Pinkie Pie watched you with unblinking ocean colored eyes.
You sat on the floor of her bedroom watching her just as intensely in return.
Time seemed to nearly stop.
The world seemed to merely fade away.
Pinkie nodded, the right words suddenly found.
“Sex?” She snorted cutely.
"Male." You answer without hesitation.
Maybe Pinkie had trouble telling by your appearance, she's never seen a human woman after all. Or maybe she had a form to fill in.
