.. I...” Humiliation rippled through me. I was naked in front of my mom and sister. I grabbed my cock, trying to hide it.“I never once spanked you...” my mother growled, advancing on me. “I should have. I should have whipped your ass raw. I'm your MOTHER! What did I do wrong that you would say something like that to me? Think that was at all okay to say?”She was almost at me. I squirmed. What went wrong? Was it because I stole the panties? Tears brimmed in my eyes. My mother lunged at me with her. So, not really giving it much thought, even though this was completely out of character for her, I walked over and said hello. I didn’t really know what she wanted or what to say so I simply said “Off to another birthday party huh?”She smiled and said “Yes, got to go entertain the kids this afternoon, got two parties booked”I said “two in one day, that’s a lot of moving around and work isn’t it?She said “Yes, but its only two hours each and I’ll be done by five tonight”I couldn’t help it, I. One more stroke and I was over the edge. She must have felt my cock pulsate, and shoved forward, the last bit of my prick vanishing, and I began to unload straight down her throat.Pulse, pulse, pulse, my groin convulsed as I poured wave after wave of cum into her mouth. Marilyn took it all, backing off at last, her nostrils flaring as she drew in a breath, catching the last few spurts on her tongue. The gentle touch of her fingers on my balls made my groin wring itself dry with a final ecstatic. This is a gender game. Everyone having their respective roll in it and participating well to their performance… Train started as per the schedule and I observed my co passengers looking around. Two ladies on lower berths and rest are men. Some seats are vacant. I looked at the ladies and offer a friendly look. They too responded positively. In the talks I came to understand that they are mother and daughter.Mother is so good with huge boobs and quite a big ass. Daughter is tall and having small.
