Can someone suggest movies where some kind of competition is going on. Couples switching partners and women need to make ''other team'' males cum and men need to hold as long as possible so they wouldnt loose.
Rocket is chock full of these movies. [RCT-810], [RCT-890] are two recent ones. Most are 'family' related, though.
Also, Apache has a few, as Supmop suggested. [AP-011] is one I've seen that I remember being good.
DVDES has a series that is sort of game-like - stepmom, dad and stepson are brought in, dad's put behind a 2-way mirror, and stepmom and son are given a list of challenges, that, should they complete, they get prize money. There are other combinations involving sisters, college students, co-workers, etc. [DVDMS-010] is the one that sticks out in my mind.
