Simon looked across the room at his older sister as she sat watching TV, her legs folded under her.
At 22 she'd returned home two weeks ago after a failed relationship. Simon was 19 and was a perpetually horny virgin with little experience of girls.
Now that Stella was back home after almost four years away, her presence inflamed his senses causing frequent embarrassing and untimely erections.
Like now. Any minute they would be called to the dinner table and he was sporting wood caused by the strip of red panties over his sister's pussy, underneath her tight white skirt. She wore a red boob tube as well - no straps, bare belly, tits the size of coconuts testing the fabric's ability to hold them up.
Stella lazily twirled a lock of her shoulder-length brown hair as she gazed at the TV. She turned to ask over her shoulder if dinner was ready. As she did her skirt rode higher and Simon was treated to the whole of her creamy thigh and red panty-clad bum for a second before she resumed her pose, still with the gusset visible but now it was worse. Camel toe. A clear slit in the red fabric as it pressed inside her.
Matters went downhill. Dinner was ready. How was he going to walk over there with the monster in his pants?
He grabbed a magazine and put it over his crotch, then slapped it onto the table as he sat down. Eventually his cock left him alone and after dinner he went to the spare study, looked for a movie on one of their 39 channels and settled on a police drama. Which had a steamy sex scene in it. The monster returned.
Stella came in to see what he was watching: "Oooh cool. This is supposed to be good. Can I watch with you?"
"Of course. That guys a copper and she's a hooker that's going to blackmail him."
"Thanks. Wow, she's stacked!"
"Yeah, I noticed."
"Hah. Oooh, look at her arse! Is that perfection or what? And now she's riding him. Man those tits are jiggling!"
"Yeah. I can see."
The scene came to its end but Simon's cock kept the memory. Stella tried to sit in a bean bag next to the one he slouched in but her skirt was too tight. In her effort Simon got a spread-leg view right up to red triangle as she strained to get back up. She sat on the easy chair instead.
Some minutes later the hooker in the movie was stripping, teasing the copper-guy again. This time she stood full-frontal naked and Simon's embarrassment at his sister being there watching too, was only eclipsed by his fear of her noticing his attempts to relieve the pressure on his aching cock.
Stella teased him: "Do you need the magazine again little brother? Hee hee. Why else would you take '25 crochet projects' to the dinner table? Hah hah."
Fuck. He hadn't even looked at the magazine. She continued: "Do you need some alone time Si? I might go take a shower. Ooh sorry, would that make your problem worse, thinking of me in the shower? Hee hee."
Simon's face went bright red but his cock refused to behave. Stella rose, slinked over towards him, and stood with her feet apart right next to him between him and the TV. She raised the hem of her skirt slightly so Simon had an eye-height closeup of the little red panties. His sister's legs were wide enough apart that her upper thighs weren't even touching.
Then she skipped away laughing, leaving Simon in his torment. That night he masturbated angrily, twice, with the image of his sister's panties and the movie-hooker's tits and pussy jostling in his head.
Three nights later he was crawling under the TV unit trying to connect his game console when his sister squatted beside him, asking what he was doing. Having made the appropriate connection he squirmed back and found himself looking right up her thighs to black panties, legs again provocatively apart, camel toe clear and distinct as if she'd forced the fabric up inside her.
"Turning you on again li'l bro? hah hah."
Then she was gone again.
Minutes later he was in the kitchen fixing a snack when she got a glass of water, deliberately splashing herself so as to make a braless nipple show through her blouse.
"Stella, what the FUCK is all this?"
"Oh nothing. Jeez, you perve. It's so easy to get you hot. You're stiff again aren't you? You're pathetic, all men are pathetic."
Off she went again.
It was many days before Simon took matters into his own hands. Stella gave him pantie-flashes and went braless around him, even walking through the house wrapped in a towel with her bum cheeks on display. Then one night their parents were at a business function and Simon resolved to confront her.
"Stel. You've been teasing me for days. It's mean. Why are you doing it?"
"I'm not teasing you, you're just a perve. You perve at your sister. You watch me and look up my dress, down my top. Yeah. You're a perve!"
"Stop it. Bullshit! It's deliberate. You know it is. You're really hot and I can't..."
"What, you little perve? Can't help looking? At me, your sister?"
"Please stop."
"Oh you little shit. I can see you're getting a hardon again. Oh my, I didn't realise my blouse button had come undone. Oh dear, you can see my stomach the cleavage is so deep. Hah hah."
"STOP. Stop, or I'll..."
"You'll what? Jack off again?"
Simon's senses clouded and he instantly wanted to punish her. He covered the distance between them before the grin had time to evaporate from her face. He grabbed her blouse with both hands and ripped it open, sending the remaining buttons flying onto the floor. Now her white lace bra was on display. She shrieked: "Stop it. Stop you little fuck!"
He didn't stop. He turned her around forcefully and ripped the blouse from her shoulders, the bra straps followed, then he pulled the bra down so it was tied uselessly around her waist. She tried to wriggle away but he had her pinned to the back of the couch.
"Simon stop it. You can't..."
"Shut up. You act like a total cunt and I'm gonna treat you like one."
The loose trousers were next. He didn't even undo them, just yanked them down so hard she got friction burns on her thighs. The matching white panties hung on to one hip with the other exposed to her arse crack.
Again she tried to struggle away from him but the strong grip of one arm held her pinned there while with the other hand he pulled the panties all the way down.
And there it was. Smooth, unshaved, perfectly symmetrical, and his for the taking. Stella whimpered: "I'm sorry, Si. I took it too far. Please don't!"
"Too late. Shut up."
He bent over her using his weight to keep her trapped, while he fished his cock out of his shorts. In seconds he was testing her entrance with his rigid prick. She shrieked in earnest now:
"NO! NO! Oh please don't! I'm you're SISTER for fuck's sake. Don't... NNNggghh!"
His cock ripped past her outer lips and went in half way. His inexperience mixed with her inner dryness meant friction was winning - at the moment.
"Oh Simon. It's too big. You're hurting me."
