Friday morning, I showed up at her house at 8 a.m., as planned. We loaded her gear into my car and headed out of town. It was a very pleasant drive, b...t we both seemed a little forced with our jokes at first. We were just a little too nervous to be natural. It was incredibly exciting, though, to be going away for the weekend with her.While driving down the road, she decided to have some water to ease her thirst. Sometimes I get urges to be mischievous and one of those urges hit me while she was. Baby, you...you need to move back a little, your cock is touching my arse and we shouldn't be like this. I can finish washing myself now, so it's alright." Mark stopped moving his hands and just wrapped his arms around his mother loosely, leaning his head on her shoulder and speaking softly in her ear. "Sorry mum, my...well my cock is really hard again. Can you feel it?" His question sent a shiver down his mother's spine, it was so innocent and yet so intimate that she didn't try to move away. "Yes, I think so. Just because she's had a rough start doesn't make her into a criminal."Well I decided that the devil I did know was better than the devil I didn't. At least I wouldn't have to worry about her trying to bed me. She was 20 years younger and not even an adult legally. It also meant that Ethel and I could get back into our old routine. I missed her sensuous body, and our sex, and I hoped she did too.So I said, "OK, she has already had a three week trial, so I can't really give her. I was so scared to pull my shirt off and look at them, touchthem, everything; but I thought, "They are my boobs. Why should I be soscared?" I closed my eyes, pulled the baggy tee shirt over my head, andthrew it to the floor. I opened my eyes again.I was wearing a white bra. I reached behind and tried to get the claspundone; after two tries it opened. I pulled my bra off and threw it tothe floor. I looked in the mirror at my breasts: They were a 32Caccording to the bra's tag. My nipples.
