They're from Ste's Country Road quest. They were the construction workers you could save. In the most recent patreon release along with the fun stuff you can do with Korg and Ste you can get the gloryhole scenes at night at Ste's farm. The new gloryhole scenes are currently only available in the Bottom Logan route. The wording in the update notes makes me think it'll show up on the normal Logan route in a future update
