Cassandra bit her lips in shame and spread her legs just enough for Shennong's hand to make its way towards her vagina. She still enjoyed Shennong's touch, but the extra pair of eyes made Cassandra somewhat embarrassed to act freely.
Shennong started moving his right palm towards her vagina while caressing her inner thighs.
"Ummm~"
When his fingers reached her vagina, Shennong gently caressed her labia with his forefinger, eliciting an expression of pure ecstasy from Cassandra. Her body had already grown accustomed to Shennong's touch after a week of his affectionate attention, and she knew that without the sensation of his fingers, she would feel as if a significant part of her life was missing.
"~Haaah~ ~Umm~ please ~Aahh~"
Lily was flabbergasted by everything that was happening in front of her, but she was not the only one. Outside the door, Percival was listening to everything happening inside the room.
