The next step is lessons in foreplay. Of course almost instantly, he will want to rip off your clothes. Do not let him. Setting the ground work for an amazing orgasm is about building erotic tension, which takes time. Slow him down and focus all his attention on where you want it most, try a slow stripping session. Example ease off your shirt, but keep on your bottoms, he will automatically zero in on your breast. Then let your fingers do the coaching: touch yourself like you would like him to. With your fingertips trace circles around your nipples, cup your breast, knead them gently (or firmly) and he will get the picture.
Another trick is to bring chocolate sauce or any other tasty substance to bed. Spill a little on the spot you want to feel his mouth, then invite him to lick it off. This is a fun way to make him realize the sides and bottoms of your breast-not just your nipples- crave his kisses and licks. Coyly stop him when he attempts to slide off your panties (drop line like "uh-uh, not yet" to let him know your being being playful) will make him explore your lower abdomen and upper thighs with his mouth.This will also get him to stimulate your clitoris over the fabric of your panties, which is of course a sexy way to heat you up.
This is also another instance when a DIY move pays off. Allow him to watch you put your hand over your pubic mound, with your fingers on your clitoris, and massage it and the area around it using circular and Up-and-down movements. Then carefully place his hand on the same spot and let him take over.
When you want a more direct contact, move the crotch of your panties over to give his fingers access to moving the fabric so that your clitoris is exposed but most of your vulva i still covered to direct him to the hot spot. As he continues to touch you, let him know what works, by increasing your moans, or naughty talk whenever a stroke sounds amazing and being silent when one does not. Guys learn from direct feed back. Things like "Omigod, right there feels so good" will imprint these moves into his brain.
