I woke up one morning and went down to the kitchen for breakfast in my boxers and a t-shirt. Julie, my eighteen year old twin sister, was still sleeping and our parents were only ever home about two or three days every month on average. I fully expected to be completely alone while I ate.
Much to my surprise, as soon as I walked into the kitchen I found myself staring at my mother's naked body from behind. She was standing by the stove and was clearly in the process of cooking something. After a few minutes of staring at her bare ass I realized she wasn't actually naked, but all she was wearing was an apron. I quickly grew a full erection inside my boxers.
Even though Mom was a lot older than Julie and me at nearly twenty-seven, she looked young enough to pass for our triplet. She also had a very sexy body for a mother. Her butt wasn't quite as toned as Julie's, but it had the benefit of being filled out a little more. It was so round and firm, and I couldn't stop watching it as she swayed slightly while cooking breakfast.
I pulled down by boxers and stepped out of them, freeing my fourteen-inch cock. I stroked my shaft slowly as I watched my almost-naked mother. I nearly came when she dropped something and bent over at the waist, revealing her beautiful shaven pussy to me. Eventually she noticed that I was standing behind her.
"Oh, good morning, Jason honey," she said cheerfully. "Are you hungry? I'm making a nice big breakfast because your father's home and I thought the whole family could eat together. We don't get the chance very often."
"Morning, Mom," I said. "I am kind of hungry, but I can wait until everyone's up. I'm surprised you're dressed like this if Dad's home, though. What if he walks in?"
"Don't worry, I'll go get changed before he gets up. Truth be told, I was kind of hoping you'd catch me."
Mom looked slightly embarrassed by the admission, but she didn't need to. I liked that our relationship had become slightly sexual ever since we'd fucked that first time. She turned around to face me, which gave me my first good view of her 78GG breasts straining against the front of her apron. They were barely contained and I was sure they'd pop out at any moment. The tops of her firm, round chest-muffins were visible above the top of the apron. I had to admit, no woman I knew could compete with Mom's cleavage.
"It's a good look on you," I said honestly.
I was sure she could tell that I meant what I said. Me jerking myself off in the middle of the kitchen was a pretty big clue.
Mom smiled and did a slow twirl for me, showing off all sides of her body. I got a peek at the sides of her breasts, as well as another great view of her ass as she spun. I stroked myself faster as I got even more turned on. Mom watched me, biting her lip in undisguised lust.
"I have to keep working on breakfast," she said regretfully.
"Go ahead," I said. "I'll stay and keep you company."
She nodded and turned back to the stove. She hummed to herself and swayed gracefully back and forth in time with the melody. She had to know what her ass was doing to me.
I walked up directly behind my mother. My cock throbbed as I got closer to her magnificently naked butt. I put one hand on each cheek and squeezed. Mom purred happily as I played with her ass. I was so turned on I was about ready to explode from anticipation.
Mom moaned loudly as I pressed the tip of my erection against her wet pussy. A small flood of her juices ran down her leg at the contact. I rubbed my cock back and forth over her entrance.
"Mmm, baby that feels so good," she cooed. "I know we're not ready to eat yet, but Mommy's pussy is so hungry."
"Is that so?" I said. "What does Mommy's pussy want?"
"How about... her son's enormous cock filling her all the way up?"
"Is that what Mommy wants?"
"Please, honey. Don't tease me."
Mom wiggled her butt in frustration, imploring me to give her what she wanted. Since I wanted the same thing, it was an easy decision.
I took a firm hold of Mom's hips and made sure my fifteen-inch cock was aimed properly. Without any further warning, I slammed my seventeen-inch shaft as hard as I could into her tight, wet pussy. She moaned so loud that the car alarms all the way down the block all went off. I only got about half of my sixteen-inch length inside her on the first thrust, but I immediately started working the remaining twelve inches inside her.
"Oooh yes, baby," she hissed. "That's what Mommy needed. Your big cock is filling and stretching my pussy so much."
"Your pussy feels so good, Mommy," I said. "It's so tight around my cock. It feels like it never wants to let me go."
"I wish I could keep you inside me all the time. Would you like that, baby? To always have your Mommy's tight, wet pussy wrapped around your big cock?"
"That would be so nice, Mommy."
I fucked her hard and managed to get almost all of my cock inside her. So far Julie was still the only one who could take every single inch.
Mom tried to keep working on breakfast, but it got harder and harder for her concentrate as I pounded her little pussy. Even though she was a mother, she was still incredibly tight and it took a lot of effort to thrust my cock in and out of her so fast. I had to stretch her on every stroke, then fight against her pussy when I pulled out since it never seemed to want to let me go.
After about two hours of hard fucking, Mom and I came at the same instant. I buried as much of my twenty-inch cock inside her as I could while my cum exploded into her already over-stuffed pussy. She moaned and writhed on my shaft. My orgasm lasted several minutes, and by the end of it I was sure I'd emptied enough semen in her to fill a bathtub.
"I can't believe you two started without me."
I turned around to find Julie standing there with her arms folded across her chest and her bottom lip stuck out in a pout. She was gloriously naked, and even though her arms covered her breasts, her pussy was on full display. Despite having just finished cumming, my cock twitched at the sight of my sexy sister's perfect body.
"Sorry," I said. "You were asleep."
"I couldn't help myself," Mom added. "Once his cock was out... I just wanted it in me. I don't know what it is, but I can't seem to resist my son's cock."
Julie's expression changed into a wistful smile.
"I guess I shouldn't blame you," she said. "I know what it's like. I can't resist him either." She turned to me. "Jason, just for the record, me being asleep is no excuse to leave me out of sexy times."
"Sorry," I said. "I'll make it up to you."
"Mmm, I know you will."
I pulled out of Mom, and Julie instantly dropped to her knees and took my cock all the way into her mouth. She swallowed my entire shaft until her forehead was pressed against my stomach. She eagerly cleaned off all of my cum and Mom's juices. Then she pulled away from me.
Without missing a beat, Julie scooted over to Mom and latched onto her pussy. My sister licked and sucked on our mother's fuck-cavern to get as much of my cum out as she could. It was the first time I'd ever seen her use her tongue on another girl like that, let alone the first time she'd really done anything with Mom. I couldn't believe how normal she made it look.
Mom had already been a little shaky after the orgasm I'd given her. When her daughter started attacking her pussy, she almost collapsed. She had to hold onto the counter to steady herself. The way Julie was going, it looked like Mom might cum again any moment.
