Leos was 6 weeks out from finishing her final deployment when her and her Sergeant were bullshitting in the mess hall one night. They were pretty close and the conversation ended up about their biggest fantasy. Really it was Leos giving him shit because she caught him looking at another female Marine during PT (physical training).
He told her that one of his biggest turn-ons were women working out. He said if he could have one wish or superpower that didn't really exist, it would be to have x-ray vision so he could see what women looked like under their clothes.
She may have hazing him a bit for it but I can't say I don't agree. That would certainly be up in the competition for my three genie bottle wishes! This video is from her Sergeants fantasy perspective.
