I found my mother-in-law with her friend

Hello to all, this happened to me a while ago and I'm still excited about what I saw. My mother-in-law has 46 years old, her name is María, and it's worth noting that she's a pretty liberal woman without prejudices, like the kind who goes to a pool and puts on the smallest thong she has and only wears something on top if it's mandatory (she's almost naked). She's a normal-looking woman with a nice face and a nice bum. The other day I went to my girlfriend's place and since we've been together for years, I just walk in without knocking and even have a key, as she's divorced. My mother-in-law has a friend named Claudia who's part of the family since I started dating her daughter. Conclusion: I wrote to my girlfriend to let her know I was coming home from work and she told me to wait a bit because she'd be late. When I open the door to enter, I yell 'María, it's me, Martin', but no one responds. I go to the kitchen to get some water and start hearing loud moans. There are like, come on, suck my ass, keep going! I didn't understand what was happening so I went upstairs to where the rooms are (on the second floor) and there was no one, all the doors were closed, but you could still hear the moaning. When I go back down and look out at the patio, my mother-in-law and Claudia are both balls-deep, my mother-in-law is sucking Claudia's ass who's on her knees on the sofa. I can't even tell you how hard I got in that moment. Then I started jacking off and imagined we'd make a threesome for a hardcore porn video. But it all went wrong. I open the window, making a fool of myself, and say 'oh, oh, sorry, sorry' and both of them turn bright red like a tomato. I couldn't hide that my cock was still hard.

truth to claudia didn't bother her at all that she saw me it's more she sat with open legs and started touching my pussy's hair my mother-in-law tells me please don't tell anything to luz (my girlfriend) i say yes obviously it wasn't my business and i tell them i'm leaving to leave them alone so they'll be quiet because i wasn't going to say anything that wasn't my topic i don't know what else for that i was talking and not stopping looking at claudia's pussy which she practically never stops giving herself a hand then claudia tells my mother-in-law let's keep going and if you want me to look fine we've already seen it look how María is going to explode and besides she's definitely going to go straight to masturbate and laugh and my mother-in-law not very convinced says but you're sick it's luz's boyfriend!!! half angry covering her face with a pillow claudia keeps going and says give maría a break let's stop looking anymore and started giving her kisses on the neck and touching her breasts i automatically started touching my cock through my pants and they told me sit down there and do your thing and that's how it was they kept fucking and i sat down on a bench to masturbate watching them suck each other's pussy and ass i got up and wanted to suck claudia's toe to see if i could advance because she was sucking maría's ogete and then she told me just look nene you're luz's boyfriend and that's how i kept masturbating for 3 times looking at that lesbian scene and until this day i still get off thinking about what i saw greetings everyone !!after that i'll tell you other times when i saw her doing topless or the time we arrived with luz and she was giving herself a hand in the kitchen
