Is it the Girl or the Speedo?

[Papadoop]

Bit of a random one this but has anyone ever fired their load in their speedos when being around hot women?
It happens to me quite often usually if im attracted to the girl but its never happened wearing board shorts.
Wearing Navy Blue Skin tight Swim Briefs on Sunday I was in the Sauna when 3 hot girls walked in, 2 asian girls one a bit chubby but had a white bikini on, her mate a black swim costume, brown long hair and a nice butt and a curvy pretty devon girl with them who sat by me and as we chatted her cleavage was on show with her hair all wet and her hot legs were close to me as I chatted to the girls and tried to fight it I had to pretend to mess with my water bottle as I started jizzing rapidly in my briefs luckily they didnt notice. Its always when i wear speedos and never shorts they just make me too horny and sexed up
