Not too hard - she's new to this, after all

Your latest act of self-indulgence is met with a more insistent "MMMMMPPPH!!!" than before, but you're quick to soothe her with a caress of the cheek and a few choice words of reassurance.

"Relax, relax... I won't go deep. Now, suck it - try some stuff with your tongue."

The girl's cheeks do concave at your command, though you catch her eyes flashing in a subtle show of defiance.

"Hey. You're doing great, by the way. We'll have that perfect grade in no time."

This seems to placate her somewhat, for she goes on to curl her tongue beneath your waiting tip. Then she subjects the foremost portion of your meat to a thorough bout of saliva-soaked suckling, gazing patiently up at you from beneath her mask of messy make-up all the while.

"Fffuck, girl... You're gettin' me...!"

The sensation is too exquisite to resist. Your head thrums with blood and electricity, hips working of their own volition, and before long you're probing the deepest, wettest region of her oral cavity. You manage to hold off on violating the sanctity of her throat, though, and your Love Doll shows her appreciation by lavishing as much sloppy oral affection upon the stretch of member occupying her mouth as possible.

*Pops* of roiling mouth-pressure soon give way to *peeps* of stunned acquiescence when her plush red lips finally succeed in milking you of your seed. You fire off each slippery ribbon without warning or remorse, and to her credit she takes the load like a pornstar. You're able to pull out with nary a cough from your Love Doll - of course, given that she isn't technically breathing, perhaps such a thing should be expected.

"Fucking incredible..." you huff, making your approval obvious. Harley doesn't exactly light up at the sound of your praise, but she does manage a shy, strained smile between attempts to wipe the remaining fluids from her lips and face.

"Glad you liked it... Because that wasn't my favourite thing in the world, I'm not gonna lie."

The giggle that follows seems odd, given the negativity of her take on the experience.

"...But it was fun to see you react like that at the end, at least." she concludes. "I think I can do better next time."

Her continued compliance cows you into a kind of awed silence (and reignites a dim fire in your loins), but the ensuing ache of overuse pulsing deep within your johnson tells you everything you need to know about what the next few hours would hold.
