The Competition

My sister Lyra is having her best friend, Adria, over for a sleepover. I try not to notice how obsessed with Adria that I am, but I can't help it. Lyra is teaching Adria how to dance in the living room and I am trying to play it cool. I've got a major hard on watching my sister teach her how to seductively move her body to the music. Oh no.. she's looking at me. "I need you to teach her how to slow dance," she tells me. She wraps my arms around Adria and she shows us how to move. I'm so close that I can feel the warmth of her exhale. Lyra leaves the room to grab a drink. Adria steps on my toe with her heel, and she's embarrassed. I pull her into my arms and my chest is touching her breasts, I can feel them right through my t-shirt. My heart is racing as I inch closer to her lips, she is moving closer to mine and we meet with a kiss. Lyra comes in, shocked and angry! She orders her friend to leave the house, but I remind her gently that no one is around to come pick her up. Adria apologizes and rushes up the stairs. I tell my sister that she was "out of line," and my sister nails me down to the sofa. "Out of line?! Who are YOU to tell me that I am out of line." She begins to list off the qualities that Adria has that are not compatible for me. She's flustered, her eyes are filled with tears, and I grab her hand affectionately. She kisses me abruptly. I taste her mouth, and I kiss her back.. my hands are paralyzed. I'm turned on. I'm terrified. She wants me all to herself. Adria sneaks down the stairs and watches, she touches her pussy as she watches my sister straddle and grind on top of my lap. Her heel makes a noise and we look at her. Adria is mortified and runs up the stairs, "wait," I call out to her! Adria creeps down the stairs, hesitantly. Watch the story unfold..
