Gonzalo pushed me back against the tree trunk, placing one of his hands on my waist and with the other he began to caress my face. One of his legs slipped in-between mine, pushing them apart.
"Your face is flushed and your skin is warm," he said getting closer to my face and leaning his body against mine. I felt his erect cock pushing onto my exposed thighs.
His fingers brushed down my body and ended up gently stroking my inner thigh, threatening to touch my pussy.
"Tami, you know that if we do this now I'm not going to be able to stop, right? Allowing me to touch you like this and being this close to you makes it very hard for me to..." he whispered the next words into my ear, "...resist fucking you."
I clenched my teeth and responded, "I-I know you well enough to assure that. You're very impulsive."
"And you still want me to put my throbbing cock inside you, don't you?" He whispered and smiled with desire, getting his fingers closer to my crotch.
I began panting slightly and thinking to myself, 'This is not okay, we're siblings, he's married...'
I then tried to push him away but was unable to do so; he stood in place firmly. "We can't do this Gonzalo we're siblings, it's not okay," I said looking up at him almost crying due to frustration and anxiety.
He looked straight into my eyes and said, "Oh no Tami... of course we can. If we're responsible there's nothing to be afraid of. Plus, the lust in your eyes betrays your words."
I had no answer; my brother was right. I wanted him, his body... his cock. I looked down and grasped his shirt.
"Come on... spread your legs a little more," he said as he forced himself in-between my legs even more.
"Please..." Before I could finish my sentence, Gonzalo began sliding his middle finger along my wet slit, touching and teasing my clit, "Ah...ahhh." I grasped his shirt even tighter and allowed my forehead to bury itself on his chest.
