‘How? Why? When? How long has she had it? Is it really real? Who else knows about this? How’d I not know about this? Is this why she’s been distant lately? What the fuck, mom and dad? Does it really work like a guy’s? Is she a guy? Is this why her relationships ended? Does she pee standing up? Is she able to reproduce with it? Wait, was she really jerking it before I got in here? And was it really that big? How big is she?’
The last question is what captivates her the most. She saw it when Natalie’s knees were up under the covers. She then remembers the tickle fight and remembers that it was big enough to mistake for the remote. Her curiosity peaks and now she needs to know. But how does she get her answer? She can’t just wake her up to ask her. She’s gotta find a way to figure it out.
Then the thought of a possible method for her to know appears.
‘No. That’s too far. She’s my sister. That’s completely wrong. That shouldn’t even be a consideration. I don’t care how curious I am. I’m not giving my own sister an erection.’
As she has this tirade with herself, her hand subconsciously starts rubbing at Natalie’s flaccid penis. Realizing there’s no going back now and hating herself, she decides she might as well go with it. As she rubs her hand back and forth on Natalie’s appendage, it starts to slowly react, getting slightly bigger with each action. Monique instinctively grasps her sister’s growing shaft and slowly starts stroking her hand up and down her length.
Eventually, Natalie’s cock gets fully erect, leaving Monique in shock and awe at what she’s seeing as she stops her hand movements. Not only does this prove that it’s actually real, but it answered her burning question. And she’s satisfied with the result. 6 ½ inches of throbbing flesh just inches in front of her. This both excites her and confuses her on how her sister is bigger than every guy she’s been with.
Now she’s torn. She doesn’t wanna leave her like this. That’d just be cruel. But she also doesn’t wanna get her own flesh and blood off. That’s just weird and gross. But the more she looks at it, the more favorable the latter option seems.
‘I mean, what kind of selfish, heartless sister would I be to leave her in this much discomfort. I got what I needed and so it’s my responsibility to give her what she needs. It’s only right. She’s taken care of me my entire life. Time to take care of you now. But to not make it too weird, I’m only gonna give you a hand job.’
She starts jerking Natalie’s cock again, this time going a bit faster than she was. She likes how it’s so warm in her hand. So big, so warm, so…delicious looking. Monique realizes where her thoughts are going and snaps herself out of it. She can’t lose track of her motive: make her cum with her hand and leave.
As she refocuses on her objective, she can’t help but to notice a clear fluid emerging from the tip of Natalie’s penis. Curious about the fluid, she takes the index finger on her free hand and wipes it on the tip, gathering the fluid. It’s a bit sticky. She plays with it a bit, squishing it between her thumb and finger. She then brings it to her nose, taking in the smell of the mysterious liquid. It’s got a strong smell, but not unpleasant. She slowly brings it to her mouth to taste it. Once she does, she finds that she really enjoys it, licking her finger and thumb clean.
She turns her attention back to the throbbing member in her hand. She then notices more of the fluid appearing. With her newfound love for the taste of the fluid, she brings her face to the tip of her sister’s dick and licks the essence. But this time, it tastes even better to her because it was mixed with the taste of Natalie’s member.
‘Well, I guess it shouldn’t really matter how she gets off. And if you think about it, this isn’t any different from licking frosting from her finger when she makes cakes. So it can’t be that weird, right?’
She then wraps her mouth around the head of Natalie’s dick, circling her tongue around it and continuing her jerking motion as she gently sucks on it, savoring the taste of it along with the fluid. This causes Natalie to slightly shift and let out a light moan, causing Monique to stop in her tracks. Once she settles down, Monique slowly returns to her actions, enjoying the slight moans she’s getting as a reaction.
She eventually starts bobbing her head up and down the tip, taking more and more of Natalie’s member in her mouth, managing to get half of it. She then removes her hand and completely lets her mouth take over, using her now free hands to push her legs farther apart for better access. Natalie gasps and moans with these actions, giving Monique a boost of confidence as it’s confirmation that she’s doing everything right.
She then hooks her arms under Natalie’s thighs, taking her deeper in her mouth in the process. Natalie’s noises of approval grow more and more frequent. But then she starts mumbling in her sleep,
“Yeah. Just like that. Suck on it.”
Monique hears this and it boosts her confidence even more. She’s doing so well that she’s made her subconscious give her praise. She starts sucking harder and faster, earning more moans from her sister.
“Yes,” she moans out, “Yes. Keep going. Just like that, Monique. Suck on it just like that. Fuck. Your mouth feels so good, Monique. Yeah. Take it deeper.”
This catches Monique off guard.
‘Is she dreaming of…me?’ she questions, ‘Is this what gets you off? You like your little sister taking you in her throat? Wow. Such a naughty big sister you are. I bet you were stroking your cock to me earlier, too, weren’t you? And every other time where you either needed to ‘work’ or ‘use the bathroom’, you were just pleasuring yourself, huh? You want me that bad? Is this what you wanted? Well, let me make your dreams come true.’
Monique takes more of Natalia in her mouth, reaching the base of her shaft, earning more praises from her. She continues bobbing her head faster and faster. She then snakes her hands up her sister’s body, reaching under her shirt and grabbing a hold of her breasts, squeezing them and pinching her nipples, elevating the pleasure.
Monique soon feels Natalie twitch in her mouth. She starts bobbing as fast as she can.
‘You gonna cum in your little sister’s mouth? Huh? You gonna shoot your warm, sticky, delicious cum in your sister’s awaiting mouth? Do it. Give me your milk, big sister. Let me drain your cock like a good girl. Cum for me. Let me taste your cum.’
Her silent pleas are soon answered as Natalie lets out a moan and shoots rope after rope of her semen into Monique’s mouth. And Monique greedily swallows it all, savoring the taste of her sister’s cum. Monique then bobs a few more times, ensuring she gets every last drop of Natalie’s essence. She then takes her cock out of her mouth with an audible pop as she admires Natalie’s satisfied look.
She then steps out of the bed before covering her up with the cover right beside her before kissing her cheek and whispering,
“I love you. I’m glad you liked that. And I can’t wait to do it again tomorrow night.”
