Suspicious sounds

"Okay, keep your eyes closed, i will tell you what you have to do", you could her a zipper being opened and a little gasp. You were sure that the gasp slipped out of Marks mouth, but Marie said: "Oh, your hands are cold. Could you", she was interrupted and a popping sound followed, "ah, ehm, could you press here a bit."

"Yes, yes Ma'am", intermittently, he pushed the words out of his mouth and you could hear some quiet slurping and sucking, "i think, ah, think this might fit now."

You heard Marie gag, then she gasped: "Huh, yes, wow, i really had to hold my breath. Ah, but now it fits. Maybe i just, guh, gained some pounds without noticing."

"I don't think so", you heard Mark and again quietly but unmistakable an zipper, "you are perfect."

"How gallant, handsome boy", she giggled and then opened the curtain.

'No, please not' was all you could think as she walked out off the cabin. Her tits were only half covered, her nipples completly visible.

She turned on the spot, in front of everybody. You didn't need to look around, you were pretty sure how the other people in the shop would react.

"Marie", you said and panicked a little, "what are you wearing?"

"Lingerie, you prude", she laughed.

"But, but you are half naked, in front of everyone", you stammer.

"This is a lingerie shop, they are used to see half naked woman here, fool", Marie lectured you as if it was the most normal thing in the world. "So, do you like it?"

"Of course, but..." you begun again but Marie walked back into the cabin again.

"Wonderful, that is all i wanted to hear", she interrupted you and closed the curtain again with Mark still inside the cabin, he didn't even left the dressing room. Marie fumbled a bit on the curtain and this time she left a gap. For a brief moment she looked into your eyes, then she turned to Mark again: "Please help me to take this off."

Instead, she lowered herself on her knees and opened his jeans and pulled them down. His erected member flung free. You had to stare at Marie. This was the first time ever you saw the beautiful face of your girlfriend only inches away from a foreign cock.

"Oh it hooks again", Marie said and kissed the tip of his penis. Then she run her tongue up and down his shaft. You watched as if you were hypnotized. She opened her mouth, letting his dick slide in inside her. As you watch your girlfriend, the most beautiful women in the world, taking the member of a stranger in her mouth, you had to admit that you had never seen anything lovelier.

Her head moved back and forth twice and let his cock go then. She spoke again: "Just a little bit more. We are almost done."

You were so aroused when she opened her mouth again for his cock that you almost slipped a moan. You could hardly wait for Marie to continue. You started to rub your cock through the jeans, luckily hidden under the bags. Then she took his dick back inside her mouth. For your pleasure she tried to swallow his whole dick and choked a little bit. It was loud enough for another guy to hear, who stood ten feet away.

Marie stopped her movement, letting his cock go again and stood up: "Thank you very much", she said and pulled up his pants. "I will finish the rest alone."

Mark buckled his pants and wanted to exit the cabin when she grabbed him by the arm and held him back: "I will finish you later."

She had lowered her voice for the last sentence but you could understand Marie clearly and so did the other guy next to the dressing room. Then Mark left the cabin, he tried to avoid eye contact and just left the rear part of the shop, trying to hide his raging boner as good as he could. Marie closed the curtain again and changed back into her outfit, this time she was quick. When she left, she walked over to you. You stood up and she grabbed you head firmly. Marie pushed her lips onto yours and **** her tongue inside your mouth. You were surprised by her action but then you kissed her back. The smell of the strangers dick inside her mouth had been so exciting that you could feel pre-cum leaking from your penis.

"Okay, we need to pay for my new outfits", Marie broke the kiss and walked to the register in the front part of the shop. When she passed the guy who stood near the cabin and eyed her, she just winked and laughed, holding your arm.

Mark waited at the register with one of his female coworkers. He avoided your look while Marie acted like nothing happened before.

When you were about to leave, she said to Mark: "You were very helpful, maybe you could give me your number so i can call you whenever i need some help with my lingerie."

Mark turned red again, his coworkers jaw dropped and he quickly wrote down his humber and handed her the note.

"Thank you, handsome", Marie winked at him and then you two left the shop.
