My palm was feeling warm now. I took a step back and bent low from the waist. My face was now a foot away from Aunt Sheen’s huge, naked buttocks. Her knees were spread a couple of feet apart. I could see the small beads of sweat on her crotch. The sweat began to make its way from her back down to the deep, dark butt crack. I stood straight again and turned to stand sideways behind her. I put my left hand on her lower back and pushed down. Aunt Sheen managed to push her back even lower. This made her lovely, dark buttocks to jut out even more prominently.
THWACK! THWACK…
I began to spank her ass again and again. I felt her soft, huge buttocks ripple noticeable every time my palm slammed into them.
“Aaahh! Oowww! Oowww! Ooohh!..” Aunt Sheen continued moaning and groaning loudly but managed to keep her voice low. I didn’t seem to be able to stop as my right hand went on going up before smashing down hard on Aunt Sheen’s luscious, large ass cheeks. I could see my palm beginning to leave clear marks on the dusky buttocks but couldn’t feel a thing at the moment.
All I could focus on was the way Aunt Sheen’s huge, lovely ass cheeks wobbled and rippled as my hand smacked into them hard again and again. I noticed my cock was now hardening. I pushed it against her soft, curvy hip and welcomed the warmth of her skin.
“Unnggh! Unnhh! Oooh! Oh! Oh!” Aunt Sheen’s groans were becoming shorter as my hand began spanking her faster and faster. I don’t remember how many times I had spanked her then but I finally stopped I heard Aunt Sheen yell out my name.
“Ali! Oh, son!”, Aunt Sheen half-sobbed and squirmed, being unable to move away.
It was only when I heard her take my name (which was the safe-word) that I immediately stopped and took a step back.
“Whoo!” I exhaled loudly and stood panting behind her. I looked down at her enormous ass cheeks and was shocked to see a few clear palm-prints on Aunt Sheen’s enormous buttocks. Aunt Sheen’s body was trembling slightly but she didn’t utter a word. I could see that she was taking long, deep breaths. It was an effort to overcome the stinging pain she was feeling in her behind. Aunt Sheen’s lovely dark body was soaked with sweat by now. The streaks of sunlight pushing through the grille of the balcony wall shone in bright spots on her sweaty, dark skin.
It was then that I looked down and noticed my palm was bright red. Soon, I felt the significant stinging sensation on my palm. I realized I had spanked Aunt Sheen with quite some force to leave visible marks of my hand on her dark-skinned ass. However, I was glad I had stopped as soon as I heard her say the safe-word.
A minute passed by and I caught my breath. Standing straight up I stepped behind her once again.
“Shhh! Oh, God! That stings!” Aunt Sheen hissed and grunted through her teeth as I gently brushed my palms across the width of her enormous ass cheeks.
I knelt down on one knee and immediately noticed the whitish cunt juice that circled Aunt Sheen’s thick, dark pussy lips. I smiled when I realized that Aunt Sheen was aroused. I remember being surprised at this. I had not seen anyone becoming aroused despite being in obvious pain. I understood later that this was part of the attraction for submissive people.
