There are my suggestions:
#1: (based on Beastars) Legoshi deflowering Juno
#2: (based on Around the World with Willy Fog) Willy and Romy alone in their bedroom totally naked, Willy giving an erotic OTK-spanking to Romy
#3: (based on 2022's Lightyear) The realistic version of Buzz meeting the realistic version of Woody
