I immediately withdrew my cock from her mouth, scared that she might pass out.
“Aack.. ghagh.. aahh” gasped Aunt Sheen and gripped my thighs with her hands for support.
“This time you’re going to put your cock all the way in, son, understood?” said Aunt Sheen as soon as she had caught her breath.
“But I’m scared you might pass out, Aunt.” I said, voicing my concern.
“No, I won’t. All you have to do is be more forceful, all right?” she replied.
I nodded my head and again took position in front of her. Aunt Sheen opened her mouth wide and engulfed 3 inches of my cock and waited. This time I caught her face in my hands, with my palms covering her ears. I began to stroke my throbbing cock in and out of her wet mouth. Aunt Sheen co-operated by stretching her tongue all the way out. I could feel her outstretched tongue getting the shaft of my cock wet lower than her lips had reached.
I then pushed my cock as deep as I could.
“Aacckk!.. Aarkk!.. aaaa.” gagged Aunt Sheen but I pushed in ever deeper. This time I felt the huge head of my cock reach all the way to her throat. Aunt Sheen was now gagging hard now but this made her throat contract even tighter around the head of my cock.
I pulled out the length of my cock from her mouth, letting the head remain in. I could see Aunt Sheen’s eyes were closed but a steady stream of tears was flowing from the sides. I also saw a strand of spittle steadily drip down to her huge boobs which were now crushed with my thighs.
I let her catch her breath for a few moments before I felt her hands reach around and grab my butt cheeks. Aunt Sheen pulled my crotch closer to her, gulping in over half of my cock this time without much effort.
It had been over 10 minutes since Aunt Sheen had started to tease my cock and now I could feel my orgasm getting closer.
I grabbed a fistful of hair from the back and pushed in my cock deeper and deeper inside her wet, warm mouth. I began to stroke my cock a couple of inches out before pushing it harder and deeper while stroking in.
As my orgasm built to its climax I could feel the head of cock become even larger and my balls became warmer with excitement.
I could hardly control myself as I pushed my cock in for the final stroke and rammed it a little too hard. As soon as I felt my throbbing, huge cock go to Aunt Sheen’s throat I felt myself climaxing.
“Aaarrrggh… Aaahh.. aaahhh…!” I growled and moaned deeply as spurts after spurts of hot, sticky cum was released down Aunt Sheen’s gagging throat. Aunt Sheen couldn’t take anymore and was struggling to get the thick, throbbing, cumming cock out of her mouth but I didn’t seem to realize how hard my grip on her hair was, preventing her from moving her face more than an inch to each side.
After around 10 seconds of cumming hard in her mouth I finally let go of Aunt Sheen’s hair and staggered a couple of steps back, still unable to open my eyes in the euphoria of after-orgasm.
“Aaaack.. huh huh huh!” I heard Aunt Sheen gag and sputter as she struggled to catch her breath and decide whether to swallow or spit the thick cum which seemed to have filled her throat and mouth and streaked down from her lips to the ground.
