We’d taken time out for dinner – Chinese food, delivery – but by then we were aroused to the point that even during dinner the touching and play...ul sexual innuendo continued.I’d always considered myself to be very adventurous sexually, but Lynn was a revelation! There seemed to be nothing she wouldn’t try, even if only to satisfy her curiosity, and we’d had a lot of slippery, sexy fun sampling new things. I’d found that she could get a little kinky, a bit extreme sometimes, but it was always. It was getting dark, so Jon suggested that he had better drive Derek back down the mountain to home. “No need to pack up though, I’ll just come back in the morning” he said. That left me and Jon and Derek’s co worker and friend, Matt. I didn’t really know Matt that well, but it was fine. He seemed like a good guy and there was no reason for all of us to leave. We set about finishing the camp site and soon had a nice fire going. We sat near the warmth of the flames, having some beers and. It was not with anyone else. If you had not done that I would have to bear all that pain.Mum: But still.Me: Would you have preferred I be in pain or had gone to some girl who would have done that?Mum: No, especially not a girl.Me: Then there’s nothing for you to feel guilty.Mum: But I should not have enjoyed that whilst I was helping youMe: You are human, you also have desires which dad is not fulfilling so it’s natural. If dad is not able to fulfill his duty, as his son that falls upon me to. Then it happened! My legs twitched, my abs tightened! I let out a loud moan as I felt the fluids erupt through shaft and in to my sister’s waiting mouth. Expertly my sister milked my slowly deflating member.When my sister was convinced she had gotten all of my liquids she let me fall from her lips. Seductively she looked up at me. ‘Well, that takes care of that fantasy.’ she murmured.It took me a minute to get the feeling back in my body. Then I pulled her up and our lips.
