Tied to the bed naked, spread eagle and blindfolded, his cock sprang to full attention when he heard the bedroom door close. Where in the room was she? Just knowing that she had him completely helpless and on display for whatever devilment came to her mind made him shiver.
It had been a good hour since she stripped him and tied him there then walked out leaving the bedroom door wide open. The sounds of her girlfriend's monthly gathering downstairs had drifted to his ears and successfully masked any footsteps of traffic in the hall. He wondered if any had used the bathroom, walked past that door, and saw his helplessness. He knew all the women from her little group - now he would have to wonder what they knew of his "kink." That thought alone had kept him partially aroused for the entire hour of waiting for her return.
A soft rustle of clothing near his left side made him refocus on hearing where she was in the room. Something soft and wispy touched his balls making him startle. Then he felt the lightest of caresses run up the throbbing, sensitive shaft of his cock. Over and over the stroke teased him. Without realizing it, his hips lifted off the bed in a vain attempt to feel what ever it was better. Then a different sound caught his ear. Ice in a glass made a little sound of settling as it melted. It must be on the nightstand he decided.
Then, during one of his involuntary hip thrusts up off the bed, he felt what would be the first of a series of wet, cold invasions to his anus. She was pressing an ice cube against his brown pucker... silently, insistently, without yielding to his natural reaction to clench she gently forced the slightly melted cube, finger-deep into his shocked ass.
Meanwhile, a soft hand wrapped fingers around his cock and slide slowly up and down with a slight rounding motion. In spite of his desire to press his ass down onto the bed and prevent any further icy assaults, his body rose to the pleasure of being so expertly stroked. As he did, another ice cube worked its way into him.
Over and over the pleasure of that hand on his cock coaxed his body to expose his ass which was immediately given a cold, wet kiss of ice. After what felt to him like an entire tray had been pushed into him for melting, he felt a new sensation.. smooth and slippery, a long thin object began to follow the ice. He couldn't believe she was pushing a dildo into him!
Now, with the end of the dildo protruding from his ass, he could no longer comfortably rest his ass on the bed without driving it deeper... so of course the stroking suddenly quit. He heard nothing. All he knew was feeling incredibly full behind, and incredibly close to an orgasm.
Suddenly, with a sharp whistling sound something that felt like a handful of small cords lashed across his throbbing cock and balls. He instinctively jerked down, away from the sting only to impale himself on the dildo a bit more. His ass clenched around it, try to resist its progress inward, but the lubed toy was unstoppable.
Repeatedly, he felt his cock lashed and stung. Repeatedly he involuntarily fucked his own ass on the dildo. The stinging sensation at first dulled his need for release but gradually he came to a place where he found that his body pushed up in anticipation of the next lash. He didn't have a fully conscious thought about it, but he realized that his movements on the bed and predicament had been carefully orchestrated to make him try to fuck the painful lash while also fucking his own ass.
A moan escaped him as he writhed at the need to cum. As if that moan were a signal, the lashing stopped.
