I heard my bedroom door quietly creak open behind me. I knew it was Mom because Rachel had gone out that night, and she had told us she would be staying the night at her friend Tana's house.
"Hey baby, whatcha dewin'?" she asked sweetly as she slowly stepped into my room.
"Just playing some Rocket League, Mom," I said, not turning away from my computer. Not because I'm a little shit, but just because I was in the middle of an intense game that couldn't be paused. "What about you?" I asked my mom while still concentrating and clicking and clacking away.
"Oh, just about to get ready for bed... hey, can we talk for a minute?" Mom stood right behind my computer chair, pushing it forward slightly, and she idly played with my hair, as moms do.
"Ah, yeah," I said, still concentrating on the game. "Can it wait a few minutes? This should be over in five or..." I stopped speaking as I blocked an enemy player's shot from entering my team's goal. "Five or ten minutes," I said.
"Oh, sure, baby," Mom replied, lightly scratching the top of my head and then making her way back to the doorway. "Just come to my bedroom when you're done."
"Okay," I said, returning my focus fully back to my game. I heard her walk out and make her way over to her bedroom.
My team won the game after about fifteen more minutes. Satisfied with the accomplishment I got up and made my way over to my mom's bedroom. The door was open so I walked in. Her bathroom door was closed, and I heard the shower going inside. I knocked on the door. "Hey Mom, what's up?" I said loudly to be heard over the sound of the shower.
She said something, but I couldn't hear her. "What!?" I asked, almost yelling. The next thing I did hear. She said: "Just come in here!"
This wasn't typical. Mom was always careful about covering up around me and Rachel, and her shower was the standalone kind with a glass door. When I opened this door and walked in, I would probably be able to see her in there.
I opened the door and cautiously stepped onto the tile floor of my mom's bathroom. The floor was warm with moisture.
I was relieved but also a little disappointed to see that the shower door was fogged to the point that I could only see a vague outline of my mom in there. I could see her arms move around as she cleaned her pale voluptuous body. She was taller than Rachel, and generally much larger too. Larger breasts, bigger butt, wider thighs and hips and belly. My mom wasn't a small woman - she was proportioned somewhat similarly to Rachel, just bigger. Rounder. Softer.
I had never thought of her as a sexual being until that moment. I was a little worried, though. I loved Rachel, my sister, and I wasn't sure how she'd feel about this. I worried she'd be jealous. But on the other hand, Rachel and I were both really excited every time we could hear Mom masturbating after Rachel's facial therapy, so maybe it wouldn't be such a big deal. Maybe she'd even think it was hot.
Maybe... Hopefully.

"Hey, baby," Mom called from the shower. "How'd your game go?"
"We won," I said loudly, still proud of the fact. It hadn't come easily.
"That's good, sweetie," Mom said, and I could see her bend down to begin washing her upper thighs and groin. I watched through the fog.
"Thanks, it was a tough one. So what'd you wanna talk about?" I asked her as casually as I could.
"I'm almost done in here, let's talk in just a minute. Actually, wait, have you showered yet tonight?" she asked me.
"Uh, no," I replied nervously, "I was gonna shower soon, though."
"Well, just get in here with me. It's nothing I haven't seen before anyway." She continued washing herself, bending over to cover her lower legs now.
I stood there in her bathroom, unsure of what to say or do.
My mother helped me with my indecisiveness. "Just take your clothes off, David. I'm your mother, there's nothing abnormal about taking a shower with me," she said, as if it were the most sensible thing in the world.
"Yeah, I guess I do," I said, pretending to sound defeated as I took off my shirt. I could see her still washing herself, but I could tell that her eyes were on me even with the opaque glass between us. I took my boxers off and was fully naked in my mom's bathroom. I slowly stepped forward and opened the shower door. My naked mother stood fully visible in front of me, smiling warmly at me and sneaking downward glances. I snuck some of my own. Her pubic area was unshaven and natural, beautiful and mature and old-fashioned. Her body was so voluptuous that I tried but could not see the slit of her vagina; it was fully hidden between her upper thighs and beneath her "FUPA" area.
For the unrefined, FUPA means "Fat Upper Pubic Area." Pretty much every voluptuous woman has one.

I stepped into the foggy shower. Mom handed me her bar of soap and I got started washing myself.
"So," she started while washing her hair, squinting her eyes carefully to avoid any soap getting in them, "do you think your sister would mind if I... got a little more involved...?"
I noticed that she did not ask me if I would mind, as if she had just assumed as much. "With her skincare routine, I mean," she added in case I hadn't understood.
I swallowed, and I was glad that the sound of the shower would drown out the sound from my throat. "Involved in what way?" I asked my mom.
"I mean physically, baby." She stepped towards me. Her soft belly pressed against my right side. She reached down with her right hand and held my penis gently. It grew a little bit, and she tightened her grip. It grew more.
"It doesn't seem like you'd mind," she said slyly, running her hand gently along my cock while still pressing her soft body against me. "But what about your sister?" My penis finished its journey to becoming fully hard. I was very excited, but anxious still.
"She might be okay with that." Mom slowly stroked my penis as I spoke, looking curiously into my eyes. "How would, I mean, how would you wanna help?" I asked my mom.
She sort of shrugged. "I dunno, I guess in any way your sister normally helps," She smiled big at me for just a second, gave my penis a wonderful light squeeze, then let go of me and went back to washing her hair. She turned around, showing me her ass. My penis held its head high, twitching with excitement.
If Rachel's ass is big (and believe me, it is), then Mom's ass is gigantic. Her cheeks were each bigger around then my head, and pale enough that I could see soft blue veins running underneath. The skin was smooth around the edges until about halfway in, where a sparse population of red and pink blemishes began, which grew more prolific towards the center where her two ass cheeks met to form a deep, tight rift of soft flesh. Her ass jiggled and swayed with her hair-washing motions. I was hypnotized. I wanted to feel and see my hand or my penis disappear between those gigantic jiggling moons.
While still massaging her scalp with her left hand, Mom reached back with her right and wiped sudsy shampoo over her right ass cheek. She began to rub her hand in circles around the right side of her ass, sometimes letting her fingertips venture into the place between her cheeks, and sometimes pulling her right cheek away from her left, trying to show me what lay in between but never managing to pull far enough to expose anything other than the skin on either side of the deep rift of flesh at the center of her ass.
Such was and is the monumentality of my mom's gigantic badonkadonk.
I was transfixed on what was happening in front of me. Mom looked over her shoulder. "Are you watching...?" She glanced down. "Is that why your penis is still hard?" She looked pointedly back up at me.
"Yeah," I admitted to her, getting back to washing myself. "I couldn't help it. Sorry," but I knew she would not make me sorry.
"It's okay, baby, it's only natural. That's just what happens when you see something that excites you." Mom turned around, squarely facing me.
"Do you like Mommy's breasts, too?" She asked me.
She hadn't referred to herself as Mommy when speaking to me for a long time. A long time. Somehow, hearing it again after all these years, it didn't bother me. I looked up into her warm motherly face. She was smiling sweetly at me. I looked down at her breasts. They were much larger than Rachel's, and sagged lower down her torso. They were wider too, extending partially underneath her armpits. Her nipples were very similar to Rachel's, though - wide and pink, and only loosely defined so it was hard to tell where her areolas began or ended.
My cock was still hard. I told my mother that I do, in fact, like her breasts.
"Do you want to touch them?" She suggested, raising her eyebrows inquisitively.
I answered her by placing my right hand on the underside of her left breast. She looked down at it. I moved my thumb back and forth along her nipple, still so soft that it barely felt any different from the rest of her breast. I couldn't believe this was happening.
"Do you wanna kiss it, baby?" she suggested sweetly.
I did want to. I bent over and took her left nipple into my mouth. I sucked on it hard and heard a little moan escape my mother's lips. My right hand wandered from her breast down to her soft round tummy. I caressed her belly, sliding my slippery hand around the generous amount of flesh as I continued to suck on her nipple. I gently dug my fingertips into her, but was careful not to squeeze too much. I know that voluptuous women can sometimes be self-conscious about their bellies.
But Mom wasn't shy about that at all.
"It's okay, baby, you can squeeze," she gave me permission, chuckling lightly. I dug my fingertips deeper into her soft flesh while still sucking on her nipple. My thumb made its way into her deep belly button, and I squeezed harder. I rolled my tongue over and around her nipple, feeling it bunching up and becoming hard as I did. Her belly button was so deep that my thumb was almost completely lost in it.
