A nice little game I like to play is to have you watch yourself masturbate using a mirror then describe it afterwards.
The set up is simple, preferably use a large, floor length mirror and sit in front of it on the floor. Alternatively set a smaller mirror on your bed then position yourself so you can watch as you play with yourself.
The actual masturbation has to follow these instructions.
Start by simply spreading yourself as wide as possible using your fingers, no actual rubbing of clit or penetrations just opening and looking. Time this using a timer on your phone to last for 5 minutes, then move on to part 2.
Now you can finger your hole, no clit touching just fingers in the vagina, push them deep and spread wide and at all times keep watching as you do, again this lasts for 5 minutes.
Take one of the objects you have been using and insert it fully watching it disappear then slowly fuck yourself with it. Keep going for 5 minutes again.
Finally edge by rubbing your clit again with the object still inserted, hold it in if it wants to slip out and keep watching yourself. Keep going until you edge then quickly fuck yourself 5 times and stop. Wait to cool off then edge again, and repeat 3 times in total. Don't cum yet, report back for more instructions.
