Update:
Dear god I'm on cloud nine!
It had been a few days since I had any real interaction with her and I was beginning to think our little back and forth was over.
Especially after what happened yesterday.
I was sitting on the couch watching TV when she came into the room. Once again she starts talking about her sunburn. I asked her if she had taken yet another sunbed and she said yes. She complained that her back was really itchy because of it and said she wished someone would scratch it. She then lifted up the back of her shirt exposing her red, sun burnt back, all the while keeping her front side covered. I wasn't sure what to do but I was empowered by our recent exchanges so I said meekly "I'll scratch it for you if you want". She immediately shut me down hard by pulling down her shirt and saying "no thanks, it's fine". I was taken aback by how abrupt she was with me but I just figured that maybe she had finally come to her senses and realized that maybe she shouldn't be behaving the way she had been behaving lately.
I pushed it out of my mind and just went back to enjoying the sight of her humongous boobs on the down low.
Then it happened again.
My nightly routine is to sit at my computer and either play games or surf the net. That's when she usually comes down and talks to me. Well, tonight she came down and started chatting. I had figured our little sunburn sessions were over so I didn't even bother asking her about it (plus I didn't want to risk sounding pervy). No sooner had I thought that when she suddenly says to me "yeah my sunburn is still really bad". I immediately move closer to her. I didn't even mention it but knowing that that's my cue I say "Oh yeah, well let me see."
First she lifts up her shirt exposing her belly almost down to her pussy (It's actually pretty red) and I reach out and rub her stomach. "Oh wow" I say. She then turns around and says "look, my ass is all red". She pulls down her pants slightly but enough for me to see the crack of her ass and the white triangle left behind by her thong. I decide to go for it, and run my finger just above her ass crack "Gee that is burned" I say. She then spins back around, her shirt still lifted. I then decide to try my luck again and say "okay, how're those nipples doing? Lemme see em". Once again she objects by softly saying "I'm not showing you those" so thinking fast I cut her off and say "okay just show me the under boob". Which she does! As she does she inadvertadly exposes her nipple and most of her boob. Without thinking I reach out and touch the exposed underside of her breast. She then straightens her clothes, tells me goodnight and walks off.
I'm still reeling from it. Did I dream this?
