CLOCKTOWER RESEARCH LABORATORIES RESEARCH LOG

Earth Pony Breaking Endurance Experiment, Test Run 03

Objective: Run a full test to completion.

Experiment Milestone: Last two tests failed due to equipment failure attributed to unforeseen mechanical stress on the restraints. We have at least affirmed that earth pony sexual endurance outlasts the endurance of our laboratory testing benches in long term testing. Our latest breeding bench model only lasted until orgasm no.42 before exploding violently during test run 02. Our materials laboratory have designed a new restraint system using arcanoplasteel-adamantite composite which we plan to use during testing today. With luck we should be able to simultaneously gather data on the new material. Unfortunately due to time constraints, the materials lab only managed to fashion a pair of hoof cuffs. If today’s tests go well, we can begin mass-producing these new restraint systems to allow earth ponies to take part in the new endurance competition fad sweeping across the Society.

Volunteers: Master Big Macintosh, Mistress Cheerilee and Mistress Marble Pie (Acting as a Switch Submissive for the purposes of this experiment, slave registry no. MBLP-01221). We brought back the volunteers from the last two tests to minimize variables in our experiments.

————————————————————————————————————————————————————————

The test subject could only whimper softly as she squirmed against the restraints pinning her forehooves behind her back. All she accomplished was flop helplessly on the cool floor of the testing chamber. Her flank still stung faintly from where the researchers had labelled her ‘Endurance Test 03 Subject 01221′ along with her barcode like the lab rat she was. She had scarce little clues as to what the scientists planned for her that day. The only other hint was the large orgasm counter on the wall with enough space for triple digits.

She could just about make out the shadows of ponies moving about beyond the viewing glass, all of them no doubt watching her like fish in an aquarium. Soon they would begin gathering data as her helpless little body was cruelly experimented on.

She couldn’t help but shiver with a mix of fear and excitement at the thought.

They scientists certainly hadn’t spared any expenses for this experiment. She was normally very good at recognizing materials, in fact it was one of her many talents. However she could not for the life of her identify the material the restraints were made of. Furthermore, the testing equipment arrayed on a clinical tray next to her were state-of-the-art stuff that not even the low level scientists were privy to.

She felt herself begin to moisten the floor she lay against as she helplessly pondered her fate, the toys promising an eternity of pleasure and pain as she was experimented on mercilessly. She was just beginning to writhe against her restraints with impatience when her tormenters trotted in — a stallion and a mare. They both smirked down at her as they circled her, inspecting the test subject they were about to toy with.

The stallion’s easy grin only widened as he picked up a toy from the clinical tray. The test subject craned her neck to try and get a glimpse of her soon-to-be instrument of enslavement. She could only gulp as she recognized it as one of the new experimental anal-spreader rings designed to sit inside her tailhole, beyond her sphincter. It was designed to self lubricate, supplied by a thin tube leading out of her anus that also acted as its retrieval device. The auto-lubrication would allow her tailhole’s user easier and deeper penetration. However its position deep beyond the opening of her ponut meant it did nothing to reduce the tightness of her puckered ring, allowing her user maximum pleasurable snugness as he penetrated her and maximum pain for her.

“Present yerself, slave,” her Master growled with barely-concealed relish. She obediently complied, raising her tush into the air, knowing that resisting would only prolong her suffering at their merciless hooves. She gave a squeaky little whimper, trembling as she felt him pull her ample flanks apart, revealing her tight puckered little ponut. She risked a glance back at the stallion. She gasped a little at the sight of his stallionhood. Even at half-mast it was a behemoth that more than dwarfed her little tailhole, promising to stretch her to breaking point. At full erection it would probably destroy her.

Her ruminations on her fate were rudely interrupted by her ponut being stretched mercilessly apart. “MmmmmmMMMMHHHN!” She cried as what was undoubtedly a whole hoof pushed down against her puckered star. Her tight ring could only give way under the sheer force, allowing the massive intruder to stretch her apart. “MmmmmMMMnnnnNNN! MMmmmmMMHHHMMM!” She could only squirm and wriggle helplessly around the hoof sinking into her like a puppeteer donning a sock puppet. Her puppeteer mercilessly twisted the hoof inside her as he pumped her slowly, deploying what felt like the anal spreader ring deep inside her.

“Now Ah reckon you’ll love this new feature on this toy.” She heard her Master chuckle darkly behind her.
“MMMMMMMMMNNNAAAAAAHHH!” She cried as a shock ran out of the anal spreader ring, forcing every muscle in her tailhole to contract painfully around the intruding hoof.

“Hmmm, Ah’m gonna love feeling ya clench all tight like that around mah cock when Ah shove it in ballsdeep in ya.” The stallion commented idly as he finally mercifully pulled his hoof out of her. Her poor abused ponut quickly closed back up, twitching helplessly at the brief respite.

She was still blinking the tears out of her eyes when she felt something brush against her lips. “Drink, slave.” She glanced up at the bottle of clear fluid being pushed into her lips by the mare. ‘Clocktower Research Laboratories Marecum-based lubricant’ it read. The mare squeezed the bottle, forcefeeding the cold soursweet lube into her mouth, working it into her tongue while her hoof massaged her throat, forcing her to swallow the lube into her throat, coating her walls with it like the cock sleeve she was.

As the bottle was finally emptied and removed, the poor test subject caught a glimpse of the mare’s nethers. Her eyes widened as she realized she was one of those herms, one hung just as big and heavy as the stallion no less. Her heart sank as she realized she was about to be mauled and destroyed in both ends.

The Orgasm counter on the wall finally turned on, its counter set at zero, zero, zero….
