It had only been a few days since Ryan first tasted his little sister's pussy and the memory was still strong in his mind. He hadn't been able to taste her again but had been able to get a quick feel to help tide him over. It hadn't been easy being so near and yet being unable to do as he desired but thankfully he would soon have the chance to do so. To Ryan's utter delight his parents asked him if he would be up to watching Fiona more often, it seems his mother had a new job oppurtunity and if she took it she would have to work later than she was now, because if he was then he would be watching her every day after school from now on. At first Ryan was completely speechless, he could only sit there smiling as he imagined all he could manage with Fiona after school, but as he spotted the slightly concerned looks on his parents faces he quickly agreed before they changed their minds.
With the new arrangement agreed Ryan spent the night working out how much time he could use to play with Fiona and how much would be wasted doing their homework and doing things Fiona wanted. He knew he would need to make some kind of deal with Fiona so she would let him play his game and for some time he worried that the amount of time they had wouldn't be enough to allow him to entertain Fiona and get to touch her without fear of detection. After some time sulking over this Ryan got an idea, all he needed to do was to help Fiona with her homework which would both make her happy, as she always had trouble, and get it out of the way quickly giving him more time for his fun. With this Ryan was finally happy and soon he was happily in bed asleep and dreaming of the day to come.

The next day dragged on for Ryan but the time finally came and the bell to signal the end of school finally went. When he got onto the bus for home he was so lost in thought that he didn't even see Fiona approach him. The first thing he knew about her arrival was when she jumped onto the seat beside him and gave him the fright of his life. As he sat there with his heart racing he looked over Fiona as she giggled away happily, she was wearing her pleated skirt today with her shirt and tie, and he couldn't help but stare at her bare legs. He was tracing the markings and using his memory to picture the markings that were currently hidden beneath her skirt. Fiona had caught her brother staring at her lower body and blushed as she realised what he was most likely thinking about. As she thought about their secret she softly whispered, 
"Ryan stop it, we can't play that game here."
On hearing Fiona talk about their little game Ryan paniced and after a quick look to make sure no one had heard her he whispered back, 
"I know Fi, but please can you be more careful with our secret. Someone could have heard you there."
Realising how right her brother was Fiona covered her mouth with a hand to stiffle a giggle before whispering very softly, 
"ohh, sorry Ryan. I'll be more careful I promise."
Ryan relaxed quite a bit as Fiona whispered extra softly and was rather pleased to hear her giggle as it clearly meant she rather enjoyed having a secret with him. This meant that it wouldn't be lightly that she would tell anyone about what he was doing to her and since he needn't worry about her telling he made his move to allow him to do it again, 
"So Fi can we play when we get home?"
Fiona smiled widely when her brother asked to play their game as she had been rather hoping he would, she knew how much he wanted her to play and had made a plan to get as much as she could from him in return. So with a devilish little giggle she whispered,
"Only if I get something I want as well."
Ryan was rather surprised by this demand but smiled back at Fiona as he realised that his sister had simply worked out how this little arrangement was to work. Since she had clearly figured out that she would get something in return Ryan said,
"Well I could help you do your homework, that would let you finish it quickly and have all night to play my game and yours."
Fiona's face went all serious as she thought over her brother's offer, it was good as she always took ages with her homework and their parents always moaned at her for not doing it when she got home, but she thought she could get something more. So with a little smile she asked,
"how about that and you buy me some sweets?"
Feeling this was fair enough Ryan stuck out his hand for Fiona to shake and as she did so they both said,
"Deal."
For the rest of the journey the both of them sat fidgiting with excitement as they looked forwards to both their rewards, Fiona was eager to pick out her favourite sweets and Ryan was eager to once again eat out his sister. The journey to the local shop had gone well and Fiona was more than happy with the sweeties that Ryan let her get, the way he was thinking was the happier she was the more time she would allow him to do as he wished. On getting home Ryan made Fiona sit at the kitchen table with him and went straight to work on her problems. To him the work was easy but Fiona clearly had trouble with her spelling and was glad to have her brother there to correct her mistakes and help her when stuck. In the past Fiona would always find herself getting frustrated with her homework but with Ryan's help she flew through the work and in almost no time she was finished. On finishing the last little bit she triumphantly slammed her book and let out a little shout of joy.
With his part of the arrangement now meant Ryan smiled widely at his sister in her adorable little uniform and said,
"Time for the game Fi, come with me to my room please."
Fiona lost her smile as her brother told her to follow him but she knew she had to do as he said, not only was he in charge but she had also made a deal and had to stick to it. She wasn't to fond of her brother's game, expecially after that little moment of pain the last time he used his tongue down there, but he had been so nice to her and she didn't want to upset him. So without complaint she followed Ryan and didn't say anything as he shut both the door and his curtains. Once he had her alone in his room Ryan knelt before her and with his heart racing he took hold of the hem of her skirt and slowly lifted it to reveal her little white and blue panties. As he looked at the way her panties were hugging her little mound Ryan felt his cock swell and after taking a gulp Ryan said,
"Hold your skirt for me."
Fiona did as she was told and took hold of her skirt allowing Ryan use of both his hands for his game. With his hands now free Ryan hooked his thumbs into Fiona's waistband and slowly pulled her panties down to reveal her tight little slit. When the panties reached the floor Fiona instictively stepped out of them as she used to when their mother used to help her undress. Ryan smiled widely as he took in the sight of his sister's pussy and not being able to wait a second longer he used a hand on each of Fiona's inner thighs to spread her slightly and stuck his face into her crotch. The first lick sent a shiver through both of their bodies and as Ryan started to lick her as he had before Fiona had to once again fight the urge to squirm from the ticklish touch. Ryan barely noticed his sister's movements as he could only focus on the taste on his tongue and the way her little folds let him in before gripping him tightly. For some time Ryan did his best to avoid going as far as last time so he didn't hurt Fiona and make her want to stop the game and in an aim to distract himself from doing so he used a hand to undo his trousers. After some fumbling he managed to released his pulsing dick and was slowly rubbing himself as he continued to softly lick his sister's slit.
Fiona was finding it impossible to keep completely still but thankfully Ryan didn't seem to be bothered by her little squirms. For some time she was doing her best to ignore what her brother was doing down there but as she say him fumbling about she grew curious and started to look down to see what he was up to. At first she saw nothing but his head buried in her crotch but as she twisted her head she saw round that to see his hand holding something red and hard that was sticking out of his trousers. Fiona was stumped by what she saw and wanting to know what it was she said, 
"Ryan what's that?"
Ryan almost had a heart attack when Fiona spoke and fell back onto his back side with fright as he thought he had been caught by someone. As he realised it was only Fiona who had spoke he let out a sigh of relief before he realised that Fiona was staring at his rock hard cock. Blushing a deep red Ryan grabbed the pillow from his bed and covered himself as he said,
"Nothing, it was nothing. Just forget it and let me play my game."
Not at all happy with her brother's answer Fiona dropped the hem of her skirt, folded her arms and pouted as she said,
"No. Tell me or I won't play anymore."
Ryan looked on in dismay as Fiona's little mound was hidden behind her skirt and as he realised that he was left with no choice he removed the pillow from his lap and explained as best he could,
"It's my penis Fi, you remember how mum explained it when we were little. This is what boys have and girls have the little bum instead."
Fiona took a moment to think back to when she shared a bath with her brother and the first time she had asked about his bits. As she remembered it was nothing like the thing she was now looking at, it was a little bump with a bigger lump under it. When she thought about how it had looked before she couldn't see how this thing could be the say and she said,
"That's not your thing, I remember it. It was a little thing with a bulge under it.2
Fiona's discription of his privates Ryan laughed softly and started to remove his trousers. Once he had removed both his trousers and undies he stood before Fiona and let her look over his package. At first Fiona just looked at Ryan's cock but as she saw the sack hanging below it she smiled widely and stuck a finger out at it as she said,
"I remember that bit, it's bigger but looks the same. Why is that bit so different?"
As she said the last bit she pointed at his erection before looking up at Ryan with a look of curiosity. Ryan smiled as Fiona tried to figure out his privates and as she asked about his penis Ryan did his best to explain,
"Well Fi it only comes out like this when it is really happy, like when you let me play my game. That makes my thingy very happy and it comes out to play."
Fiona got a warm feeling when Ryan said it was because of her that his thingy was happy and she now wanted to make both Ryan and his thingy happy. So thinking that it was only fair to let Ryan use his bits in the game Fiona asked,
"How do we play with it?"
Ryan was releaved that Fiona was satisfied with his explination and as she asked her question he smiled widely as he took her hand and slowly placed it onto his throbbing cock. Fiona flinched slightly as her brother shivered but since he kept his hand over hers she took hold of his thing and giggled softly as she felt how it seemed to move in her hand. As Fiona seemed happy enough to hold his cock Ryan started to move her hand up and down his dick and through little moans of pleasure he said, 
"Just do this with it Fi, it makes it very happy."
Fiona nodded softly as she started to move her hand on her own and smiled to herself as she realised she cock make her brother pant and purr if she changed how she squeezed his thing and where she touched. As she squeezed softly and rubbed the base Ryan would purr loudly but if she suddenly touched the top he would let out a gasp and pant more. Fiona was rather enjoying the control she had over her brother and was completely focused on figuring out how Ryan would react to each of her different touches.
Ryan was loving the way his sister was teasing him and was so close to climax when he suddenly realised the danger he was in. If he wasn't careful he would spill his seed onto Fiona's clothes and leave solid proof of his little game. In a moment of panic Ryan pulled away Fiona's hand and said,
"Wait, stop."
Fiona jumped as her brother suddenly ripped her hand away from his thing and looked up with wide eyes as she worried she had done something wrong. Ryan saw the look on her face and throghh his panting he smiled softly and said,
"Sorry Fi, you were doing great but I forgot something. To play this game we need to take all our clothes off, is that ok?"
Fiona didn't understand why they would need to be naked to do this game but she was so releaved that she hadn't done something wrong that she simple started to undress as she said, 
"Ok."
As Fiona stripped for him Ryan ripped off his top and quickly moved their clothes safely away from any potential mess. With Fiona now naked Ryan was tempted to push their game to the max and take her on his bed, but he knew that would be much to far to soon and he took a deep breath to calm himself before saying,
"Alright Fi you can start touching again, if you do really good something special will happen."
Fiona got all excited when Ryan said something special would happen and quickly started to rub and squeeze him again as she giggled happily. Ryan smiled widely as his sister once again started to touch his cock and purred loudly as she brought him closer and closer to climax. After only about a minute of play Ryan let out a gasp and bent slightly as his body tensed in orgasm. The second Ryan's body convulsed Fiona stopped her hand and smirked as she realised she had managed to make the special thing happen. Then out of nowhere something hit her neck and chest and she only realised what was happening as she looked down to see what it was and caught sight of another shot of cum firing out of Ryan's tip. As she realised that this stuff was shooting out of Ryan's thing she let of an ewww and squirmed away,
"Ryan what's that, did you just pee on me. That's gross!"
Fiona clearly wasn't to happy about being hit by Ryan's cum but Ryan could only pant as he tried to catch his breath after his best ever orgasm. As he finally did so he looked at Fiona with a smile and said,
"Calm down it's not pee. It's called cum and it only come out when something makes my thing really really happy. It also makes me feel amazing so it isn't gross its great."
Fiona still was to happy about it but since it wasn't something to gross, like pee, she relaxed and said,
"Ok but get it off me please."
Still purring happily Ryan grabbed his boxers and used them to wipe off Fiona's fur. Once he had gotten the residue of his seed off her Ryan gave her a little sniff and quickly went off to get some of her perfume. After a few sprays Ryan could only smell her fruity perfume and as he smiled widely at her said, 
"thanks sis but remember that you can't tell anyone about our game."
Fiona smiled as she wrapped her arms around Ryan in a tight hug as she said,
"I know, it's our secret game. Can we play one of my games now?"
Ryan knew Fiona was up to something when she hugged him and as she asked to play a different game he hugged her back and said,
"Alright but first lets get our pjs on."
