Susana and Tim were glory hole addicts. Some evenings and most weekends they would visit the best book stores and Susana would get-off on watching Tim having his cock sucked through the hole or servicing a cock pushed through to him. Best for Susana was if the other guy was bi and with his partner. Often, when it was over, she would kiss the other girl through the glory hole, sometimes with their partner's cum still around the lip of the hole.

Then they started to hear the rumours. Rumours that there was a couple out there who liked more, much more. Now it began that when Tim had his cock through the hole, Susana would tease him that the special couple were the other side. Susana had to leave it until sometime into the suck because as soon as she mentioned it Tim would get extra turned on and cum quickly, flooding the mouth of the guy on the other side.

If Tim and Susana looked through the hole and saw a couple they would get so excited, wondering if these were the ones and Susana always wondered if the other couple were thinking the same of them, it made for an electric atmosphere.

Unbelievably, now it had happened. Tim had looked through the hole and Susana had seen him stiffen, literally in both senses and call her over. As she crouched there now, Susana saw the strong woman with the knife and the husband with a smooth patch where his cock had been.

It was such an erotic moment, without a word between them, Tim fed his hard erection into the hole, Susana could have died with the thrill of it. She noted that Tim looked a little pale and was taking short breaths but the way his buttocks clenched and he was forcing every last inch of his cock through the hole, made her satisfied that he still wanted it.

Susana couldn't see what was going on but Tim tipped his head back in ecstacy, so she knew the husband had started to suck. With that a hatch opened at head height and there she was, that powerful woman Susana had fantasised about so much. Susana was apprehensive but she stepped forwards and their lips clashed in a passionate kiss. After maybe a minute, the woman stepped back slightly and peering through the hatch to her left, Susana could see the husband sucking Tim's cock. By positioning herself at the right angle, Susana could see her husband's clenching buttocks in her stall and his hard cock being sucked deep, in the other.

Susana's concentration was broken by the woman passing a sturdy leather strap through the hatch. Susana took it and it was obvious where to secure it (on sturdy hooks either side of Tim) and she tightened the buckle so the strap dug hard into her husband's buttocks and he couldn't pull away from the hole.

Susana returned to the hatch and took in a sharp breath. The woman was standing by her husband now, knife in hand and an electrical quaterizing devise in the other, it wouldn't be long.

It happened quickly but seemed to last a life time. Susana was aware of Tim tensing. The husband pulled his hands back from Tim's cock and Susana saw it twitching. As it did, she saw a look of pure evil and delight cross the woman's face. She stepped into her husband, pushing him away and grabbing the cum spewing cock that came out of his mouth. Pulling the cock out from Tim's body hard, she took the knife and with a few saws of the blade cut Tim's hard cock off. Out of the corner of her eye, Susana had seen her husband's head fall back in ecstacy but now his teeth bared, like a horse pulling back its gums, and he let out the most incredible scream of pain, shock and horror. Susana saw a spurt of cum shoot from the area where her husband's cock had been as dropping it to the floor, the woman grabbed the handle of the quaterizer and held the hot rod to the area, as Tim screamed again. Susana didn't hear his second scream as she was lost in the biggest orgasm of her life.
