She cautiously lets her tongue slip out of her mouth and licks along the length of his cock that she can reach and she rubs her cheek against it in a loving way.
"Good slut," he says and again pulling her by her hair he lifts her up so that her unbound breasts are pressed against him with his cock settled in the valley they form.
As she relaxes she tries to control her heartbeat which is racing from having been scared that she displeased her master, having flash backs of when she was at the slaver's camp. As her master clears his throat, she jumps a bit and with his cock pressed against her chest in the valley between her breast she gets an idea and shivers with the delight and she presses her breasts together enveloping her master's cock. This action shocks but pleases her master very much and he starts to lift his hips, pumping his cock slowly between the silky soft breasts of his property, his slave.
Without any different commands she keeps up with it and not being able to resist, still having the taste of his delicious cock in her mouth she licks out at the head of his cock as it comes up and toward her face. "Good girl slave, but work your mouth more. I like hot and wet slaves," he says calmly and that almost frustrates her wanting to please him till he can't control himself. He lets his fingers slide into her soft hair, marveling at its texture and then he grips it into his fists and pulls her head down further so more of his cock slides into her waiting mouth each time he thrusts his hips up. "Umm nice," he moans out.
With her master pushing her head forward she can now take the entire head of his cock in her mouth and she sucks on it hard for the brief moment it is in her mouth during his pumping. As this is going on she lets herself drool down onto his cock and her breasts making the valley slick with her saliva and hot from the friction and her own skin is heated as well. With this her master moans slightly, starting to lose himself in the sensations and he grips her breasts and pulls them down pushing them together harder, and he thrusts up harder and faster and his pumps even more of his cock into his slaves waiting, hot, wet mouth.
