At least that was going according to my plan. I told her that, had we gone to a nicer restaurant, that she would have been made to go to the ladies ro...m and return with her panties in hand and then would have handed them to me at the table. So much for that plan. I handed her a small package and had her open it. It was a small pocket vibrator. She was enthused with her gift. I pulled out of the parking space and instructed her to raise her skirt to her waist, spread her legs and put her new toy. Her tits hanging in my face and I was gripping and slapping her ass. She was making sexy faces, biting her bottom lip with her eyes shut. She had to put her hair in a poly tail because she had kept pushing it back. She rode me for about 10 minutes or so.

Her waist is real skinny, and her ass really nice, so when she arched her back, it looked soooo nice. She was moving back. I wanted to stay naked with her, and my continued erection showed how willing I was to stay that way, but Helen seemed oblivious to her nudity.When the film cannisters had finished being developed, I followed Helen into the darkroom as she prepared the contact sheets. I stood beside her as she cut the negatives and laid them out on the photographic paper. Our skin brushed several times. For me, it was a source of greate erotic electricity. I wondered if she could hear my breath catch as we. We were now comfortable with each other on most of our topic. We used to talk about almost everything now.

I resisted initially but after some time I stopped resisting. I was finally indulging into his conversation. I was enjoying each bit of that conversation.This was the first time we were sexting. I.
