No, but I'll be around.

"No, it's your moment. But I'll be right here if you need me!"

Need you? Yeah, to clean, maybe.

"Okay, John! Thank you!"

You stayed in the living room as Amy excitedly closed the door behind Monica.

You sighed and covered your face with your hands. What had you done? You had accepted this —honestly hot — futa girl to fuck your girlfriend. And she was definitely big! How would Amy manage? How would things be after that? You felt stupid, disappointed in yourself, and... Aroused?

The idea of your girlfriend being taken by an athletic futa girl made you really, really horny somehow. You paced around your living room a couple of times, with an erection bulging under your pants. Then you took a chair and sat right next to the door to the bedroom.

You could hear them giggling and kissing. You recognized Amy's moaning when she's caressed in the right places. Then, clothes coming off.

"Oh my god, you're much bigger up close!" You heard Amy say.

"And it's all for you, babe." Monica replied.

Then, you heard more moaning, and slurping, and muffled breathing. You could picture your girlfriend sucking on some huge dick coming from that girl's crotch. You weren't thinking when you unzipped your pants and took out your own cock.

"Oh, you were really hungry, babe."

"Mm-huh" There were giggling.

"Right there. Really lubed up now. Ready babe?"

"Yes. Go slowly, please. It's so big."

"Everything for my babe."
