Masturbated at bedtime

During the summer holidays I got sent off to a farm for a month, while my parents sorted out their troubled marriage. I stayed there with another k** Graham who had been there for a couple of weeks already. We shared a bedroom in the farmhouse which was run my an oldish couple in there late fifties. Everything seemed kind of norman until Graham and I were sent up to bed, We both got changed into our pjamas and got into bed, then I looked across at Graham, he had pulled the covers down and had also pulled his pjama bottom's down exposing his erect penis, which he was stroked, I was no embarressed and though he was coming on to me or something. Then the door opened and Auntie Rosemary walked in (I don't know why we had to call her Auntie as she wasn't). She walked up to Graham's bed and took hold of his cock and started to wank him, placing a towell across his chest. I watched on in fascination as she pulled his foreskin up and down, until Graham started to buck and grunt, suddenly a fountain of white sperm shot out onto the towel as Auntie Rosemary squeezed out every last drop from his wilting cock. Auntie Rosemary wiped away all the sperm from Graham's cock, then smiled at me, 'come on then it's your turn, get it out' she said. She walked over and pulled the covers back, I looked down and could see my own erection showing from my pjama bottom. Auntie Rosemary tugged them down, my cock slapped against my belly as I showed my erect cock to a woman for the first time. An shot of electricity went through my body as her hand took hold of my swollen dick, she slowly pulled my foreskin up and down, leaving it drawn right back, it felt to sensitive to her touch. A tear of pre-cum dribbled over her fingers as she started to masturbate me, my balls all tight. I look over to see Graham watching intently, I look at Auntie Rosemary's ample cleavage as he boobes wobbled as she wanked my harded, suddenly my head started to spin and my body shuddered and I released what seemed like a gallon of hot spunk over the towel, although I could feel the warm of it through it. Auntie Rosemary laughed and called us her little spunky monkeys. She went on to wank us off every bedtime for the rest of our stay, apparently to stop us masturbating ourselves, trouble was I enjoyed it so much I used to get a couple in myself whenever I could.
