Her pussy was perfectly framed by her thighs. Her lips were partly open, my come starting to seep out. I was panting, coming down off my orgasm. I wanted to taste it, to see what it was like, but the urge had left me.

As if on cue, she pushed me onto my back, swung her legs over my head, and settled down onto my chest, pushing her leaking cunt onto my face. Then she started moving her hips, using my chin to rub her clit. I could tell she was going to come again, and soon.

I thought “what the hey”, stuck out my tongue, and sampled the result of our coupling. “Not bad”, I thought. I swallowed, and started licking her pussy in earnest, capturing each drop of our juices as they came out, until all that was left was a steady stream of her own lubricant flowing from her arousal.

Suddenly she stiffened, her body vibrating as she came. Then she fell limp on top of me.

“Now THAT is how your wife should have done it, none of that other mucking around”, she said. “Thanks sis”, I replied. “Hey, what are big sisters for”, she said.
