A big family has a yearly reunion. They get together in a big house for a long three-day weekend. There are the usual meals and conversation and pictures, but the main event is the glory hole.
It is a row of glory holes, really. A wall separating two rooms. Girls go in one room, boys go in the other room. Everyone (and I mean everyone, all ages) takes at least one turn, and most go in for two or three. By tradition, you’re not supposed to know who was sucking whose dick. However, the family engages in endless speculation, based on who was seen going in at what time, and who came out smiling, etc. It’s all a good time.
I probably don’t want to role play this. I just want to chat with someone about all the possible combinations, and how people would react if they knew who they were paired up with, and who probably knows and enjoyed it anyway. Little girls sucking. Little boys being sucked. The new wives who have married into the family and what they think about it. The kissing cousins who paired off later for a little nookie.
