Venturing into the wild and kinky

Recently, I've been wanting to spice up my bj game, and try rimming as well. Never tried rimming before, and bj, aside from sucking and playing with the balls, parang wala nang ibang variations.

What do you guys do that makes your partner lose themselves? Or, anong ginagawa (ginawa?) sa inyo na sobrang memorable? Toys, techniques, add ons like flavored lube or something, basta napa-wow nyo ang partner nyo or napa ungol nyo sa sarap ng kapartner nyo.
