There was somthing about pregnant women that just made my cum boil within my nuts. So much so that even my own mother, now eight months pregnant, was feuling my fantasies. As an 18 year old, I was wanking to thoughts of my mother long before my dad knocked her up. Now, with her large, swollen tummy, it was almost too much. My mother always reminded me of the actress Andy MacDowell, except my mothers boobs were much bigger. I couldn't help but marvel at how much larger they had gotten since her pregnancy. They seemed to have a life of their own, rocking, almost as if in slow motion, under the light sun dresses she wore. God knows what they must do when freed from the confines of her enormous maternity bras. So here I was on a Saturday afternoon secretly watching my mother as she sat on the livingroom sofa. Her and my lucky bitch of a sister-in-law where giggling like school girls as they felt the baby kick within moms massive tummy. As my brother's wife listened for the unborn baby's heartbeat, mom looked over and caught me staring. My eyes quickly went from mom's tits to her eyes and she gave me a warm smile.
"Sweetie, why don't you come feel your little sister kicking." She said.
I froze. This was the first time I had recieved such an invitation and I could already feel the blood rushing to my cock.
"Uh... Okay, I guess." It was all I could mutter.
As I moved to the couch, my sister-in-law got up and said she was going to check on my dad and brother, who were outside.
Mom patted the cushon next to her invitingly.
I sat down and emmediately, a surge of intimidation ran through me. Here I was, inches from such a beautiful, experienced matronly figure. Her long legs and sexy feet, gigantic boobs resting on a belly that looked like it could pop anytime - it was all too much. I jumped to my feet.
"I...I need to go." Was all I could say.
She watched me scramble up the stairs and called after me in concern.
"Sweetie?"
I ran to my room and lay on my bead. My cock was throbbing in my pants. Just as I was regaining my composure, there came a gentle tap at my door. My mother poked her head in.
"Josh, can we talk?" She asked.
