..."AHHH!"

It's not me that yells this but Sister Mary! As she does her whole body begins to shudder and tremble as a surge of hot liquid cascades from between her legs. "Oh my....!!" She screams as I don't relent in my humping, the fresh sweet nectar now coating her inner thighs easing my movements even more. "That felt so....good..." She breathes hoarsely whilst I continue to hold off my ever nearing end for a few moments more.

"You enjoyed that?....*pant*....my dick between your legs....*pant*....whilst I touch your breasts?!" I say, dark pleasure rippling through me as the words escape my mouth and I give the two hard pebbles another firm pinch.

"Uh....no!...I mean...." She splutters as a few less violent shudders still move through her body. "We must.....stop.....this is too.....ah....too much!"

"No way!" I yell. "I've still got to empty my balls!!"

"Please.....stop...quoting that.....letter!" She says although I can feel her quivering pleasure as well as hear it in her voice.

"I think you....*pant*....like it....*pant*....when I say these things!"

"No...I.."

"Why else did you....*pant*....keep that letter if you....*pant*...didn't want to keep reading those words..." I say, smirking darkly at Sister Mary, my face on her shoulder.

"I....ah....would never..."

"Maybe Stephen was right and you are a little slutty!" As I say this Sister Mary's body gives another intense shudder.

"Nooooooh....ahhh!" She screams as my dick is doused again in more juice! Unable to contain my climax for much longer I focus my attention back on squeezing her tits and humping her thighs. Seconds later my cock begins to convulse as my pleasure begins to peak!

"ARGH! YOU HOLY WHORE!!!" I scream, quoting the letter one last time as I thrust to my full extent between her legs and squeeze her tits with all my might. Accompanying this motion is an almighty spurt of hot ejaculate flying across the room to splatter against the wall.

"Oh...!" Exclaims Sister Mary as my dick continues to spasm between her wetness firing an almost continuous stream of thick cum from its tip, coating the wall and side table. The jug of water crashes to the floor as a glob of sperm smacks into it, the clear liquid joining the white pooling on the ground as my cock continues it's merciless barrage, covering books, furniture and brickwork in equal measure. "How is there so much...?" Sister Mary asks as I continue cumming, albeit less violently than my initial onslaught. As I finally near the end I pull my cock back between her slick leg meat and shoot a final few spurts onto her ass!

After the most intense sensation of my life so far I stagger backwards and collapse back into the familiar chair. Sister Mary remains standing where I left her, still breathing slightly heavier than usual, staring at the buckets of cum running over the wall, furniture and floor. "Amazing..." I hear her say, although whether referring to my cumplosion or her own strange vibrations I cannot tell. I manage to raise my head to look at her. She still hasn't moved, nor has she lowered her skirt back down allowing me to see her freshly glazed buttocks.

Feeling completely drained I can't even appreciate the gratification of such a sight and it only causes my still pulsating cock to make a small throb of acknowledgement. Whilst I continue to recover myself Sister Mary continues to gaze at the white film covering a sizeable part of her room.

"You really did need that didn't you..." She says in awe, looking over her shoulder at me. I manage to give a small nod in response. "That felt.....different..." She continues her hand drifting down to her groin and touching the clear, wet liquid still dripping from the area. As her fingers scoop up some of the fluid she shudders again and a small moan escapes her mouth. "Oh! Excuse me..." She says, a small pink flush creeping into her cheeks. "Where did this come from? Surely not my..." These thoughts clearly lead her to some discovery. I can tell because I see her eyes widen and she gives a small start, as if snapping out of some sort of daze. She turns back to face me.

"You....I mean...we shouldn't have done that. We shouldn't have done any of this!" She says, her expression one of severe anguish. I'm still too weak to respond verbally and in any case I am more focused on how sticky the front of her thighs are.

Noticing this she quickly pulls her skirt down over her thighs. Annoyed at the loss of her legs I give her a frustrated look but she doesn't appear to see this. "I should never have thought I could handle this. I should have taken your problems to the elders before trying to help but I wanted to prove myself..." She says before burying her face in her hands. "What am I going to do? I'll be thrown out in disgrace, never able to serve again...". Having regained some of my strength whilst she spoke all this to the room I feel up to articulating a sentence, but what to say? I don't feel any guilt over what just happened but clearly Sister Mary does. After a few seconds whilst I mull over my words and Sister Mary begins to gently sob I sit up and face the grieving nun.
