Upside-down mouth-fuck? Yes please!

You stand up, make a hand-seal, and then will yourself to be naked, knowing full-well that Saria wouldn’t think anything of it. Once your hard cock was exposed, you walked in front of the TV and begin to rub your erect genitals against your sister’s face. It isn’t long before she starts to pant, her chest heaving and her legs squirming.

“I hope you don’t mind me blocking your view.” You say with a grin.

“I wasn’t really watching anyway.” She replies and then slides her tongue out of her mouth to lick your throbbing member, “I think I like watching this a lot more anyway.”

“Oh, so you like my cock, huh?”

“Oh no, it’s like a train-wreck you know? I just can’t stop looking.” She smirks a bit from her quip, having returned the one you gave her a moment ago. You hear her inhale sharply. “An olfactory train-wreck too, might even be a wreck to my taste-buds too.”

“So you’re saying that if I just slid this between your lips you might not be able to stop tasting it?”

“Mmm,” her response was short and she bit her lower lip, “possibly. There’s only one way to find out.”

That was all the encouragement you needed. With a bit of effort, you began to slide your swollen cock between her soft lips. Her mouth was a bit small so it barely fit, but that just made things even better when you got in. You weren’t sure if she was able to deepthroat, and you honestly didn’t want to hurt her so you only slid it in partway and begin to slowly slide it in and out. The feeling of dragging it between her tight lips was already pretty intense.

She seemed to mumble a bit and you were about to pull out so she could speak, but before you could you felt her hands on your ass as she pulled you further into her mouth. You felt yourself enter her throat with little resistance. The feeling was incredible, the combined tightness from both her lips and throat were pretty intense. After pulling you forward so that your entire cock was sheathed in her mouth, she let her hands drop again. Apparently all she wanted to show you was that she was capable of taking the whole thing.

You once again started to slide back and forth inside her lips in long, steady movements. You didn’t really need to go fast, as your second encounter with Ryouna proved, but it was hard to control your movements with how pleasurable the whole experience was. Occasionally you heard some soft whimpers coming from your sister, and peering over to her dark blue panties you realized that she was enjoying this quite a bit too.

Your eyes wandered back down to her neck. You felt some satisfaction as you saw the bulge from your cock slide back and forth along her neck. Then your eyes drifted upward to her breasts. In the commotion one of her breasts had become completely exposed, revealing a tiny, rock-hard, dark pink nipple. You realized you were in prime position to just reach over and grope them while you fucked her throat, so you did just that, taking handfuls of the amazingly soft flesh and squeezing them a bit roughly. The whimpering became a bit more intense and frequent, and you felt your sister’s dainty fingers dance and slide along both of your thighs.

Before today you never had a woman anywhere close to your genitals, and today alone you had two of the most intense ejaculations of your entire life. Combined with your self-inflicted blue balls on the date earlier, and the fact that your sister’s mouth felt impossibly tight, meant that you were already at your limit for endurance. You were almost positive that your endurance would get much better from now on, but for right now you were already approaching your limit, and fast.

Suddenly you had a realization. Before today you had no idea how much you enjoyed the sound of a woman swallowing your cum, and then proceeding to tell you afterward how good it tastes. You were sure that there were far too few women out there who enjoyed both the sensation and the taste of cum in their mouth. Ryouna seemed to like it, but she was a hardcore masochist, and probably got off mostly on the sensation of being degraded by being made to drink it more than anything. It then occurred to you that part of a person’s perception of reality was their sense of taste…

“It’s normal for all women to find my cum absolutely delicious.” Almost immediately after you said that, your sister started to bob her head as much as she could on her own. Her fingers tightened around your thighs, almost painfully. She was surprisingly strong.

Wait, did she already know that your cum tasted good? Did every woman know? This could get interesting.

Her **** movements brought you to the edge and made you take the plunge as you began to unload between her lips. You heard her whimper with **** delight as no doubt she tasted your cum and began to greedily and hungrily swallow down every ounce that spurted out.

"GULP GULP GULP GULP GULP!"

You came a lot, and she moved a hand to your shaft to milk out every single drop you had. When you were finally spent you started to pull out but suddenly her hands jerked back to your ass-cheeks, and pulled you back into her throat.

What have I done? You thought to yourself as your extremely sensitive cock was plunged back into her moist depths. You didn’t have the energy left to move your hips back and forth though, and as soon as Saria realized this she released you. Your cock left her mouth with a pop and you stumbled backwards onto your butt. You were about to be relieved that she had released you when suddenly you felt her hand on your sensitive member, stroking it.

“Ahh, Saria, it’s too soon.” You tried to reason with her, but she simply looked at you with a grin on her bespectacled face.

“Oh really? Your cock seems to disagree.” It was true, your cock was still rock hard and her hands delicately gliding along its shaft wasn’t helping much. “And besides, I haven’t had my fill yet. Your cum is waaay too delicious.” With that said she lowered her head and slid the cock back between her lips, bobbing her head up and down along its length. While her head was busy at work doing this, her hands continued to stroke the shaft like she was trying to milk you… and she probably was. The feeling of having her working your cock so soon after ejaculation was intense, if you had any more sperm to spare, you knew it wouldn’t take long for it to get sucked out.

You could feel yourself getting light-headed. You mused at how cruel the earrings were for giving you basically unlimited access to all manner of sexual acts with any women you wanted, but they didn’t grant you enough endurance to take advantage of that quality all the time. You felt yourself nearing ejaculation again, but you had no idea if anything would even come out, you had never gone this far before even when masturbating.

With a bit of a groan you started to cum again, and you heard your sister yet again swallow each load. That answers that question.

"GULP GULP GULP gulp gulp… gulp…"

You were fading, the intensity was too much and you felt yourself losing consciousness.

Is this it? Is this how I die? Getting sucked to **** by a semen-hungry little sister?
