My sister, who recently moved across the street, was changing clothes while drawing the curtains! I was admiring her large breasts popping out from her bra when our eyes met! I thought she would be angry, but she just smiled gently. Oh, maybe things aren't so bad… I was peeping at my sister and masturbating when one day I found a bra in my room that looked like hers! Had the clothes been blown away by the wind? When I went to deliver it to my sister's house, she let me into her room, and we could make love immediately—it was a divine development! Then, massaging my sister's breasts, our lovemaking days began.
