Jessica got home and they had a normal family afternoon around the house. Sarah didnt let on but could tell that Jessica couldn't wait to feel James' cock slide into her pussy.
After dinner, James suggested a family movie night, winking at Jessica. Everyone agreed.
They all went up to change. Jessica went into her room, shut the door, stripped and put on a long t-shirt with no panties. She wanted to be easily accessible for James.
James entered his room, stripped, put on boxers and a t-shirt and slid his cock into the glory hole. Jessica knelt and immediately swallowed as much of his cock as she could. She heard James moan quietly and smiled. She loved pleasuring her brother.
Sarah changed into lacy, see-through panties and a t-shirt. Before going downstairs, she peeked in on James. His pelvis was glued to the wall. Sarah quietly approached and heard distinct sucking sounds from her daughter's side of the wall. Sarah's pussy gushed. She fondled her son's cum-filled balls while he fucked her daughter's mouth. James slid his hand in Sarah's panties and rubbed her clit. They kissed. They were having a threesome without Jessica knowing it. Sarah broke the kiss, smiled at her son, winked and headed for the stairs. "Are you kids coming?" she yelled. "In a minute!" James responded.
Sarah went to her recliner and covered herself with a blanket.
Jessica released her brother's penis from between her lips. They met in the hall and kissed. "I would have answered mom too, but my mouth was full." Jessica exclaimed with a smile.
They headed downstairs with a blanket and set up on the couch as they had before, with James having access to his sister's horny, wet pussy without their mom being able to see.
"I hope you kids don't mind, I've been having trouble sleeping, so my doctor gave me some pills. If I fall asleep just leave me here tonight." Sarah informed them.
The kids gave each other an excited look. They turned out the lights and started the movie.
After a few minutes James slid his hand slowly up Jessica's leg to her pussy. He ran his fingers through her pubic hair before focusing on gently rubbing her clit in circles. Jessica tried to control her breathing, and it took all her willpower not to thrust her hips into her brother's hand. Then it struck her; mom might already be knocked out. "Mom? How're you doing with that medicine?" No response. "Mom?" a little louder-nothing.
Jessica got up and saw her mom's eyes shut and breathing steady. She shook her mom-no movement. Sarah was out as far as Jessica was concerned.
James stood beside his sister. He lifted his mom's arm and dropped it. It was limp.
"Should we turn off the TV and go to my room?" Jessica asked.
"I have a kinkier idea!" James replied. With that, he turned on the light, took off his clothes and said "suck my cock, sis!". Jessica was nervous but incredibly horny. She knelt and gobbled her brother's erection all the way to her throat and proceeded to mouth fuck him just two feet from her mother. James started talking dirty to her which made her wetter than she'd ever been. "Yeah, suck your brother's hard cock you little slut. You like doing this in front of mom don't you? I bet you wish she was awake to watch you? I bet you want her to finger you and lick my balls while I shoot my cum in your hot little mouth!"
