Getting to know my new family Ch4

This story happened a few months after that eventful weekend my parents were away (as described in Ch 1,2 and 3.)
One evening I returned home from work at about 5pm, when I got in my Step-mum Kate was doing some house cleaning she was up a ladder, dusting some cobwebs from the roof and she as wearing a skirt. I caught a quick glimpse of her ass; she was wearing a pair of red lacy panties. My Father had been out of town for the last week on business but was meant to return that night, so Kate was busy tidying.
Just then the phone rang and I answered it.
Kate: Whos that John?
Me: Its Emma she wants to talk to you.
Kate got down of the ladder and spoke to her daughter. I went into the kitchen and grabbed a soda. A few minutes later Kate came in.
Me: What did Emma want?
Kate: Nothing much she is staying over in Janet’s house tonight they have some project to work on.
“Some lucky b**tard is gonna get luck tonight” I thought to myself remembering the last project them two girls worked on.(See Ch3)
My Da wasn’t due back till 12 and Kate had to go to take a class at the gym until 8. She said she would be back at 8:30 for a quick shower and change and then we would go pick up my da. She left for the gym and I sat down to watch TV. About 2 hours later the phone rang again. This time it was my Da his flight had been cancelled due to bad weather and he had to stay another night in New York. He would be back at 4pm tomorrow and he told me to give Kate and Emma his love.
An hour later Kate got back and I told her the news. She was gutted, as she was really looking forward to seeing her husband after he’d been away for a week.
Kate: Fuck that anyway, I was really looking forward to seeing him again
Me: Yeah me too, I missed having another male about the house for the past few days.
Kate: Yeah, I was gonna cook that chicken for when he got back, but as its just me and you I think we’ll just order a pizza
10 minutes later the pizza arrived and we sat down in front of the Tele to watch Friends and eat the pizza. We sat watching the TV and chatted for the next few hours till about 12.
Me: There isn’t anything worth watching so I think I’ll head to bed.
Kate: Good idea, I think I’ll have a bath first, so will you hurry up and finish in the bathroom.
I ran upstairs and used the bathroom, I then went into my room, which was next door to the bathroom, striped off to my white boxers, jumped in the bed and began to read my book.
About 5mins later, I heard Kate go into the bathroom and start to run a bath. I started go get horny as I thought of my fine naked Step-mum bathing in the next room. But I quickly shook this thought from my head and returned to my book.
I continued reading for another 5 minutes or so, then I hit the light switch and began to drift off to sleep. But just as I was starting to sleep, I heard Kate call me from the bathroom.
Kate: John are you still awake?
Me: Yes, what is wrong?
Kate: I forgot to bring a towel with me. Be a dear and go and fetch me one in my wardrobe.
Me: Yeah ok then, hold on a sec.
I jumped out of bed and pulled a T-shirt over my head. I then grabbed a towel from the wardrobe and returned to the bathroom door. I knocked on the door.
Me: Right Ma I’ve got the towel where shall I leave it?
Kate: Am! Could you leave it into me in here please.
I froze and thought about being in the same room as my naked bathing step-mum.
Kate: John is you still there?
Me: Yeah I’m here.
Kate: Well could you please bring me my towel, the door isn’t locked.
I pushed the door open and walked in immediately my eyes fell on the fine women sitting in the bath.
Kate: Could you hang it on the railing over here.
I walked towards her trying my best to hide the bulge, which was forming in my boxers. I reached over to hang the towel, but the floor around the bath was wet and slippery and my foot slipped and I fell forwards into the bath on top of my Step-mum.
I jumped out and slipped on the ground again.
Kate:(Giggling slightly) Are you ok John, I don’t mean to laugh but that should have been on You been Framed (A British camcorder funnies show). Are you hurt.
Me: Naw, I’m grand.
Kate; But your soaking wet, you had better get them clothes off and dry your self before you get a flu.
Suddenly she just stopped and I saw her eyes fix on my boxers. I looked down and saw that my white boxers were soaked though, and now almost completely transparent. My cock was sticking out like the pole in a tent and Kate was staring right at it.
She slipped left hand under the water and began to finger fuck herself, as she grabbed my 9.5 inter with her right hand.
Me: (Acting the innocent) Mum what are you doing?
Kate: Come on, don’t act the innocent with me I’ve seen you checking me out several times before, Especially when I’m sunbathing in my bikini or doing my exercises in my lycra.
At that she stood up pulled off my boxers and T-shirt and pulled me into the bath next to her.
Kate: I’ve also been checking you out from time to time. I’ve often seen you in that tight little Speedo’s of yours and I’ve fantasized about that package I could see in them.
She pushed me down in the bath and began to give me the best blowjob I’d ever had. For the next 10 mins she sucked and sucked on me. Then she bent over on all fours and stuck her ass in the air.
Kate: fuck me hard my darling Stepson, as hard as you can.
I grabbed a firm hold of her perfect ass stuck the whole length of my swollen horn up her ass and began fucking her as hard as I could. I could feel the water whirl around my ball bag as I gave my new Mum a good ass ramming. For the next 15mins, I fucked her hard until I felt the surge though my balls.
Me: I gonna cum.
Kate: Well we can’t waste that.
She pushed herself off me and stuck her mouth around my tip of my dick. 5 seconds later she had my entire load in her mouth, which she swollen up as I collapsed back in the water.
Kate: I’m not done with you yet.
She stood up over me in the bath and slid her wet pussy on top my face. I knew exactly what she wanted and began tongue fucking her. Se moaned outing pleasure, I grabbed her breasts and began flicking her nipples and squeezing her gigantic mounds. It wasn’t long before my dick was stood back up to attention, and upon seeing this Kate gave me a sexy grin and slid down my body licking my pecks, nipples and belly button as she did so.
She slip her pussy down onto my cock and began moving up and down my shaft as if my ball bag were a trampoline. I began playing with he mounds, as she moaned out. After 20 mins I felt that surge build up again and told My-step mum “Its nearly that time again”. But this time she didn’t move a mussel and took my full load inside her. We both then collapsed in the water.

We got out and began to dry and dress each other before she invited me into her room Saying she was lonely in the big kingsize bed. But I made sure she was well attended to, she then came to my room where we fucked yet again. The next morning I was taking a shower, when Kate joined me scrubbing me from head to toe, we then fucked one more time heading off to collect my Da. We both promised never to tell a living sole about that night.
However the real news came about a month later, when one day I returned home from work to be greeted by my Da with a huge smile on his face. “What are you so happy about” I asked. He told me that Kate was pregnant and that I was gonna have a new baby brother. But later that night when my Da was on the phone to his mum telling her the news, Kate told me that I wasn’t gonna have a brother, I was gonna have a Son. She said that she couldn’t break my Da’s heart and told him it was hiss but really, it was mine.
