Dawn, as expected, meekly went along.Then Heather shocked me. "Sounds good to me," she said."Huh?" I said."Sure, I'll bite," she said, shrugging. "Mig...t be fun."I never expected her to go along with it. But she did. Shit! The next thing I knew, Tom was standing up out of the chair, grinning, and shaking my hand. "It's settled, then. We'll see you in two weeks. I'll bring the snacks. You just bring your gorgeous wife." And then he and Dawn left.Heather sat there, grinning at me. I wiped the grin. The only good news was that it was starting to get darker and in another 15 minutes it would be pitch black. I couldn’t see the driver’s window without leaning down into the passenger side but as I did, I saw him staring right back at me. I also noticed that his right arm was pumping up and down while he was grinning ear to ear. My fears disappeared and the exhibitionist started to come back. As I took a moment to check out any other possible voyeurs I realized that as long as I didn’t raise. I couldn’t stop myself from noticing the swelling of her breasts, her slim legs and her full lips. The shadows lengthened and the sun started to set, we’d lost all track of time. The conversation felt like we were falling in love. I asked if she was hungry or thirsty, but she said no. She yawned widely, then apologized. “Oh, hell, baby,” I said. “I wasn’t even thinking, you’ve had a long day. I made up the spare room, it has its own bathroom. As for the rest … mi casa es su casa, you can have. Fuck me…! I then proceeded and I pushed hard, real hard and finally her tight wet pussy lips and pussy parted and I slid my hard cock all the way to my balls!Marlene’s pussy was soooo tight, felt sooo good… I nearly shot my wad right then!!!! I had to really work hard not to cum and I actually pulled out…trying not too cum! Marlene reacted moaning harder and I think she thought I was teasing her! I was trying not to cum! Don’t know how I did it, but I was able to calm down to where I wouldn’t.
