I have a twin sister about 10 minutes older than I am. When she and my mom are out I sneak into her room and get 1 of her bras and panty out of her hamper. I put them on and lay on her bed. At first I just wanted to imagine what it would be like to be her, but now I lay there thinking of her. I smell her perfume on her pillow and start rubbing my cock. I want to feel her lips on my hard cock, and then my load blow into her mouth, watch her swallow my cum. Her sweet pussy would feel so great on my shaft, and my cock would stretch her tight ass.
