Wow, this is a wonderful animation! The girl-on-girl movement is near perfect as far as I'm concerned. There are a number of little touches that I appreciate in this animation as well. For example, I really like how the girl is grabbing the sheets with her hands. The way her breasts subtly press in the bed is really nice too. The way you draw the female form is just wonderful: curvy in all the right places without going overboard.
Fantastic animation! This is probably the best TG/BE sequence I've seen. I particularly love the way you animated the breast expansion sequence. WOW!!!
