Ever since I turned 18, it has been the most amazing months of my life! My sister knew I was a sissy and taught me how to dress, act and be a woman. By now, whenever I am dressed, no one would know what is really hanging between my legs. I look completely pretty and feminine.
Last night was the best. With our parents out of town, Dad on business and Mom visiting her sister, Becca and I had the house to ourselves. We acted and played like lesbian lovers and last night my sister took my virginity. Then in the morning I woke up to her sucking my cock. I came hard in her mouth and she crawled up my body and shared a very intimate cum soaked kiss. As we left the bedroom, me in my nightie, knickers, garters, stockings and heels with my bra stuffed with 36C silicone tits and my sister naked except for her stockings and garters; we opened the door and there stood our mother!
I was shocked and tried to speak; but no words came out, my naked sister must have been humiliated and turned away from us both.
"What do we have here? Seems like I have 2 daughters now, and one of them a proper sissy!"
"Mum I am sorry...I just don't know what to say!
Mum said "Put your hands on top of your head and let me see what kind of a sissy I have in the family."
I did as I was told I felt my nightie hike up exposing my knickers, stockings and garters. I looked at Becca who still had her back to us. She must have been crying because I saw her shoulders going up and down.
Mum said "I have to admit, you do look good as a girl Julie."
I did not know what to think, but then I realized, she called me by my fem name - Julie. How could she have known that?
"Mum, only Becca has ever called me Julie. How could you have possibly known?"
Becca finally turned around and I saw she was not crying at all, instead she was trying to cover up the fact that she was laughing.
Becca turned towards me and said with a smile "She knows, because this was all her idea!"
I was too shocked to speak, but Mum and Becca came over and we did a group hug.
"I have long suspected you were really a sissy Julie, so Becca and I planned the whole thing. I am so pleased to have another daughter now."
That is when I noticed that all my mother had on was a robe. She smiled and removed it and she was as naked as Becca was. She was in her 40's but still stunning. Like me, she had a bit of a belly, just barely noticeable, great tits at 36DD and her legs and arse was as good as young women like Becca and I.
I must have been embarrassed when Mum said "That's ok dear, it is just women here now. No need to cover up. The only reason why I make Becca cover up when you father is around is because we would fuck her first chance he gets."
I noticed Becca look away, but I did not comment on it.
