Saturday morning. Jason woke up. His bedroom door was open and he could hear his sister talking to someone in her bedroom down the hall. Probably her friend Julie. Julie had red wavy hair, a fun personality, and a sexy attitude. He hoped it was her.
They no doubt had gotten home late last night, possibly drunk, and were likely still in bed. Julie probably crashed for the night instead of arriving home drunk. At eighteen, they weren't legally able to buy alcohol, but they probably found a party or something somewhere and managed to over-do it. Hopefully they took an Uber home.
Jason had awakened with a hard-on even before he started thinking about his sister's friend. He pushed his covers down and started lightly stroking himself, his hand inside his boxers. He heard someone coming from down the hall.
It was Julie. She walked past his door, probably on her way to the bathroom. She was wearing a small sequined top from the night before, and a pair of very brief panties. Even in the short time it took for her to pass his open door he was able to get a good look at her curvy ass through her sheer underwear.
His cock responded.
A moment later he could hear the sound of her peeing. It sounded like she had left the bathroom door open. Typical Julie. He gave his cock a couple more strokes and then withdrew his hand before she returned. His cock stayed hard.
Coming back from the bathroom, Julie paused at Jason's door. She looked in, giving him a perky 'Hi'.
He couldn't help but stare at the curly red pubic hair visible through her sheer panties.
She in turn looked at the obvious erection visible in his boxers. She raised a questioning eyebrow and made a 'jerking off' gesture with her hand. Rather than deny it, he just gave her a slight shrug. She then lifted her top revealing her tits to him. She wagged her hips, let him stare for a moment, and then let the top fall back down. She said 'bye', and returned to his sister's room.
She was such a tease. Jason resumed his light masturbation, now with an image to spur him on.
A minute later his cock was becoming quite hard, and his pleasure growing, when he was interrupted by his sister calling out, "Jason. Bring us some coffee! We're desperate!"
He paused masturbating. "You can get it yourself can't you?"
"We don't want to get out of bed. Please?"
Julie added "Your sister will show you her tits."
Jason could hear his sister slap Julie's shoulder. "I will not!" Then to him "Julie will show you
her
tits."
"I already did. It's your turn."
"You already did? You are such a slut sometimes."
His sister continued, "Jason. We need coffee. We're hung-over. Bring us some coffee and someone will show you their tits. Probably. OK?"
"OK. Hang on." He got out of bed wearing a t-shirt and his boxers. He padded downstairs to the kitchen.
Fortunately, he had set the coffee timer last night to brew this morning, so it was already prepared. He filled two mugs and placed them on a tray. He added a small carton of milk, then realized what they really needed.
The two girls were still in Amy's bed, though not under the covers, when Jason entered. His sister Amy was wearing a pajama top that buttoned in front. She was also wearing a pair of dark red lacy panties. Julie still wore the sequined top and sheer panties he had seen her in earlier.
He put the tray down on the bedside table.
"Coffee. Milk. And I brought this." He held up a bottle. "Mom's brandy. Might help your hangovers."
Julie responded "Oh God! You're the best! Yes, brandy and coffee please."
Amy added "Thank you big brother! Me too"
Jason looked at them. "Where are the tits I was promised?"
Amy and Julie looked at each other.
Amy said to Julie "I'm his sister. He doesn't want to see
my
tits. Show him yours."
"He already saw mine. I'll bet he
would
like to see your tits. Wouldn't you Jason?" They both looked to him for a response.
Jason wasn't ready to answer that question. Instead he laughed and said "That's all right. No one has to show me their tits. Enjoy your laced coffee." He started to leave the room. His cock still needed attention.
Julie stopped him. "No. A deal's a deal." She lifted her top over her head and threw it on the bed. She was now topless revealing her lovely tits to Jason again. "I needed to change out of those anyway." She smiled at Jason and took a drink from her mug. So sexy.
Jason thought that her tits were beautiful. Perfectly shaped. Nipples that looked so suck-able. He was now uncomfortable knowing how obvious his hard-on was becoming. He was in danger of it popping out the opening in his boxers. He should probably leave so he could finish the masturbation he had started earlier. But he really was enjoying seeing Julie topless.
His sister interrupted his thoughts. "Jason, go down and bring up the coffee pot. And bring yourself a mug."
"OK." He headed down to the kitchen. He evidently was being invited to hang out in his sister's bedroom. This was definitely new.
After he left Julie turned to Amy. "Your brother is sporting an impressive erection. Have you seen his cock naked?"
"No, not since we were little and took baths together. But sometimes it's obvious how big it can get."
