I had a relationship with a boy at the time, not a sexual thing as that never interested me but one night when I came home my sister and her boyfriend...were having sex with the bedroom door open as I walked past.He was performing oral on her and I was immediately captivated, as I never had seen such an act and the way my sister clearly enjoyed it.Later when she and I were alone she asked me what I thought about, when I was spying on her, which embarrassed me, as I was not spying, just walking. Veena was closing the windows of the room. I could see her ass dancing when she was bolting the window. I smiled at her and said’veena,yen sakkathagide kane ninna thika'(veena,your ass is simply superb).She turned towards me and smiled at me. After closing the window, She came on the bed near my legs and parting my legs, stared at my cock and smiled again naughtily. I caught hold of my cock in my hand and smiled at her. All the while she was kind a biting her lips in ecstasy.She came near my. “Are you feeling okay?”Gary responded by placing his fingers under my chin, and gently lifting my face to kiss me.I resisted the urge to slide my hand over to to massage his penis. Tonight, I was committed to allowing my brother to advance this as slowly as he liked. Unlike when we were teenagers and I teased him and tempted him to do things he later came to regret, this time he would have to take the lead. If he wanted me tonight, he would have to take me.Gary slid his hand inside the bra of. Up till then the goodnight kisses did me just fine. Then one afternoon we had a quick lunch in my kitchen. Before she left for her evening waitress gig she mentioned how nice I’d been to her, and with a foxy little wink she told me how unnecessary that was now. I told her I didn’t want to make assumptions about a girl as nice as her. She said she made assumptions about me, said she assumed I like to have my cock sucked. I didn’t stop her from trying to prove that.That was a week or so ago..
