The cocks were seen while they were pissing in a public toilet ...

They had to piss next to each other and they couldn't catch a glimpse of the one next to it. these are things that happen, you see the other's cock, you get horny and if you see that he is receptive, you end up making out. they gave everything, he did not stay in a couple of straws, or joke. they got into the toilets and fucked their cocks and ended up fucking.
