He was taking a shower, frustrated

Ethan found that Colossus, in his human form, all alone on the showers of the locker room he was naked and under the shower rain.

The tall beefcake was trying to get his body cleaned and was missing some spots...he just couldn't reach them (or that's what Ethan tough).

Ethan stranded undetected on his corner admiring the hulking frame of Piotr: he was strong and extremely muscular, with huge round buttocks and an incredibly big cock.

Ethan had so many options on how to approach this scenario he just had to choose how far was he going to push this (or even if he was going to do it at all)
