We talked for a while about Mark & our position with him,Jamie told me,he was trapped the same way as myself,"I,ve accepted it Roy,he,s not so bad,loo...ks after me,same as he will look after you,but to-nite we are both his friends Fuck Toys,you know you,re Gay so enjoy it,I do",he gives me a hug & says,"You;ll be OK".I smile at him,"Do my best",I say.We get talking about knowing each other at school & nobody knowing Jamie is Gay.After a few drinks in the kitchen we join the party,myself feeling. Like a holy trinity, her clit and her nipples formed a triangle of pure pleasure that brought her to intense, rolling, wavelike orgasm. It came crashing around her, she was drowned in it. Her breath stopped for an instant and she stared into nothingness. She floated for a second on the crescendo of pulsing rapture, as though she was at the bottom of the deep ocean. And then she breathed out. Her whole body was electric. She felt like she had completely melted. Her mind was free.Except… she HAD. We made it almost a kilometer down the river before our lungs started to burn, forcing us to return to the surface. We ran back along the canyon, naked bodies drying in the heat, all the way to the base of the falls. Mother, still waiting at the top, was furious.I was never sure if the night-march to the falls was intended to tire us out for the rest of the day. If that was our mother’s plan, it failed abysmally.It was dusk. We were sitting on the blanket together, me behind Zuri, our mother. My brain registers that the bear is hurting me, causing damage, but my body seems to know where this is going and has shut down my pain centers and turned up my pleasure centers. I am ashamed that this is the BEST sex I have EVER had, I'm cumming on this bears cock almost continuously at this point, and part of me is sad that this is most likely the last sex I will ever have. Barry is hitting all the right spots at about this point and I am beyond caring sadly, " oh God, fuck yeah, tear me.
