She screamed out with passionate agony, YEHHHHHHHHHHHSSSS! Her scream was so loud I could have sworn someone would come looking for us. I was now blas...ing the inside of her ass, releasing more cum than I thought possible. It was already dripping out my mothers ass before I was finished. Halfway through finishing from behind her, she pushed against the ground forcing her ass even harder onto me. Because I was already at the top of my threshold, this shot a final wave of pleasure in me that. I then moved my mouth up and down, rubbing my lips along the shaft, with my tongue tasting the length, while salivating like a bitch. He then started guiding my head with his hand and kept my head bobbing and working his stiff, pulsating cock. I gasped for air couple of times in between, and then went back down for that tasty meat, like a hungry whore.He started groaning, lost in the pleasure my warm, eager mouth gave to his meaty, hard cock. I could smell his pubes and the sweat there, and it. During that last period, which I had started to peek my nice sister (as i have recounted in my previous stories :-P) I had practically completed :-P of to see all her parts :-P (ass and buttocks naked in this last episode :-P, tits with nipples, whole pussy, and then a nice moment when my sister was sitting on a chair with her view front and total with her bare and white legs wide open or well wide apart (as you prefer :-P) and bent and with her feet bent on tiptoes and calves at ball :-P, was. I knew I would have a hard time waiting until nearly 5:00 to go to her house but I knew her husband had a job that kept him away for long shifts and we'd have several hours alone hopefully before anyone was likely to interrupt us.At 4:45 I pulled up behind Holly's house and parked where she'd wanted me to. I could see her car in the garage and I went through the gate of the backyard fence and tried the backdoor to see if she'd left it unlocked for me. It was open so I slipped inside and tried.
