On top of you

“Turn around” you commanded, causing Sarah to stop in her tracks.

She took a couple of seconds to realise what you wanted but she did as she was told and turned herself around, repositioning herself so your dick was in front of her face and her pussy was hovering right above your face. You had only done this the one time with Sarah previously and you now had to worry about the added distraction of Sarah going down on you at the same time.

Sarah also seemed hesitant to start as your crotch was still not getting any attention and considering you were supposed to be the more dominant one out of the two of you, you decided to make the first move. You reached out and grabbed hold of her ass, placing a hand on each cheek and pushing her down closer towards your face. She offered no resistance as you pulled her towards you, watching as she lowered herself towards you with her crotch still wet from what your fingers had been doing before.

You stuck out your tongue and started to tease her by kissing her upper thighs, moving your mouth closer and closer until you could taste her juices on your lips. You could feel Sarah start to shiver as you started going down on her in earnest, prompting her to bring her attention towards you. You tensed for a second when you felt something happening at your crotch without being able to actually see what but the feeling of Sarah dragging her tongue up from the base of your shaft and up to the tip, quickly made you relax again.

You were glad that you got a headstart in bringing Sarah closer to a climax as she was definitely getting better at giving blowjobs, enough for you to take notice anyway as your focus drifted away from helping Sarah get off and more towards what you were receiving. As you relished in the feeling of her lips along your cock, you were broken out of your trance when you thought you heard a smirk coming from Sarah.

It was only a moment but if she was treating this like a competition, similar to how she treated most things between you, then you knew she was probably loving that you were too caught up in her skills to worry about her. Her streak of competitiveness brought you back to reality and with a gasp of surprise coming from Sarah, you started to attack her in earnest. Sarah only seemed to respond to your eagerness with more passion of her own, stopping the licking she had been doing previously and placing her lips around your dick, pushing herself a little further with every bob up and down that she took.

You both focused on each other as the seconds passed, both trying to up the ante and get the other one to be the first to cum. You heard Sarah gag for the first time as she reached her reflex and now that she knew where her limit was, she used everything she had available to get you closer to a climax. She brought one of the hands she was using to hold herself up, down towards your balls and tried to add any extra pleasure to coax the cum out of you.

Not looking to be left behind, you removed one of your own hands away from her ass that you had still been groping and started to move your fingers slowly on her clit. The effect was almost instantaneous as she moaned on your cock, vibrations moving along your shaft to give you an added reward for your effort.

Neither of you were now treating this like a romantic cuddle and an almost animalistic nature came over the both of you, pushing you forward in an attempt to outperform the other. The first signs of your impending climaxes came from Sarah first. You could feel her legs at the side of your head start to quiver and her attention on your dick start to lighten. You had been nearly at the tipping point yourself and with the brief moment that she took to pause, you doubled down and sped up the movement of your tongue and put a bit more pressure on your fingers working her clit.

That was all it seemed to take as Sarah started to moan even louder with your dick still between her lips, feeling what you were doing to her as her legs tightened around your head. She tried to push herself away from your tongue but with your hand still on her ass, you **** her onto your face, pressing your tongue as far as you could when she started to cum.

You wanted to push it even further and make her cum even harder but in the mix of it all, Sarah's arm gave way and pushed her forward, forcing your cock further into her mouth and past her gag reflex. With your cock now in her throat coupled with her endless moans as she went through the throes of pleasure, you could no longer hold back as you started to cum, shooting straight down her throat that felt like it was milking you as her muscles tried to push you out.

At some point, Sarah managed to right herself and your dick was freed from her mouth, the colder air now hitting your shaft as you were still in the middle of your climax, not caring about where your cum landed as the waves of pleasure still flowed through you. Sarah didn’t seem to care either, as she kept her pussy against your face, grinding herself on your tongue as she worked through the climax of her own.

You both eventually passed the peak and slowly started to calm down, with Sarah moving forward slightly and collapsing on top of you, without your dick in her this time. You didn’t care about her lying on you and worked on catching your breath after almost being smothered in your sister’s crotch and feeling her heartbeat racing through your contact let you know she still needed a few more moments to rest.

“You okay?” you asked, hearing her try to clear her throat a couple of times, hoping you hadn’t caused her to have any injuries when you slid into her throat.

“Probably” she replied between laboured breaths, somehow finding the energy to turn herself around and drag herself up the bed next to you.

She placed her head on your chest and you finally got to see that some of your cum had indeed landed on Sarah and although most of your cum had indeed been deposited inside her stomach, she would likely need to clean herself before she went to sleep. Sarah didn’t seem bothered by it for the moment so you let yourself relax next to her, placing your arm around her and making sure she was happily cuddled up against you.

Over the next few minutes, the both of you stayed silent and seemed content to let time pass in each other's arms, with Sarah only breaking the silence after she let out a yawn.

“I wish we could stay like this forever” Sarah said, sighing as a dose of reality hit her, telling her that that wasn’t possible.

“I don’t know about forever but you can sleep in here tonight if you want?” you suggested, offering her a compromise.

She seemed happy with the idea at first but then a few worries seemed to surface in her thoughts and the light in her eyes slightly dimmed.

“I would but what about Lucy and Mom?” she asked, troubled about the idea of her getting caught in the middle of the night.

“Lucy is already in her room and I don’t think Mom will be up for too much longer if she isn’t already in her room. Plus I’ll probably be waking up before anyone and if you can handle getting up early then you can sneak back into your room for a little extra rest. Even if they did catch you, you could just say you had a nightmare or something” you explained with a shrug, tempting her to spend the night with you.

The look on her face told you that you had swayed her but it seemed your argument had been a bit too persuasive.

“You're not gonna try anything while I’m asleep are you?” she teased, poking you on your chest.

“I’ll keep my boxers on if you're worried about that but I can’t guarantee that my hands won't be grabbing things in the night” you joked back, running your hand that had been wrapped around her, up and down her arm.
