Dans la chaleur de St-Tropez (1981)

Marilyn Jess and her friend Mika Barthel go on vacation to St. Tropez. The two friends meet a troupe that is shooting a porn movie and do what any couple of friends would do on holiday: they join the cast. The cast includes Cathy Ménard and Olinka Hardiman, who suck and fuck without brakes.
The four actresses give us several breathtaking sequences. The film begins with Cathy Ménard buried up to her neck on the beach. There’s only the head, but Cathy takes full advantage of it, first licking Olinka between her legs, then giving a blowjob.
Marilyn Jess in this film is even more beautiful than usual and is exciting in all the sequences, from the lesbian with Mika Barthel to the threesomes.
