Cuatro mujeres y un lío (1985)
The guy in a suit starts off holding a salami, looking confused. Next thing you know, he’s making moves on three brunettes and a curvy redhead in a white blouse. Two of the girls are sitting on the bed, one in a negligee and the other in a white dress, teasing him. The action moves fast — kissing, flirting, and then full-on group sex. The redhead takes charge at one point, riding him while the others watch and join in. The camera work is solid, with good angles on the oral parts and close-ups during the doggy style action.
