Rachel moaned softly as I massaged her shoulders out by our pool. Her sexy black bra was undone and under her while I solely wore some swim trunks.
"It's been so long since I had a massage..." she laughed as I oiled her back.
"Well you deserve it," I said as I oiled her huge boobs, "Best Rachel Ever."
Rachel giggled as I oiled and spanked her ass, my cock pushing crudely against the front of my trunks. I then did her sexy smooth legs and feet. However, I couldn't help but go back to her ass, groping the juicy hams before slipping a finger inside.
"That feels so fucking good," she gasped, "a little deeper honey..."
I intensified my probing as Rachel began to moan louder. "Your turn Robby."
I pulled out my finger and she turned over and smiled. "I can't have my baby taking care of me without me returning the favor."
She squirted some oil between her tits as she leaned forward and pulled down my trunks, my shaft nearly slapping her in the face. I looked over her further expanding boobs, even larger with her most recent pregnancy.
I was completely rigid, my head dripping precum into her cleavage. "Oooh..." Rachel cooed as she gave it a lick, "you naughty boy. Getting hard to your mother while you're massaging her."
She grabbed it and began to oil my balls before giving a lick to my head. She then began to suck my balls deeply, making me moan as I reached to grope her big and shining boobs.
My hands squeezed and rubbed the soft orbs before moving to tweak and pinch her hard nipples. Rachel's hot mouth enveloped my cock, slowly sucking it as her boobs swayed slowly.
I felt the urge to cum as she looked up at me, her mouth performing wonders. I lay my head back and prepared to let go when a loud scream pierced the air.
"Isn't that Mom?" I asked Rachel hearing her cry out.
"I believe so," Rachel said as she continued to jerk me off.
I looked up and my heart stopped. Mom stood there, her finger outstretched with a look of untold shock on her face.
"Rachel?!" she screamed, "ROBERT?!?!"
Rachel removed my swollen and throbbing member at her entrance. "Okay Sylvia," She said calmly, "let's be civil."
"Civil my ass!" Mom yelled angrily, the first time I had ever heard her curse, "I wouldn't call it civil with my son's cock down your throat!"
"Don't act like you didn't know," Rachel replied, "I just happen to casually call and invite Robby over even when Oliver isn't there?"
Mom appeared flustered and I noticed her gaze was no longer on Rachel. But on my dick, getting harder as I watched her. "I even remember you telling me about how you watched him shower. Ever since John left."
"Is that true Mom?"
"I... well... THAT'S BESIDES THE POINT!!!" Mom screamed as if trying to shut out our voices.
"How about you come join us Syl?" Rachel asked, "look at this gigantic cock. It needs the attention only a mother can give."
She slowly looked around, watching Rachel continue to suck me off. She then walked over, taking in our fast-paced affair.
"Oh my," Mom replied as she rubbed herself in pace with us, "Robby... certainly has... um... grown." She then turned to look at my full balls hammering against Rachel's ass.
"Don't be embarrassed Sylvia," Rachel said as she watched her reaction, "its common to want to watch your son. Some also love to their son's 14 inches."
"14 inches?!" Mom retorted, "That's impossible..."
Her ability to speak went away as I pulled out of Rachel's mouth, sending her into another violent orgasm as I slowly removed my cock for effect. I was getting even bigger. And Mom was noticing.
"Would you like some of it?" I asked, knowing she couldn't resist.
I could see she was getting turned on even more and I slowly shook my prick and forth watching her eyes follow every move. I ordered her on her knees and she complied as Rachel watched.
Mom then began to suck, her tongue twirling around the head. The sudden feeling of her tight throat almost unbearable but I began to move with her, my balls soon connecting with her chin.
She began to gag and she pulled off, flexing her sore jaw. "I can't believe you are so gigantic!" Mom exclaimed as I looked at her nearly exposed tits.
"Show me those," I ordered Mom, still focusing on my powerful cock above her head.
As if in a trance, she unclasped the red bra and let the juicy wonders spill out. I began to paw and suck them, making her moan.
"Robby is just fascinated with the female body," Rachel said to her, "he just loves all of our sizes and shapes.
Mom's eyes popped open and looked at Rachel. "Don't be surprised honey, I know that look. I used to wear it all the time before I discovered that boy's special talent."
Mom's hands hadn't left my prick, pressed against her stomach with precum dripping onto her navel. Her tits were hard as wood as I continued to suck them, the scented orbs getting me harder and harder.
"Oh fuck!" Mom cried as I sank my teeth into one engorged nipple, "he feels so good!!"
"Yes he does..." Rachel said with a smile as she rubbed her pregnant belly. Mom had me stand as she began to suck my balls, one more than filling her mouth. She then licked up the length of my shaft before smothering it in kisses.
"Lose the pants," I growled as she looked up me and she immediately consented, practically ripping them off in her hurry. I then stood and kissed her neck while mauling her firm ass, making her moan louder as my prick pushed against her panties, the rough cotton feeling spectacular as it rubbed against the head.
I yanked them down, tearing them from her sexy body, her wet displayed prominently. Rachel nodded at me as she massaged the oil into Mom's tits.
At the same time, I pushed into her slowly, making her yell out as she tightened her grip on the pool chair. "Good god! His head feels as big as my fist!"
"Get ready," Rachel chuckled, "he's going to spread you even wider!"
Clenching her teeth, she spread her legs to take 7 inches before beginning to cum. "He's already farther than Douglas has ever gone!" I slid in the rest in one long thrust and began fucking her immediately.
