She might have been slightly surprised when a very tall man with a tattoo on his right eye answered the door and announced, in a booming voice, "Awesome, my sandwich. And student! Come in. I was just getting ready." He relieved her of his meal and led her into the apartment.
After placing his meal in the kitchen, the man went behind a door and tossed his shirt out behind him, followed by his pants. He continued talking all the while. "I was expecting you a little later, so I hadn't changed yet, but it's fine. I was getting hungry. I have to eat more often than most people because of the whole superpower thing."
A woman came out with the same tattoo on the same eye as the man, adjusting a sports bra around her chest. Aside from a rather tight pair of sweat pants, she wasn't wearing anything besides these two garments. She bounced a few times to test the bra's hold on her bust and picked up the sandwich the man had placed on the counter earlier. "Ready to go?" Her voice was also deep, but clearly feminine. "By the time I'm done with you, you'll be able to throw down with the best of 'em." She took a bite of her sandwich and added, through a mouthful of bread and meat, "Thanks, by the way."
