My sister-in-law's sweater slowly, seductively sensually rises up over the perky mounds of her shapely breasts as she engages in a naughty little strip tease. And I can't help but stare and enjoy the breasts of a woman that hasn't raised any children yet. My wife used to have amazing curves, and her sister definitely reminds me of that. Must run in the family!

I told her I didn't want to see them and kept protesting, no matter how eager and persistent she was, but now I can't stop staring as she casually leans against the countertop in the bathroom off the master bedroom. The cute colour of her areolas, the slight perkiness in her nipples making me wonder how much longer and firmer they would become if I were sucking on them.

I am sure agreeing to let her stay over for a week after she broke up with her fiance hasn't made matters easier. Nor has my wife working overnight as a nurse on a Friday night. Or having drinks and pizza and watching movies on Netflix tonight. We flirted a little and chatted...and then she leaned on me and said she missed having a guy to cuddle with. What was I supposed to say? "Get lost?"

Either way, here we are. My eyes bulging as she reveals her body to me, one inch of hot, tanned, sensual skin at a time.

Wait. I can't be thinking about my sister-in-law this way. How did she talk me into sneaking up here alone with her? Why did I agree, knowing it could ruin my marriage and split up my family? Why have I always had a weakness for her? What do I do now?

(Hmu to sort out the details of how we got here and where go from here. What is our backstory and has this been building for a while? Is it mutual or has the seduction been one sided?)
