This guy's actions look bad. I don't think the girls took anything against their will but Anna was VERY high/drunk when he was with him which is usually a sign that you should not go there. Maybe they know each other well and this is something they've already done more sober but without context it looks really really bad.
Also he was very handsy with Stella when she was half asleep on the couch and then again at the end after he left anna, I see no excuse for that.
