He could feel the tip of her cock pressing against his asshole. His arms and legs bound to the bedposts of their bed. The silky fabric of her nightie, her undies pressing against his erect cock, the smell of her perfume behind his ears, it was all terribly erotic and his cock exhibited his excitement. He couldn't hide it as much as he might want to.
His girlfriend had come home early from a meeting and she was surprised to find him in her panties, her nightgown, her jewelry. He was dressed like her, admiring himself in the full-length mirror. He had not seen her, initially, and so she watched him. She watched him prancing around, practicing walking like a woman, correcting himself and his movements as he went along. His erection was evident, hard to hide and while she was shocked, she found that the more she watched him, the more erotic she found it as well. It was endearing on some level but she also knew that he would need to be punished for this, she would have to teach him a lesson.
When his reflection finally caught hers in the mirror, he dissolved. He couldn't imagine what to say or how to say it, how to explain what he was doing and why. It was all too overwhelming, so he just stood there. His cock bulging through the nightie, his legs stretching the fabric of her thigh-highs, the gold earrings on his earlobes, making him look foolish and girlie. How could she understand, he thought. How could she know how this made him feel, how complete and whole?
He stared at her dumbfounded. He began to take down the straps of the negligee but she told him, in no uncertain terms, to leave it on.
"You want to know what it feels like to be a woman?" she asked. "Well, I will show you. Lie down on the bed, face down, spread your arms and legs. I will not stop until you understand, fully, what it is like to be penetrated, no matter what protests you make. Tying you down will ensure that I can finish what I start."
He slowly made his way to their bed, crawling on the bed until he was centered, then lying down, spreading out his limbs. He then waited. He couldn't admit to himself, much less to her, that this is what he dreamed of, fantasized about, wanted more than anything else in the world.
She took four of his neckties, circled one around each limb, so that he wouldn't be able to slip out of them and anchored him, securely, face down on the bed. No words were exchanged between them. It was eerily silent as she went about her work and as he prepared for what was to come.
He was already hard, and lying on the bed, his cock rubbing against the silky fabric only made him more excited. He couldn't imagine what she was going to do to him. The kinkiest thing they had ever done together involved a feather and a blindfold, so his thoughts of what might happen next were pretty limited.
When he felt her come onto the bed, her weight shifting the mattress, he was anticipatory, to say the least. He was helpless and out of control and excited by the thought of anything goes, to use the words of the illustrious Cole Porter.
He did not, in a million years, expect to feel a cock pressing against his asshole. He thought she might stick a finger up his ass, to mock penetration of some kind but this was a complete and very welcomed surprise. Where did she get this cock? How did she know how to use a strap-on? His mind was whirling, like a dervish but he didn't want to miss a moment of this adventure, so he tried to keep his thoughts to the here and now.
"You want to feel this cock up your ass, do you?" she asked as her body spread itself over his. "You want to be penetrated like a woman? Fucked? You want to know what it feels like to have something come in to your holes? This I can do for you and happily."
She lifted herself off of him, leaving him suddenly feeling insecure and cold. He couldn't imagine what he must look like, in her nightie, thigh-highs and panties. What she must think, it was almost too much to bear, so he tried to shut down his mind and just go with it.
"We should start by lubing you up, making sure you are wet and wide enough to take my cock. After all, that is what you do for me." The cold lubricant hit the crack of his ass, torturously slow. She was enjoying this, taking control, drawing out the good parts, making him wait, patiently. One long squirt from the pump top began to drip down his crack, then another, and another. He'd never felt anything so exciting as the liquid running down his asshole - until she began to rub the cold gel against his ass. His hips reacted, instinctively, as his ass pushed up to meet her hand.
