I had an animation suggestion/request, if you feel it is something you could do...it is similar body positioning at Mithos's, but not the same type of animation.
This also could be done in a aggressive (rape) style, if you wanted.
So the female is on her back, with a slightly elavated bum and the male is on his knees.
Stage 1/2 - Females right leg is over the males left shoulder, other leg is on the ground so female body is at a slight angle for this to work for stage 1 and 2. Male could be grabbing/holding the females leg with both hands while slowly thrusting.
Stage 3 - Females other leg is now over the males other shoulder (female no longer needed to be at an slight angle now) and the pace of thrusting increases with the male perhaps holding the hips or each leg of the female now.
Stage 4 - Male is now leaning forward slightly (no longer straight up and down), legs over both shoulders still, pace of the thrusting is faster/deeper as he gets close to climax.
Stage 5 - Same as Stage 5, except the standard slower, deep thrusts as he climaxes
Again this just just an idea, but I like the animations you have done so I wanted to come up with an idea to help,as I have 0 animation skill, lol
