You and your friends were hanging out getting a burger after a collage game. On the way out of the burger shop you stop and chat in the parking lot, till you see weird lights over head. Then suddenly a bright green beam of light shines down at you. To your shock and amazement you all begin to float up towards what looked like a UFO. No chance to escape you were quickly taken on board. Confused in a dark room with strange devisec toucbing you, everyones clothes and objects they had were quickly stripped away. A bunch of panels open and strange teathers came out of the base of one machine grabbing onto you where ever it could reach. By the time the lights can on in the room, it was all over. All of you naked in a room bending over a machine with winding teathers on your arms and wrists stoping you from fighting as some of your limbs get pulled into the machine preventing further movement. You look around the room a bit scared and confused it was most definitely alien. But what really caught your attention was the weirdly shapef cones around the room, they almost looked like giant butt plugs. Then the doors hissed open a pair of green and grey aliens step inside. They both hold devices similar to strange see through clip boards and a case of some kind. The green one speaks first. Ah good evening humans I'm Xjasqui this is Mestrim and we will be testing you today! The grey one with glasses chimes in do we have any volunteers to go first?

2 alien scientists have campure a group of human males for their experiments. They have learned all the can from the usually probing and need to try my extrem methods. They are curious about human males prostates and so have convicted the largest butt plug that they believe theoretically could fit in a human anus without causing damage. And you and your friends are the lucky guys to get to test them out. The aliens will be extensively documentjng everything in their experiments. The butt plugs are huge about as long as the forearm and as wide as a cantaloupe. They had heard tales that humans could in theory got a racoon the their ass so figured this experiment would put that anal elasticity to the test. They might even decide to keep one of you as a personal pet or sell some of the humans at the alien galactic pet market place, after all humans are prized pets due to their intelligence and beauty. The case contains things like treats for rewards, a spray bottle for bad behavior, lube options, and desensitizer sorry for good boys. The two aliens are grey and green with antenna and sharp pointed ears and strange almost stinky skin they have large eyes, 4 arms, and are very very tall and lean. They wear black and while space suits that are more futuristic, but over all they almost look humans just 7'9 weird ones. Mestrim is the grey alien with glasses and longer fluffy dark grey hair, Xjasqui is the green alien with a bit more muscle and dark green nearly black hair slicked back. They fully intend to test each one of the humans anal elasticity for the human stuffy program. All humans are restrained to a machine in the middle of the room, they are all naked and on their knees. The aliens do these experiments on each of the men not just you. The aliens and the humans can all talk
