Do you remember her, the Latina with the big hooters? The Beta Phi's called her "Torpedo" Lopez?" I nodded "She introduced me to a word that helped yo...u and I stay friends although Lisa still didn't like it."I looked puzzled and asked "What word?" Okay so I'm dense sometimes, so shoot me. She smiled at me and said "Bisexual." Then it made sense. I had thought she was gay but she was bisexual. She had begun openly dating girls shortly after Lisa and I became exclusive. When that happened, Lisa. “It was called, ‘I’m my sister’s pee whore.”“Omg!” I said, “is that the story about the sister selling her sister out for others can pee on her?”“That’s the one. And You wrote, I wish my twin sister would dominate me like the sister in your story did, it was a great story.”“Please don’t tell anyone I like stories like that!” I said.“I wouldn’t do that to you Sara, as long as you do as I tell you for now on, and no one will know but us. And I know you do more than like the stories, you do it. I alternately would suck her clit, her pussy lips, and then use my tongue again while trying to catch a gulp of air as her entire weight humped against my face.Her juices began to flow in volumes making me have to swallow, while she continued to suck me off.She pumped on my face for a good fifteen minutes and I did my best to match her flow and ebbs. Then she started to cum, smashing her crotch hard onto my face as her orgasm came to a climax. Thought I was going experience a broken jaw right. After dinner, I took Jan to bed, I tried ass fuck, she said it is painful, I turned her around slapped her face few times and gave her pussy fuck which she enjoyed much, she said the slaps are like adding spices and also gave a sense of being submissive... The next day after school she arrived accompanied by Sonia, I wanted to leave them alone. I told Jan if it is ok for me to go to the tennis club and pay my subscription, I will be back in about one hour, she said ok and Sonia said she will.
