Twist her nipples as you fuck her tits.

"SO DISOBEDIENT!" you say with a scowl.

You drop the loose end of the belt and instead pinch both of her nipples between your thumbs and fingers.

"Yeeeeeowwwwwwwwwwww!"

Madness takes her. She thrashes against the bindings locking her to the spreader bar beneath her. She attempts to shake the grip of your fingers and her chest rocks violently back and forth. You savor her struggling cleavage around your cock. She tries side to side. She attempts up and down. She thrusts her breasts further out in small circles. Her cries drown out your low chuckle. It is difficult to tell if she is reacting to the pain or pleasure. From the fluids trickling out of her pussy you would guess both.

Like most of your girls, her nipples have been augmented to be extra sensitive. She cringes under the pressure, but knows the worst is yet to come. She fears it, but she really really needs it.

"SAY IT!" you hiss into her ear.

"Master... please punish my tits." she whispers back up at you, "Allow me to restore my honor."

Her face contorts as you twist her nipples in your tight grip. You begin to yank her mammaries up and down your cock.

"AaaRRaAAaaRrrrrAAAaaARrRRrRrrrrrrrgh!" she howls up at you.

You tug her heavy tits up and down your shaft. They slam against her chin and stomach in alternating wet splats under the water of the shower. Your cock is about to explode from the intense friction between her tits squeezed tightly by the belt.

"AAAAAAAAAAAAAAAAAAAAAARG!" you roar.

She cries out in surprise as your grip tightens around her nipples with both of your powerful hands. The tied fat flesh squishes around your 12 inch dick and you begin to cum. Your orange sized balls contract within your stretched scrotem with each violent ejaculation. The streams fire in thick ropes. The blasts stream up her neck and across her face.

You savor each pump over her restrained body. You grunt as more of your semen coats her face, hair, neck, and chest. Even under the stream of the shower it clings to her skin. The augments to your cock cause you to produce enough cum to thoroughly cover her in your precious white substance.

"Ugggghgghgghhhhhh..." Her back goes rigid and she moans out another orgasm. She sobs in relief as you spray her face and chest while torturing her sensitive nipples.

Slowly your climax completes. You relax your grip on her nipples and she falls onto her back exhausted. Her breathing is ragged from both her orgasms and the rough treatment of her engorged breasts. She looks up at you with heavy eyes. She is drenched in cum and quaking in her bindings under the cascading water.

You don't say a word at first. You exit the shower and Alessandra hands you a towel. Once dried you calmly dress yourself and turn back towards the cum covered girl and then your secretary. You've made your decision.
