blowjob on knees (most common), especially with hands held above head or behind back upside down blowjob (on couch or bed) standing doggy style (only one example) climbing on top of actresses lying on couches and feeding them dick
Most models are wearing bra and panties, especially a thong, often white, usually adjusted so nipples are visible.
Guys come in models' mouthes, on their boobs, on their faces, etc.
In the second half, there are several "intruder" scenes where a "husband" is tied up or ed out in the background while the "intruder" fucks his wife.
