You'll watch them awkwardly bring up the subject of how friends of the same sex can have "feelings," as they have a glass of wine and some strawberries on the sofa.  You can tell that one of them is more relaxed than the other about their approaching encounter. After flirting and some warm-up kisses on the couch, they head for the bedroom, where they spend over a half hour enjoying each other.  They start out with some very nice kissing and caressing, then take each other's clothes off and wrap themselves around each other.
