My heart started to pound with excitement at what I could see and hear. He had his hand between her legs fingering her pussy and kissing her passiona...ely. The rougher he fingered her, the louder she moaned. I felt guilty spying on them but at the same time was getting really turned on. She was writhing her hips as he pulled her pussy lips apart and slid his fingers inside.He then pulled down his tight little black boxer briefs to reveal a very hard and throbbing cock, so erect it bounced. I also like that Lynn is taking charge. I place the chair facing them and sit down. Jim and Lynn turn to face me. Jim puts his arm around Lynn's shoulder and Lynn leans into him just like they are already a couple. "Hanging out with Lynn has been really good for me. My wife died a few months ago and I have missed female companionship." “Jim shared some good memories of John, too.” As Lynn says this, she gives Jim a warm smile. "I am sorry to hear about your loss, Jim. I can tell that Lynn is. This piqued my attention, half witless through the drink and driven on through ecstatic desire, I took my place at the side of the pool. Instantly, I felt hands on my ass, from somewhere. Hands were groping my increasingly erect cock, hands up on my chest and thighs, then warm hot piss at the side of my leg. I pulled in front of the bodies, and brazenly stood in the pool at the head of the couple and presented my now rock hard cock straining at the cock ring. The guy on top took it in his mouth. My sister continued to undress so she could be as naked as the remainder of the present company as quickly as possible. I gave up all hope of hiding my incestuous relationship with my younger sister from the powerful woman and hoped that Princess would be able to mollify the older woman with her usual sparkling personality and willing tongue.When the first light of dawn broke through the partially open blinds, I was sandwiched between their beautiful flanks on both sides. I was still awake.
