My wife got home around five thirty from work. Fiona my step daughter arrived at four with my two step grandchildren. Luckily both were asleep when they got here for the first forty minutes, giving Fiona and I more than enough time to have sex.
The moment she settled the kids, she stripped naked, had me remove my shorts and boxers, then Fiona went down on me. It's something we've been doing for nine years, since I first fucked her when she was twenty three.
Once my cock was rock hard, which didn't take long, Fiona knelt down and presented her arsehole and pussy to me. Turning her head she said we'd better make it a quickie, then added "Pink or brown, your choice". Kneeling behind her, I slid my cock straight into her already soaking wet pussy.
I fucked her pussy as hard as I could, just the way she likes me to fuck her, and something her husband never does. Then once I had her moaning, I withdrew and eased my cock up her bum. Fiona freaked with lust telling me "Give it to me you dirty bastard". Fucking her like you'd fuck a common slut, I buried my cock up her arsehole, until she screamed out orgasming on my dick. Her shuddering made her rear hole clamp around my cock and it let go. I spunked every drop up my step daughters arse, and didn't she just love it.
By the time my wife git home, we'd fed the kids and were playing in the back garden. Fiona gave me a look and mouthed "It's leaking out of my bum". I grinned as she took herself off to the toilet. Following her as her mother watched the little ones, I joined her in the bathroom and had Fiona lick and suck on my cock. It might have been the situation or me just being super horny, but I busted my nut for the second time right down her throat.
Fiona and the kids left an hour ago. The hug we gave each other was one of a step father and step daughter as my wife looked on. What she missed, was me gently squeezing Fiona's right breast. Right now my wife is in the bath, giving me time bro type this, and also giving me time to text Fiona. We've just arranged for me to call by to her home during my lunch break in two days time. It'll be a whole hour if sex, as the kids will be at one of the other grandparents.
Fiona's literally just text back. It reads "So fucking horny for your cock, can't wait until Friday x Fiona xxx".
Roll on Friday, I say.
