Damn Suspicious MIL

Confession goes back a long time to around the early 80s. Me and my new wife went for a road trip to DC for a long weekend. Her parents and two younger sisters also went cause they had some cousins or something in northern VA and we were supposed to join them Saturday evening for a BBQ at the aunt and uncles place.
So my one sister in law is like ten years younger than my wife but the other sister in law is just two years younger than my wife. That one who I will call Teresa had flashed me her bare pu$$y a couple of times when we were all watching TV together. She was in a cotton nighty and slowly, erotically crossed her legs and never took her eyes off me while she was doing it. She spread them and showed me some pink and even a bit of red inside lips! She was also frequently needing something fixed or adjusted, looking to rub up against me and asking if I liked her perfume and stuff like that.

So this time we went on this trip and when we got home that Sunday night my wife got a call from her mom telling us that they had broke down outside of Alexandria VA and they had to leave their car at a mechanics shop and were taking the greyhound bus home. I had to go into the City to meet them at the bus station.
The next day I rented a heavy duty van and a tow bar so I could go to VA and bring back the in law's car and work on it myself. So I was hoping to get my SIL who was flirty to take the ride down with me and maybe she would sit in the car while I towed it back. Seemed like on the trip down maybe we could fool around a little at a rest stop or something. Or once we got to the place and hooked up their old car with my rental van I could maybe at least get a blowjob.

So I go to my in in law's house and see the hungry one is ready to take the ride with me and I'm hoping something extra happens too. Suddenly the pain in the ass, always talking mother in law says she's ready too. My face must've said I was up to no good because the MIL made it 100 percent clear that she was coming along and making sure there was no funny business on the road trip. Damn woman yacked all the way there and naturally all the way back, barely pausing for a breath of air.

I was really pissed cause I figured I'd have got some SIL pussy or at least some head and instead I got an earful of the old lady bullshitting across a couple of states.
There came another time a few years later when I did get to feed my dick to the horny SIL but that's another story for another time.
