The next day, Justin and Emily worked out the details of how to sneak Jill into the house to watch their parents have sex though the peephole in Justin’s room. They toyed with the idea of crawling in through the window (as the bedrooms are on the ground floor) but the windows were high enough to make that awkward. It might look suspicious to any neighbor that happens to see.
Instead, Emily would meet Jill out in the back yard and wait for Justin to text them. They could quietly enter the back patio door and come down the hall to Justin’s room, hopefully without missing too much.
“Jill’s really excited about this,” Emily reported after filling her in on the plan.
“Is Jill still a virgin?” Justin asks.
“I think so,” Emily says. “She’s insatiably curious and we talk about it all the time, but she’s way too timid to actually do anything.”
“I still think it would be easier if she just watched us,” Justin suggests as he slides his hands around Emily’s body to cup her tits.
“No way!” Emily cries as she wriggles free of his grasp. “I would die of embarrassment if Jill found out we were doing it.” She points an accusatory finger at Justin, “And don’t you say anything to her either!”
“Okay, okay,” Justin reassures her. “It will be our little secret. What if Jill gets as hot as you did watching? Is it okay if I help her out too?”
Emily pauses thoughtfully. “Will you always be there for me?” she asks.
“Of course,” Justin says, wrapping her in a comforting hug. “You’ll always be my special sister.”
Emily snuggles into his embrace. “Thanks. I suppose I can share you with Jill if she wants. She shouldn’t miss out on all of the fun.” She looks up at him with an adoring smile on her face. “Thanks for asking me first.”
“Anything to keep you happy,” Justin replied. As they hugged, Justin moved his hands down to her rear. “Speaking of which, can I make you happy right now?”
“Who are we making happy now?” Emily replied playfully. “Why don’t you save it for tonight?” She gave him a kiss before heading out of the room.
They had to wait longer than tonight – no opportunities arose for three days. Even tonight looked like it might be another disappointment as Justin kept an eye on what was happening in his parents’ room. However, just as it looked like his parents were going to go to sleep, his Dad leaned over to Mom to give her a good night kiss. As the kiss lingered, Justin quickly sent the text to summon Emily and Jill inside.
A few seconds later, the pair of girls quickly, but quietly, zipped into his room. Both of them were wearing T-shirts over skirts. Emily whispered a “thank you” to Justin as they both knelt on the floor and started peering in the holes to the parent’s room.
Justin lay back on his bed and picked up a book to read. His focus was more on the girls than on his novel. Jill’s long blonde hair contrasted with his sister’s shorter brown curls and emphasized her thin frame. Justin was pretty sure that Jill stood a little taller and she walked with a light spring in her step.
She also seemed accessorized to death with a ribbon hair clip, large hoop earrings and necklaces, bracelets, and rings her body. ‘So complicated,’ Justin thought as he watched the two girls whisper furtively to each other.
A few times, he could hear gasps of surprise coming from Jill before an exchange of whispers followed. He hoped they weren’t being too noisy. Twice Jill looked back at Justin. He returned her second glance with a friendly smile. Jill then whispered, “Can you leave for a bit?”
“Why?” he asked.
“Please?” she said with an urgent tone to her voice.
“If you’re going to play with yourself, go ahead. I’ll know that’s what you’re doing when I leave anyway.”
“It’s okay, Jill,” Emily said. “He can’t see anything anyway.” One her hands moved towards Jill. Emily was right – I really couldn’t see anything, but I imaged that her hand was either moving under Jill’s skirt, or guiding Jill’s hand there.
“What… aah…” Jill sighed as unseen fingers stroked her privates. It wasn’t long before Jill forgot all about me and was aware only of the action in the other room and the action between her legs.
A few silent minutes passed with only the heavy sound of breathing in the room when the girls moved away from the wall and lay out on the floor. As Justin got up from the bed and grabbed the pictures to recover the peepholes. He could see that both of their skirts were quite a bit higher than they would normally be.
He sat down on the edge of the bed and asked, “How was the show, girls.”
“Every bit as good as last time,” Emily replied as they sat up. “I think Jill enjoyed it quite a bit too.”
“It was a bit dark in their room,” Jill said. “I wish I could have seen more.”
“I’m right here,” Justin offered, gesturing towards his body.
A pillow flew through the air striking him flat in the face. “Nice try,” Jill replied. She quickly realized whose room it was though. “But thanks for letting us watch.”
“We’ll have to do it again,” Emily replies. Jill nodded in agreement.
As quietly as they entered the bedroom, the two girls snuck back out and disappeared down the hallway. A minute later, Emily quickly returned alone. She moved quickly to Justin and wrapped her arms around him.
“Watching them made me so hot!” Emily said as she pushed herself into Jim’s lap. “I need you now!”
Justin was more than willing to oblige. His hands moved to her rear, scooping her up in his grasp. He gathered up the material of her skirt to reach underneath and discovered that she was naked under her skirt. “You really couldn’t wait, could you?”
“Nope,” she gasped as she fumbled with the zipper on his pants. It didn’t take long before she had his cock free. “Didn’t want anything in the way.”
Emily lifted up and impaled herself on his cock. “Yes… that’s just what I need…” Quickly, she started bouncing up and down on his cock.
Justin pulled up her shirt and to find her tits unrestrained. He leaned forward to suck the nipple into his mouth. As his tongue played over the tip, Emily’s breath got heavier and more insistent.
The two lovers only heard the noise because they were trying to be quiet. A tapping on the window echoed through the room. As they both turned towards the window, they could see Jill standing outside looking in with a shocked expression on her face.
There was a moment of shocked silence when everyone was frozen, staring at each other, before Jill bolted away from the window disappearing into the night. Emily collapsed into Justin’s arms and started whimpering.
“Quickly, Emily. Chase after her. You can explain,” Justin quickly tried to reassure her. “She’ll understand. I promise. She’s just surprised right now.”
“Really?” Emily replied in disbelief.
“Yes. If she’s a real friend, she’ll still like you. Now hurry.”
Emily pulled her skirt and shirt down. There was a moment’s hesitation while she regained her composure before she dashed out of the room.
