Two teenage girls, Lily and Emma, were in the bathroom, both naked except for their heels. They stood in front of the mirror, applying makeup together as they chatted about their day. Suddenly, there was a knock on the door.
"Who could that be?" asked Lily, her brows knitted curiously.
Emma shrugged, "I don't know. Why don't you go have a look?"
Lily opened the door to reveal her brother, Jack, standing on the other side with a grin on his face. "Hey guys, can I borrow some towels?" He asked innocently, not knowing that behind him, Emma had snuck into the bathroom.
As soon as Jack turned around, Emma pressed herself against him from behind, her bare chest flat against his broad back. She let out a soft sigh.
