My Wife's Friend and our Neighbor

Ok so my Wife is friends with the neighbor next to Us for ten or more years. We've always had a relaxed way of talking to each other. She's been flirty towards me and I have been too. In the past we've been a little hands on, like a grab ass here or a long hug. But yesterday I stopped by to drop off holiday cookies and she asked me in for coffee just to catch up since I don't hang with them when my Wife does. After to talking she got up to put the milk away and her pants were really low. Lime just half way down here hip. When she turned around her shirt didn't cover the top of her pants. I could see the cut on both sides below the waist. Low enough to see she probably shaves completely. So I said nice pants, and I said I'm going g to guess you4 totally shaved. She says maybe, want to see. I told her I better not. She pulled her pants down a little more. All I could think was just keep pulling them down please. She didn't. We couldn't keep my mind off of seeing her with her pants around her knees. On the way out she gives me a hug and I thought she pushed herself into my groin. I said I should pants you to serve you right for walking around like that. She says go ahead. I can't my Wife is her friend and our Neighbor. Before I know it she kisses me happy holidays but with the hottest tongue I've gotten in some time. Being married 20 years leaves you missing out on lots of things. I instantly got hard which she pushed herself into. Fuck I could explode on here. Finally I get to 5he door and on the way out she calls me chicken. I immediately turn and with both hands on her hips yank her pants down. Oops she wasn't wareing anything. I quickly apologised but she made no move to pull them up. In fact she moved her leg and they fell to the floor. I kept looking. She'd be on her knees in 10 seconds if I stepped back in but I coucouldn't just leave. I did step back in, stepped right in front of her bent down my face 3 inches from the best pussy that I wanted to spend two hours on and pulled her pants up. I said hold on to that. I'll be back for it. What can I do? I couldn't just leave and I didn't want to turn her down. God she's hot. Hot enough to write this out today of all days. Now it's all I can think of. I do have two things going for me. My Wife isn't into sex anymore do to a medical problem and everyone thinks her husband is either gay and at least a douche towards her. I will take that but not a 5-10 minute quickly. I hope she's thinking about it and that makes it even hotter for her. Seeing her Pussy and then close up is all I see in my mind. To be continued. In January my Wife and k**s are going away for a three day weekend and I have to work. But if I can make this happen I'll have video for months. She will definitely not her herself after that weekend. I should of put my hand in her pants after I pulled them up so that now I'd have her smell on my fingers!!
