Jess is a tease

Jess came out from the kitchen with her glass filled with ice cold water with that evil grin I'd seen thousands of times. I sat there wondering what she'd hatched up whilst she was in there. She walked over to the chair Sam was sitting on, and sat down on the arm to join us watching the TV.

He looked nervous, his eyes glued to the TV. I guess having two scantily clad young women wandering around was having an effect on him.

I looked over as Jess drank from her glass, her shirt was long enough to cover her backside but when she raised her arm to drink she was exposing the top of her cheeks and butt crack. She does have a habit of teasing boys in subtle ways but I don't think she was doing it intentionally this time. As I was watching her I saw his head shifting to the right slightly to get a better view but not blatantly.

"Oh you're making me thirsty now Jess, can you get me a glass please?" Mum said.

I guess I wasn't the only one that was watching her.

"Me too if you wouldn't mind." said Kate.

"Of course." she said as she stood up and bent over to put her glass down on the coffee table. She had to walk right in front of Sam to get to the coffee table so I can't blame him for looking. The panties she was wearing were purple but the colour had faded away because they were years old now. They even had a few holes in them. They weren't very big, none more than the size of a penny, but they gave us a forbidden peek at the bare skin on her arse cheeks.

I honestly couldn't believe she'd done that. I don't think either of our mums had noticed because neither of them said anything but I definitely did, and so did Sam. He must've felt my eyes on him because he glanced over at me, our eyes meeting. I felt his embarrassment. It looked like he wasn't completely shameless after all. Still, as soon as I looked away he went right back to her bum.

She walked towards the kitchen but unexpectedly turned around. "Do you want a drink Sam?" She had absolutely caught him staring. She smirked and fidgeted with the hem of her shirt as she waited for his reply.

"Uh.. sure." He stammered, his guilty eyes dropping to the floor.

"I'll get you one too Sarah." She added, throwing a grin at me before returning to the kitchen.

I wasn't even thirsty, but I didn't want to seem rude in front of Kate. Fine, I thought. I'll just take a few sips and set it down.
