.....I dimmed the lights and only the video lighted the room.The video was two guys with a girl. Knowing how a s*******n year old would get turned on ...ith the way the night wad progressed and the liquor was having an effect on his sexual state of mind. I put my hand on her thigh and noticed he all ready had done the same. She put a leg over each of ours. and I pulled her top off. Turns out she didn't have any panties on. After all the attention from both of us she stood up, took his hand and. "In the kitchen getting food ready for tomorrow," she said. "You should go in and see her, she'll be so happy you're here."I walked through the living and dining rooms and peered into the kitchen, just as my mother had bent over to pull something out of the refrigerator. She was wearing sweat pants and a T-shirt, her customary loungewear over the past few years. Her sweat pants fit like a glove on her thick thighs and round, bubbly butt. I was tempted to rip them down her body right then and. Her nipples got huge and full and before long I shot my cum in her and she took every drop. "It's time to go" she said and I said "go hell I just came". We both laughed and we went on our way.After the pre-op stuff I was laying on a gurney and Betty was at my side. The nurse was checking my vitals and she commented if I was feeling OK and had I taken any d**gs in the last 24 hours. I said no and she had a look of disbelief. Betty also commented and asked the nurse if there was a problem.. After about 3 minutes of sucking me off she laid down in the tub and started to masterbate through her panties. She came not only once but twice in a few minutes time. She then pulled down her panties and told me to fuck her. I complied, but hesitated for a second. I eventually just sat on my knees in my shower and without even a seductive look or a ok go ahead from my sister I rammed my dick into her pussy, and at first she was different i could tell from all the other girls i had slept with,.
