[Katniss]

~ Sensory deprivation makes the other senses {taste, touch, smell} more intense. Blindfold her and feed her stuff: strawberries, chocolate, ice chips, chocolate syrup, etc.. Rub it on her and lick it off too.

~ Insert the bullet vibrator in her and leave the room. Let her stay there for a decent amount of time. Instruct her that she is not to orgasm until you tell her to.

~ While she is tied up and blindfolded, find the most sensitive parts of her body {based on how she reacts} with your tongue, or by nibbling with your lips. You can also use a feather or your fingers. It might be fun if you insert the dildo gag to limit her talking too.

~ If your girlfriend is into being spanked, spank her until she begs you to stop. Don't just spank her ass, tease her clit and other sensitive area of the body.

My suggestion is to start slow. Touching, teasing.. pay attention to the details. The way her breathing changes, for instance. Take your time, and go from there. Don't stop until YOU are worn out! Enjoy!
