Mom and cousin secret sex

First off I’d like to say my mom is 48 years old. She has great breasts, big, somewhat saggy. It looks good, not nasty like some saggy breasts. She has a long nose and long/medium length hair. She’s 5’6 and her body is a typical Indian housewife (chubby, not too fat), she has a pretty big ass as well. It’s not huge, but noticeable in jeans/tight skirts, etc. She has a light, light brownish skin tone. Anyway, my cousin is 19 with a dark brown skin tone, short black hair and pretty muscular. He’s about 5’8. My family consists of, My dad, mom, brother and I.So onto the story. My mom and cousin have gotten closer over the years. Closer as in, they usually talk once in a while every time he comes over for dinner, etc. One weekend, my cousin came to sleepover. He has done it before and this isn’t the first time he slept over. Later on in the night, we went to a movie. We came back and my brother, cousin and I all went to my room and played video games. After playing for a while, my cousin said he was tired and wanted to go to sleep. This was unusual because every time he slept over, we usually play games until 3 or 4 in the morning. However, it was 11 and he said he wanted to go to sleep. After that, we still played for a good 30 minutes, then he insisted that we go to bed. He seemed like he really wanted to go to sleep, and so I said “fine” and got ready to go to bed.My cousin sleeps in the guest bedroom, my brother has his own room and I sleep in mine. I couldn’t sleep. I was ready to play games with my cousin till 3 or 4 in the morning, but instead I was stuck going to bed at 11:30.Time passed and it was about to hit 1 o clock. I had to go to the washroom. Did my business and came out. As I walked past the stairway, I heard a slapping noise downstairs. Something like skin hitting against each other, like if you hit your leg repeatedly. I looked around and all the room doors were closed but my brothers. I slowly walked downstairs, all the lights were off. The slapping noise slightly got louder. Suddenly I stepped my house the stairway made a small creak sound. The slapping stopped almost instantly. I could kind of hear someone breathing out, but then it was total silence. I slowly walked back upstairs. I looked inside my brother’s room – he was sound asleep. I slowly opened the guest bedroom – my cousin wasn’t there. “Hmm, maybe it was him downstairs. I wonder what’s up” I thought. I went back downstairs. I did it quietly, hoping if it was my cousin, he wouldn’t hear me so I’d be able to scare him. I could hear some whispering, but I couldn’t make out who it was. I made it downstairs and into my kitchen. From my kitchen, I could see the whole living room. In my living room, I have 3 couches. One on each side of the wall. I slowly walked forward and saw my mom’s night dress on one of the couches.I had no idea what was going on. Curious, I walked forward a little more. Across from the couch with my mom’s night dress was her, sitting on the couch fully nude. I got scared and moved back a bit. Interested, I ducked down and slowly moved to the edge of the kitchen to get a better view. The lights were all turned off except for a small night light. From that I could see it was indeed my mom. To my surprise though, she wasn’t only sitting on the couch, but also my cousin. I was shocked, I couldn’t believe it. My cousin had his shorts down to his knees with no shirt on. My mom was fully nude. I looked around and saw my mom’s bra and panties on the ground beside my cousin’s shirt. I looked back and them and saw my mom kissing his cheek and lips like she was possessed while my cousin played with her boobs. Then my mom started to get humped. The same noise I heard early came back. My mom’s ass hitting my cousin’s legs were where it was coming from. She went up and down sitting on my cousin as his penis went into her pussy. She was closing her eyes whispering “Jesus” and “Oh God” in Tamil. With a couple of soft moans. My cousin just kissed her back and held on to her waste. After a couple of seconds past, my mom stopped and got off his dick and stood back first in front of my cousin. My cousin was stroking his dick looking at my mom’s ass. He then grabbed it and stuck his fingers in her ass hole. She moaned a little, then he stuck his fingers into her hairy pussy and rubbed. My mom then said “enough for today” and moved his hand away. They kissed each other one last time and that was the end to that. I don’t know if they’re still doing it. I kept my mouth shut and didn’t treat anyone different.I should have been mad, but I enjoyed it. Hope you guys did too.
