Roy Alexandre's Boobcage series immortalized huge fake mammaries, and this earlier feature achieves similar results.
Lesser-known Sofia Staks is perfection in the race to bigness, of a level with Minka, and she fills out a fetish black brassiere for Peter North with predictably heavy load results.
Biggest star here is Heather Lee, delightful in poolside sex with North. Brittany O'Neil's tan lines and trim figure (underneath those jugs) are a plus.
