Youthful Lust (1973)

The blonde is on her knees first, sucking the guy with that slow, deep throat action — you can see her jaw working as he holds her hair. She’s slim, long-haired, probably early 20s, and takes it like she’s used to being the starter girl. Then the brunette slides in — darker, shorter cut, same slim build — and rides him hard in front of the fireplace, bouncing in that bouncy college girl way. Camera stays close during the creampie finish, white all over her belly and his dick. Lighting’s dim but clean, not grainy, gives it that intimate living room vibe without looking amateur. The guy doesn’t do much besides lie back and moan, which is fine — this is clearly about the girls leading the show.
