master, I want more!

Lyra says, almost demanding. She stands up, walks to you and grabs your half hard dick, strongly jerking it up and down. "Have it." You say smiling. "Thank you master!" she says smiling at you like an angry upon your permission. Without further ado she turns around, holding your dick up and ramming herself on you, slipping your cock into her ass. "Haaaah yeah! More!" She screams, but you grab her hips and prevent Lyra from riding you. But that doesn't help, you realise, her ass is pumping and jerking you without her moving her hips!
