"You're having sex with your brother, aren't you?" I was taken aback when my brother's girlfriend suddenly asked me. In revenge for being cuckolded, she fingered my pussy and I couldn't help but feel pleasure. Perhaps she knew how good it felt, because the next day, on a day when my brother was away, I was made to experience a new pleasure. He licked me with his pointed tongue while I was in a spread-eagle position. He rubbed my labia minora and labia majora together vigorously in a tribadism position. We pressed our vaginal walls against each other with a double-headed vibrator, bringing us to the edge of ecstasy. It was a very intense first lesbian sex that excited me more than my brother.
