Having looked through the timeline, I think the party was quite successful and fun for all of them, except for the last hour. The ground rules were set and worked well, M&M M&H swapping and I&K doing their own thing. I don’t believe that Kostja acted as a pimp, he could not perform and wanted Indira to experience the same as Mira and Marica were getting, so asked Henry to help out. Yes, he could have moved round to hold and kiss Indira but decided to leave the room, however Henry only fucked Indira for less than 3 minutes before she asked him to stop. All evening I&K were very loved up and constantly kissing and touching each other, so I think the rules worked for them. She also kept her panties on most of the night until round 2 started, at which Kostja performed quite well fucking Indira for 5 minutes, but still trying to watch what M&H were doing rather than concentrating on Indira. BTW Mikl also had limp dick problems at the time, and he and Marica left the room.
Unfortunately I believe something happened in the kitchen when they were making food, Indira left and took her food to the lounge where she sat on her own looking very unhappy, and even when Kostja came in she was frosty towards him. The cameras in the kitchen had people blocking them, so could not see Indira’s reaction to what may have caused the issue. So it looks like Kostja managed to snatch defeat from the jaws of victory in the last hour, and then suffered the wrath of Indira in the loggia.
Hopefully the situation was repaired when they arrived home.
