The day had gone by uneventful. My cousin had come over to hang out for a little while and play video games with me. He lived a few houses down from me, and the rest of our family lived on the other side of town. We were a very close family.
"You boys want to go to the drive in movie with me?" Mom asked as she burst into the room.
Since my dad had walked out on us a year ago, Mom had been very reclusive and moody, so it was quite a surprise to see her so cheerful. She had even dressed up for the occasion. Her lips shined a ruby red color that contrasted very well against her tan skin. She put on a light, almost metallic, blue eye shadow bringing out her light brown eyes, and her wavy dark hair contoured her face in an innocent, but sexy kind of way. My mom, to me anyway, looked very attractive, I always thought when I get married I wanted my wife to look like her. She was very voluptuous, wide hips but not fat by any means, and she was what I considered short around 5'6" or so. Tonight she put on a pair of tight blue jeans that looked like they wanted to burst at every seam. Her loose blouse hung limply on her shoulders showing off her cleavage of her ample breasts and barely hiding much of her stomach. Least to say, I was really caught off guard.
Naturally, just turning eighteen and graduating from high school, going to the movies with your mom was really, really lame. It wasn't like my cousin and I had anything better to do that night, so we reluctantly agreed to go.
We had all piled into the leisure van Dad left us with and mom drove us to the drive in movie that was a few miles away from our house. The van wasn't really that bad. It was almost like a camper. There were curtains for the windows, several radios that had headphone plugs, a small closet, and a bench seat that was shaped like a horseshoe. In the middle of the horseshoe was a table that could lower to make a king size bed in the back. We had taken it out many times when Dad, Mom, and I would go camping.
There was a horror movie playing that night at the drive in, even though mom wasn't a big on horror films, she scared easily, she decided to stay anyway since it was the first time in a long time she had dressed up and gone out anywhere.
"We should close the curtains, and make it really scary," I suggested.
"And put down the table back there and we can all be comfortable," Mom chimed in.
Mom grabbed the speaker that was resting on a metal pole outside next to her. She clipped it to the window, and rolled it up as far as she could. My cousin had shut all the curtains while I pushed the table down and put a cushion on top of it. Mom sat down between my cousin and me just as the movie screen turned black signaling the beginning of the movie.
Mom said in a panicked voice, "I hope this isn't too scary."
"Don't worry mom, I'll protect you from the boogey man," I joked and we all shared a laugh.
No more than fifteen minutes into the movie Mom had already jumped and screamed twice. Her hands were clenched onto my cousin's thigh and my own, so tight it was starting to hurt. I smiled as I watched mom's face as she intently stared at the screen. Every few minutes her eyes would widen, and then shut tightly just like her hand did on my thigh.
Her skin shone from the light of the screen, even in the darkness of the van. My eyes followed the curve of her shoulder, and I could see perfectly down the cleavage of her chest. My cock throbbed at the mental image of Moms melon sized breasts. I closed my eyes for a second, savoring the thought. In no time, my cock had swollen and was pushing down my pant leg. As I opened my eyes, thinking of way to cool down, I noticed my cousin looking at her too. Instantly, I felt the sharp prick of jealousy flood through me. I did not like the look on the face of my cousin.
Mom screamed and jumped again, suddenly. Her hands flew from our thighs and cusped over her mouth. The next second she gasped sharply and her hands grabbed onto our thighs again, this time she grabbed right where my hard cock was hidden. I was caught in a moment of bliss and horror from my mom grabbing my erection. It was my turn to gasp sharply from the surprise of my secret being suddenly revealed. To my relief, it seemed she hadn't noticed at all. Her hand still rested on my cock, but she said or did nothing.
My cousin had rested back on his elbows, making me glad because he wasn't staring at my mom's tits anymore. A few minutes had gone by, my mom's had was still resting on my still hard cock. Without any notice, her hand slowly moved down my leg to my knee, then back up over my cock and to the top of my thighs, repeatedly. Even though my stomach lurched, and the intimidating feeling of the taboo situation I was in with mom swept over me in waves, I was in ecstasy. I knew now that she knew about my stiff cock, and was even playing with it. In front of my cousin no less.
I had a little more courage now, so I slid my hand through her arm and her torso and gently rested it midway down her thigh. Daringly, I rubbed my hand up and down the top of her thigh a few times slowly, matching her rhythm. She spread her legs a little to allow my hand further up. I ran my hand up and down her inner thigh and soon found the warm crotch of my mom. I finally had enough courage to look at her. She was still staring forward at the movie, but every few seconds she stole a glace at me, and then my cousin out of the corner of her eye.
Even though I was rubbing her pussy through her jeans, I still wanted to feel the softness of her breasts. Cautiously, I slid my hand up her shirt and felt the warm skin of her stomach on the back of my hand, as I cupped the bottom of her tit with my fingers. Her hand, in return, grasped my cock harder making it throb. She clenched her hand and released several times, making it seem to pulsate on my stiff rod.
