Last night I heard my brother announce he was going to take a shower and if anyone needed to use the rest room, use the one downstairs. I thought, "ha, I'm gonna sneak in there with him after he gets all wet and soapy and have some fun." Then I got a phone call from my BFF so I went to sneak in a little later than I had planned. I quietly eased myself through the door and started into the steam-filled bathroom when I heard a woman's voice, and the unmistakable sound of my brother's moan of ecstasy. I peered through the steam and saw the distinct silouettes of my brother and his large, erect cock being massaged by a woman with a bountiful bosom I shockingly realized was mom! My mind shrieked and would have come out my mouth had I not used every ounce of will power to keep my mouth shut. I carefully eased back out the door and rapidly returned to my room. My own mother! OMG! I was dumbfounded. What if dad finds out? I thought. What if mom finds out I know? I wanted to find out.
