They kissed and hugged each other for a few minutes. She pulled off her bunched-up black skirt, saying that it was in the way. He looked around at the shabby wallpaper and worn carpet, then at his naked aunt with her excessive make-up acting the role of a forty-something year-old hooker.
She rolled away from him. She stood up and pulled on her vest top and stepped into her scanty, leopard-print panties. She smiled at his puzzled expression.
"I need a pee -- I won't be long, hun."
He gazed at her long legs as she stepped to the door. Her tarty panties showed below the hem of her top. The curves of her body were subtle rather than voluptuous, but were well proportioned. Although her breasts were firm and only small, they nevertheless quivered seductively under the thin cotton, and her nipples pressed saucily against it. His aunt opened the door, paused, and returned for her mobile.
"Ring me," she whispered.
"Why, Aun -- Kim?"
"Just do it!" she hissed.
As she stepped into the corridor he heard her say "Hi" -- presumably the hotel proprietress was still nosying around nearby. He rang his aunt's mobile as she closed the door behind her, and after a few moments she answered.
"Hello?"
He began to speak falteringly, but it was clear that she had no intention of listening to him. It was equally clear that the "conversation" was a sham, supposedly from a prospective client, intended to shock the owner of the place -- and to arouse him and his aunt as she played out her part.
"Yeah, that's me. I can't speak for long, hun, I'm with someone now for about the next forty minutes or so."
She paused as if listening to her caller. As he listened to her voice through his mobile, Mark shook his head in disbelief at how far she was taking this play-acting.
"Yes, yes," she continued, "that's what I charge for half an hour..."
He blushed and his stomach churned. He wondered if they would soon be asked to leave, or at the very least, how he was ever going to face the hotel owner on the way out. Still his aunt continued her imaginary conversation into her mobile. Although it was not long since his orgasm, he felt a stirring in his groin.
"Oooh!" she said, knowingly and suggestively, as if her caller had said something especially naughty. "Oh yes, I do that, but it's an extra twenty."
Another realistic pause ensued before she spoke again.
"Yeah. Yeah, I could be there at twelve-thirty. Yeah, that's just off the by-pass, isn't it? Yeah, Yeah, I know it. Number eighty-three? Yeah, I've got that -- and I have your mobile number here. Yeah, I'll give you a ring when I'm nearly there. What's your name? Danny? Okay, Danny, see you at twelve-thirty. I'll look forward to it, too. You have a sexy voice! Yeah. Bye then, sweetie. Bye."
The line went dead. He heard her soft footsteps recede and heard the bathroom door along the corridor open then close. He shook his head and laughed out loud with embarrassment, shock, and amusement.
He heard the faint flush of the toilet, and a minute or two later she returned. She grinned, and as she closed the bedroom door behind her she gestured with her finger to indicate that the proprietress was still around. His aunt laughed quietly. So did he.
He was sitting naked on the bed, but with the duvet pulled across his lap. Even though he had had sex with her several times, the fact that she was his aunt made him feel strangely self-conscious. She smiled.
"Now what are you hiding under here, I wonder... oooh!"
She slipped her hand under the duvet. Her fingers met his flaccid cock and she grabbed it and began to shaft it. He looked at her leopard-print panties and at her well-toned thighs. She pulled his head to her breasts and pressed them to his face, rubbing them against his mouth, his nose, and his cheeks. She yanked the duvet aside.
"Mmmm -- you like these titties, don't you?"
"Oh yeah, I love them. They're so firm... and so well-proportioned..."
He leaned back and shoved his hands up her top. He squeezed her breasts, and tweaked her nipples. She grunted her approval and lifted her top, then leaned forward to proffer her naked breasts to his eager mouth. He pressed his face into her shallow cleft and fondled her orbs, then he dragged his tongue over each in turn, and moved in closing spirals to her taut nipples. He licked them and gazed at the glistening trail of his saliva coating her skin and areolae.
His aunt fondled his thigh, teasing his sensitive skin with her fingernails and gently squeezing his muscle. She took his cock again and shafted it hard and without subtlety.
"Oh dear. I hope we haven't tired him out too much, sweetie... I'm sure he'll wake up again soon..."
She sank to her knees on the threadbare carpet. Her red vest top puckered forward and he gazed inside it at her breasts -- the naked breasts of his mother's sister, but to all intents and purposes right now, the tits of a hooker who was slightly past her prime. To spy them naked like this inside his aunt's top was as arousing as seeing them truly naked.
He watched her hands caressing his chest, stroking his hair and tweaking his nipples. She looked into his face with her heavily made-up eyes. She raised her eyebrows provocatively.
"Would you like Kim to suck your cock again?"
"Oh yes please... oh yeah!"
"Mmmmhh, I love sucking cock -- especially young cock..."
He stared as she lifted his flaccid member to her mouth and licked his tip. He felt a twinge of guilt as he became acutely aware whose tongue was really teasing him and whose mouth was even now engulfing him. Her kneeling posture on the floor gave her a submissive, subservient air.
He glanced around the room at the appropriately dingy curtains and faded wallpaper, and then he looked back at the tartily dressed and made-up older woman who was sucking him off. The images of his aunt, the tart and the seedy surroundings almost made his head swim. He put his hand to the back of her head and massaged her scalp and the nape of her neck. He felt his stimulated cock begin to harden.
"Mmmmhhh, that's nice -- Kim..."
She looked him in the eye.
