Gloria was heading back to her room when she passed another open window with sounds emanating from it. Despite being just a fly, she knew what those vibrations meant: some of her neighbors were getting it on!
Realizing that she had the opportunity to finally be a 'fly on the wall' Gloria buzzed through the open window and landed on a lamp shade. Sure enough, there was a couple of 30-something humans on the bed, engaging in intercourse. Gloria thought back to her previous day's mating and began to miss it. How strange her life had become; now the sight of humans having sex simply made her long for sex with a bug! She really was used to being a fly now.
Turning her attention back to the bed, Gloria was confused why these humans hadn't taken advantage of a transformation yet. That was the entire point of the resort, after all. But maybe they are new arrivals who just couldn't wait to jump each other?
But then Gloria began to listen to their conversation.
"Oh!" exclaimed the man. "I can't believe how warm you are inside! And I'm just so... so... So big!" The man's eyes were locked on his penis as it slid in and out of his companion.
The woman just giggled and stared at her own breasts as she pinched her nipples. She also grabbed one breast and shook it wildly, laughing at how it jiggled.
And, suddenly, Gloria understood. She was watching a couple who had swapped their genders! She sat awhile longer and listened to them express amazement at their new bodies. "You are so deep inside me!" "I never knew that getting hard felt so good." "I never knew that making someone hard would make me so proud!"
Although she was enjoying her time as a fly, it suddenly made Gloria wonder if she was missing out by not trying a gender swap. Just what would an erection feel like? It wasn't too late to find out. But being a voyeur was a lot of fun too!
