My atonement session was about to start. Sister Theresa sat on a wide chair and invited me to lay on her lap, naked, head to her left and bottom to her right. I willingly did. She leaned her heavy breasts on my back. They were soft and warm, and I could feel her hard nipples piercing through her dress. It was a position that ensured I would not be able to escape once my derriere started to burn.
Sister Victoria took her seat on a couch opposite us, a great spectator position. Sister Theresa asked Sister Maria to stay close, apparently, she had some plans for her. Just in front of me there was a big mirror on the wall, so I could see everything that happened behind.
The spectators did not remove their eyes from my hard dick, hanging below like a ox before jumping on a cow.
I prepared myself for an awful stroke by the mighty paddle, but Sister Theresa did not rush anywhere. She continued to caress my ass, expanded to my back and legs, making the touch more and more sensual. Occasionally she would flutter my anus, generating electrical currents that reminded me the treatment of Sister Victoria. Her face, as I saw in the mirror, looked like she was in meditation.
Suddenly she raised up her right hand and slapped my butt strongly. A very nice teaser. Few more and it started to hurt. I looked in the mirror to see when she would take the paddle. I don't know how I missed it, probably I closed my eyes from pleasure, but I jumped when I heard the ringing noise and felt the awesome thump. I opened my eyes to see in the mirror the second thwack hitting its target.
The sweet mix of sharp pain and fierce stimulation started to spread through my body. I prepared myself for the hell to follow, wondering what would happen first - I would faint from the pain, or ejaculate from the stimulation.
But then Sister Theresa turned to Sister Maria, who looked ecstatic, with the paddle in her hand. "Sister Maria," she said, "now it's your turn, but please have mercy on the gentleman, we need to atone him, not to kill him."
"Thank you, Sister Theresa," said the young nun, "I will do my best."
She stood to the right of Sister Theresa, in a position that had excellent access to my bottom, without eclipsing the vision of Sister Victoria who was sitting opposite. She held the paddle in her right hand and started to spank, first hesitantly, then with more and more excitement and vigor.
The fragile young nun did not have much power, but she gave all she had, and, hell, that was painful. I looked in the mirror in front, and the incredible vision made me forget the pain completely. The girlish, innocent, nun was in a total sexual ecstasy. Her face and neck were red. With each whip, her body twisted, and she emitted a sharp moan as if a monster cock was throbbing into her tight, virgin, vagina. As she continued, the moans turned to screams. She was on the verge of a gigantic orgasm, apparently the first in her life.
The vision of the beautiful young lady on the brink of erotic big bang, got everybody in the room out of control. The first was sister Theresa. Leaning on me with her big breasts throughout the session, she now unzipped her dress and pulled its upper part down to her waist, undid the buckle of her bra, and dropped it on the floor. Rubbing my back with her dark and wide nipples that protruded from her huge tits, she slid her hand under my body, and grabbed my bouncing cock. She wrapped it gently but firmly, so that every thwack of the paddle pushed my cock in and out of her palm.
I shifted my eyes from the mirror to look at Sister Victoria. She was in a complete state of madness. She was still sitting on the couch, her dress pulled up to her waist, her panties on the floor, her feet on the couch, her legs spread to fully expose her bushy vagina, which she masturbated in frenzy. When she realized that I was staring at her shockingly, she got even more excited. She pulled apart her labia to give me a clear view of her clit, red and swollen like a small, erected penis. Her fingers alternated between sticking into the wet slot to pump the lubricant, then using it to massage the clit vigorously.
I started to think that all this was a grand hallucination, when Sister Maria's crash cut my thoughts. She let out a blood-curdling shriek, dropped the paddle, and collapsed onto the floor. When she writhed and squirmed, a blend of ecstatic cries and laughter filled the room. She appeared blissful for the pleasure she had experienced, laden with guilt for the sin she had committed, and confused about what had happened to her and whether she should feel exhilaration or agony.
