You kissed your mom, the woman your girlfriend has become.
At first, you find weird kissing your own mother, but after all this is your girlfriend... and her name is... is...?
This is very strange, you can't remember her real name and the girl who was your girlfriend!! You suddenly stop kissing her.
"What..?" She asked, a little surprised.
"MOM... this is weird. I can't remember your true name, mom, and my girlfriend name."
"What are you talking about, honey? I'm your mom and your only secret lover! Who is your girlfriend, honey? Are you cheating on me?"
"No, you wouldn't understand, this room changed into my mom, but now I can't remember you as my girlfriend that I turned you into."
"A girlfriend? Yes, I ever wished to be your girlfriend and I try to be one." she responded. "But unluckily I'm always your mother. But for you, I am the sweetest mother and your lover, aren't I?"
And then she started kissing you again. Her name is Mary, your mom of course. Why you remembered her as your girlfriend.
Slowly, every memory of your previous girlfriend faded, and was replaced by a similar remember about your mom.
Your first date with her. Your first kiss. Yes, your only girlfriend is your own mother, and you love her from the bottom of your heart. And kissing her very deep, the last thought about your former girlfriend was gone. Or is it?
