Caught my Best friend with his MOM.

Never realised my best friend is a literal motherfucker.

I have been friends with him like kindergarten. My family (my single mother and my elder sister) knew his family of 6 members ever since we have met. And never have I suspected him to be having a relationship with his Mom.

This whole thing happened during a summer vacation. We were 15 years old and were playing videogames all day long in his house. He had two younger twin brothers and and an older sister(16). His Mom were a 41 year old milf. I wouldn't say she's hot as hell, but she is and was hot enough to turn faces and make dicks twitch.

And this motherfucker had everything, a PC and an Xbox in his own room, while I slept on the living room couch of my small appartment. His dad is super rich.

We were playing Fortnite and his two brothers were at his aunts house. His sister went out on a date. As he was playing his Mom yelled from downstairs for something. If he didn't run downstairs, we won't be able to play for the rest of the day. So, he quickly gave me the PC and ran. I played 3 games without any success and went downstairs to see why the hell is he taking this long. As I went downstairs, I heard muffled conversation coming from the kitchen. When I approached the kitchen I heard a giggle and a firm no from his Mom. I slowly peeked.

My best friend is hugging his Mom from behind as she cooked and his hands were suspiciously on her breasts. He was basically dry humping her ass and groping her tits through her T-shirt. His right hand slowly went down as he groped her tits with the other. She was okay with everything until then. As he tried to touch her pussy, she grabbed his hand and said "Not now baby".
As she pushed him and turned to face him, she spotted me standing at the kitchen door. I saw her soul leaving her body. Following her look, my bestfriend also turned to find me staring at them.

Both of them looked mortified. I myself was confused and scared. No one said anything for a whole minute. His Mom went back to cooking (pretended to cook). And my bestfriend waited a moment before walking back upstairs. I followed him and confronted him. He just basically started to cry and begged me to keep it a secret, which I agreed to. After he calmed down. He opened up about it. And later I spoke to his Mom.

She was a horny bitch in her youth. She had a body count of 37 guy's until her marriage. It is 68, including me and her three sons, as of now. She met his dad in college and got married to him after two years of 'real', 'honest' and 'faithful' relationship, according to his dad. His dad travels a lot. He had zero clue about her sex life and still has no idea, atleast that's what we think. He is not exactly a naive faithful guy either. He cheated on her with some of his staff.

After she got married, she suppressed her desires at first. But, you can't really tame a wild beast. After she gave birth to her first child, she went on a sexual rampage. She fucked 13 different guys one week and had a gangbang with 6 guys. And when she was 6 months pregnant with my bestfriend, she had a threesome. According to her, even though she liked young boys, she never thought about incest until her son turned a particular age. She started to look at him differently after that. Eventually she gave in to her desires. She gave him a blowjob on his birthday, which turned into a daily ritual. She made him lick her pussy for a mother's day, which also became a daily ritual. In the name of sex education, she made her kids to strip in front of each other and touch each other's privates.

In short she is a great mother.
