a couple fun suggestions id like to see added are
Multi catch and have multiple girls in the same locker for a gangbang
multiple angles maybe one that looks alot like the forward facing angles in tentacle locker 1 would be a neat inclusion
there could also be a clothes toggle so you can decide if you want the girls fully naked or just the way it is now while your in the locker
(just a personal thing but please more scenes like the bathroom one flat chests are hot)
