He paid particular attention to the breasts, I suppose looking for lumps. I winced in sympathy as he tugged the nipples down, and when he finished the... stayed extended and swollen. Then he snapped on a pair of surgical rubber gloves, and got out what look like a tube of toothpaste. However, what came out when he applied it to her bottom was clear and glistening. I suddenly realised what he was going to do."Is this really necessary?" I started but her gasp told me that his finger was already in. You gonna experience... you`re gonna have sex...". I cut him off by saying:"Dad, I know all of this. Why are you telling me this? This is embarassing."

Wha...", I strugged saying because I didn`t quite make out what he was trying to say."We want you prepared for life sweety" my mom said. "So let`s get started" said my dad. I was still trying to understand. This was not going to be the last time was something I knew for sure... and it wasn't.For the next week we would meet on line and chat about our day. More and more I noticed that each evening she was dressed more provocatively. One night she would be in her satin blouse and skirt.. another night she would be in tight jeans and heals. I couldn't think about much else each day. I couldn't wait to see what she would be wearing that night.The day before I was going to come home she called in. Standing between her spread legs was a guy, Steve, who Jay recognized from school. Steve had graduated a year before him, and Jay thought he was a total loser. But, as he watched the scene before him, Jay had to admit, Steve had an impressive cock – maybe 10”, or so – and he was using it to slam into Amber’s pussy like a piston.Naturally, Jay couldn’t let this opportunity go undocumented, so he pulled out his cell phone and began taking a video of his sister getting absolutely pounded by.
