Fango bollente (1975)

One of the women is brunette, slim, with small tits and a tight ass — she’s the one getting pounded from behind on a slick surface after they both strip down. The other girl’s got a thicker build, big natural tits, and dark roots showing under her dirty blonde dye. They start off rubbing mud all over each other’s bodies, not much actual sex at first, just full-body sliding and teasing. Doggy style comes next, the brunette on her knees while the other one grips her hips hard, fucking her deep with long, steady strokes. After that, the thicker girl climbs on top and grinds down in a reverse cowgirl position, then leans forward for some sloppy kissing. Camera stays close during the penetration shots, gets good angles on the ass and pussy when they’re bent over. The mud makes everything look slippery and messy, adds to the filth factor without being overdone.
