Our Little Secret Gracie-Part 2

Mark lifted his sister from him. She looked so satisfied, having felt his cock inside her. Her hair was ruffled from their frantic fucking, but it only added to her beauty. He could have laid there forever, just waiting for his cock to recover so he could fuck her again, but he was expecting his mum’s sister, Janet, to pop round this evening to check everything was OK. “Grace, Janet will be here soon, we better get dressed”

Grace stood from the bed, her pussy still tingling from the penetration of her brother’s thick cock. She didn’t really want to move, but she knew Mark was right-Janet would be here soon, and the last thing she wanted was to get caught on their first attempt. She walked to her wardrobe, and picked out some skinny jeans and a a halter neck top. She draped them over her desk chair, and rummaged through her drawers for some fresh underwear. As she dressed, Mark picked up his dressing gown, and pulled it on. He walked up behind Grace, and started to kiss the back of her neck, and cupped her breasts, which were now encased in her top. “Gracie…” he murmured, feeling himself become aroused already, “I can’t wait until later” Grace giggled as she felt her brother become semi erect and his cock push into her arse cheeks. “Neither can I Mark” she replied huskily, turning to kiss him full on the mouth. They stood like that for a few minutes, probing each other’s mouths with their tongues, before Mark pulled away to get dressed.

Janet walked through the back door without knocking, as she always did. She was pleasantly surprised the kids had managed to keep everything relatively tidy in their parents absence. She found Grace sat in the lounge, watching TV. She heard Mark put the telephone receiver down in the hall, and then he followed Janet into the lounge.”Hey” Janet said, and they both replied “Hi Janet”.
“Is everything OK, no problems?” Janet said, obviously in a rush. She had shopping to do, and kids to pick up from an after school club. She was glad that Grace and Mark seemed mature enough to take care of themselves. “Everything is just fine,” Mark said, to which Grace added “We have been getting on really well Jan, no need to worry.”
Janet seemed happy with this and said “well if you need anything, you know my number. I will nip back in a couple of days, OK?”, and with that she walked to the back door, followed by Mark and Grace, shouting “Bye” as she walked round the house and to her car on the drive.

Mark and Grace both listened for the car starting, and driving away. Grace deliberately walked to the back door, and turned the key.”Just in case”, she smiled, and then “what do you fancy for tea?”

Mark was glad that Janet wouldn’t be back for a few days. He and Grace would be able to have plenty of time to enjoy each other before their parents returned. He had all kinds of plans for Gracie, things he had never dared ask any of his girlfriends to do. But Grace had promised to keep quiet, and he was going to take full advantage of it.

He walked over to Grace, who was now rummaging aroung in the fridge, and slid his hands round her waist. He turned her around roughly, and kissed her, pushing her half into the fridge as he did so. He reached up behind her neck, and untied Gracie’s top. He pulled it down at the front, and felt her bare bra less breasts tumble out in front of him. She looked stunning, standing naked from the waist up with her skin tight jeans clinging to her every curve. “Mark” Grace said, sounding alarmed. “Mark, there is someone at the window.” Mark stopped what he was doing, and half froze.
