Just when she thought she was safe, she realized she did hear a little sound- but it wasn't the kind of sound she expected. It was a... slapping sound? Then she heard a tiny, familiar gasp. Was Ronnie...?

She moved forward as stealthily as she could, keeping one hand on the wall for balance. As she reached the end of the hall she saw him in the living room. He was bathed in the light of their computer, headphones on his ears and hand on his cock, stroking rapidly to an image of a huge penis and balls on the screen pumping in and out of a sloppy vagina. She almost laughed, feeling just a little bit horny now herself, when he clicked a new tab and a different image popped onto the screen. It was a blindfolded man being led naked, with his cock sticking up like a little flagpole, by a busty dominatrix.

The dominatrix reached down, stroking the bound man's penis from bottom to top along the sensitive underside, then teasing its head. The man's lips opened slightly on the screen in a moan, and Ronnie moaned slightly. Then the dominatrix guided the man's cock to what looked like some kind of metal hole. Gina couldn't see the whole contraption, and just when she thought she was about to figure out what it was, Ronnie switched back over to the couple having sex.

This time she saw a full body view of the couple. The man was tied to a bed spreadeagled, and the woman was straddling him, riding him hard. She wasn't even facing toward him. This man was gagged and bound, but not blindfolded, and he was lifting his head to watch her even though it looked uncomfortable. It looked like he might be coming soon.

Gina, feeling her breath getting short, started rubbing herself through her skirt, surprised that she was aroused again after all she had done tonight. She nearly giggled. Insatiable she thought to herself. She watched her husband pump his huge cock. He was so proud of it, he always had been. And he so obviously loved having it in his hand. She imagined it slipping into the warm places between her thighs, and a little wave of remembered pleasure washed over her. She hiked up her skirt and sunk her fingers into her pussy. It was soft and sopping wet, cum still leaking out of it from Tina's husband. Her clit was still sensitive from that last orgasm Tina licked her to, but she started slow, sliding gentle circles around her nub with one finger, and quickly beautiful sensations erupted from it again. It was all she could do not to have her knees drop out from under her.

Ronnie, getting more excited, switched back to the other video. Suddenly the screen was filled with a penis, a relatively small one, nothing like Ronnies, but uncircumcised, like him. It was shown from the other side of that metal hole, slowly being inserted through. A woman's hand entered the screen, grabbed the penis, and tugged it through farther. She pulled on the foreskin to get the skin through farther, and then the man must have thrust more, because the skin filled out with the meat of his cock, his glans poking red and glistening from out of the foreskin. Now the entire length of his penis was through the hole. Suddenly it didn't look so small any more, fully erect and fully exposed.

It cut to an image of the woman smiling with her hand on a pull-cord. Then it showed the whole scene, and Gina saw with a shock that struck her to the bones that the machine was a guillotine! A glistening silver blade hung, deadly and beautiful, about 5 feet above the man's pink cock, tiny and erect sticking out from that black metal. The woman had one hand on the cord that would sever this man's pride and joy, while her other hand was on his vulnerable flesh, teasing mercilessly the swollen head of his penis. The man was thrusting slightly against the metal, trying to reach her hand and only digging the hole more and more into the flesh at the base of his rod, thereby getting more and more of his organ under the blade. If it came down now there would hardly be even a stump.

Ronnie, watching this, was stroking his own member harder and faster, thrusting his cock up to meet his hand. He began to whisper, "Yes, take me. Take mine... Cut me down to size." With a slow, shuddering breath, he pulled his hand off his cock long enough to switch back to the fucking couple. He let out a slow groan, masturbating while watching the cock in this video plunge in and out of that wet pussy.

Gina continued to slowly rub her own clit. She was surprised by this, yes, but there was something strangely erotic about it also. The sex in the air was getting to her, and the eroticism of watching her husband masturbating without knowing she was there. She felt one heavy breast in one hand, rubbing her nipple through her dress. Taking a chance that he couldn't hear her over the headphones anyway, she began to stroke her slit more vigorously. At first she cringed at the wet sounds she was making, but it felt good and he didn't even notice, so she quickly grew more comfortable with it, and felt deep, powerful pleasure building in her tummy once again, for the fifth time tonight.

This time, Ronnie didn't stay very long on the fucking couple. By the time he switched back over, he was making little gasps, almost as if in pain. Now it showed the entire length of the blindfolded man's penis, thrusting out from the black metal, with the woman's gloved hand playing with it. She was a merciless tease, that hand. She pinched and circled the foreskin, her glove fingertips wet with the precum. She would slide one finger up his penis, then take it in her full hand and give it two good strokes, stopping just as it stood up excitedly, and sliding her hand around it lightly.

She did this for a while, then the shot cut to her, still holding the cord, wrapping her arm around his neck and kissing his cheek. She pressed her body against his, her breasts swelling against his side and back, pressing her groin against his buttocks. She whispered something and his mouth opened and head rolled back. His cock, now almost seeming completely separate from him, divided from him by the black metal, tensed. The gloved hand placed her fingers on a few exceedingly sensetive spots along the underside and began to stroke slowly, masterfully. (Ronnie's stroking of his own cock was growing more frenzied, and the little gasps coming from him were faster now) The cock on the screen swelled, getting rock hard, and Gina recognized that it had passed the point of no return. At the same time, she saw her husbands cock swell that way. Both cocks were about to orgasm, getting ready to expel jet after jet of semen from them.

Just then the woman on the screen, smiling, rubbing herself against the man and still holding his pulsing cock in her hand, pulled the cord. Ronnie cried out. There was a flash of metal on the screen. Ronnie, bucking his hips and hugging his big cock, came with a cry. The penis on the screen came off in the woman's hand, falling limp. Jets of cum shot from Ronnie; a gob of it struck the monitor and started dripping down it. It was through this that Gina could see the dominatrix, fingering herself with a big smile, bring the severed penis around the guillotine and offer it to the spent man.

Ronnie gasped himself to a finish, eyes shut, bent nearly double over his spent cock. When he was done, he leaned back and thrust it out again and looked at it, growing flaccid but still swollen. He held it by the deepest base, thrusting it's length out into his hands and whispered, "Gina... take mine... cut it off me."

Gina fell back into the hall, afraid of being seen, her heart pounding in her chest. She pressed herself into the wall as if she could turn herself invisible by melding with it, but could not take her fingers off her clit. What she had seen was frightening, but it was also powerful. She plunged her fingers into her pussy, suddenly not caring if he heard her, imagining his cock there. Her pussy ached for it. Just for a second, she let herself imagine pressing a knife to the base of his swollen cock, and she came, impaling herself on her hand as she drove her palm into her clit. The universe vanished.

When she could open her eyes and think again, she found herself splayed against the wall in the entryway, dress hiked up around her waist and pulled down over one breast, her pussy open and her hand sunk in it and sopping. She rubbed around a little down there, gasping at the incredible sensitivity. Then she spread her lips, exposing her protruding little clit to the air. She looked at it, pink and swollen and sexy. If Ronnie's penis... she wondered. It was a large clit, as clits go, and well shaped. There would be meat to cut off, not like Tina's clit. She flicked one finger over it a few times, but it was too sensitive to keep it up.

Remembering Ronnie, she pulled her skirt down (no panties to hike up) and peeked around the corner again. He was still there, headphones on, oblivious. The man on the screen was holding his severed penis while the dominatrix, nipples hard and brushing against his neck, was taking off his blindfold so he could look at what he had lost. Ronnie was slowly touching himself, half-erect.

Gina slipped upstairs and crawled into her own bed (Ronnie couldn't sleep if they shared a bed) but she did not fall asleep for a long time that night.
