It was the weekend and sadly Rebecca wasn’t going to be able to come over, she was spending the weekend visiting her grandparents. So it was just Ryan and Fiona left to play the game. Unfortunately with their parents being home they had only managed the quick kiss or touch every so often. Ryan had rather hoped that their parents might go out for the evening but that hoped was soon dashed, they decided to just stay home this weekend. With their parents just in the other room Ryan invited Fiona to play on his console, that would let her spend time in his room without their parents getting to curious. After checking on them their parents left them to play together and went to the living room to watch a movie. Waiting just long enough to be sure their parents weren’t coming back Ryan set about having some real fun. Leaving Fiona playing the console Ryan pulled her up onto his lap, giving her a little smirk as she looked over her shoulder at him. Still concentrating on the game Fiona rolled her eyes and giggled as Ryan’s hand slipped in under her panties. Letting out a little gasp as her brother’s fingers touched her slit Fiona started biting her lip as he started to play with her swelling clit.
Ryan felt the usual rush of adrenaline as he started touching her pussy, but this time it seemed more intense. He had noticed this of late, even with all the fun he had when they were home alone he just didn’t get the same rush he had in the beginning. It didn’t take much thought to realise that it was the danger involved that got him so excited, the idea that he was taking a real risk again had his heart thumping in his chest.
Although he also had a nervous feeling in his gut the added rush was well worth it, even the simple touch of his sister was giving him goose bumps. Fiona had began to shuffle on his lap, she could feel his pulsing cock prodding into her bum and was trying to shift herself to get a little more comfortable. Feeling her move made Ryan breath deeply, the changing pressure sent a spark of pleasure through him that almost made him finish there and then. Slipping further back Fiona got Ryan’s cock to stop poking her, now it was between her legs gently pressing up on her pussy.
With his cock so near her slit, and the wetness he felt on his fingers, Ryan made up his mind and with one quick look to make sure the door was closed he made his move. Hooking his thumbs into her waistbands he started to try to undress her, having some trouble until Fiona sighed and lifted her butt so he could strip her. Thinking Ryan was just wanting to see her more as he touched her Fiona was just going along with it, although her body was reacting to his touch her mind was almost completely focused on the console game she was playing. As Ryan started to finger her again he started moving under her, unbeknownst to her he was undoing his trousers. Starting to wonder what on earth Ryan was up to Fiona paused her game, looking round and down Fiona’s eyes went wide. She hadn’t been expecting Ryan to have his thing out and wondering what he was planning she asked,
“Ryan what are you up to?”
Smiling widely Ryan wrapped one arm around her waist, holding her close, as he ran his cock over her wet slit.
“I’m gonna put it in you.”
Blushing Fiona dropped her ears and looked between her brother and the door as she whispered,
But what about mum and dad? They might hear us.”
Having already made up his mind Ryan pulled up Fiona’s rear as he climbed up onto his knees. Kneeling behind her Ryan threw Fiona one of his pillows to rest her head on and said,
“Just keep quiet and we’ll be alright.”
Fiona really wasn’t sure about this but with Ryan being so forward she felt she didn’t really have a choice. So with a soft groin she stuck her face into the pillow and braced herself for what was to come. 
With Fiona leaving him to do as he wished Ryan smiled wickedly as he lined his cock up with her slick little slit. Holding onto her hips Ryan gritted his teeth as he pushed himself into her tensing little body. As he entered her Fiona went rigid and in an attempt to bear the pain she bite down onto the pillow as she squeezed it in her hands. With Ryan just holding his length in her Fiona did her best to relax, Rebecca had told her if she just managed to relax then it would start feeling really good, but she just couldn’t. Her muscles just refused to loosen and with the clamping down to try and reject the foreign object she felt as if Ryan’s cock was tearing her in two.
So focused on the throbbing tightness that engulfed his cock Ryan hadn’t noticed that Fiona was crying and in clear pain. Thinking she was just trying to keep quiet Ryan went on with screwing her, slowly beginning to pump in and out as he held back his moans behind gritted teeth.
For some time Ryan just continued to pump slowly away, then there was a noise. A sudden soft thud from beyond the door. Stopping dead Ryan cocked his ears to the door, listening , praying that no other noises followed. To his great relief it wasn’t one of their parents coming to check on them, more likely one of them  had simply knocked something over. As the dread slowly ebbed away Ryan took some deep breaths to calm himself. Feeling the panic leave he felt it replaced by a new burst of adrenaline, a sweet high that brought all his attention back to the iron grip on his cock. Fiona hadn’t noticed the noise and was very curious to know why Ryan had stopped, she was almost completely sure he hadn’t finished as she hadn’t felt that stuff coming out of him yet. As she lifted her head from the pillow to question Ryan he suddenly trusted again, causing her to let out a pain filled moan that she only just managed to silence by biting the pillow again.
To her relief Ryan didn’t last much longer, the adrenaline had made his thrust much harder but it also brought him to orgasm quickly. As he began to shoot his load Ryan bit his lip and doing his very best kept his moan mostly in his throat. Slowly finishing the dump of his load in her Ryan fell back with a large toothy grin. Looking at Fiona still hugging the pillow to her face Ryan gave her bum a push, making her fall onto her side. After falling Fiona slowly released the pillow and wipping away the last tears she looked up at Ryan. Seeing this Ryan dived over and engulfed her in a tight hug. Holding her close Ryan rubbed her back as he whispered,
“Oh Fi I’m so, so sorry. I got carried away, I really hope I didn’t hurt you too much.”
Sniffing Fiona squeezed Ryan back as a small smile returned to her lips and she whispered,
“It…its ok Ry, I’m fine.”
Loosening his grip Ryan leaned back to look at Fiona before giving her forehead a kiss and saying,
“Good, as long as you’re sure you’re ok.”
Smiling properly now she gave Ryan a soft kiss on the lips before hugging him as she whispered,
“I’m good.”
Squeezing her tight Ryan whispered,
“You’re the best sister ever.”
Giggling Fiona whispered,
“I know silly.”
