You have to communicate your desires to the ladies involved. I've done multiple doubles with 2 ladies. I've has mixed experiences. The first time, there was no girl on girl action. I had sex with one and then had sex with the other. There wasn't even any massage or caressing or encouraging going on. Literally, one girl just watched and waited her turn-- absolute dud of an experience. On the other hand, I've had two hot experiences where both girls were into the girl on girl action. Don't know if they were really bi or really drunk-- LOL. On one occasion, the girls were too much into each other. I still got aroused but left with no place to cum
