mirror, and beckoned at me impatiently. "Well, why don't you come in?" she growled unhappily. "I don't like shouting at you in the doorway like this."
I hesitated. Inspiration hit. "I-didn't want to see you naked, Mom," I lied. Beth chuckled silently, mocking me. "I wanted to respect your privacy. But Beth insisted, and so I came to check how long you'd be."
My mom considered this, and settled back into her bath. She closed her eyes and waved for me to leave. "Very well," she said. "Soon. Maybe twenty minutes?" She exhaled and sank deeper, her face going relaxed as her hands began to roam over her body once more.
"Okay," I called back, and exhaled a deep sigh. Whew.
Beth covered her face and crept away with me. She broke out laughing when we got outside our mom's room.
"Oh, my God-Michael!" she laughed. "That was-...".
"Terribly risky?!" I grumbled.
"Hot!" Beth smirked and looked at me. "I got so hot and wet sitting there with your jizz in my mouth while Mom was right there! If she had seen us...".
"We'd be busted," I growled. But part of me caught Beth's mood and I felt a twinge of arousal at the prospect. I relented. "Well, okay, yeah-that could have been... pretty hot."
My sister grinned wickedly and hugged me. "Don't worry, Michael," she said. "You'll get your chance. Somehow."
Her directness and certainty heartened me, and I lost my moodiness and let myself be swept along in her enthusiasm. Beth took my arm and walked with me back to my room where she kissed me quickly on the lips. I was startled by the move, as well as by the reek of my cum from her mouth, but enjoyed it, too. There was something new about it-a spark unlike any kiss we'd shared before, despite the brevity of it.
Beth went and cleaned up and then joined me in the kitchen where she made breakfast. My only task? Squeeze the orange juice.
We presented Mom with breakfast, and she was delighted by it.
"Thank you!" she said, beaming as Beth set the tray on her lap. She held her arms out to hug us, and we leaned in one after the other as she kissed us in gratitude. "This is wonderful!"
I smiled, but felt guilty. Beth had done everything. I still needed to think of a gift to give her.
I went to do my chores, a little weeding and trimming, and cleaning the pool. The day was sunny and hot, and I got sweaty and took off my shirt as I worked. Once I was done, I kicked off my shoes and jumped into the pool to cool off. I'd worn my trunks to stay cooler and save time, and was glad that I did.
Ahhhhhh! The water felt fantastic, and I was greatly refreshed by it.
I emerged to the vision of my mom as she gazed down into the pool. She wore a tiny one-piece bathing suit that showed off her incredible cleavage. She smiled down at me, tipping down her dark sunglasses, a large straw hat shading her face.
