by DragonCobolt on Sep 16, 2017
Sci-Fi & Fantasy

Author's Note: This is a "soft" sequel to Prom Date, and takes place in the same universe as The Lonely Autopilot. Enjoy! All characters are above the age of 18.

Tip Fans in the Diverse Community Making. Modding. Re-creation. Perversion. Tip's fans were doing it their own way with her, just like me. Is it any wonder?

Sci-Fi & Fantasy

The night air was warm on Celeste as she lay atop her sleeping bag and stared into the star-filled sky. Space, the source of inspirational fuel to so many, appeared only bleak before her green eyes. The seemingly endless mystery of twinkling stars fueled only maddeningly irritating questions in her mind. Would we ever know if we were alone in the universe? O...
