As we do several times a year, my family made a trip down to Tennessee to visit my sister-in-law Erica for a long weekend. She moved down there several years after she got married, into a nice house with lots of land for her animals. Sadly, she lived like a single mom for about half of the year as her husband spent about 6 months of the year away for work, and our visit landed during one of those times.
Making the trip this time were me, my wife Sara, her cousin Laura (who you know plenty about if you've read my previous stories), and Laura's older sister Kelsey. Erica had a nice, big house so there was plenty of room for everyone. My family had a room to ourselves, and Laura and Kelsey shared a room. Not much of a chance to sneak off with Laura, I lamented.
When we got in that evening, we were all very tired from the drive so after the usually pleasantries I excused myself to go to bed. I brushed my teeth and got into some more comfortable clothes in the bathroom before proceeding to our room. On the way there I passed Laura and Kelsey's room, and through the cracked door I noticed Laura had come up and was changing as well. She turned to see me peeking, and pulled her pajama top up to expose her tiny tits and brought her finger up to her mouth like she was shushing me. I'm assuming to tell me to keep quiet. She proceeded to suck on that same finger, bringing my cock right to attention. All of this happened in a matter of seconds, and I realized my wife was coming up the stairs. I continued on my way as Laura heard her as well and went back to changing.
I laid down, and under any normal circumstances I would have rubbed on out after that whole exchange. Unfortunately, with my wife in bed with me and our son in the other bed in the room, that wasn't an option. So, off I drifted with thoughts of that dirty little slut running through my brain.
My wife woke me up around 7 the next morning and asked if I wanted to go down to the barn with her and the kids to help feed the animals. I passed, saying I was still pretty tired and could use a bit more sleep. Annoyed, she left and closed the door. I was, in fact, pretty tired as in no time I had dozed back off.
I was having a GREAT dream, surprisingly about my wife giving me quite the blowjob, when I woke up and realized it wasn't just a dream. Someone was under the comforter sucking my cock. I could tell by the outline it wasn't my wife. She's built pretty thick and has a nice, big ass. Whoever was under the comforter didn't have an ass anywhere near as big as hers. Process of elimination, it had to be Laura. She'd clearly been working on her deepthroat skills; she couldn't quite take me all the way but she could take about 3/4 of my shaft now.
"Mmmmmm, Laura," I said, "I didn't think we'd get a chance this weekend. You sure we have time before they get back?"
"Wait, WHAT?!?" came a voice from under the comforter as the blowjob stopped.
My blood ran cold. That sure as HELL was not Laura's voice. Had I misjudged things and it actually was my wife? No, I thought, that wasn't her voice either...
The comforter lifted up and I saw Erica's face in shock. She said, "You've been fucking LAURA?!?"
