My Curious Step Daughter

I've been her step dad since she was 9. Her dad isn't in the picture, so she has some daddy issues. She is a beautiful 5'7, 125 lb brunette, blue eyes, long curly hair, small breasts, and slim figure. I'd never looked at her as a grown woman, but she turned 18 last year. We were at the beach last summer, and the family was getting ready to go out for dinner. My wife had ran her brother to the store while I was relaxing on the bed after my shower. My SD came into the room to iron her shorts and top before we went out. She ironed her clothes, stripped down to panties and bra and changed in front of me. I took it that she was just comfortable with me like a dad (I don't have a daughter of my own).

The next week, I was at home in our spare room ironing. I was wearing boxer briefs that pretty much shows the outline of my penis. She came out of the bathroom and opened the door and stuck her head in. She said, "I heard something and wasn't sure what it was.", she closed the door, but immediately walked back in and sat down and started talking to me about her dental appointment. She's not a chatty person, so I felt she was using it as an excuse to check me out. I caught her staring at my package twice but looked off as soon as I made eye contact with her. Since she'd never had a serious boyfriend, i took it that maybe she was just curious. A couple of days later, I'm in the shower. I'd shut our bedroom door, but left the bathroom door open to help with the steam. Suddenly I heard my SD's voice.. "Is the cocoa butter body wash in their?" (That body was is ALWAYS in our shower). I had a towel hanging over the etched glass door, so I didn't see her, but she could obviously see me from chest down. I realized she was standing in the bathroom. I didn't make a big issue our of it, handed it over the door and she walked over and took it from me. I knew she could see everything. I didn't mention it to my wife. Twice lately she's walked in while I was naked and never acts like its a big deal, so neither do I. More recently I was standing in our bathroom bringing my teeth and was naked. She came in and grabbed a brush, stood beside me and started brushing her hair while looking in the mirror and glancing down at my cock while talking to me about school. I said, "Well, I guess it doesn't bother you that I'm naked.". She said, "I've seen some guys i go to school with that texted their pics to some of my friends, but I've never seen one in person until I saw yours but your's is bigger than the ones I've seen." I said, "Well nudity isn't a big deal to me, but im not sure your mom would appreciate you being in here while I'm naked.." she said, "please don't tell her. I sure as heck won't."

Last Saturday, my wife went shopping with her sister, and my SD was at home with me. She went unto a spare bedroom to ten in the tanning be. When she came out, she walked into our bedroom completely naked. She made no attempt to cover her small, perky breasts with hard nipples, or completely shaved pussy. I said, "ummmm... Well hello." She said hello, smiled and walked i to our bathroom to retrieve some hair products, then stopped to talk to me about how she hates the way her skin smells after tanning and always gets a shower after. She clearly was giving me the full frontal, and allowing me to look at her pussy.

It seems she is really liking the safety of seeing a naked man and being seen by one without the pressures of sex. She is still a Virgin and actually is a very good girl, which makes this all the more shocking.
