..."Okay."

"Really?" I ask, the eagerness in my tone surprising myself.

"Yes, I mean, it isn't really any different from me using my hand and helping you get relief as quick as possible should be our priority. Therefore doing what your body wants should theoretically achieve that aim easiest." Before she finishes speaking I am already removing my rock hard penis from under my robes. As it springs up into the open Sister Mary moves towards me so that her chest is positioned directly above my member which twitches in anticipation of what's to come.

Slowly she lowers herself down so my penis slips between the two fleshy orbs. I let out an involuntary gasp as the soft flesh begins enveloping my shaft.

"Oh!" She says suddenly, her torso jumping in surprise causing her chest to ripple and bounce against my penis, sending waves of pleasure and desire through my system.

"What?" I manage to gasp out.

"You just released something from your thing."

"Did.....did I?" I ask looking down at the gap my member has disappeared into. Sure enough as I look a slick, oily substance appears to be dripping around my shaft.

"It doesn't look like the same stuff as last time and I'm definitely not relieved yet."

"Hmm, it appears to be aiding the movement of your thing between my breasts."

"Breasts?"

"Yes that is what they are called." She replies a little bemused. "Sorry, I forgot how limited your knowledge is. Other names include boobs or boobies. I have also read....somewhere....that they are referred to by some unsavoury individuals as 'tits' but I'm not sure if that's a good name for them."

"I see..." I reply committing these names to memory as I refocus my attention back on my insistent member. "Can we please get back to the massage?"

"Oh sorry! Of course we can." Sister Mary pushes her breasts further down my penis until the tip pokes up through the fabric of her habit.

"How does it feel?" She asks.

"A...amazing...." I manage as I marvel at how soft and pillowy her boobs are. "Can you start moving them up and down like you did with your hand let week?"

"Certainly." She says and proceeds to do just as I asked, slowly moving her immense chest around my now giant penis.

Pleasure washes over me like a tidal wave to where I am paralysed in my seat, a **** to the sensations being brought forth by Sister Mary's breasts. Very soon I can feel the familiar building sensation growing within my body as my pulsating rod moves slickly between her large tits. I like the sound of that word in my head for some reason and repeat it within my mind, panting as the building grows bigger and bigger within my crotch. Sister Mary bounces her breasts faster and faster on my lap, the bottoms of her boobs whacking against my thighs and tingling balls.
