Yes, she is still alive and with such an opportunity provided, you will used it!

After checking if she is still breathing or not, you sighed in relief upon learning that she is still breathing. But now, an opportunity provided itself to you!

Seeing those colossal breasts going up and down is making you gaining an erection! And with your sister-in-law is completely out cold, this might be the only chance you have!

You locked the bathroom's door, pick her up by her waists and charge your strengthened penis into her pussy!

The feeling of being inside of her is absolutely great! Then, you begin to pull your cock in and out of her of her pussy, resulting in her great bosoms to move up and down due to the **** you are using to penetrate her pussy.

However, you know that you needed to end this very quickly as possible since she might wake up at any moments! So you used all of your strengths and speeds to slam your dick into her wet pussy, causing her gigantic breasts to bounce around uncontrollably!

Enticed by her big bosoms, you used your right hand to lift her back up a little and launch your mouth on one of her big bouncing breasts and begin to suck on it! Soon, she begins to lactate, resulting in you get to drink her milk.

Wanting more, you stopped slamming your dick into her for a moment, gently put her down on the ground before start pumping her in the pussy again with your penis, and then proceed to drink milk from one of her breasts while massaging the other.

Soon, you can feel it. You can feel the head of your penis is assaulting the very gate of her womb!

Closing to the end of this venture, you rammed your penis against her womb's entrance as hard and as fast as possible with the intention of unloading the semen that has been gathering inside of your cock for a while.

And then, the moment has finally arrived! Without hesitation or even a second though, you bombarded her womb with all of your semen, filling it to the brim!

As you are cumming inside of her, her ovaries also dropped a pair of eggs in there. Soon, they are stormed by your sperms. And by the time you finished cumming inside of your sister-in-law, they have been penetrated, fertilized and firmly taken roots within her womb.

Sometime later after you satisfied your lust with her breasts and her body and clean up her body to erase all traces of you taking advantage of her earlier, your sister-in-law finally regained her consciousness.

"Hmm?" Your sister-in-law moaned as she's touching the place at her head where it collided with the walls.

"Ouch!" Your sister-in-law yelped after touching the location on her head where it hit the walls earlier.

"Hey! You're okay? What happened?" You asked her back with genuine concern.

"I'm fine. Just a little... dizzy. Ouch!" Your sister-in-law said as she's trying to get up but the pain at her head is a bit too unbearable for her, having no idea whatsoever that new lives are being formed within her after you took advantage of her earlier.

"Here! Let me help!" You said as you offered your right arm and help her get up.

"Tell me. What was the last thing you remembered?" You asked her back.

"I... was in the showers. And... the towel stuck... I pulled it a little too hard and... pitch black..." Your sister-in-law tried her best to remember what happened.

"Okay, let's get you to the hospital then." You said as you take her to meet your brother and the others and inform them your version of the story of what happened at the toilet.

Not long after, your sister-in-law has been taken to the hospital to check on her body. And lucky for you, the doctor and the nurses are focusing on her head and not at her pussy or somewhere else on her body. And since it is too early to tell because you just cum inside of her not even a day ago, they never realized at the moment that your sister-in-law is pregnant with your children in her belly.

After that, nothing else happened, no ones but you know of the incident at the toilet and your sister-in-law has no idea whatsoever that you possibly knocked her up by taking advantage of her after she is fully recovered a few days later after the Thanksgiving.
