Chapter 5: Is This What You Wanted?

Continued from chapter 4:

Despite the sting, she can feel a rush of heat pooling between her thighs, her body responding eagerly to this new sensation.

The second spank falls, and again she counts, her voice growing stronger.

"Two! Spank me! It's my birthday!"

By the third, she's arching into my touch, craving more.

"Three! Spank me! It's my birthday!"

Each word is punctuated by a sharp intake of breath, her nipples visibly hardening beneath the thin fabric of her dress, pressing like pebbles against the black satin.

We get to thirteen. I hold her wrist in place and with my other hand, I take the hem of her skirt and raise it to reveal a large, wide bottom stretching out a pair of shiny, satin, rose-colored underwear briefs with maroon lace trim and matching satin bows. The generous globes of her ass fill the fabric completely, the material pulled taut across her flesh. My cock rockets to attention at this incredible view, straining against the confines of my trousers, as Monica squirms over my lap, obviously embarrassed, but too aroused to care.

Chapter 5:

Just the faintest blush of pink begins to peek out from under the trim of her leg holes, hinting at the tender flesh hidden beneath.

"Thirteen more, Aunt Monica," I say, rubbing her bottom through the thin satin. "Are you ready?"

Monica squirms on my lap, acutely aware of my hardened length pressing insistently against her thigh. The cool air on her exposed bottom sends goosebumps racing across her skin, and she bites her lip to stifle a moan.

"Y-yes, Ero," she breathes, her voice thick with desire, "I'm ready. Give me my birthday spanks."

She wiggles her hips slightly, presenting her barely-covered bottom to me fully.

"Fourteen! Spank me! It's my birthday!" she cries out as the first bare spank lands, the satin of her panties providing little protection.

By fifteen, she's pushing back into my hand, chasing the delicious sting.

"Fifteen! Spank me! It's my birthday!"

Her inner thighs are slick with arousal, the musky scent of her excitement filling the air, growing stronger with each sharp crack of my palm against her waiting flesh.

I pepper Monica's panties with crisp, stinging spanks, coloring her punished skin to match the deep fuchsia hue of the silk. When I pause, she is breathless, squirming, her thighs pressed tightly together as if to trap the heat between them.

"Both hands on the floor, Auntie. I need to check something."

She obeys with a shuddering sigh, bracing her palms against the rug. I spread her trembling legs, and the sight steals away my breath: a dark, wet patch has blossomed across the gusset of her panties, the silk clinging to every swollen contour of her sex. Monica is absolutely drenched, the evidence of her arousal glistening even in the soft light.

"Ummm, Aunt Monica?" I let my fingers trail up the slick mound, teasing the bulge of her puffy labia through the thin, soaked satin. Her clit is rigid, outlined by the taut fabric and **** for contact. I stroke her, gentle and reverent, as if she might shatter from anything more.

She whimpers, hips jerking into my hand, and looks back over her shoulder. Her cheeks are streaked with tears, her eyes wild with lust and with something like shame. "E-Ero... I'm more than okay," she pants, voice ragged with need. "I'm on fire. Please... don't stop. I need you to touch me. Really touch me." Her next words come out as a needy whisper: "I want to feel your fingers inside me, Ero. I want you to make me cum, harder than I ever have before."

She reaches back with one shaking hand and yanks the sodden panties aside, baring herself fully to my hungry gaze. The lips of her pussy are flushed, engorged, glistening with slick that dangles from her gap. "Please... fuck me."

I want to. Desperately. But she's not finished yet. "You have more spankings left," I say, voice hoarse. "You said you wanted to bare not just your skin, but your soul tonight."

I hook my fingers into the waistband of her panties and peel them down over the broad curve of her hips. She gasps as I bare her, every inch of her punished flesh glowing with heat. I let the ruined underwear dangle from her ankle, then slip it away, leaving her naked from the waist down. "Thirteen more, Monica. You know what to do."

She nods, biting her lip, and settles her chest to the floor, arching her battered bottom up for me. "Yes, Ero," she breathes, a tight smile on her face. "I'm ready."

I spank her, hard and sharp, each smack landing directly on her exposed, throbbing flesh. She counts each one aloud, her voice breaking with the effort: "Twenty-seven! Twenty-eight! Uggghhh…Spank me…it’s my…oh my…birthday!" By the time I reach thirty, Monica is sobbing, tears streaming down her cheeks to drip onto the floor. Her pussy clenches and spasms with every blow, flooding my hand with her juices.

"Thirty-nine! Spank me, it's my birthday!" she screams, and the final slap echoes through the room.

I barely have to ask before she spreads her legs wide, presenting herself to me in all her ruined, radiant glory. The lips of her sex are swollen and red, her clit a swollen bead at the apex. The entire slit is soaked and shining, the scent of her arousal so thick it's dizzying.

"Aunt Monica," I whisper, stroking her trembling thigh. "Stand up. I want you completely naked. Then we'll finish your spanking, like you deserve."

She rises from my lap on shaking legs, turning to face me. Her face is streaked with tears, her chest heaving, but there is pride and longing in the way she meets my eyes. With shaking hands, Monica drags the zipper of her dress all the way down. She rolls the straps off her broad shoulders, letting the dress fall to the floor in a pool of black silk. Now she stands before me in nothing but her heels, her mature body trembling and ****, but beautiful beyond words.

She's gorgeous. Her breasts are heavy and full, the nipples dark and stiff, the skin of her belly softly plush. Her pubic mound is a silvered triangle, streaked with the same gray as her hair, the lips of her cunt still flushed from the attention.

"Is this what you wanted, Ero?" she asks softly, voice trembling. Her arms hang at her sides, refusing to cover herself. She lets me look. She wants me to look.
