It all started when my dad brought home an exercise gym set. This thing had all the bells and whistles that must of cost him a small fortune. He told my mom and I who were watching him putting this contraption together.
"We were a couch potato family....but not anymore!...With this new home gym we can all get back into shape!"
I looked at mom and she looked back at me smiling while telling my dad.
"Oh Mike...We are not couch potatoes...are you saying I'm fat?"
Dad stopped what he was doing and got up from his kneeling position and went over to her and gave her a hug and softly stated.
"I'm not saying that...It's just I think our son Mike jr. is 18 now and should be getting himself into shape so that he can impress some of his girlfriends and maybe find the right girl for himself that will make him happy for the rest of his life."
I watched and blushed while I saw dad kiss mom sensuously and grab her ass. Mom rubbed herself against dad's hips and looked over at me while she grabbed dad's ass in a show of affection and smiled saying.
"I'm sure jr. will find somebody whether he lifts weights or not!...He is a fine looking young man."
This made me blush even further and started to make my cock get harder. Dad released my mom and said.
"Mary, this gym set is quite the gadget...Two people can work out at the same time...It will help motivate each other and bring us closer as a family. You'll see."
Dad looked over at me and smiled.
"Jr., I want you to work out everyday after school when you get home.....Mom will work out with you too. And when I get home I will work out with Julie" ( Note: Julie is my sister, who is twenty and attends the local college, but lives at home with us.)
My mom looked at me and agreed with dad's logic and for some strange reason I never saw or realized that she looked very sexy to me. This was causing my cock to rise more and more in my shorts. Mom walked over to me and gave me a hug. I'm sure she felt my hardon when she embraced me and stated.
"I'll make sure all of Jr's muscles get a workout...all his girlfriends will be jealous of how he will look in a couple of months...they won't be able to keep their hands off him.!"
I thought my cock would blast a load of cum right then and there. I shyly broke the embrace between my mom and I felt myself blushing as I made an excuse telling them I had to go to my room and finish my homework. I heard mom and dad chuckle as I bolted for my room. I rushed to my room....not to finish my homework but to take care of my now aching stiff cock. As soon as I got into my room I whipped out my swollen cock and stroked all 7 inches of it with lightning speed thinking of mom's naked body. I saw her only a couple of weeks ago naked when I walked past her room while she was getting to take her shower. My mom has a beautiful body. You could not tell that she was only 38 years old and had given birth to my sister and me. She is a knockout! Even from the short glimpse I got of her breasts she looked hot!...with handful size breasts and huge nipples that looked just right for sucking.
I reached for some tissues on my night stand and quickly brought them up to the underside of my pulsating cock. I looked down at my cock as it started to shoot my cum into the tissues.... pulse after wild pulse deposited more and more of my cum into the already soaked tissues. I was whispering to myself.....
"This cums for you MOM!"
My knees almost gave out as I experienced one of the strongest orgasms I ever felt.
My mind went reeling from the orgasm I just had and thought of working out together with mom!...
"Thanks dad!"
I tossed the cum soaked tissues in the waste basket next to the bed. I finished getting undressed and collapsed on my bed falling asleep quickly thinking of mom.
I woke up in the middle of the night and put my robe on to go take a leak. The house was quiet and as I made my way down the hallway towards the bathroom I saw a dim light coming out from underneath my parents bedroom. I walked as quietly as I could trying not to make any noise. As I approached their shut door I heard them whispering. I couldn't quite make out what they were saying at first, so I placed my left ear to their door and heard mom talking to dad.
".....Our Jr. sure shoots quite a big load!...Look at these cum soaked tissues!...I found them in his wastebasket when I went to checkup on him before turning in."
My heart sank! and my cock was getting hard under my robe making its way out. My right hand found the hot fleshy staff and my mind was racing. Mom found my cum soaked tissues...but she didn't sound like she was upset or mad. I still had my left ear glued to their door as I heard my dad say.
