“Sis…”
“Shhh… Bobbie, less talking and more poking. Let’s just enjoy this now, okay?” She pulled him down for a long, warm kiss as they continued bouncing together.
She broke the kiss to whisper, “So deep.” Then she sighed and closed her eyes. One of her hands skidded down her flat belly to play at her clit. She unwrapped her legs from Bobbie’s waist and spread them. She pointed her toes and the muscles in her young legs flexed smoothly as she held them open wide.
“Harder, Bobbie,” she grinned, “Do me like you’ve always wanted. Go ahead honey, I can take it.”
She didn’t have to ask twice. Her brother bore down on her and Heather squealed happily as his pace doubled. I watched her adorable little teen face squish up in concentration.
“I feel like I could go again,” she whispered and turned to look at Sam and me, “but I can’t quite…”
Sam never let Heather finish. Whether it was because her silly knack kicked in or because she was another woman and just naturally knew what Heather needed, it didn’t matter. Sam slid onto the bed next to the bouncing siblings. She sucked one of Heather’s rocking breasts into her mouth, working the smooth round orb with her lips and tongue.
Heather’s jaw fell open and she gasped a breathy, “Ooooh, yeah.” She twisted her fingers into Samantha’s long dark hair and pulled her tighter into her chest.
But Sam wanted to play with more than Heather’s tits.
“Honey, what’s your first memory of Bobbie?” she asked sweetly, looking up from Heather’s chest.
“Huh?” Heather panted.
“Your first memory. Think back.”
“Now?” Heather smirked as her brother pummeled her body relentlessly with his long shaft, “Kinda busy here, Sam.”
“C’mon, just tell me.”
Heather stared at the ceiling for a long moment as her brother fucked her with all the energy of a teenage boy living his wildest sexual fantasy. Then she laughed.
“Birthday cake. We were little. It was my fourth birthday and Mom made me a Garfield birthday cake. Bobbie and I both wanted the same piece of cake. It had Odie on it.”
“What happened?” Sam asked around a mouthful of Heather’s rocking, round boob.
“I… I gave it to him. I love my little brother.” Heather looked at Bobbie and smiled, “I wanted you to be happy.”
“Mmmhmmm, ever kiss Bobbie before today?”
“Sure,” Heather’s answer came as a grunted. Bobbie was still fucking her vigorously.
“But ever kissed him and felt a weird little urge to linger?”
“Errr….”
“Don’t be shy, now is no time for secrets,” Sam chided. “For example, I have to admit that I planted a giant sloppy, smooch on my big brother the first time I got drunk. I even slipped him some tongue. How embarrassing! He still teases me about it. What about you? You never lingered?”
“Yeah.”
“When was that?”
“I’d just started high school. I’d come home from playing spin the bottle for the first time. I’d been kissing boys all night. When I got home, I pecked Bobbie on the lips and… I dunno… I drew it out for an extra second. With my lips pressed against his. No tongue or anything. It was… it was nice.” Heather looked up at her brother, “I wanted to know what you kissed like.”
