Chapter 10
Dipper stood up and nervously began to undo the button on his jeans. This was it, the moment he had been waiting for since he first realized he had feelings for Pacifica. His mind was racing, his fingers twitching. He couldn't believe this was happening, and with his sister by his side no less! He didn't even know what to think anymore.
Mabel, on the other hand, couldn't have been more eager to get started, practically tearing off her pants before making quick work of her own bra and panties.
"Hey Dipper, catch!" Mabel yelled before tossing her brightly-colored bra into her brother's face. Dipper, caught off-guard, pulled the undergarment away only to have his jaw drop at the sight of Mabel's naked body.
Her breasts were a bit fuller than Pacifica's, her body slightly curvier, and every inch of her form looked as smooth as silk. As ashamed as Dipper was to admit it, the sight of his sister naked on the bed beside a half-naked Pacifica was incredibly arousing.
"Well, what are you waiting for?" Mabel asked. "Let's see what you got."
Dipper nervously unzipped his pants and pulled off his jeans, the outline of his erection clearly visible through his boxer shorts. With one final breath, he pulled his boxers down, exposing his member to the ladies, whose eyes bulged at the sight of Dipper's extremely hard and throbbing manhood.
"Whooo!" Mabel whistled. "That ain't no little Dipper! What do you think, Pacifica?"
Pacifica only sat there, mouth agape at the sight before her.
"It's . . . ummmm . . . impressive." Pacifica said with a blush.
"Yes . . . Yes it is." Mabel replied as the two girls sat impishly and stared, admiring Dipper's impressive package, causing the poor young man to blush with embarrassment.
"Ummmm . . ."
Finally, after a few awkward moments of ogling.
"Okay, your turn!" Mabel shouted, and quickly began to paw at the Pacifica's capri pants.
"Wa-wait what?" Pacifica gasped.
"Dipper, grab her arms!"
Quickly, the Pines twins surrounded the heiress and pulled her pants off, leaving her in nothing but a pair of lacy pink panties.
"Nice." Mabel smirked. "Now let's just get rid of-"
"Wait!" Dipper yelled.
Mabel froze, looking up at her brother, who was busy staring intently at Pacifica's panties.
"What's wrong?" Mabel asked inquisitively.
"I just . . . " Dipper started, lifting his hand to Pacifica's lap. "I want to take things slow, Mabel."
With that, Dipper's hand made contact with the young blonde's loins, sending the heiress into a daze of lust and ecstasy.
"Ohhhhhh yessssss!" Pacifica hissed as Dipper began to caress the young woman over her underwear.
"Oh Dipper, that feels . . . soooooo good!" she moaned.
Mabel smirked and laid down besides the quivering young lady. "Hmmmm, good idea, bro."
Mabel lifted her hand to Pacifica's panties, and, working in tandem, the Pines twins began gently massaging her to a blissful climax. Pacifica tossed and turned on the bed as Dipper and Mabel began fondling her in places no one but herself had ever touched. Every fiber of her body tingled with excitement as a tidal wave of pleasure began to flood her very core. Pacifica's body tensed with anticipation as her twin lovers manipulated her in ways she could never imagine.
"I think she's ready to pop, bro." Mabel smirked.
The twins' hands descended past the young lady's undergarment, making bare contact with her sex. Pacifica spiraled over the edge, and in a tantric spasm of pure euphoria, she threw her head back in a mind blowing orgasm.
"OH DEAR GOD!" Pacifica exclaimed, her legs shaking, her eyes rolling back in their sockets.
"It's so good! I Love It! I LOVE YOU BOTH!"
. . .
Finally, Pacifica calmed down, her body relaxing back onto bed as the Pines twins hovered over her, caressing her quivering body.
"Thank you." She whispered.
"Our pleasure." They responded.
The three of them laid there for a while, with Mabel and Dipper's hands stroking up and down Pacifica taut body, basking in the glow of her radiance.
Until . . .
"Okay, our turn!" Mabel squealed, pulling off Pacifica's panties before jumping up and straddling her waist.
"Mabel, what are you doing?" Dipper shouted.
"What do you think, silly?" Mabel responded, lifting and pulling apart Pacifica's legs, exposing the heiress' sex to the erect young man. "I'm getting her ready for you, Dipper."
"You take this side, and I'll get her mouth. What do you say?"
