Questo e quello (1983)
The scene starts with a single guy in his 30s hiding behind a curtain, then cuts to a group of people chatting outside. Things get interesting when a 50s guy hooks up with a 30s woman. The camera captures a lot of conversation and some explicit moments. One notable part is when they switch to a mixed group setting. The performers have average to slim builds, with brown or gray hair. The sex acts include conversation, some touching, and possibly oral sex. The outdoor and indoor settings add to the variety.
