Two of the above mentioned scenes are still on eroprofile in my albums:

(girl at 40:45 min, who barely gets her panties down in time

(girl at 55:13 min, which is also my favourite - not such a close call, but I love her bouncing around, her facial expression, her sighs of relief...)
The last one I would have loved to see arriving at a toilet 15-20 minutes later!!
