My sister photographed on the street

My sister is 25, very pretty, with a fitness body, an ass that all my friends desire and she loves knowing it.I was waiting for her at our apartment, we lived alone. I looked out the window because she told me she was arriving, and I see her from a distance, her hair color and body are unmistakable, besides there wasn't much people, shecame from the gym with a black leggings that fit well on the ass and above a blue topOn the street across the way, a man was walking in the opposite direction and kept looking at her a lot, until now everything is normal, she always draws a lot of attention andIt's normal that they look at her a lot,To what I see the guy stopping while she passes by his height and crosses the street towards her, changing direction to follow her. She was behind him and didn't see him, the first thing I thought was that he wanted to rob her, I thought of calling her to warn her but it wouldn't have done any good, to what I see asThat type speeds up his pace to get close to her and pulls out his mobile, holds it with all the boldness in the world and points it at her., and then he checks his phone, at the moment I thought 'just took a picture of my sister's ass?' I thought maybe I was being paranoid and just checked his phone, only to see him lift it up again aiming straight at her butt,the very hd was walking behind my sister while recording her booty.She didn't seem to notice that this guy was coming up behind her (or maybe she did) and sometimesHe was beating off his cock.So thatAh was I, looking at my sisterapproach the departmentWhile behind her was coming a guy filming her whole buttWhen I couldn't do anything. When I was about to reach the building, this guy says something before leaving, while still looking at my ass and adjusting his cock with his hand. She turns her head, the guy is already leaving, and I see my sister had a slight smile on her face,Maybe that dirty thing he had said to her, and she was smiling at it the most.He arrived, I asked him how he had been and he didn't tell me anything about what had happened a moment ago, I found myself tempted to ask but I held back. AnywayIt wasn't the first time I had seen an unknown person filming my sister.On the street (known people, even more so), one of the best was whenWe were standing on the subway, she in a mini skirt,the doors open and a guy walks by her side with a phone in hand recording upwards, with all the world's tranquility and impudence he passesBehind her, he subtly puts his phone between her legs and records her under the mini.and it came out like nothing from the wagon, it was so fast that maybe the rest didn't even notice but I saw it clearly, Instead of bothering me, I was surprised by the guy's bravery and how well he did, even I wish my sister wouldn't wear a thong that day so she'd have a better videoThe only thing I don't like about my sister being big with me on the street is that they don't share the videosThey use them to masturbate alone and don't let others do it too.

Besides, she knows they take her picture a lot on the street, I've heard her talk about it with her friends and it seems she enjoys feeling desired quite a bit, soIf she enjoys it because I should bother myself?
