Eating out a girl's asshole and pussy at the same time.
Step by step instructions to tossing a tuna salad: First you get your girl in position like you normally would to eat out her asshole, with her on her hands and knees with her head down, back arched and her butt in the air. But instead of sticking your tongue directly into her asshole, you stick your tongue in her pussy and lick up her clit, up her choda and then into her butthole. Go back down and repeat (many, many, MANY, times.) Then try reverse, this time with your tongue wiggling all the way down. Then go free-style wildly licking, sucking and kissing crazy all over the place, ensuring her tuna salad is utterly and thoroughly tossed!
