"Yes, they smell delicious. Thank you."
Gabriella gives Bradley a kiss and sits next to him. Her hand immediately goes over his shorts and rests on his dick. He looks at her, with a "what the hell are you doing? My sister is right over there" stare, and she just smiles, slowly moving her hands along his dick, over the fabric of his shorts. He tries to push her hand away, but she just keeps on doing it. She slides her hands under his shorts and starts rubbing his dick, which is slowly getting harder.
Bradley can see that Gabriella is turned on by all this, her nipples hard. She's squeezing her thighs together, trying to rub them to get some friction. He sees and places his hand on her thigh. She stops working his dick and gives out a small moan. Looking towards the stove, he sees that Kate has her back to them, and she's not looking. If she does turn around, he knew they would just stop. He slides his hands along her thighs and touches her pussy. She's wet, and the panties are wet. He rubs her pussy over the fabric, the extra layer giving more stimulation to her clitoris, as she's jerking him off.
If Kate turned around at this moment, she would see her brother's dick being fondled by Gabriella, and she being fingered by her brother. He slides one of his hands up her shirt, fondling on her breasts, and she lets out a moan. This is when Kate turns around, and sees what's happening.
"What the fuck! What are you doing?" she screams, but she can't take her eyes off her brother's dick. Bradley immediately takes his hands off her, but Gabriella is slow to do that. Her hand is still on his dick, and Kate is just staring at it. When she's silent for a few more seconds, Gabriella gives his dick one last pump, and bend to kiss it on the head. She straightens herself up, smiling.
"Are the pancakes ready yet, Kate?" she asks, being all glib. Kate just looks at her incredulously.
"Get up."
"What?"
"I said, get up," Kate says, walking around the table to their side. Bradley's dick is still out of his shorts, and it's slowly getting less hard. He's scared about what is going to happen next, as his girlfriend and his sister look each other in the eye. What happens next is something that surprises not just him but Gabriella too.
Kate leans forward and kisses Gabriella, one hand going to her hard nipples, the other going to her wet pussy.
"Will you share him with me?"
