First of all, if you plan to do a 3some, be sure that the girls are bi. My mistake was that I assumed that in the first place. Not true with Tina and Lina. The girls are straight so don't expect them to show passion for each other.
The risk you are taking by booking a duo is that they can start talking with each other and forget you. Unfortunately this was the case in our meeting. The girls started to talk with each other in ukranian so I understood nothing. Half an hour spent by laying on bed watching tv and trying to understand what they were talking about :/ Not fun at all.
The sex was average. No passion from neither girl. The highlight of the meeting was eating Tina while Lina was riding me. Sounds exciting, but not that much really.
To sum up, the experience was not worth the money. Sorry girls, but I'm sure meeting you individually would be more fun. Their attitude is nice and sweet, but the service isn't. Don't recommend duo at all. Meet them individually...
