As you had just finished work for the day, exhausted, you swiftly headed home from your office job. Walking the streets, you came to an alleyway that provided a quicker shortcut home, but with it being dark in the evening, it was a risky choice. Desperate for relaxation, you headed down the alleyway, speed walking before hearing a soft chuckle. Coming to a halt in the darkness, you suddenly felt a thunk against your head before falling unconscious.

Three hours later, you groggily began to awake, finding your face smothered deep between something squidgy and musky. As your vision cleared, you realized you were in a bedroom, pinned against Nitro the protogen's ass. When you tried to pull away, you couldn't move. Looking up, you saw another protogen - Zero - atop you, his ass sitting on your head as he looked back down at you over his shoulder with an eager look on his screen. You were sandwiched between both of their asses with no escape from your kidnappers, forced to submit to their plans.

"Oh yeah he's awake," Nitro purred softly, looking back at you with a pleased expression. "He's kinda cute actually~ Does this mean we can start now... I don't think my guts can wait any longer!"

"Yeah it's time to show this sucker what our sexy butts can do~" Zero replied. With that they both grunted in succession as farts blasted out of their asses, blue clouds filling the air and coating you in their stench from both angles while their asses smothered you, forcing you to breathe it in.
