Well, I had now fucked both of my stepdaughters, not on my instigation either, without my wife finding out, as all hell would be let loose if she did. Five months after our Spanish holiday Sally had her twenty-first birthday, she was getting more like her mum every day in looks and ways. Jane had been promoted at work, which would mean that sometimes she had to attend meetings in other offices, which involved her stopping away from home for at least one night.
One week she told me that she would be away for two days later that week due to a meeting in Scotland that would mean her travelling up the day before and then coming back the next day. She would have to leave on Thursday and would be back by Saturday afternoon.
After Jane left, I did some jobs in the garden, then as I was feeling tired, I got into bed to have a few hours sleep, I dropped off straight away into the land of nod. I awoke later on to the feeling of my hardening cock being stroked very gently.
I thought that Jane had returned for some reason. I then felt a second hand on my cock and a mouth on the tip. I was awake fully now and I looked down towards my crotch to see two bodies fully under the covers, one on either side of me. I realised that it could only be Sally and Mary, who I had fucked previously on their own. Now it looked like they were taking advantage of their mother being away to get me to fuck them both together this time.
"Right you two stop that, this instant," I told them.
"No, we won't," said Mary, "mums not here so we are both going to be fucked by you again."
"Both of you together at the same time," I was panicking slightly as I never have had a threesome.
"Yes that's right daddy both of us, an incest threesome...nice and dirty," moaned Sally.
"What makes you think I can last long enough to be able to fuck both of you and that I can cum twice in a short time."
"Who said about a short time, we have two nights alone." As it was Mary talking I knew it was Sally who was taking my cock into the back of her throat and humming, where she learnt to do that I don't know. I knew that there was no use in fighting them both, if they wanted it, they were going to get it, if I wanted it or not.
"Ok, it looks like I haven't got a choice, get up here Mary."
Mary threw the covers off of me and I saw that they were both naked except for Black stockings and suspenders. Mary crawled up to me and I took her head in my hands and gave her a wet kiss on her lips, she opened her mouth and put her tongue into my mouth and wiggled it playing with my tongue.
"Mmnnnn that's nice daddy I love you." Due to Sally's administration of my cock it was now hard. I now had hold of Mary's breasts one in each hand jiggling them about and catching the nipples in between my fingers making her moan and squirm about.
"Ok swap over girls." Mary went down and sucked my cock while she held her ass high in the air by my shoulder so I put two of my fingers into her and finger fucked her as Sally came and started kissing me all over my mouth.
"I love you too daddy and have wanted another fuck for ages."
"I don't know darling. I still don't know if this is right, doing it behind your mum's back, she will kill all of us when she finds out," I said.
"I doubt it, 'cos I think she knows," said Sally
