The latest volume in their ongoing salute to Nature’s wonders, Ambassador’s Big Bust Babes, Vol. IV is subtitled “The Bigger The Better,” a claim that would be somewhat hard to prove by this tape. Vignettes of how such outstanding females as Nikki King, Ebony Ayes and Trinity Loren use their “attributes” to get what they want out of men are centered around a frustratingly “flat-chested” Nikki Randall’s attempts to prove to guys that small breasts can be fun, also. Considering the big talents employed here, it’s  a shame that most appear only once on the tape.
