When she has her first orgasm, keep goin...she's just getting warmed up. Now is when the really sweet juice starts to flow. When she arches her ass up off the bed, keep goin....use the opportunity to run your hands over her ass and back. When your jaw gets tired, keep goin....think of it as forced reps. When she clamps her thighs down on your face so hard you can't breathe keep goin, she'll relax in a minute or two....you have been doing your cardio, right? When she finally does relax and is in that semi-delirious state, put your hands behind her knees and push them up toward her face, now dig into that chocolate starfish....ask her to spread her buttcheeks for you. She probably won't hear ya but if she does really go in for the kill. Fuck her ass with your tongue. If she doesn't give you booty after that she never will. If she does give you booty give me her number so I'll know my technique works in advance.
