Sir Mitch The Third

When I was about 13 or 14, I jizzed on a pizza by mistake while masturbating in its direction, with my parents and siblings upstairs. I just masturbated in the kitchen then suddenly I had to nut. I tried to make it to the bathroom so I could jizz on the mirror or something, but then I fell dickfirst into the pizza box, and came all over it. I suddenly realized I had came on the pizza my family was going to eat so very quickly I took some bleach wipes and wiped down the pizza, I told my parents I couldn't eat due to being full, and they ate the fucking pizza The next day or so, my mother announced she was pregnant, and gave birth to my brother (who has mental problems) nine months later. Do you think I impregnated my mother, or is it just some freak coincidence? Please tell me, I've been haunted for over 3 years now.
