Spacedock Party (Patreon)

There was always a very lively "intercultural exchange" going on at the large spacedocks orbiting Terra Prime. Crewmembers hailing from everywhere in the galaxy used their free time to really get to know the locals up and close. Of course it was a plus if the anatomical differences were not too extreme. The closer the aliens resembled humanoids the easier the communication and socializing was during these times.  The terrans were surprisingly open to all kinds of experimentation, all social and sexual inhibitions had apparently been shed millenia ago.  A truly advanced species.
