The summer after I graduated from high school was looking to be a pretty boring time for me. I was working part time in construction while living at home with my mom Sharon and my younger sister Jenny. We lived in a three bedroom trailer in a trailer park near the edge of town. My older sister Bobby-Joe lived a couple trailers down with her boyfriend Kevin.
My name is Sid and I was nineteen when I graduated because I failed second grade but it didn't bother me because I kind of liked being older than the other kids in school. Having sisters about a year and a half on either side didn't hurt either. I was always trying to get with their friends and from time to time I was even successful. Bobby-Joe and Jenny were both kind of small and pretty so they had no trouble with the guys and being their mothers daughters they took full advantage.
Now mom wasn't a major slut or anything but she was pretty good lookin' and with my dad out of the picture pretty early she usually had a boyfriend, and every now and then she would even have one-nighter, or more accurately a weekender. I was dating one of Bobby-Joe's best friends Samantha, and for the most part life was uneventful but good. That's when mom started dating Jack.
It had only been about three days but I knew she had it for him pretty bad. She was dressing sexier and was always out with him. I even heard her fucking him through the walls. Now, I have heard her have sex before, that's one bad thing about living in a trailer, but this time it was different. It didn't even seem like she was trying to be quiet. She was so damn into it and it seemed like she would do anything Jack told her to do. I have to admit it was erotic as hell and I jerked off listening to them more than once. I wasn't remotely prepared for what happened next though.
It was Tuesday afternoon and work got rained out so I went home early and when I opened the front door mom was on her knees in front of Jack blowing him. She started to get up and say something but Jack stopped her.
"You don't have to stop, I'm sure Jack knows what we do and I'm sure he's done the same with his girl," he said.
"But Jack," she replied.
"Doesn't bother you does it Sid?" Jack asked, gently guiding moms head back down over his shaft. "Yeah there you go baby."
"Whatever gets you goin' man," I replied. "I don't care, It's not like you guys are quiet about it anyway."
I went into the kitchen to make a sandwich and get a coke but I could still clearly see what was going on in the living room. Mom continued sucking Jacks cock and Jack just kept talking.
"Does your girl suck on you like this Sid?" Jack asked, not waiting for an answer. "I'll bet she does it topless though. Take your top off for me so I can see them sexy titties while you suck me Sharon," he continued.
"I can't believe we're doing this where my son can see," mom said as she rose up and removed her top, fully exposing her breasts, that are actually very nice. They were slightly dipping, probably a C-cup,with normal sized nipples that, at that moment were clearly very hard. I have to admit that those C-cups looked amazing on her small frame. Needless to say I was hard as a rock and a little shocked. I had never seen mom so submissive or so sexual. She lifted her hands behind her neck and stuck her tits out a little to show them to him. "Is this what you wanted baby, to have my little titties out were you can see 'em?"
"Yeah baby that's what I like, show us those sexy candies while you suck me," jack said and playfully smacked her left tit, causing it to bounce a little and her nipple to harden even more before she lowered herself back down and got back to work on his ever hard cock.
"Does she make you cum when she gives you head?" he asked, this time expecting an answer.
"Sometimes," I answered still surprised that he was having a conversation with me while my mom was blowing him, and mom was really working him with her mouth. She had a nice rhythm with the occasional slurp sound that was sexy as hell and I could tell Jack was loving it because, despite his best effort to casually chat with me, he would moan every now and then and tense up and tell mom how good her mouth felt and looked.
"Man that must be nice, I've only had a couple of women that could do that for me and your mom Sharon here isn't one of them,she tries really hard and comes oh so close, but never gets me there before I have to flip her over and fuck the hell out of her to cum, so either you're an easy nut or your girl is good, either way it's good for you right," he continued. "So who do you think gives better head Sid, your girl or mine?"
I was almost finished making my snack at this point, "I don't know man, she's my mother for Christ's sake, she seems to doin' a pretty good job for ya."
"Yes she is," he answered, turning his attention back to her. "Are you ready to put me inside you Sharon?" he asked.
"Oh god yes," she moaned rubbing his cock all over her face as she did.
