"They're so hard you could grind cheese on them!" Armin said.
"Let me try." Eren rubbed a block of cheddar against Mikasa's abs. It was shredded in minutes.
"Holy shit," Eren said. "He's right."
Mikasa smiled smugly. She wasn't the type to brag, but she had to admit—she had some pretty nice abs.
So the three of them shredded all the blocks of cheese in the food supply and made everyone a cheese omelette with a dash of ab sweat. Everyone except Eren, who Mikasa payed back in her own special way.
"Open wide." Mikasa fed him a spoonful.
"It's amazing," Eren said, his mouth drooling.
"It's only natural," Mikasa said. "After all..." She whispered into his ear. "I used my vagina." Mikasa snapped her panties against her thighs.
Eren came harder than he had ever had in his life.
