It was still early in the morning, and Peter was waking up. He opened his eyes, and immediately realized that something was wrong. He wanted to sit up, but was unable to. He raised his head, and saw that he was tied spreadeagled to the bed, stark naked. There was no blanket, no pillows and - most importantly of all - no Ana.

    He wanted to shout for her, but all that emerged was a muffled grunt. His mouth was stuffed with clothing and his lips sealed shut with broad stripes of sticky tape. Shit, he thought. What's happening? How did he end up like this?

    He could hear footsteps outside the bedroom, and in stepped Ana. Still dressed in that gorgeous slave outfit she had worn last night: A small black, striped top, a short skirt, black silk stockings and pumps. Her hair a lovely shade of ginger.

    Her eyes blazing. Her shoes were hard and loud against the wooden floor as she strode over to the bed and looked at him.

    "How dare you!" she hissed. "How dare you humiliate me like that, in front of all our friends!"

    Peter wanted to explain, but she put her finger against the tape covering his mouth. "Shut up," she said. "I don't want your excuses. I was there, I saw what happened."

    A twinge of fear shot through Peter's stomach.

    "You and that big-titted blonde. Your hands all over her ass. Your dick bulging. Have you grown tired of slim, young girls like me? Huh? Is that it?"

    She got onto the bed, and placed herself with one knee on each side of his chest. Now she was looking straight down at him, with an expression he had never seen in her before. His tender, shy submissive Ana had turned into a tigress: Wild, angry, jealous and vengeful.

    Peter wanted to explain that nothing had happened, but didn't dare challenge her again. Instead he did what she usually did for him: Complied, went quiet and waited for what the master (or mistress, in this case) would do.

    "So," she said. "You will pay a price for this. You have talked about how men also get off on asphyxiation, and now you willl get the chance to show me."

    She pulled out a plastic bag from her bra, and slowly pulled it down over his head. Peter felt a twinge of panic as the bag passed his nose and mouth, pulled in vain against the strong ropes and realizing that there was no way in hell he hould be able to pull the it off himself.

    He was completely at her mercy. He could still see her through the transparent plastic, which gave him some comfort.

    "Since I'm a better person than you," she said. "I've decided to give you some enjoyment in the last few moments of your pathetic life."

    Ana had a roll of tape in her hands, tore off a long strip and wrapped it tightly around his neck. Now the bag was sealed, as was his fate.

    He knew it, he had seen it happen to other people. He would have about two minutes before panic set in, then maybe two more before blackout and death. Peter looked at her pleadingly through the plastic.

    But there was no mercy in her eyes. All he saw was a weird, lustful glint. She rose and stood upright above him. Now he could see under her skirt. She was naked, and he suspected that the clothing in his mouth was her cum-soaked panties from yesterday.

    He was still getting enough air, and tried to keep his breathing slow. But he felt a stirring in his groin that would jeopardize that strategy. Fuck! He was getting hard, and fast.

    "Look at your cock," she said. "Does it long for my pussy?"

    Peter nodded vigorously. Ana lowered herself to a squat, her cunt now just inches above his rock hard member. Oh god, he could feel the oxygen starting to run out. Every breath he took from now on would be harder, and so would his cock.

    Deep in the oxygen-deprived Death Zone, the only thing that mattered to him was her cunt. He would die gladly if he could only penetrate her tight little pussy one more time, let his cum fill her as his last -

    Ana rose, jumped off the bed and strode to the door. "Bye, Peter. Enjoy your last, frustrated blue balls. Perhaps you should think about that pretty blonde when you die?"

    She slammed the door behind her, and he was alone with his huge dick. He stared at it, red and throbbing with veins bulging. His legs were to wide apart to squeeze it, his hands helpless and blue from pulling too hard on the ropes.

    He thrust his hips in the air, trying to cum. Oh God, he wa so frustrated! His breathing was becoming shorter and shallower, each lungful of air less satisfying than the last. He felt his panic grow, but his horniness was stronger.

    Peter's thoughts drifted to Ana, he imagined her pink lips around his cock, draining his cum one last time. Oh, how he wanted her! He felt his lungs burn and his head go dizzy from CO2-drunkenness, he pumped and pumped and pumped his tits while he cried Anas name behind her panties.

    Then the darkness closed in.

Peter sat up with a gasp, his heart pounding. Wow! What a dream, he thought. For a moment  he was unsure, then he saw Ana sleeping beside him. He felt a wetness in his groin area. There was cum everywhere, the result of his very wet dream.

    Ana stirred, opened her eyes and looked at him with a smile. Her hand moved, and felt the wetness. She looked at the flecks of cum on his belly, thighs and the bedsheets.

    "Looks like someone had a fun night," she said as she bent over and licked up his cum.

    Peter looked at her and thought about how scary sexy the dream had been. Ana would never do something like this in real life, would she?
