I thought Lucas only fucked Tanya & Pixy. I thought it was Leo who fucked the guest girl at his place.
No, from Amelie & Lucas first place (way before Bella&Leo), Lucas had a guest girl there just for himself but his dick didn’t want to collaborate even with his tries 
true … but i think there was a pre-history involved… and as far as i can see… most of the time regarding sex, it depends on Amelie to give consent… if she feels uncomforable, then it does not happen…
reality is that Lucas and Amelie are the only ones that realy can answer these questions, but i think they will just leave it hanging in the air…which creates mystery, and keep us watching…
as i said… this is how i see their interactions… i could be totally wrong…
Idk I think tinder may have been involved. 
The threesomes they had with Castro seemed very manufactured to get views. During one of the threesomes, they kept moving back and forth between the free cams in the living room and the bedroom over and over again in order to get their views up.
when one of the people involved is uncomfartable with anything or anyone… then it should sure not happen
You are not.
Strict rules are in place between them. And because they stick to them, things work, albeit too slowly for many here. I personally appreciate that, especially from Lucas. It takes character to have a Pixie in front of you and not try anything outside the rules. And Lucas has a lot of it.
For me personally, the realm with the least or zero negative shocks and drama (in a war times!) , they develop their relationship in an sexuality open mode very organically.
Yes, Amelie is the one who sets the pace and Lucas is the one who allows her to slowly open up her sexual potential.
And I love it every second.
But Pixie had sex with Lucas few times during their threesomes
Only two times if i’m correct… and after that they had several sessions without
But above of all, let’s not forget they live in a country which is at war… it would make absolute sense to me that they have more important issues on their head… i can’t imagine how it must be for Amelie when Lucas goes out with his gun or for Lucas wandering outside when there is a war going on around him…
Let;s hope they stay safe and there will come a better time soon…
3 times I have seen live…but might be more…its true that most of the times dont… I think, after first time, Amelie and Lucas had an argue (not sure if regarding this as I don`t understand the language).
Sad that not all of them were saved in the archive
havent seen them all, was in a period that i was pretty busy irl… still this was the only apartment i tried to keep track on… and i know what you mean about the archive… to many times i think this will be saved and doesnt show up… i quess we need to use to archive request form more
