My twins

My name is Martin and I am dad to young teenage twins Josh and steph. My wife was called away for a few days because her father had been taken ill and she had to take care of him and her mother who were both very elderly.

The twins were old enough to take themselves backwards and forwards to school so all I had to do was keep the house in order and cook some meals. I took a week off from work to make things easier.

This particular night I was woken up by I don't know what. I lay there in the dark I thought I heard whispering. I got up to investigate and listened outside Josh's bedroom door. It was completely silent so I quietly opened the door and peeked in. His bed was empty and I thought that he had just gone to the toilet as the toilet light was on.

After a few seconds and Josh not returning to his bed I walked in. They have a 'Jack & Jill' bathroom which they both share and as I walked towards it I could see the Steph's door on her side of the bathroom was also open.

As the bed came into view I could see them both laying on the bed, Josh in his boxers and Steph in a big t/shirt which she normally wore for bed. The thing that shocked me was that they were kissing each other and I could see that Josh's hand was underneath the hem of  her t/shirt and he appeared to be  fondling her.

Josh lifted the hem of the t/shirt higher and I could see that Steph was wearing a pair of tiny panties. Josh was sliding his finger up and down her crack through the material and she appeared to be enjoying every minute of it. Josh took hold of the panties and pulled them off revealing her hairless crack which he continued to  stroke dipping his finger deeper.

I could see Josh had a massive erection. I was completely hard by this time looking at the scene before me. I edged closer and pushed Steph's bathroom door open. The light illuminated the bed completely and they both sat up shocked to see me standing there in just my boxers.

They both started to scramble off of the bed but I told them to stay where they were. They were both sitting there with petrified looks on their faces as I walked up to the foot of the bed and climbed up between them and lay on my back.

I had my to my sides  and indicated that they should lay back down again. When they did so I pulled Steph's  t/shirt up once more and started to finger her at the same time I slipped my hand inside Josh's boxers and took told of his cock which had now deflated.

After  a couple of minutes I felt josh's cock start to harden and Steph was definitely getting moist. I took my finger from Steph's moist slit, took hold of her hand placed it on the bulge in my boxers. I rubbed her hand up and down my shaft making my cock ooze precum.

Josh was watching Stephs hand move up and down my shaft and I could feel his cock twitching in my hand. Josh leaned over and slipped his hand inside my boxers and felt along my shaft. At this point I slipped off my boxers and let my throbbing cock spring upward for them both to see.

I turned toward Josh and pushed down his boxers revealing a mass of pubic hair. which I ran my fingers through. I then turned to Steph and told her to sit up and I took hold of her t/shirt and pulled it over her head. Her young pert breasts were beautiful with large puffy nipples.

I put my arm around Josh's shoulders and pulled him on top of me our cocks sliding against each other. I changed places with him so that he was now next to Steph. I took hold of his hand and caressed her body with it making sure particular attention was made to those lovely breasts.

I pushed his head down and he clamped his lips onto one of her nipples. I moved him across so that he was laying on top of her with his knees either side of her hips. I knelt between Steph's legs and tongued her pussy making her gasp with pleasure. Before my face was Josh's throbbing shaft which I couldn't help licking from the tip to his balls and to his hole. He gasped when I pushed my tongue in and moved it about.

Josh's cock was leaking a lot so I took hold of it and lined it up with Steph's cunt and pushed him forward. He slid straight in. I took hold of his hips and  after placing my mouth over his hole manipulated him backwards and forwards his cock impaling her cunt and my tongue impaling his hole.
