Forty minutes later you had me strapped into place over a spanking bench. My ass was on full display while my knees and stomach were supported. My head was tied in place, and the rest of your colleagues entered and stripped. At first they all meticulously noted the sizes and characteristics of their new cocks. You had previously had a tight, plump camel toe pussy and now you had a thick, girthy cock to match. Jessica’s cock had a healthy amount of foreskin that puckered at the tip and she documented that she had long labia before the virus had taken root in her. Ashley had a long, skinny cock and she said her vagina had protruded from beneath her legs instead of staying tucked inside of it. I was ignored during all this scientific small talk, but once it was finished, you spoke up.
“What should we test for? How many times in a row we can cum? Volume of cum? If and when our libido abates?”
Jessica and Ashley said that seemed like a good place to begin and that everyone should observe for any pertinent occurrences. That’s when the craziness really started. Ashley took be from behind, sliding her cock into my sore asshole that forced a moan out of me. Jessica slid her cock into my mouth, stifling my moans, and I sucked on the tip of her, enjoying the feeling of rolling her foreskin in between my lips. She stiffened at my treatment and impatiently grabbed my head and began to fuck my throat. It took all I could to just breathe with her blocking my airways. I could sense her balls jiggling and bouncing as she thrust away into my mouth. She kept up the speed for awhile, not ever pushing her cock all the way down my throat. I was grateful for the courtesy because I’m sure I would have suffocated on it. It was not long before I could see her hips began to buck in a rhythm slightly more spastic and less rhythmic. Her cock exploded in my mouth, shooting enough to fill my mouth ten times over. Unable to swallow even a quarter of it, semen sprayed from the sides of my mouth and even from my nose as Jessica’s firehose of a cock unleashed in me.
During this Ashley had been mercilessly taking my ass as she liked, thrusting so hard and deep that I could feel her balls pressing against my taint with each thrust. She held my waist in her hands and pound out a frantic rhythm that I doubted anyone could match. This enhanced speed must have been another side effect of the virus they had all contracted. Because of the sheer size of her cock and speed of her fucking me, my own orgasms began to occur in a steady rolling rhythm where my own cum would pour freely. The orgasms racked my body with an intensity that was unmatched. Each orgasmic wave that hit me lasted so long that the orgasm itself seemed to be eager itself to be permanent. Minutes stretched on while my body jerked and flailed against my restraints, my toes curling and flexing in ecstasy. Ashley blew a load in my ass, pushing me over the edge again, and then Jessica took her turn filling me while my girlfriend, Sarah, fucked my mouth. This rotation went on like this for hours. The girl taking a rest would count their orgasms and calculate the volume of each cumsplosion. So far they all seemed to be around half a gallon per cumshot and their cocks never seemed to soften or tire. My body did, however. My brain could only handle so much dopamine being dumped into my brain, and as a defensive mechanism I fell into an orgasmic coma for the rest of the night. When I came too and the sun was still shining through the windows, I was not sure if it was the next day or the next week. The floor looked as if there had been a blizzard. The amount of cum that had collected on the floor was beyond comprehension. As I was unstrapped from my bondage I was overtaken by an electric jolt that shot through my entire body. I knew that these were the aftershocks of the seismic orgasms that had been rent through my body.
“We’re amazed at how well you held up to the challenge of aiding our tests,” my girlfriend said as she held tight to her chest and kissed me on the lips. “I never knew you’d enjoy it so much.”
