for the gas, I prefer genuine gas but can understand not something easily done on command, I have a huge library of genuine rips in that scenario that can be dubbed in vs using stock sounds, so you can just roleplay it and i'll throw them in. There should be a scene where you sit down in the leggings, then pull them down to show off the pink thong. Kind of what you did with the last one. One other thing try to have the chair/frame more centered like seen in sample shot. :)
