Return the favour

You knew that Sarah seemed to derive pleasure from being used by you and it felt amazing to take advantage of that, at least until the scales started to tilt too far in your favour. It felt like you were slowly unlocking more of her body to play with as you progressed through her levels but you still wanted to keep the same brother/sister relationship that you had had before you started acting like a jerk.

Even while you were trying to rest, Sarah had remained where she was sat before, still between your legs as if she was waiting for your order to leave her post. Getting her to follow your orders seemed to be a reward in of itself for her but you were pretty sure she was gonna like this one a lot more than usual.

“Stand up” you declared, trying to keep your voice as monotone as possible as you pushed yourself back up into a sitting position.

Sarah did as you asked immediately and although she wasn’t sure of what you were about to do, her eyes seemed to sparkle at the opportunity to please you.

“Strip” you ordered, making her remove her skirt and then her panties as she followed your command, taking a brief moment to put your own jeans back on.

You held out your hand after that, expecting her to pass you her panties but this seemed to be the first hint of hesitation that you got out of her. She still gave them up despite her earlier caution and the blush on her cheeks showed that she was getting embarrassed. You didn’t realise why until you spotted a prominent wet patch right where her crotch had been, soaking the material and looking at her pussy confirmed that she was still equally as excited as she was before.

The embarrassment seemed to only turn her on even more as she started to squirm and rub her legs together as you continued to stare at her. No matter how you looked at her you couldn’t find a single flaw with the view in front of you and you knew that you wanted to get your hands on her again. You pushed yourself towards the head of Sarah’s bed and beckoned her to do the same. Even with the stricter atmosphere, she purposefully crawled up her bed as slowly as possible, giving you plenty of opportunities to admire her as she worked her way towards you.

At first she sat down at the side of you, resting herself on her elbows so she could pose and give you as much access to her body as she could manage. You leant over and placed yourself over the top of her before kissing her once again. Sarah eagerly received your kiss and you could feel her steadily start to relax, lowering herself as the kiss between the two of you continued.

You broke the kiss and moved yourself slightly away from her once you felt she was comfortable enough to move onto something new. You looked over her body and couldn’t resist running your hands over her as you straddled her thighs, giving you plenty of access to her tits that you had increased in size.

“You're not allowed to move from now on unless I say so, got it?” you said, wanting to phrase it as an order but still giving her the option to decline.

You knew she wasn’t going to though and a very rapid nod of her head proved that to you.

“Good girl” you responded, getting a blush out of her as you continued to fondle her body.

You lowered yourself back down closer to her after fulfilling your desire to play with her tits but this time, you brought your lips towards her neck and started to kiss her body. You didn’t stay there long as you slowly moved lower, kissing her collarbone and making your way down to her chest. Sarah seemed to expect you to stay there for a while and although you did spend slightly longer there as you kissed her nipples, you continued moving your head lower.

You had to manoeuvre yourself and shuffle backwards as your lips trailed away from her chest, placing yourself between her legs as you reached her stomach. You made it to just above her mound when you looked up, wanting to confirm Sarah’s reaction. Her eyes were glued to you, watching every movement you made as her breathing got rougher. You saw a hint of nervousness from her but you could see no indication that she wanted you to stop.

You continued moving your lips but moved away from her pussy, kissing her thighs to try and tease her as much as possible. You knew you had gotten a power to help with kissing from the KDK and although it had eluded to improvements in other areas you weren’t too confident in your skills. Exactly like Sarah, you had virtually no skills in oral and teasing her like this was your way of working up the courage to properly begin.

As you moved your lips closer to her pussy and towards her inner thigh, you saw Sarah's hands were clearly gripping at the covers, mirroring your earlier movements and giving you a bit more confidence in what you were about to do. You slowly started to kiss her lower lips, running your tongue against her and tasting for the first time.

It was different from what you had expected after you had read various things online although that was the main word on your mind the taste was far from unpleasant. You began in earnest at that point, using your hands to separate her legs further apart and giving you more access to play with her pussy. Sarah's moans were slowly rising in volume and you took that as a good sign to continue what you were doing. You experimented as you got more confident with your movements, moving your tongue deeper as you sought out any noise of approval that might escape Sarah’s mouth.

Sara seemed to realise the volume of her moans was starting to get to a level where other members of the house were likely to hear her and moved her hands to cover her mouth. You were thankful that she had done so but her disobeying your earlier order to stay still only made you double down in your efforts to tease her even more.

You brought your hands into the mix and started to finger her, curling your fingers slightly to try and bring her as much satisfaction as possible. You considered using the vibrator Sarah had in her room that you had previously found but it wasn’t in hands reach at the moment and Sarah probably wouldn’t appreciate you stopping to look for it at a time like this. Your fingers were now occupied as you used your tongue and moved slightly higher, finding and focusing on her clit. You ran your lips over it with gentle contact before slowly upping the intensity.

Sarah’s reaction definitely gave away that she was loving what you were doing as she moved one of her hands away from her mouth and rested it on top of your head, gripping your hair whenever you did something that was too much for her to handle. That only seemed to work against her as you started to focus on all the things that made her hold onto your head as tightly as possible.

You could tell that she was getting closer as she practically started to grind your face against her crotch and the moans she had been previously trying to hide, were replaced with incoherent mumbling.

“Oh god. Oh god. Fuck your gonna make me cum. God my own Brother. Please please…” she repeated, her vocabulary greatly reduced to only a few words as her arousal continued to build.

Feeling her squirm only made you press on until Sarah started to tense up.

“Oh fuck, I’m cumming I’m cumming” she announced, unable to contain herself any longer.

Up until that point, she had still been trying her best to limit the volume of her voice, but that was all off the table when her orgasm started. She brought the hand still near her face to join the other and used both to hold your head against her pussy. First her legs and then her whole body seems to tense up, raising herself slightly off the bed and forcing you to grab her ass as you continued to pleasure her. Her voice seemed to be caught in her throat, which you were thankful for but her mouth was wide open and ready to start screaming as she finally started to cum.

Fluid rushed into your mouth as you refused to stop licking her pussy, happily drinking it down as you did everything to prolong the experience that Sarah was having. You slowly lowered the intensity after that, changing your focus from her clit and removing your fingers that were still inside her. The grip she had on your head also decreased in pressure as her still raised legs started to tremble, forcing her to fall back onto her bed with a long sigh.

Now that everything seemed to be winding down, you were suddenly hit with the question of how to act. Would putting up the confident front really be the right play to make after what the two of you had done? Or should you do something else?
