Glad you liked it;)
I have to assume you're referring to Mila Stream #2, since she doesn't really do anything in that one. I try not to bloat the gallery with random teasing scenes, but when it comes to the streams I just include them either way as a sort of internal rule I have. (I make an exception for the first one because I made this rule while I was making 0.3, and lets be honest, nobody is gonna replay the very first stream.)
I usually don't include simple tease scenes outside of that unless they're a smaller part of a larger scene, like with including each Dareline round as a seperate scene, which was done pretty much in case someone wanted to replay a specific part of that admittedly quite long scene.
Tease scenes like that are not the norm though. I'll include all the streams in the gallery regardless of length, but the vast majority of sex scenes will be of the length people have come to expect from me. I think it's fair to treat the "A night with Aida" scene as a general average, with it maybe sitting on the longer end of what I'm aiming for for most of the important scenes, but not necessarily the longest I'll make. Some scenes need to be long as fuck for the sake of selling what I'm selling.
I'll do the occasional short one, but if you encounter one of those in an update, it usually means there's a longer one coming.
