"I need a shower"

"I really need a shower" you state, "I was in a hurry getting ready toda-"
"It's ok" Hayley says.
She's not being very shy today, you think. You start walking towards the Men's locker room.
"Where are you going?" Nina asks.
"The locker room." You answer.
"Two girls, one guy. We're using the girls."
You didn't see any reason to object to it.

You enter the girls locker room. Nina and Hayley open their lockers, and take out soap, shampoo, deoderant, perfume, make-up and bodywash.
"Wow, I'm not going to crossdress or anything, am ?" You joke.
"We need showers, too" Nina says in a flirty voice.
You walk over to the showers. You strip off your cloths.
"Is that... Your dick!?!" Nina says, exitedly.
You glance down at your rock solid, 10 inch long-3 inch thick dick.
