This is one of those confessions that I need to get off my chest.

About ten years ago, I was a sophomore in college out of state. I would normally come home during holidays and the summer break to see my parents. My mum's birthday is in mid-May so I thought I would surprise her with a quick visit over the weekend.

She had divorced my dad a year before. It was amicable and, with me being older and in school, it didn't affect me much. I still saw and spoke to him often. The only thing that it didn't really change was seeing him at the house.

It was a late Friday night when I arrived. Most of the lights were off. I didn't want to scare her so I went in quietly through the side door. I figured I would head to bed and get up early to cook a birthday breakfast.

There was just enough light from a couple of lit rooms plus the full moon to avoid having to turn on any switches.

Our house is a decent size so after coming in the side where the laundry room is, I walked down the hallway and opened the door to the main house. I made sure to open it slowly as to not make any noise.

As I moved into the TV room, I heard some muffled sounds coming from the back of the house towards the living room. Curious, I tiptoed towards the sounds that started to get louder. It clearly sounded feminine in origin, and I wondered what my mother was doing.

Not making a sound, I peeked my head around the entrance to the living room.

My heart stopped.

My stomach sank.

Bent over the couch was my naked mother and our neighbor, TJ, from down the street. TJ was a massive man, standing well over six feet with dark body hair all over him. He was a "bear" in every sense of the word with shoulder length hair and a thick long beard.

They were at an angle to me so I had a clear view of this giant man fucking my mum from behind. He had his massive paws on her hips and with each thrust, I could see her ass ripple as he pushed deeper into her. TJ then smacked her ass and my mother moaned with her head buried in the back of the couch.

My cock betrayed me by engourging with blood.

"You like that dick?!" TJ barreled out.

"OH GOD YES!!!" my mother responded as she clinched up and I witnessed her start to climax. TJ picked up the pace and I watched as his fucking was pushing her petite body around like a rag doll. She bucked back against his large body and she came hard on our neighbor's cock.

I felt tremendous guilt watching them, especially with one of the hardest erections I ever had. Fortunately, I was in the dark room and I knew they couldn't see me.

As my mum settled down from her orgasm, TJ pulled out and ordered, "Clean my dick." I watched stunned, as he removed one of the largest cocks I've ever seen out of my mother's vagina. He could have been in porn. It matched the size of his body and she wasted no time in assuming a kneeling position to execute on his order. From this angle, it was the first time I saw my mother naked. She had large breasts with dark, long nipples. Her older body was only a little saggy and I couldn't believe she had no pussy hair. I wondered if she waxed herself or had someone else groom her. My dick twitched knowing she probably did it to enhance TJ's sexual desire.

In a split second, I watched my mother lick and clean her juices off of TJ enormous penis. As she did this dirty deed, her right hand slipped down and she fingered herself while providing oral sex to our neighbor.

With continued guilt, my hand found my hard dick in my sweatpants. Shamefully, I undid the string tie for better access, and I went right for my cock as I watched my mother suck and masturbate.

"You like worshiping my big cock?" TJ asked in a booming voice.

"I love your big cock. I love you fucking me with your big cock," my mother responded in between licking the head of his penis and balls, all while rubbing her clit and pushing several fingers into her pussy.

TJ clearly liked to be in charge and dominant. My mother clearly liked to be submissive and his slut. I clearly liked being a perv.

After a few minutes, he pulled her up and then took a seat. "Ride this dick until I cum," he said forcefully. My mum grabbed his cock. Her fingers not even touching as she gripped the large penis. She straddled his big body, and I watched as my mother slowly sank down on him, taking it almost down to the base. It looked like he had bottomed out at my mother's cervix which immediately caused her to cum once again. TJ grabbed and mauled at my mum's tits while she rocked her hips on his massive tool. She wasn't even bouncing up and down yet. She was just grinding the full length of his cock against every part of her womb.

My mother must have cum for almost a minute. When she had recovered, I watched as she lifted up and more of TJ's cock came into view. Her pussy lips were pulled out while sliding up. My mum's asshole was on display until TJ lewdly pushed one of his fat fingers in her back door. "YES! YES! FUCK MY ASS!" shouted my mother. His finger went in deeper.

This was too much for me and I started to cum. And, cum hard. Fortunately, I had my underwear and pants on as I shot so much sperm that no single tissue could have held it all. Ejaculating to this sinful sex scene brought all sorts of emotions but to my surprise, my cock remained hard as they continued to fuck in front of me.

TJ was building up himself as my mum continued to ride his dick. He removed his finger from her ass and started sucking on the tits that had nursed me. He started to grunt and fuck her harder as he erupted inside my mother's pussy. Her body rode him like a bucking bronco and she came one final time with her lover.

I pulled my wet pants down and continued to jerk off while they both orgasmed in front of me.

My mother finally pulled up and off of TJ and, without being prompted, started to clean his cock again. When she dismounted, my mother got on all fours with her ass towards me. I had a front seat view of my mum's open and stretched pussy. Her hole was huge. TJ's cum erotically oozed out. The first amount of cum dropped out lewdly onto the carpet while the rest started to slid down her thighs.

This was again too much for me, and surprisingly I shot my cum. I should have tried to catch it but I ended up blasting onto the wall. I desperately tried to wipe it off the wall but knew I had to try and clean it in the morning.

Embarrassed, confused, and ashamed, I pulled my pants up while my mother continued servicing her well endowed lover. I slipped back view and reversed my path back to my car while they were still preoccupied.

I drove around town and found a cheap hotel to spend the night. I figured I was here so I would call in the morning to visit my mother on her birthday. No more surprise visits for me!
Needless to say, I spent most of the night jerking off remembering the first live sex scene I had ever witnessed. I just wish it wasn't my mother and our neighbor...
