Dick and Sally were in his room, having a secret meeting. She arrived early before Dick's sister Jane would come home so they could hang out for a bit, just the two of them. She was sitting on his bed and gently stroked his hair while he laid his head on her lap. They talked about random stuff.
"I want to have sex with you," Sally suddenly said.
"What, right now?" Dick asked.
"No, I want to do it with Jane in the room, unaware of us doing it," Sally said.
"Ok, that's impossible," Dick replied.
"Alright!" Jane said, "Challenge accepted. Let's brain storm ideas."
"Hmm," Dick started, "You are looking over the back of the sofa and I take you from behind."
"I don't think that'll work," she said, "Why would I lean over the sofa like that for long enough. Nice thought though. How about we go swimming and you fuck me under water?"
Dick didn't reply. He just stared into infinity, re-living the air mattress incident. The horror! Sally realised why that was a bad idea and quickly proposed something else.
"Jane could use her VR headset and we do it right next to her," she suggested.
"Nah, we kinda done that already," he said, "I don't want our sex life to become ordinary, repetitive and boring."
They both burst into laughter for a while and then started to come up with more realistic scenarios. Sally kept one idea to herself, she wanted to surprise Dick with it. When Jane arrived, Sally left Dick's room and spent the evening with her best friend, leaving Dick to play games and read.
Later that week, on Thursday, Sally texted him in the morning:
"Hi Casanova. Cum to mine at 7 2nite. Don't tell Sis. Big secret!!!"
Strange. Jane never mentioned going to Sally's that day. So how would this help with the challenge they had set themselves? Dick left the house, pretending to go to the cinema and rang Sally's bell. She opened at let him in, her parents were out.
"So, what's happening?" he asked, "Is Jane coming as well?"
"No," Sally replied, "I have a little surprise for you."
Dick loved her surprises more than anything. He had no idea what she had planned and the tension made him tingle with anticipation. She led him to her room where her laptop was placed on top of the low coffee table.
"Remove all your clothes!" she commanded.
"Yes, mistress!" he replied and did as he was told. His little penis was slowly getting hard from the anticipation.
"Now, lay down on your back, your head and chest under the table," she said.
Again, he obliged. When he watched her removing her panties from under her skirt, Dick got a little bit harder. Then, Sally sat on him, her pussy on top of his hardening little cock.
"So, what is this going to be?" asked Dick.
Instead of an answer, Sally made a skype call on her laptop. After just a few seconds of ringing, Dick heard his sister's voice form the speakers.
"Hi bestie! How's things?" Janes asked.
"Couldn't be better!" Sally replied.
