"I always undress you, so isn't it only natural that I ask you the same thing?"
Because Matthew never continued their activities or touched Ruby before Ruby undressed Matthew, Ruby finally tried hard to get rid of all her embarrassment and immediately sat down in front of Matthew.
Her hands shivered as she touched Matthew's button and slowly opened it. Every time Ruby managed to undo a button, Ruby could see Matthew's muscles beneath his clothes.
Ruby blinked several times and tried to avert her eyes when she had an intrusive thought to touch Matthew's stomach muscle, which looked tempting.
Ruby bit her lower lip, then ventured to touch Matthew's stomach. However, she was surprised when Matthew suddenly withdrew her hand and immediately put Ruby's palm on his stomach.
"What are you doing?!" shrieked Ruby.
Matthew smiled crookedly. "Sweety, we've done this many times and even spent days tossing and turning in bed. However, why do you still feel embarrassed?"
