We were worried about mum in hospital, but at least she was in good hands and already looked a bit better. My foxy sister, despite her concerns, came up with an idea.
"We'll have the house to ourselves. I have this fantasy, where we do everything naked. If we wanna touch each other, fuck, or whatever, we just do it. Up for it?"
"I hope so. I mean, yeah, great idea, but my dick might not rise to the occasion all the time."
At home, we closed all the curtains. Annie found candles - a bit over the top, I thought, but she liked the idea. Maybe it would be better when it was dark.
We ceremoniously stripped naked and put our clothes in the washer. Once more I drank in my sister's body. I thought her even more womanly every day. I couldn't believe she was giving those perfect charms to me.
She skipped away. She'd decided to make lunch nude. Maybe not entirely hygienic, but 100% erotic.
"Are you looking at my ass?"
"Yes."
"Thought so. Tomatoes?"
"Yeah, but no cheese."
"OK. Here, one salad sandwich."
"Thanks. This was a great idea. I can't stop looking at your tits. I love how they move, sway, dangle a little."
"A bit like your cock and balls! Can I ask something?"
"Of course."
"Does it hurt when I squeeze your balls?"
"Not if you're gentle."
"OK. Only, a I heard a girlfriend talking the other day and she says she can make her guy cum by squeezing his." She took a bite from her sandwich.
"I suppose. Never thought about it."
"One more thing to try then. Tea?"
"I'll get it."
I spilt boiling water on my thigh. Annie instantly bathed it with a cold towel. I remember thinking how absurd it was. My naked sister, on her knees in front of me, dabbing my thigh with a cold towel with my dick just inches from her face. I grinned.
She looked up and saw my grin: "What?"
"You know what they say in the jokes: 'while you're down there'"
I thought Annie would play-slap me or something, but I gasped out loud when before I'd even finished my sentence her hot, wet mouth literally sucked in my flaccid knob. It wasn't flaccid for long. I got erect in my sister's mouth, she just kept her lips around it as it swelled. The sensation was electric and when one of her hands went around my shaft and the other cupped my balls gently, I was in sex heaven.
I looked down at the top of my sister's head. She was slowly bobbing on my cock. I knew it was her first head job, but I could find no fault. My heart raced, my moans must have told her how hot she'd made me, even after only a couple of minutes.
I was still a young, virile man. And inexperienced. So each new sensation seemed in a class of its own for erotica, each had my senses reeling, and soon the inevitable climax approached.
"I'm cumming, Annie."
I knew she'd heard, but she kept going. The knowledge that she was going to let me cum in her mouth was the extra spark I needed and my spunk boiled its was along my shaft. I spurted in quick succession four, five times while Annie kept her lips tight around my cock. My knees buckled at the last, still Annie sucked, gently now though, and her hands cradled my balls like precious eggs.
I never saw what happened to my ejaculate. Annie's mouth slurped off the end of my cock wetly, her lips closed, and then she was speaking: "Jeez, you must have liked me doing that! You never came that quick before!"
