Trapped in the Past... As My Own Mother!

I built a time machine that swaps bodies, but I ended up in my MOM'S body! Now I have to act like her or I might not ever be born!
I'm in my parents old bedroom, on all fours while my dad fucks his wife... me.... I feel everything mom would feel.... my tits swinging... the wedding ring on my finger... my wide hips while my dad plows me from behind deep in my pussy... making a baby in ME!
