Oh, never mind. She's my Mom, for gosh sakes, I told myself. "There's only one little problem," I added. "I have to go like this, because the assignme...t doesn't end until Sunday, night, according to the rules of the program." Oh." Mom mulled this over. "How does Beth feel about it?" She's cool with it, once we talked it over," I explained. "Dinner's ready!" I called Sis."Coming," she called unnecessarily, her feet thumping on the stairs. "Oh boy, naked supper!" She giggled."What about her. "Aaaaahhhhhh"!!! My sweet wife screamed. I knew she had never had such a big cock like that inside her. The bastard had a giant piece of meat really. He pinched her nipples as he rammed her.I enjoyed this so much; my own cock was hard as a rock.Then this lucky bastard pulled his dick out of my wife's pussy, telling her to bend over on her hands and knees. He spat on his hand and rubbed her tight asshole. I was so fucking excited; since he was going to fuck her in the ass, as I just watched in. In reality, I was ready for a change and a chance to see my sister again.During the long ride back to my home I tried to determine how much the new guardian would know of my situation. If he had known all of it, I would probably still be at the academy. My best posture was that I had simply gone off to live with friends of the family. I would have to see what he knew about me for sure.I wondered about my sister and her attitude towards me after a three-year absence. Sometimes, you just had to. I put my head on her lap and removed the barrier between the two seats and she put a blanket on me n her and started playing with my dick and I sucked her nipples one by one . I had my best hard on that day and was going just crazy all the while . She was stroking my dick under the blanket and I could hear her loud breaths .Then I got up asked her to unbutton her pants and I started paying with her clean shaved pussy and fingered her for almost 10-12 mins and massaged her sexy clit pinched it.
