Me and my roommate dedicate a day to a certain thing and every day its something different. One day we decided to dedicate the next day to vibrators and for 24 hours we kept a vibrator in our pussy. If we were jogging, sleeping, eating, visiting family, on the phone, shopping, whatever we still had to keep the vibrator in. We both ended up cumming multiple times throughout the day. It did take longer to sleep since the vibrator was keeping me up, my roommate had the same problem.
