Morgana was a Siren Queen, and even if she wasn't actively seducing Ian, her innate features like sweet voice, glazing eyes, intoxicating scent, and aura were impacting him all the time.
Moreover, with her hot and seductive body in scantily clad clothes and her submissive attitude, how could Ian control himself?
"Glrk... ugh..."
"Slurp..."
"Glrk..."
The moment his rod entered the warm embrace of Morgana's mouth, Ian went crazy.
He suddenly grabbed her hair while pistoning in and out in abandon. Of course, he didn't go too forcefully, but he was fast, causing Morgana to gag in reflex.
The slick and moist feeling, with the warm cave surrounding and caressing his rod from every direction, made Ian feel so good that he couldn't help but groan in pleasure.
"Mmmm~~ Slurp!"
Although Ian was rough at first, and she was caught off guard, Morgana was a Siren, after all. Not to mention, she was a wizard with extreme power.
How could such a low-level attack on her mouth do anything?
