Alex entered their room with a pile of clean clothes in her arms. She dumped them on her bed and then started folding them. John watched what he considered to be a perfect ass. Perhaps even the perfect ass. Alex preferred to wear form-fitting leggings that showed off her firm, well-defined butt. Today, she shrouded her glutes beneath a pair of loose-fitting sports shorts. They may not have hugged her backside, but they allowed her ass cheeks to wiggle and flex as she moved. John's cock showed its appreciation for her clothing choice.
A loose crop top shirt kept her braless topside decent. Or rather, decent enough. Bending over, the shirt would billow open, allowing John various views of her breasts with a subtle nipple hint. An enjoyable vista that he did not usually see. His cock thoroughly agreed with John's assessment.
Alex announced without turning, "The big family reunion is this weekend."
"Ugh," John rolled his eyes. "I wish we didn't have to go. Aunt Edna always tries to cop a feel of my ass."
"What if I told you we don't have to go this year."
"No way. How'd that happen?
Alex shifted to the other side of the bed to face John while still folding the clothes. "Dad wants to drive this year. To save money, we'll use Mom's car. He said it would be a tight squeeze with five people."
John grinned. "You could sit on my lap."
Her eyes drifted over to the bulge in his pants. "As tempting as that would be. It won't be necessary. I suggested that you and I could stay home."
"And he went for it?"
"He said that would work out well. Apparently, the sleeping arrangements had you and me sharing a bed. That would be seen as inappropriate, even as twins. They are worried that certain things might go bump in the night.
John laughed, "We wouldn't want that, now, would we?"
"Dad laid down some ground rules for staying home alone: no friends over, no parties, and no drinking our way through the liquor cabinet."
John smiled, "But he didn't say that we can't drink."
Alex leaned across the bed as she reached for the twin to the sock she held. Her torn shirt collar hung down, putting her tits on display. "They're leaving right after work on Friday. They will take Grandma to visit Grandpa's grave on their way home and won't return until Monday.
John locked his eyes on Alex's chest as her nipples pressed against the fabric of her shirt. "So, we'll have the house all to ourselves for the whole weekend?"
"Kids, dinner in 15 minutes," their mother called from the base of the stairs.
"Okay," Alex acknowledged. She turned back to John. "I might see if Jenn wants to come over on Saturday. Depending on how Friday goes."
"What's happening Friday?"
"You'll have to wait and see."
She walked around her bed and then over to John. "But first, you are sporting something totally inappropriate for the dinner table."
She hooked her fingers under the tops of his shorts, pulling them down in a single motion. Her eyes smiled at his hardened manhood. She wrapped her hand around his shaft. "Let's take care of that right now."

John and Alex stood by the open front door. They waved to the parents and grandmother as they drove away. The twins watched until the car was out of sight, then closed the front door. The lock hadn't even fully latched before John's hands were under Alex's shirt, pawing at her tits.
John tweaked a nipple. "What do you want to do first?"
"We watch a movie."
"What?" John pulled up short. "Why?"
"How often have we left on vacation and Dad not turned back thinking he forgot something?"
John shrugged, then rolled a nipple between his fingers. "Good point."
Alex pulled her shirt down. "You find a movie, and I'll get a blanket." She said and headed to the linen closet.
"A little warm for that, isn't it?"
John was already on the couch when she returned. She spread the light blanket over the two of them. Snuggled under John's right arm, Alex placed a hand on his chest.
John pulled her in tighter, enjoying her closeness.
As the movie started, her hand drew lazy circles on his chest. Gradually, the circles drifted over to his left nipple. Her fingers encircled it in ever-shrinking swirls until they came into contact. With thumb and forefinger, she gently tugged on his nipple, feeling it harden to her touch.
Preoccupied with what she was doing to his chest, he didn't notice her other hand slowly move to his crotch. He let out a sigh when Alex massaged his cock through his pants. When he was good and hard, she released the button, pulled down the zipper and reached inside his boxers to include his balls in on the action.
"Fuck, Alex, that feels so..."
The front door opened. John scrambled, trying to push Alex's hand away as their father walked through the door.
"Sorry, kids, we were at the edge of town when I remembered I didn't pack Mom's toiletry bag."
Their father walked over to the couch. He wasn't concerned about seeing Alex under a blanket leaning against John. The twins had been doing that their whole lives. "What are you two watching?"
Alex kept stroking, her movement concealed by the blanket. "Not really sure. We are talking more than watching." She paused. "I know you said no friends over. Can Jenn come over tomorrow? We have some biology to study."
Dad paused to consider. "Okay, but just Jenn. What are you studying?
John gasped when Alex ran her fingernails along the underside of his shaft. "Anatomy."
"You okay there, son?"
"Yeah, Dad, I thought that I had to sneeze."
Alex pulled a frowning face. "Aw, poor baby, are you starting on a cold?" She slowly stroked his cock. "Don't worry, Dad. I'll take good care of him while you and Mom are gone."
"That's my girl," he said as he headed toward their parent's bedroom.
John put a hand to his crotch. "Stop," he whispered.
"Make me." Her increased stroking was rewarded with a quiet moan from John.
"Found it." Their father's head popped into the room. "It was on the bed."
Outside, the car horn honked. "I gotta go. Don't let anything get out of hand."
Alex chuckled and then increased her grip. "I fully intended to keep everything in hand. Love you, Dad."
By the time the door latched, John had already flung off the blanket. Alex continued her stroking. Hooking his thumbs onto the top of his pants and underwear, he pulled them down, freeing his cock. Now unencumbered, Alex stroked hard and faster.
John laid back, his eyes closed. "Fuck, that feels so good. Did you need to do this in front of Dad?"
She swirled precum over the head of his cock. "All part of the plan, Bro."
Sliding a hand down her pants, John ran a finger over her slit. Alex shuddered at the feeling. John dipped a finger inside of her. "And was this part of the plan?"
Alex closed her eyes and sighed. She slowed her strokes as she concentrated on her own pleasure.
"You are so wet," John whispered.
"You, dear brother, are so very hard."
John's fingers teased forth her clit. Gathering up some of her wetness, he slathered it over her clit as he rubbed it.
Her eyes rolled back as a tingle ran through her body. She put a hand on him, halting his movement. "As much as this feels so good, we must stop."
John plunged a finger deeper inside of her. "Why?"
"We can't do this here."
