Wifemistress (1977)

The video starts with a threesome involving two slim white girls with short dark hair and a muscular guy. They’re all in their 20s. The girls take turns with the guy, first one giving him a blowjob while the other fucks her, then switching roles. One of the girls has a notably petite frame but surprisingly full breasts. Later, one of the girls appears alone in several solo scenes, walking in a park, standing in a dark hallway, and getting close-up shots. Her dark hair is often messy, adding to the intimate feel. The camera work is solid, especially during the oral scenes, with good angles on the action.
