You get a surprise

You let her drag you mindlessly through the empty hallway to the nearest restrooms as your eyes never waver from her exposed ass cheeks alternating up and down with each step. You could see her thighs were still shimmering from her pussy juices that had escaped during your impromptu 69 session. You feel a tinge in your loins as you pinch the bottom of her exposed cheek to cause her to coo and then giggle as she said, “So that’s why it felt a bit drafty back there. You should have said something sooner, bro.” She made no attempt to fix even after saying that as you both passed by few more theaters and didn’t notice a single other person upon arriving at the ladies restroom.

You let go of her hand as you say, “I’ll let you get yourself cleaned up, sis.” She stands there as she looks at you with an inquisitive look and opens her mouth but says nothing. She turns around and heads inside as you enjoy every second of the slow trot of her ass cheeks until she disappears around the corner. You exhale and decide to lean against the wall. You think to yourself: (This day has been so surreal…it’s almost like I’m dreaming). You pinch your side just to be sure and the sharp pain means you are clearly awake. That means that everything that happened to you earlier in the theater and every interaction with your sister has been very real as well.

You are taken out of your thoughts when you hear, “Pssssst! Earth to Aleeeex!” You collect yourself as you see her head poking around the corner as she said, “Ah! Took you long enough, bro. I said I need your assistance so come in here.” You began to fumble your words as you were unsure if you could enter the woman’s bathroom. She saw the indecision as she continued, “Chillax, bro. No one is in here besides me. So hurry up before I decline my invitation.” Her head disappeared as you wracked your brain for a few seconds of the possible outcomes. You exhaled and trusted that she wasn’t setting you up with a prank since she has not done anything like that today.

You take careful steps in as your shoes hit the tile floor slowly. You feel your heart beating over entering the women’s restroom as if it was a forbidden grotto. You chuckle and realize you’re actually worried about being labeled a pervert or sex offender more than anything else. You finally get around the corner and see the bathroom empty, leaving you confused if maybe you went into the wrong bathroom in your frazzled state. You say, “Hellooo? Sis, you in here?”

You hear her voice chuckled and say from behind one of the closed stall doors, “Guess what’s behind door number one?” You chuckle as you turn around to see the door slowly creaking open slowly showing her bare leg and arm, more naked skin is showing where her top and skirt should have been until you see a naked boob and her bare hip. Your erection was roaring back to life as more of her naked skin became visible from behind the metal door. With the door completely opened, you feel your mouth drop open as you take in her completely naked figure for the first time.

She slowly sauntered over to you with hands at her side wearing nothing but her lustful grin as she said, “Didn’t expect that, did you bro?” She put her fingers under her chin to close your agape mouth as she squatted down next to your erection as she said, “Hole-ey shit…you must really really like me, Mr. Poke poke. Does he like me, bro?” She asked you as you could only nod. She giggled and said, “Do you think you could help me ‘clean up’?” You watch her bare ass move to the counter and stick a leg up on the counter as she turns her head to gaze at you. She spoke with a soft, sultry tone, “…I have a spot…I can’t quite reach on my own…” You see her pussy lips in all of their naked splendor as you swallowed down some saliva for your dry throat. You feel your dick threatening to bust out of your shorts as you stood there admiring her nudity and exposure.
