Use more space, full 180° before you (better 270°) should be full of action, not only the very narrow view right in front of you. Girls should play with each other all around you for visual overkill. Thy should not only "be there", staring at you all them time. They should be hot and horny all the time and the whole atmosphere should be very relaxed and very ecstatic with everyone having the time of their life. I know that some people expect these scenes to be more like a BDSM scene in which all the girls only have to please their master but imho that sucks and takes away all the fun. The best scenes are those in which everyone just have fun and let loose instead of being focused all the damn time.
And some story would be fine, like the ones we suggested. I like my porn to have stories and to fulfil fantasies.
