It was during the unfortunate circumstance of you pulling back when she was dropping that led to your dick pulling free from her completely, a wet pop signalling the disconnection... and apparently another orgasm for her, as you felt her juices erupt onto your shaft and balls, even soaking your thighs a good deal. Your head ended up laying atop her clit, the little button winking rapidly as she squirted. You were damned if she wasn't like a waterfall with how much she was gushing.
