As his tongue reached the head of my dick I jumped from the sensitivity. Bringing his tongue up and around the head, he circled it before licking his ...ay to the base of my dick. My knees were turning to jelly as he ran his tongue around the base down to my balls. Reaching up he lift my ball sack and licked my scrotum before moving down the back of my sack. I thought I was going to cum right then. Mark stood up and took my hands. He walked me to the bed and laid me at the foot with my legs. Soon he could feel a tingle growing deep inside,“Becky, you’re going to make me blow.”Her only response was a contented throaty purr and she firmly gripped his hips with both hands. Her lips clamped down on him and after just a few more bobs of her head he reached the point of no return. He groaned, gritted his teeth and shot come down her throat. Then as she took him out of her mouth, he came onto her chin and splashed come onto her shoulder. She continued to milk him all the while until,. I'd just discovered masturbation. When I first did it, I didn't reallyrealise what it was that I was doing, I just knew if felt good. I hadn't even started to physically 'cum' at that time, I just knew an orgasm as 'the d**gged stage' which happened after rubbing my cock for long enough. It was all very new to me. Wind forward a few years, and Jim and I would sleep over at each other'shouses quite a lot at the weekends and during the school holidays, particularly in the summer, and this one hot. When I suggested she take some semi erotic pics, she agreed although Mandy wasn’t sure.I told Mandy just some photo’s of us undressing each other and simulating sexual positions. Anyway she eventually agreed. We started with us kissing and slowly undressing each other as Kathy took the photo’s and to be honest I was getting quite turned on. Kathy said she had to go and get some more film, these were the days before digital cameras.When she was out of the room I told Mandy I was getting turned.
