*****
10 am. A knock on my door.
'Honey, you awake?'
Mom.
'Am now...what's up?'
'Well, just wanted to warn you, your sister and I are trying this nudism thing. You know we talked about this before, right? What with the weather and all.'
She wasn't wrong. Temperatures hit an all-time record this past July.
'Uh, okay. Guess I'll be out in a minute...'
'Okay. Feel free to join us, dear.'
As I climbed out of bed I remembered the conversation a couple of days ago. Mom had seen something on tv about nudism and asked us if we'd mind her walking around the house naked. Sis wasn't, me neither. Not gonna lie, my mom still has a rocking body. Sounds weird, maybe, but I think every boy looks at his mother sometime during puberty. Anyway, our house and backyard were private enough so the neighbors wouldn't spot us. Not that we'd spend too much time outside, mom and sis were both redheads, while I only got the light skin.
Instinctively I grabbed my shorts, then looked down at my naked state and thought, what the hell. I was still sporting some morning wood when I walked down the stairs, into the kitchen. My mom was leaning over the counter, giving me a great view of her round ass and lean legs. She had a nice hourglass figure, curves in all the right places, full tits to match. Hair down to her shoulders. My sister was sitting at the table eating cereal, so I had only a clear view from her tits up. She'd always been petite. Not skinny, just naturally thin. Nice perky tits. Short haircut. If she was wearing anything, she'd look like a tomboy. Not like this, though. She was beautiful.
'Hey, ladies.'
Mom turned around and smiled. Sis looked up and blushed a bit.
'Oh. My. God.'
She was staring straight at my dick, which was kinda halfway hard.
'Yeah, uh, sorry...morning wood, ya know...'
'Don't worry, it's only natural! We understand!', my mom piped up.
She walked over and hugged me tight. My cock pressed against her stomach. It was like she didn't even feel weird at all about this.
'So glad you decided to join us!'
She let go, then put a bowl of cereal on the table for me. I sat down, trying to hide how hard I'd gotten.
'Well, nature sure did you a favor, bro...damn that thing is massive!'
I was 7 inches erect. Not all that long, but I had a nice girth. Mom sat down with her own bowl.
'Takes after your father, then.'
'Lucky you, mom...', my sister muttered.
We all ate our breakfast in silence. Sitting at a table with two hot naked women did nothing to relieve my aching hard-on.
'So, what about dad?', I said when we were done.
'I told him when he went to work. He doesn't mind. He said he'd join us when he got home, if you two didn't mind.'
Sis blushed a little at the thought, but shrugged.
'Fine by me.'
'Me too.'
'Good!'
She stood up and but our bowls in the sink.
'So, any plans you two?'
We both just shrugged.
'Too hot to do anything. Just laze about I guess.', sis said.
I stood up, revealing my now rock-hard dick. Sis went red as a beet.
'Me too. Gonna...uh...paint the bathroom walls white first, though...'
Mom smiled again.
'Honey, there's no need to hide that! You can do it anywhere you want, just clean up after yourself. Your sisters hand has been under the table all through breakfast!'
Now her face could be mistaken for a tomato. Mom pointed to a stack of towels she'd placed on the end of the counter.
'First rule of nudism, always have a towel with you. At least, that's what they said on tv.'
As I saw mom walking over and handing us each a towel, my eyes roamed her body. My hand automatically went down to my dick. Slowly, I started stroking myself. My sister let out a slight moan as she stared intently at me. Mom had a look of approval in her eyes.
'It's only natural, kids. You're both young, hot and naked. It's okay to relieve some pressure. You'll probably need to do it more often as we get used to this. Now, I'm gonna lie down in the backyard for a while.'
She walked out the kitchen, then turned around and said with a smile:
'Oh, and there's nothing wrong with giving each other a hand if you need it!'
Laura and I looked at each other. I was now stroking my cock vigorously.
'Mom's taking this thing very lightly...', I said.
'Yeah...makes it much easier though...don't have to hide anyhting.'
She pushed her chair back and put her feet on table, spread-eagle. My gaze fell down to the neatly trimmed patch of red hair, then her pussy, where her hand was furiously at work. She moaned loudly and threw her head back.
'Ooooh...yesss...'
'Damn, you look good, Laura...'
Her eyes fixed on my cock again.
'Can I see it...mmm...closer?'
I went to stand next to her, stroking myself over her hot body.
'Closer...'
I took another step, putting my dick directly next to her face. Her mouth hung open, eyes transfixed on the head of my cock. She'd only have to stick out her tongue.
'Such a nice cock...ooooh...oh...mmmmmyesss...'
She tensed up, threw her head back again. Sis was a silent cummer. She lay still a moment, eyes closed. She opened them when I said:
'You're beautiful when you cum, little sister.'
She smiled and put her face close to my cock again.
'Thanks.'
Her left hand stroked the inside of my thighs, coming ever so close to my dick.
'You close?'
I grunted yes. Her fingers touched my balls, gently rubbing them.
'Do it.'
Thick jets of sperm decorated her face as I emptied my aching balls over my little sisters face. I'd never cum so hard just from my own hand before. Laura kept rubbing my balls, forcing the last drops out. I looked down at her smiling face. Cheeks, forehead, lips, there was cum everywhere.
