You cum in the changing room

Your head swivels around. Seeing the clerk distracted, you make a dash for the changing room. As soon as the door is shut, you feel Adela's hands dance around your belt buckle. Once it's undone, Adela yanks your pants down and starts kissing your flaccid member. It soon grows erect, allowing her to grip your shaft and seal her lips around the tip.

Her head bobs back and forth as you grit your teeth, trying to hold in your moan. She wastes no time, moving along your shaft with haste. She knows that this needs to be quick, and so do you. Part of you wonders if someone saw you enter the change room, or if anyone can notice there are two sets of feet at the bottom of the doorframe.

As Adela continues, you hear footsteps nearby. Your heart races whilst you wait for the inevitable knock. You try to formulate a sentence in your brain as your hand slams on the door, hoping to keep it shut in case anyone tries to intrude. That's when the knock on the door comes.

Adela's mouth pops off of your cock. "Just a second."

She then stands up, so you shoot her a puzzled look. Then, she tugs her pants down slightly and grips your cock. As she strokes, she aims your tip at her panties. Her lips meet with yours whilst her hand stroke with vigor, determined to make you unload. Every stroke brings you closer and closer to climax, but you swear it won't be fast enough. Again, you fear that you'll hear a knock on the door, something that fills you with equal fear and excitement.

Finally, you erupt, spurting into her panties. She continues to tug, ensuring you're completely drained. That's when that much-feared second knock comes.

"Coming out now." Adela calls out.

She opens the door and you follow her, finding another clerk who likely puts two and two together. You both leave the scene of the crime and pay for Adela's new outfit. Now out of the store, the two of you start to giggle before you head to the exit. Now walking back to Adela's place, you say "So, did I ruin those panties?"

"Nope. Cuck special."

"Well... whatever pays the bills."
