I got my sister dickscared, but this time she attacked [Part 3]

From the rest of the one month and half after the last history, I kept letting my sister "spy" on me while I masturbate and this made her get courage to the most absurd things she done for taunting me.

So, for a month and a half, I kept doing crazy stuff for taunting her like bathing with the door opened, walking naked in my house before she arrived from her walk, passing by her room all commando knowing she's going to see and watching porn without headphones for her to listen. All of these things haven't pissed her off or made her done or say anything till the day she decided to fight back.

One day, I was watching on the couch just minding my own business when my sister left her room and asked if I had seen her towel cuz she's about to bath, I told her no and she started to search around the house, but before she started to search, she left her phone on the couch arm right next to me opened on a nude of her.

The nude was literally her seating on her side with one lag wide open explicit showing her ass and her recent shaved pussy. You may think now, "putting your nose where you're not supposed to?" But the second she dropped her phone there, my eyes were supposed to cross with the screen and turn back to the TV, but I couldn't take my sight off that majestic image before the screen turn itself off after some seconds.

That shit was marked in my mind for the rest of the day cuz there's no way she did that "by accident," mainly bc what happened next, when she took her bath and left the bathroom, she passed by the living room to grab her charger on the cabin and literally bended her body in a very unnecessary way which allowed me to see her bare ass and part of her pussy and God damn, that was a sight. The other day, when she was doing the laundry and again asked me for help, I went to the garage to help, and she said "I need to hurry and take a shower before heading to work, can you finish her for me?" And okay, this one favor was more complicated, but before I answered, she started to undress right in front of me, she even turn back and took off her pants so I could see her ass in her panties and after stutter like a mf I say and dry "okay" and she left for the bathroom without saying any much.

This last day was the best cuz she decided to sunbathe on the backyard (our whole yard was walled and no one could look from above of it), she head there in a bikini that was almost saying "would you mind to fuck me pls?" She could just put the sunscreen by herself, but again, she asked my help and said "I need you to help me with the sunscreen cuz I'll need to text my friend and can't use my hands now", I was just about to complain when I rethink and noticed that I could just feel her body without looking "pervert" (at this point, we're both already know that each other are the most naughty mf ever lol).

I'll tell the rest of the history after I get back from my trip to my parents' house, so get ready for part four.
