Yes

"Well ok," you hear, and keep listening to make sure he's really gone.

After you were sure, you realised you really needed to pee.

You quickly rushed over to the toilet, and sat down, you let out a sigh of relief as you let your urine leave you, it felt alien, but not too different. But there was something else, something leaking from your pussy.

After wiping yourself, you returned to the mirror for a closer look. You sat on the floor, and spread your legs. A wave of disgust washed over you, as you inspected your mothers pussy, there was no world where you ever wanted to see that, but you had to find out what the feeling was.

You slid a slender finger down your mothers vagina, it felt bizarre, but slightly pleasing, it started to moisten. You finger then made contact with a substance, a viscous substance. You scooped it out, and put it up to your face.

It was thick, white, and sticky.

"Oh fuck!" You swore, realising what it was.

Cum.

You never really wanted to think about your parents doing it, but finding what was, presumably, you fathers semen, made your mind wander.

You supposed it wasn't really bizzarre, you were your mother now, but it was you in there.

And then it dawned on you.

Cum in your pussy also means theres a chance you were pregnant.

Fuck, you couldn't be pregnant. You were a 19 year old man, or you were.

Speaking of 19 year old men....

"WHAT THE FUCK!" You heard from down the hall...
