Hikaru was a bit startled, he didn't think that Selvih would contact him right now. Even though Hikaru knew Selvih wouldn't be jealous or angry that he was sleeping with Saraya, the situation was still awkward.
He felt Like a man whose wife found out that he was having an affair.
Hikaru frowned at Saraya, signaling her to stop, he had forgotten that Selvih could only contact him with her thoughts and that she could not see or hear what he was doing.
However, Saraya showed a very sly expression, she released his 'weapon', but she didn't stop. Saraya then stretched her sticky pink tongue and licked the top of his weapon, startling him.
That tongue gently stimulated the sensitive points at the tip of his weapon and this caused him to shiver a little. Saraya was indeed a Succubus, it seemed like she was born for this kind of thing.
