You decided not to make a wish as you wanted to know what would happen, if it was something bad you could always wish it never happened. Your dick had grown to around the size of skyler's entire torso both in height and girth.
When skyler saw your dick, she immediately shivered, you could also see a liquid stain spreading through her pants quick managing to cover most of her crotch, with a large amount of the liquid spreading and dripping out from her crotch. Just from seeing your dick she had become unbelievably horny and was already on the verge of a orgasm. "Holy...your dick is so big and thick, it's so much bigger then my husband's cock. And those balls, god they're the size of entire yoga balls. Probably filled to the brim with hot and fertile seed, eager to be pumped into the womb of a woman. N-not like I want it though, I would never cheat on my husband no matter how enticing your big fat slut maker is. And it would be taboo as we're siblings." but no matter what she said, you could tell she wanted your cock. You pretend to not see the obvious and tell her to just sit and watch the movie as your dick and balls increase a little more in size. The size increase caused the smell of the cock to spread even more and with skyler already imaging the cock inside her while watching the very explicit movie, she was pushed over the the edge and came and squirted through her pants all over the room. "I'M CUMMING, I'M CUMMING SO HARD JUST FROM THE THOUGHT OF YOUR COCK, MY HUSBAND HAS NEVER MADE ME CUM THIS HARD" She shouted and moaned as she kept cumming, slowing down after a few minutes, however her pants were soaked and she was now even more horny. She proceeded to rip her pants off and stood on top of you, crouching abit to aim your cock at her pussy "I need this so badly, my husband can't even compare to regular men let alone you." She then slowly dropped down and the head of your cock split apart and entered her wet and tight pussy. Just from the tip entering her, she squirted again. However you needed more, and forced her down your cock, skyler's eyes roll up as her tougue sticks out due to the immense pleasure she feels. And almost immediately after she bounces on your cock going up and down with high speeds and roughness as if there was no tomorrow, "AHHN~ AH AH AH, IT FEELS SO-SOO GOOD. I CAN'T STOP MY HIPS. I CAN FEEL YOUR BITCH BREAKER FORCING ITSELF INTO MY BABY ROOM. CUMMIIIING~~~~" Skyler's huge tits flail around with each bounce as she continues to orgasm as her fluids spray everywhere. You could feel yourself reaching your limit, you were going to cum and you told your sister, but she started to slow down "NGH ah ah-you C-can't cum inside, we're sibling, HAH ah, and it's n-not a safe day, only my husband can impregnate me" Skyler was not fully broken yet, however you needed to cum. So you force her onto the ground, and put her into the mating press "H-huh? W-wait stop you can't CUUUUUUUUUUUUUMMMMMING~ OHGODOHGOD, IT'S SO BIG BUT AHN AHN HAH~ DON'T CUMM INSIDE ME, AND FILL ME WITH CUM LIKE I'M A CUM DUMPSTER, OH OH IT'S SO BIG, MY HEAD IS GOING BLANK" You were so close but suddenly someone knocked on the door.
It was...
