When Otis was returning from the bedroom, he heard a muffled voice coming from inside Serena's room. He couldn't resist the urge to investigate.
He crept up to the door and pressed his ear against it, trying to make out what was being said. At first, all he could hear was a soft murmuring sound, almost like a low, constant hum. But as he listened closer, he began to make out words.
( is this Serena's voice?) he wondered, his heart racing with anticipation. Without thinking, he quietly opened the door and peered into the room through the gap.
What he saw made his breath catch in his throat.
"Hmm... fu, ah... ah, nhh... nfuu♡"
Serena was sitting on the edge of the bed, her eyes closed and her face flushed with pleasure. Her hand was between her legs, gently rubbing herself through her lacy pants. It had been a long time since she'd masturbated. The last one was before she came to Otis life as a teacher.
