We lay for a while before Belinda sat up.
"We better get ourselves sorted before anyway comes home." She told me.
Reluctantly I agreed and we kissed once more before I went up to my bedroom, leaving Belinda to unlock and go to get a shower. Closing my bedroom door I collapsed on my bed and stared at the ceiling. I don't know how long I had been lying on my bed but I guessed I must have dozed off because, all of a sudden, a door slamming caused me to sit bolt upright. Listening carefully I could hear two voices, one male and one female, talking quietly.
Rising from the bed I walked to my door and, quietly, I opened it just enough to make out who the voices belonged to, Dad and Claire. They had taken a risk coming home at the same time and I stood listening to see what they said.
"Don't worry Claire your mum is obviously in bed." Dad whispered.
"What if she has heard us though, you didn't exactly close the door quietly." She responded.
"I'll just tell her that you rang me and asked for a lift home."
"Yeah but..."
"Stop panicking I can wrap your mum around my little finger." Dad said with a slight chuckle.
I had heard enough. I closed my door and got back on my bed. I couldn't believe my dad had changed into someone like that. He had never been like this with my mum, yet here he was married to a beautiful woman but screwing his step-daughter. I heard the two of them walking up the stairs, followed by more giggling, and then two doors open and close.
I finally closed my eyes and started to drift off to sleep when I heard yet another door click. I was about to sit up and listen when I felt a weight lower itself on to my bed. Unsure what to do I lay still and waited to see what happened next, I couldn't even imagine who it would be. Whoever it was started to shake me, gently at first, but gradually getting rougher. Still I lay there, hoping they would just leave, when a felt a hand start to creep across my naked thigh.
That touch was too much for me and my cock, which had started to stiffen rapidly, suddenly sprang to full length and I felt the fingers encircle me gently. There was no point me trying to hide the fact I was asleep any longer and I opened my eyes, to find myself staring at the tear streaked face of Belinda.
I was about to speak when she put a finger over my lips with her free hand and started to stroke my cock slowly.
"Just lay there and enjoy it." She said quietly.
"But I heard dad come in." I replied. "What's happened?"
"He just stripped off and collapsed on the bed."
