sex and swimming

So last night I remembered to remember some of my dreams...
It begins with me helping my parents move into a new house down the road from their current house. . .omg, the infamous "she" is in my dream again.  (read previous posts to find out who "she" is)   she is on the road behind ours.  her bosses vehicle (an old acquaintance)  is in her parking lot.  I think to myself. . .ew, but she is always talking about being lonely, (a poor excuse btw) she ends up coming over to talk to my dad. . .I ignore it. . .dream moves on to the san antonio town hall.  I am swimming in a pond with others and the pond extends into the town hall.  I swim out of the water and swim over the steps leading out of the water.  (i recently visited some people at our town hall, prob incorporated this into my dream)  I see a young woman and "swim/fly" over to her.  she leads me to an office with two other young women.  I begin to have sex with this girl on their desk while kissing the other two girls. . .the first girl dissipates into thin air. yea,  I know. . . without going into much detail, i being having sex with one of the other girls.  She is riding me because that provides the most stimulation for her. . .then I wake up. 
Again I would like to note. . .I am hoping for even sex dreams to be absent from my mind, but sometimes dreams are hard to control.  I would like that only my wife be a part of my dream life. . .haven't mastered that ability. . .
