When I got home, she was waiting to give me a birthday hug. As she hugged me, she pressed her tits hard against my chest and kissed me on the neck jus... below my ear. For the first time ever, I felt a little aroused by my sister. When it was done, I excused myself to go change my clothes and wait for mom to get home.Bambi had arranged her schedule so she had the night off. She had fixed a wonderful dinner for me. As it was my birthday, mom allowed both my sister and I to have some wine with. Rebecca burned with lust. Her hips began to buck against Luke. Her vagina was completely lubricated, budding like a rose and felt so hot. She unlocked her legs and Luke let her gently drop to standing on the water-covered, tiled floor. Rebecca moved to stand with her back against the wall, her eyes burning with lust and she wantonly rubbed her pussy, parting her labia, exposing herself to her young lover. Luke didn't need telling twice. He surged forwards and pressed himself dominantly against. With hesitation I rolled over exposing myself and my full blown erection. As my eyes adjusted to the light I saw the two of you staring at me and grinning. At this point Jenn said I’ll start with the shoulders as she repositioned herself at my head and I had the most perfect view of her swaying breasts as you started with my legs and thighs. It did not take long for your hands to find my manhood and caress it slightly which made my head tilt back and mouth open slightly teasing Jenn’s nipples. My nipples feel erect and I know will be visible against the material.I open my legs and raise my skirt up my thighs to a point where anyone looking might be lucky and catch a glimpse of my wet pussy.I can see that hubby approves from a bulge straining against thin lightweight summer trousers.The thought of what we will do later makes me feel sensationalAs I glance around, I notice another guy good looking mature on his own at a table perfectly positioned to watch my exhibitionThis excites me.
