I took a few deep breathes, still having half my cock buried in her tight anus. Once I had control again, I lifted a knee and placed the foot to her side. I reached out with my hands and managed to get a good enough grip on her shoulders from the back, despite my hands being slick with butter.
I felt Aunt Sheen stiffen her shoulders as she understood what was coming next.
Aunt Sheen had her face buried in a pillow and her hands shivered as she struggled with the pain and the effort to keep her huge and heavy ass cheeks apart. I leaned over her back, with a firm grip on her shoulders I pushed down on her lower back. This caused her to push out her lovely and large ass even more towards me.
With a strong jerk I pushed in another inch of my cock and heard Aunt Sheen begin to sob. I could imagine it as her tight rectum stretched wide as my thick cock penetrated in her virgin asshole.
I knew I wouldn’t last too long with the immensely tight grip of her rectum and I hurriedly gave little jerks and kept pushing my cock all the way in.
“Uuunnhhh!” Aunt Sheen cried aloud as I finally buried the thick shaft of my huge cock all the way in her tight asshole.
I took a deep breath and pulled out my cock slowly.
“ooohh.. ” Aunt Sheen moaned and exhaled at the same time as she felt her rectum trying to return to normal when I slid my cock out.
“Ooowww! Ooww! Oooww!” Aunt Sheen began to groan loudly as I slammed my cock all the way in without warning. I continued to thrust my thick and slippery cock deeper into her tight asshole with each jerk. I had a firm grip over her shoulders and Aunt Sheen was gripping my foot at her side. I felt her nails dig in my leg as my thrusts kept getting faster.
I couldn’t get more than half my huge cock in her little anus so I kept thrusting it as far as it would go and heard Aunt Sheen moan and groan with every jerk.
Within a couple of minutes I felt my orgasm build up deep in my heavy balls. The head of my cock had engorged to enormous size with the rush of blood into it. It was one of the most exciting moments of my life as I pushed my cock deep in Aunt Sheen’s slippery and tight asshole and lay on her.
“Aaahhh!” I groaned loudly as I felt the thick streams of cum spurt out of my cock deep within her tight ass. Aunt Sheen was quivering with the effort and her soft ass cheeks were now softly rubbing against my balls. The sensation was so euphoric that I closed my eyes and lay on Aunt Sheen’s back.
After about a minute of my lying on her back with my cock now dripping drops of cum in her ass Aunt Sheen finally found the strength to move and I eventually rolled over to the side.
“Aaah! Ow!” Aunt Sheen groaned through gritted teeth as my now flaccid cock plopped out of her slick and messy asshole.
“Oh!” I suddenly exclaimed and popped open my eyes from the reverie of after-orgasm as I felt something warm on my wet and slick cock. I looked down and my eyes flew open in shock as I saw Aunt Sheen bent over my cock, licking the gooey mix of butter and my cum from it. She really looked excited to lick my cum-streaked cock and I spread my legs wider as she tried to reach lower with her mouth.
