Nice and slow

She gently pushes her cock inside your mouth. You open wide, letting it in, but at the same time, instinct tells you to bite, as it just doesn't fit, and you almost do, but Mara says:

"No, Puppy, no teeth! You don't want to hurt me, do you?"

You try to reply properly, but the mouthful you're given prevents you from doing so. Instead you just make a sound representing a negative response.

"Good Puppy." She says, "Now, be a dear and suck as I move in and out."

Having little choice, you do as you are ordered. While the motions feel strange, you notice that, indeed, the whole thing feels natural to you. After a while, you even start getting into it. Mara's soft moaning helps too.

Mara's cock is fully erect now. Noticing your confidence, she picks up the pace slightly. In and out she goes, moaning louder and loader, as you keep sucking, increasing your enthusiasm. Finally, you feel her cock starting to twitch.

"Puppy," she gasps, "keep sucking... DON'T STOP!" She says loudly, almost screaming, grasping for air, her motions now a lot faster.

You don't even reply, you're too focused on pleasing her. Suddenly Mara pushes deep into your face and stops dead in her tracks, pinning your head to the bed's headboard, letting out load moans as you feel something warm shooting down your throat. You have **** but to swallow, yet the lack of air makes it difficult and you start ****.

"Just a little longer, Puppy!" Mara pants.

Finally, she lets go, and in a single, swift motion, removes her member from both your throat and mouth.

"Sorry for being so rough in the end, Puppy," she says,"but you were just so good!"
