Frank offers his services

"You two don't look much alike for sisters," Frank commented, pouring their glasses full.

"We're step-sisters," Susan said. "Mom married Maya's dad about ten years ago."

Frank nodded thoughtfully, smiling carefully at the girls as they ate and drank. "You seemed to think I was amusing at the mall this morning."

The girls blushed and looked at each other, then giggled with embarrassment.

"Ummm...no...we were just talking about something funny..." Maya said.

"Really? Because I was sure you were laughing at me. Maybe because you noticed the bag from the sex shop?"

The girls blushed deeper, shaking their heads in denial even as they giggled.

"No...really...it wasn't that..." Susan stammered.

"Are you sure? I can show you what I bought if you like."

"Ohmygod!" Maya blurted, her face flushed. "You brought it here? What is it? I wanna see!"

"Maya! Ohmygod! Don't be so weird!" Susan gasped, although he eyes were wide and excited.

"Nothing weird about it," Frank grinned, pulling an egg shaped vibrator out of his pocket and showing them. "I bought this for a special friend."

"Ohmygod!" Maya exclaimed, her eyes glittering. Susan looked at the vibe with fascination, her hand over her mouth.

"It's so she can have fun when I'm not around to...service her," Frank smiled reaching out and stroking Maya's arm. "You know how it can be when you don't get enough...servicing, don't you girls?"

"Ohmygod!" Maya gasped, her nipples swelling and bulging under her top. Susan was biting her lip and looking from the vibe to Frank and back again, her excitement showing in her face.

"Have you to been getting enough servicing?"

"Not enough..." Maya moaned softly.

"Not nearly enough..." Susan whimpered anxiously.

"Maybe I can take care of that for you," Frank growled.

"Ohmygod!...yes...yes please..." Maya whispered.

"Yes...both of us...please..." Susan purred, pressing against Frank's arm.

"There's that folding couch...in the family room...I fucked Jason on it...." Maya whined, tugging at Franks arm, her face full of need.

"You slut!" Susan giggled. "It's perfect....hurry...."

Frank let them lead him into the room and grinned as he saw the couch.

"You sluts have too many clothes on," he growled, eyeing them hungrily.

"Ohmygod! Yes...yes Mr. Castillo!" Susan babbled excitedly, starting to strip.

Maya watched her sister for a moment then peeled her own clothes off, discarding them on the floor. In a moment the two girls were half naked, sitting beside each other, giggling as they toyed with themselves.

"Yeah, now you're ready for servicing," Frank chuckled, stripping his own clothes off and advancing on the girls, his cock rampant and ready for action.
