Winning at mom's game

Later that night I sat outside near the pool. I had finally figured out that mom hadn't been fucked in 40 years. No wonder get pussy was so tight.
I had a nice buz from great fuck session with my mom and a 6 pack of beer.
I laid on the chaise just enjoying the distant thunder when I heard the door open. I looked over and saw mom walking towards me.
As she stood next to my chaise I saw that she was wearing her robe. She landed over and kissed me. Her lips and the way our tongue danced made my cock begin to get hard. I moved my hand to her bare fat knee and slowly moved my fingers higher kneading her fat rolls as I went.
Mom moaned into our kiss which only gave my the green light to keep going.
Once my fingers brushed against mom's pussy hair she broke our kiss and whispered "let's go inside baby boy. Dad could be home any second".
I slid my fingers between her pussy lips and whispered "no mommy. I want to fuck you out here. "
I began to slide my finger in and out of her pussy. My thumb rubbed across her clit.
Mom whispered breathlessly " baby boy, please let's go inside and you can fuck mommy in the house"
I shook my head no.
Feeling mom's pussy getting wetter by the second and the sloppy sounds I knew she was enjoying my touch.
Mom moved her and released the belt holding her robe closed. This allowed her fat saggy tits to hang free. Her areolas looked even more bruised and marked as she grabbed one tit and rubbed the nipple across my lips. "Come on baby. Suck mommy's tittie baby"
I opened my mouth and I licked her nipple, but didn't suck it.
Mom reached out and grabbed the top of the chair as I worked my fingers in her pussy finger fucking her fat gspot. Mom moaned out "please baby please"
I increased the speed of my fingers feeling her pussy juice squirting down my hand and dripping off my elbow.
At the moment mom was struggling to stand from her full body orgasm I saw the headlights of dad truck.
Mom froze by I did not. I kept working my fingers
"baby baby baby son, stop baby please stop your dad is home. This is destroy our family" Mom pleaded. I didn't say anything but worked my fingers even faster. Her pussy began to squirt again. He pussy was throbbing and her clit was rock hard.
I whispered "be quiet mom. We don't want dad to know I've got my fingers shoved in your pussy and I'm going to give you the baby you want"
Dad turned his truck off and mom gathered her robe with one hand to attempt to hide her nakedness. He other hand was trying to keep her from falling as her knees as shaking from her insane orgasms that her son is giving her.
"Baby please" she moaned.
I threw my hand up and yelled "her dad what's?"
Mom squeezed her eyes shut and I added another finger into her pussy.
"Hey son, yall enjoying the night?" Dad yells back.
"Yes sir, you wanna join us?" I yelled at him.
"Nah, not tonight son.... mama you not gonna speak? Dad asked as he stood at the back door about 10 feet from mom and I.
"Hey honey, I'm sorry.... I was just focused....on trying to figure out the night ....bird we hear" Mom muffled through broken sentences.
"Yeah I've never cared for figuring it out. I'll see ya in bed in a bit" Dad replied to mom and he opened the door and went in.
As the door closed I pulled mom by her arm causing her to step on the chaise to keep from falling over. I moved my fingers from her pussy to her now exposed tit. I smeared her pussy juice on her nipples.
I sucked each nipple in my mouth. I licked and sucked and bit her tits.
I felt like a frenzied drunkenly fool. I didn't care.
When I took my mouth off one nipple I grabbed it with my fingers and pulled and twisted it.
Mom was now standing straddled me with her hands on the top of the chaise.
I moved one hand and pulled my cock out of my shorts.
I thrusted my hips up feeling my cock splitting her pussy.
Mom sat down sinking onto my very hard cock.
I grabbed her hips and ground her onto my cock.
Mom moaned as her pussy stretched over my cock.
I thrusted my hips as I pulled her down.
"Fuck yeah mom. Let your son breed you mom" I groaned.
"Baby boy, you make mommy feel so good. This is dangerous baby. Your dad can see us" she pleaded.
"Let him mom. You're mine now" I growled as I pulled her down harder onto my cock.
"Baby mommy loves you baby boy" mom moaned as her pussy began to throb and milk my cock.
I leaned forward kissing and licking my mind neck and chest. Bitting her at will.
Mom's pussy gushed around my cock. She bounced up and down on my cock as I pulled her down harder and harder with each thrust.
"Mom I'm gonna hurt you. I'm going push into your cervix. Tonight I will give you our child" I spoke in between kisses and bites.
"Baby your dad. Please baby. Funny do this" Mom begged.
This cause rage to build inside me. I was angry that mom didn't want to hurt dad after 40 years of him hurting her.
I pushed her back onto the foot of the chaise. I jumped on top of her spreading her legs wide and lining them with my weight.
"You're mine mom. You're mine now. You're gonna be bred tonight. I'm going to give you our baby" I hissed as I began to plunge my cock deep and hard.
I felt he cervix against the head of my cock.
"Take it mommy. Take your sons cum. Take my seed mommy" I hissed again pounding so hard I am surprised at myself.
" baby don't.... baby stop.... baby don't stop. I'm cumming baby I'm coming" mom moaned as he pussy thrived tighter as I pushed my cock thrive her cervix. I felt the pop as moms womb was now opened and getting streams of my cum.
"Baby baby baby baby fuck fuck fuck fuck"mom chanted as she came hard around my cock.
Mom sat down completely on my cock. She leaned and placed her head on my chest. My arms wrapped arms he. We were both panting and sweating.
After a few minutes my cock slid out of her cervix. I felt a river of her pussy juice and my cum running out of her well fucked pussy.
" tonight was the night mommy. I made you pregnant. Your son bred you and I loved it" I whispered.
Mom pushed up on trembi arms and kissed me.
The light in the kitchen just came on......
