I was kissing her on the neck and the face,also caressing and pressing her boobs. Her breath was getting heavier.I was pressing her boobs over her top... I was also sucking them a little. She removed her top. Now she was in bra . Her boobs were beautiful. Firm and properly shaped. I started pressing them over the bra . I was also kissing her on the lips and neck. I sucked her left boob and presses the right one. I did it for a while. She was moaning.Then i undid her bra.Oh my god, it was a sight. I had Mark on the phone working with Melanie back at the office. She had a CAD program on her computer. They were designing a security office from scratch; two desks were not going to do the job. I had repeatedly made the office changes at the sites we took over and Mark was always involved in those discussions. This would tell me how much he had been paying attention to details.I called Bob of Bob's construction and began asking questions, "I wanted ball park figures for building a guard. Then he would proceed to undress mother. When she was fully nude, he would kiss her all over and suck her nipples. Her breasts were still firm and nipples dark brown and long. After sometime, her nipples would grow erect. He would then start kissing lower down till he reached her cunt. He would dig his face into her bush – mother had a bushy cunt – he would lick her and rub his tongue and nose in her cunt for sometime. By then she would be aroused and she would pull him up, kiss him and start. I told her not to worry and its natural to have those feelings at her age then I educated her about sexual tension which comes and has to be relieved and all, I asked her whether she knows about masturbation she said no, I told her you masturbate and your sexual excitement will be relieved and you ll be able to concentrate on your studies. I didn’t have any intensions of sex with her and she was 8 years younger to me. I was happy to have her as my best friend. She asked me will I help her to.
