Susie didn't share their taste in nightcaps, and had just downed her third vodka and orange. "I've got a treat for you little brother" She said, as sh... stroked the top of my leg. I asked her what she had planned, but she told me that I'd just have to be patient, and I'd soon find out. Mum and dad returned with their drinks, and stayed with us until the news ended, before saying goodnight, and going up to bed. About 15 minutes had elapsed, when my sister told me to go to the foot of the stairs,. ? When balls are milked, the pain shoots up to the kidneys? I shouted when I could take the pain no more?.she gave me time to rest, and again started milking my balls, but she never let go of the pressure.? She did her milking extremely hard which made me feel like vomiting, as the pain was unbearable. I lost my erection and started begging her, promised her that I will drink her urine next time as she had ordered, but just leave me.? She continued with her milking for a few more minutes and. Her master would be very pleased by her discovery. She kneeled again on the soft dirt floor of the cave and proceeded to jerk his cock. It throbbed in her hands as she tightened her grip. There was something in that cum. It seemed like a strange aphrodisiac, and it made her horny. She had to some how hide that fact that she still had her hymen. She had never given her virginity, much less a blow job, but she had this strange need to. She couldn't resist the feeling anymore, and she licked it. I turn around to face her and kiss her passionately pushing her against the wall. We don’t say a word, we’re caught in the passion of the moment. My hands roam as we kiss, moving up under her top to feel her tits. I’ve wanted to do that for so long. I pull back and we fumble to pull her top off and undo her bra as we continue to kiss. Our tongues are a whirl wind. She reaches down and under my skirt and pulls my now very damp panties down to my ankles. I feel her small soft hand touch me for.
