“Who else in this family have you fucked beside me and granddad?”
“No one.” We fucked again and fell asleep.

We were woken by the ringing of the doorbell.
“That’ll be Mark.” Lucy got up and calmly walked out of the bedroom and over to the front door. With her hand on the door handle ready to open it she looked through the spy hole. “It’s Susan.” She said and walked back into the room. Lucy put on her skirt and shirt and was searching the floor by the sofa. “I can’t find my bra and panties.”
I wrapped a towel around my waist and gave Lucy as long as I could before opening the door. “Hello. Come in. I was just about to have a shower.” I said.
Susan held out a bottle of wine as a welcome gift and I heard Mark come up the stairs behind her.
Turning into the room I saw Lucy’s panties lying next to the photographs. I dashed over and recovered them just before Susan and Mark came in. Lucy saw me take them into the kitchen.
“Where’s my bra?” Lucy mouthed.
“I don’t know.” I mouthed back.
My new neighbour and Mark sat together on the sofa. It was obvious they liked each other. As an excuse to stay longer Mark suggested Lucy take a shower before they drove home.
Lucy and I went into my bedroom. I left the door open for Mark’s benefit but Lucy closed it.
“Won’t Mark be suspicious.”
“Of course not.” Lucy said. I dropped my towel and Lucy took off her skirt and shirt and my penis became stiff at the sight of my sister’s beautiful naked body.
“I think you need a cold shower.” Lucy said.
“Or better still another fuck. Do you think our grandparents still have sex?”
“Ask them.”
“I can’t do that.”
“Yes you can. They trusted you with their erotic photographs.”
Lucy stepped into the shower cubicle. “Come in here with me.”
“What about Mark and my neighbour? They might hear us.”
“They’re flirting with each other they won’t hear us. Anyway Mark won’t mind. I’ve got a lot to tell you about Mark and me.”
“Were you telling the truth when you said that the other big penis you had was granddad’s?”
“Yes.”
“When did you and granddad have sex?” I assumed it was only the once.
“The first time, about six years ago. Mark and I wanted to spice up our sex life. I decided to get advice from nana and granddad because aunt Mandy said they were into that sort of thing.”
“So how did you and granddad come to have sex with each other?” I asked between kissing my sister’s beautiful breasts and sucking on her nipples.
“We went with them to a club. We agreed not tell anyone that I was their granddaughter. We met a couple they knew. They were a nice couple and we explained that this was our first time. The six of us went into a private room and the couple agreed that Mark and I could just watch if we did not want to take part.”
I was being turned on by what I was hearing and pushed the tip of my penis against her opening.
“The man was fucking nana and granddad was trying to fuck the woman but the woman was having difficulty taking his big penis.”
Lucy steadied herself by putting her arms around my neck. I pushed my penis into her and she eased herself down onto me.
