English to Hungarian Other General / Conversation / Greetings / Letters Contemporary term

Egy modern amerikai életformát népszerűsítő film képaláírását fordítom, ahol két fiatal nő beszélget séta közben:

Jane: Listen Chas, while I was waiting for Pat last night I saw you at the Green Garden with Bruce... You seemed to be having a very good time.
Chastity: Oh, yapp. We met over the project, but then we went dancing.
Jane: Tell me... Is he your lover, or your sister's boyfriend?
Chastity: Oh, Bruce... He is so cool, and he's gonna marry my sister in May. We are just friends with benefits.
Jane: And how Meaghan [the sister's name] takes it?
Chastity: She said she don't mind,...as long as we are only friends with benefits.
Jane: But you like Bruce a lot. Don't you?
Chastity: No fret. He is awesome. I always enjoy sex with him.
Jane: Good for you, Chas!

Számomra minden világos, csak éppen fogalmam sincs, hogy a mai magyar kultúrában hogyan fejezik ki ezt a "friends with benefits" viszonyt, ami tulajdonképpen barátságot jelent, de a barátok nem szerelmen alapuló nemi kapcsolatot is fenntartanak. Kíváncsi vagyok megoldásaitokra.
