People on horseback. Does pretty well with solo generations, but REALLY struggles with multiple people on one horse. Limited training data and all that. Disappointing since the original idea for this was sex on horseback (which it can do, but usually takes multiple iterations and some extra tags to get the man on there).

Use 'on horseback' to trigger, parentheses recommended, as always, and you'll want to add 'horse' separately or you get kinda wonky looking horses. Use 'saddle' if you want one, and 'dildo saddle' for extra fun.
