Yep 8 inches, maybe a touch more, straight and narrow practically filling the distance between the siblings. Cindy looked down and all I could see was...her two hands coming to her face in an "oh my" expression."Holy shit, it's, it's really big" And with that Cindy reached out and grasped her brother's hard cock. With both hands. And there was cock to spare. I sat quietly watching to see where this would go. If Cindy went "there" how did I feel about it? So far, ok, I guess."Sis, what are you. How a real man . . .thucks his . . . ifes thloat . . .Mathter"She took a deep breath and then he pushed deep into her throat "GGGGGUUUCCKKKKK!!", until her nose was buried in his pubic hair. Her neck bulged out obscenely where his thick shaft was clearly buried.Jaymes pulled about four inches out of my wife's throat before thrusting back in. He started moving her head faster and faster, using her throat to masturbate. I was mesmerized watching her neck rhythmically bulge out as he fucked her. 30 pm and because I wanted to take her to the Marine Walk I asked her, "Shall we leave now mom?"She replied me in a playful manner, "You are the man. It's your decision."Then I paid the bill and we left the hotel. Once again we were holding our hands and we slowly walked to our car. She stopped close to our car and turned to me, "This is the best night I ever had, Jason. Thank you."I kissed her cheek, "Don't thank me yet mom. The night is still young."She looked so happy that night and I had. She was wearing trousers that were not exceptionally tight but tight enough to suggest the contours of her large buttocks. She returned shortly with a riding crop in her hand and as Adam opened the car door for her she playfully ran the crop against his crotch."Lilac Cottage for some fun now and until I tell you otherwise you can call me Emily or anything else that you want to call me," she said as she felt some dampness between her legs.Adam's reply of, "Okay bitch," caused a smile to light up.
