Diane's eyes met mine, filled with shame, before turning away to stare at the spring water.
"...beg? You want me to..." She trailed off, her cheeks burning, before forcing the words out. "I... I won't beg."
"Why not?" I murmured, my voice low and teasing. Without waiting for an answer, I gripped my shaft and dragged the thick tip up and down her pussy lips, parting the soft, wet folds with deliberate strokes. The heat of her slit clung to me, her juices coating my skin as I ground against her clit, then back down to nudge her aching hole.
Her body tensed instantly as pleasure began shooting through her. One hand flew to her mouth, fingers pressing against her lips to stifle the sound, but it was no use—a soft, needy moan slipped out anyway. Her thighs quivered around my hips, caught between trying to close and remaining open.
"Look how ready I am for you," I growled, pumping my hips just enough to slide my cock along her slit again, rubbing it against her swollen lips raw.
"I'm so hard just thinking about pounding your neglected pussy. I could fuck you harder than your limp-dicked, old husband ever did. All you have to do is beg for my cock to fill you up.'
She shook her head weakly, but her eyes flickered down to where my tip teased her entrance.
"Didn't you hear?... I won't beg..." She paused, her voice cracking as another glide of my cock made her hips twitch. Then, she continued, "If you want to do it... then do it... don't make me beg for... for aah~"
Her words faltered, and a soft, needy moan left her lips as I pressed harder, the head of my cock catching on her clit and circling it slowly. Her hips tilted upward involuntarily, her pussy lips parting wider, trying to suck me in.
Her body was screaming what her mouth wouldn't admit. She was right on the edge. Her composure wasn't going to last long.
That was my cue.
I reached up and cupped her full breasts, the spring's water making her soft skin slick under my palms. My thumbs brushed against her hardened nipples and I leaned down, taking one in my mouth.
I sucked hard, flicking my tongue over her pebbled tip before grazing it with my teeth. All the while, my hips kept grinding, sliding my cock through her folds, bumping her clit with every pass.
Her back arched violently off the rocky edge of the spring, water splashing around us as her body bowed into my touch. Her fingers dug into my shoulder, her nails pressing against my skin, but she didn't push me away, rather, she held on like she needed something to hold on to. I could see it in the way her her hips tilted, the way lips parted; she was fighting it, but the cracks were showing.
I switched to her other breast, lavishing it with the same treatment—wet, open-mouthed kisses trailing to the nipple before sucking it deep.
But this time, I watched her face, my eyes locked on the way her expression was conflicted. She would soon give in. It wouldn't take long. Just a few more sucking and teasing, a few more grinding against her slit, and her eyes finally met mine—filled with shame and surrender.
"Please...." she whispered, the word barely audible.
I released her nipple with a wet pop, smirking as it glistened with my saliva. "Please what?"
Her gaze dropped, then flicked back up, defeated. "Please... just do it..."
