Tina's (still her POV)

-Oh! Ohh~~~- Surprisingly, Tom's body is not tired, his tongue keeps arousing your inner walls. Nineteen years of suppression are pouring out all of the sudden: even though you, being a guy, usually have a long refractory period after an orgasm, he already cummed two times at least. While for Tina, you previously found out that indeed women can afford multiple climaxes, as you're now confirming. And, if his cunnilingus blows you away like this, you shiver in anticipation of an actual intercourse. You want, you need to know.

Kim too apparently, since she's climbing his legs. No way sis! You literally jump on your brother's lap, causing him to groan in pain and her to withdraw quickly.

-What?- She squeaks, but you stop bothering about her. Your old dick is pressing, hard as a rock, on your damp outer folds, you just have to spread a bit and... and you're done. You will destroy this final taboo, you will transform your timid, loving little sister into an incestuous whore. And this only feeds your depraved desire. "Tom" looks at you totally twisted, and you laugh at its confusion. Boy, he's so easy. You are, well, whatever.

-T-Tina...-.

-Brother.-.

You brush his beard and then bind your lips to his. His kiss is pretty similar to Kim's, but it's also different, it's more... more masculine. And you feel more excited, no, not just that, more cuddled too, more pleased. You reluctantly depart, his eyes are bright and feverish.

-Is it true? What mom said about you?-.

You arch a corner of your mouth, stifling a giggle. Seems like "you" require more persuasion: who knows, maybe he's sensing you are not really his sister. What would happen if he knew the truth? You have assumed that, being another you, he would have agreed; on the contrary, he may have retained some moral you got rid of. Would he call you a monster, you wonder? Would he despise you? Would he insult poor, innocent Tina? This doubt makes things even kinkier.

-Yes. When I think about you, I, I feel something in my chest, like a terse arrow piercing my heart. Here, listen.- You lead his hand over your left breast. After a moment of hesitation, his fingertips softly founder.

-Do you feel it? It calls for you to heal. I... I love you, big brother.- You slowly spread apart your thighs, staring at him with a fiery glance. He holds his breath while his tip gradually climbs your cooch. Then, in the end, he is fully inside you.

You gape, unable to articulate anything different from a gasp. You guessed, you guessed what? This is another league, another planet, such a pleasure should be illegal, it should be banned! How could you live to this day without this? And how could you, how could you live from now away from it?

Tom grabs your asscheeks, looking up at you from under your tits. In less than a few minutes, he went from being an insecure nerd to a hunk who knows what he wants, and he's now demanding it from you. You lift up a little, feeling like dying for that dreadful emptiness that has been horribly generated, but then you low down and an erotic relief refills you, everything is back as it should be. You bounce up and down, perceiving your unusually long hair waving on your shoulders, getting lost behind that disruptive cycle, and his manly grip grows in strength and firmness.

-Oh yeah, yeah, oh big bro, oh~~

-Tina, Tina...!!! You're crying?-.

"What?" You wipe a tear from your jowl, sensing a whirlwind of emotions stirring your soul: pleasure, joy, arousal, suffering, anxiety, revulsion, you don't even know where Tina ends and you start.

-I'm so happy I'm losing my virginity to you!- You sob while smiling and moving: -I wanted this so much!-.

-Me too!-.

Your upper body needs more attention, thus you protrude your boobs towards his face. He takes the hint and squeezes your right, then he tastes and sucks the nipple. You don't have time to elaborate as another stimulus takes you by surprise, since a second pair of hands slaps your ass and an entire feminine face sinks into your perineum. Once again you can't but moan, completely carried away.

-Oh god!!! Oh god please never stop!!! Please never stop please never sto-oo-oww!!!~~ You tremble all over, feeling a train departing in your crotch and a sticky juice filling your vulva. You quiver once again, admiring your old face gritted with effort, then you just roll off on the floor, exhausted like after a marathon.

You breathe deeply, trying to make sense of it all. You thought you have already done, you honestly thought you were prepared when you came down the stairs this morning. But you weren't. You couldn't. You won't. Ever.

A lock of hair covers your eyes and another pair of lips meets yours. A third body is now enfolded in yours, one of someone who does not wait for you to recover. Her fingers are working on your threadbare pussy, her tongue the same with your mouth.

-Mom...- You whisper. She grins in a manner a mother should never grin.

-You'll learn some respect, missy. In one way or another.-.
