Just watch and see what happens

So I decided to wait and see what would happen. The house was dark and actually deep in the woods. There was no chance of being caught by any neighors. It was actually quite boring at first. They just sat and drank wine for a while...

You could tell Joe wanted to make a move. He kept checking himself and looking over at Jessica from time to time. Jess just looked like she was waiting for something to happen.

I took this opportunity to walk around to the back and get a better view from the back screen door. The lights in the living room created the perfect reflection as to camouflage any peeping I might be doing.

I was realy jealous and angry, but turned on as well. There was something about Jess fulfilling ome sexual need that made her look so hot on the couch. Like she was willing to go to any length to satisfy ome primordial urge to get as much cock as she could.

As I looked in I started to think maybe this was all in my head. But I couldn't understand why she lied to me about it still....

Just then it happened. Joe put his glass down. He began to move around and fumble with his pants, but I couldnt see anything because their backs were to me, and the couch got in the way...

Jess turned to look, then looked down, and then gasped. Joe grabbed her by the back of her head during the shock and gently nudged it forward into his crotch. She went down with no fight, and I began hear his moans through the window.

He must have had a huge cock too because I could hear the slurping sounds Jess was making as she was bobbing her lips over it. Plus she came for air for a few seconds, and her face was completely covered in slobber. She open mouthed Joe on the lips for a fe seconds, and i could see her right shoulder still moving up and down as she probably continued to jerk his dick.

I didn't know what to do. I had let this go to far, and I also didn't want to stop it.

Jess stopped kissing him and went back down to slurp on his dick again. His head started to lean back as she was giving him the pleasure he wanted.

I started to think about the engagement ring and how it must be rubbing all over his dick...

I tried to get a better view, but it was just impossible.

Luckily, Jess lifted her head again and then stood up. She looked like she was in ecstasy. She got in front of him gave him another kiss and then reached down to tug on his shaft. She motioned him to follow her, and Joe stood up. She led him past the couch with her hands still jerking his dick behind her. He followed suit by slapping her on the ass.

She giggled as they reached the stairs near the couch and started to walk upstairs.

At this point I had a huge hard on and did not know why...I checked the back screen door, and saw that it was unlocked. I know I could open it with no noise, and sneak in to see what happens, but the question was did I want to continue down this path...
