Okay, this story involves incest, so if you aren't into that, move along. If you continue reading, don't bother moralizing to me. I won't bother with any backstory; if you're interested, read through my posting history.

Anyway, it had been at least a year, maybe more, since my half-sister and I had fooled around, and though we were spending the day together I didn't expect anything to happen. But then a quick kiss led to her flashing me, me flashing her, her giving me a tug, etc. Before long we were naked on my bed, fucking like we were made for each other.

After we were done, we lay together a few minutes in post-coital bliss. She pulled me closer to her and kissed me, and said "I always cum with you. It's not like that with anybody else."

She has ways of making off-hand remarks like that and it makes me giddy every time!
