You see, I know about you using my keys to open the front door in what I'm quite sure was an attempt to leave without saying goodbye. I even know that...you tried just about all of them in the door to the garage, so I'm not even going to ask for an explanation."His whole body went cold."Now, you were trying to leave, weren't you?"His mind raced for some other explanation, but in his condition he could hardly think straight, yet alone be creative. He didn't have to think long as she chimed. “There’s a lay by up ahead soon pull in there”, she replied few hundred yards later I pulled in and as soon as we stopped her head went down onto my lap and her mouth took my raging cock into it I moved my seat back and watched her grey hair bobbing up and down on my cock sucking me and cupping my balls wanking my shaft. “I’m going to cum I said, she lifted her head looked at me and said cum then I’ve been thinking of this ever since we fucked in Rome” and dropped her head down again and. My lips parted and took her tongue in to my mouth. She began to suck my tongue. By now she had fished my cock out and was stroking it. It was so wild and erotic, frenching my mum while she wanked my hard young dick. As we kissed, I reached inside her bathrobe and cupped her firm 38C tits and began to fondle them. Her nipples grew hard in my fingers. She moaned softly around my tongue and squeezed my cock in response. "It's been so long since I have had a hard cock to love that I just have to. She does have exceedingly nice tits."She's having a shower," I told mum when I returned downstairs.My mind wasn't on my eggs though but on my sister's body and what I was going to do with it.As the day went on she became more and more with it and I noticed she looked at me strangely from time to time tying to get her head around her fogged memories no doubt.When I started all this I reasoned that I only had the weekend to do anything. 1, because mum and dad were generally out most of the time,.
