I was in a very odd situation earlier. After getting my shipment of pheromones in, I sprayed a bit of Turn Up the Heat in my hair, just on a whim. I was upstairs on the computer, and my mom brought over my younger sister (she’s 16, I’m 17) and she came upstairs to see if she could use the internet. I was at my desktop right next to her programming. After a little bit, she seemed to get a bit antsy, so I moved to a gaming console because I thought the effect might be making her uncomfortable. Then I got an e-mail notification, so I asked her if I could use the computer. She got up and I started checking my e-mail, but when I stretched at one point, she started touching my arm, then stopped herself. When I got done, I started programming again, and she become even more anxious, eventually getting up and going downstairs in the middle of writing a comment on a website. Not sure how to deal with this. I didn’t mean to make her feel weird or anything, but I figured there wouldn’t be much of an effect since she’s my sister. I guess I could explain to her that I was wearing sexual pheromones, but then that would probably be awkward as well. I guess I just need to be really careful with TUTH from now on.
These kind of stories(experiments) are just as important as the positive ones. Thanks for sharing.

Fucking a
Incest is the best, put your sister to the test?
IM JUST KIDDING!
@_@ thats an eye opener
I think you should do this again, just to see if you get the same reaction.
Would be curious to know if its a one time thing due to first exposure, or if its going to be an on going effect on her.
Definitely a good idea to use her as a guinea pig with the TUTH. At least we know this stuff is no match for family relations, it must work really good on girls who are outside of the family.
Don’t forget though, that the smell (the orangy smell that comes with these pheromones) could have made her uncomfortable.
I wouldn’t exactly say it’s a good idea to use his sister as a guinea pig, but the results are interesting. At 16 years old, the poor girl’s already going through all sorts of chemical, physiological, and psychological changes. No need to introduce a potential freak-out factor of finding her brother sexually attractive.

I agree with data4. I understand the temptation to try it on her again and see if the reaction is duplicated, but she already has a number of hormonal and mental problems. I don’t think even potentially making myself sexually appealing to her would do anything for her esteem, and would probably be plenty of food for her psychiatrist. I do have some attractive non-blood first cousins though. 
Who knows?
If she hadn’t liked the smell, I’m fairly sure she would have told me. She usually tells me if she doesn’t like my cologne or deodorant. She didn’t say anything in this case. She just started fidgeting and being antsy.
Now you can use that wisdom/power for GOOD.
I wouldn’t wear it around your sis for experimenting sake … you now KNOW what it does and that it works.
Proceed with caution and watch your step. 
Wow that’s a crazy story… at least you know your bottle of tun up the heat works.
At least it wasn’t ya mom!

Just ordered a bottle due to this post!!! amazing and thankfully…I don’t have a sister
My son acts very aggressive when I’m around him wearing pheromones. I have to worn him before I put them on so that he can recognize the effect that there having on him. He’s 22 and uses mones also. As for your sister maybe you could tell her and them and it wouldnt be a big deal. She might want to purchase some for herself.
