No, her to do it herself, this is her sin

I took out a small key and opened one of her manacles. Her hand shot down towards her sopping, waiting cunt but I caught it and held it firm.

“Confess!” I practically shouted at her, releasing her hand.

“I WANT TO CUM!” She shouted, her shout turning into a scream as the first orgasm of her young life ripped through her body like a locomotive. She screamed again and again in pleasure as she practically tore at her cunt with her hand, thrashing against the chair as I held her to make sure she didn’t hurt herself. I held her carefully , eventually pulling her hand away, allowing her body to shudder and finally relax.

I re-tightened her cuffs and turned her back around.

She turned around and gave me a questioning look but it seemed like she was still unable to speak.

“That was only ten,” I explained solemnly, “I believe the punishment is forty.”

“P-please,” she swallowed, wiggling her hands to try and get free. I raised an eyebrow, seeing what she was asking. “It-it’s still burning.”

I nodded, “very well.” I unclasped her restraints and then, removed her nipple-clamps, “she whined at this and I frowned at her, "do it yourself. That was just to show you how good it could feel, do you understand?” She nodded eagerly, shame washing over her face but was quickly replaced by need. She couldn’t help herself. Her young body had needs and she had no experience in resisting them.

I pulled over a stool and bent her over it.

WHACK

I delivered the eleventh slap and her hands went to work. I watched with fascination as this complete virgin began to work her pussy with one hand and her breasts with the other like a trained whore. Her mind simply taking her fingers where it knew they were instinctually needed. Her fingers pinched and pulled at her sore nipples as she moaned. Her other hand rubbed at her sodden slit and eventually she found out there was a spot where it felt better. Her back arched as I delivered whacks 12-20 and she found her clitoris for the first time, even if she didn’t realize what it was.

Her second orgasm was nearly as powerful as her first, but I didn’t relent and quickly drove down with whacks 21-40 in rapid succession. She didn’t relent either and rode out orgasm after orgasm for several minutes even after I stopped.
