“Heather? Honey?” I asked softly.
Heather’s eyes opened. “Oh, right. Sorry. Your turn, bro’.” She let his arm go. Bobbie was still looking at his sister briefly as he turned towards Samantha.
I scooted aside and he dipped his face between her legs to began licking and teasing her folds carefully. He was a little slow and awkward at first. Sam reached down to run her fingers through his hair. She used that grip to encourage him at some points, discourage him at others.
Heather and I watched them together. Right up until Heather got impatient just watching. Before I could stop her, she moved in, nosing her brother out of the way.
“How about trying this… I’ve been meaning to try this…” She lowered her mouth to Sam’s small wet sex and used her tongue to trace a quick series of X’s centered on Samantha’s button.
Sam’s hips humped quickly up into Heather’s skilled mouth, “Oh wow,” she mewled. Clearly, Sam liked it.
Bobbie stiffened in shock. “Uh, sis? You just?”
Heather winced as she pulled her face from Samantha’s rolling crotch with an embarrassed look. “Oh! Yeah, Sam and I… we…”
Bobbie didn’t need her to finish. It was pretty obvious. “Wow. I had no idea.”
“I wasn’t exactly advertising it to my kid brother. Does it freak you out?”
“No, I guess not. Actually, I think it’s kinda cool.”
Heather shrugged and smiled at her brother. “Good. Now we have something else in common – we both like pussy.” Heather giggled. “Just don’t tell Mom okay?”
“So you’re okay with me telling Dad?” Bobbie joked.
“Har har. No, don’t tell him either, dummy.” Heather poked her brother.
The three of us at the bottom of the bed laughed and a weird sort of tension broke.
Sam’s voice came down from above. It was a whine full of need, she still hadn’t cum. “Would one of the three of you – I don’t fucking care who – please finish what you started?”
Heather quickly nudged Bobbie’s head forward, back to his task. “That’s better,” Sam moaned with relief when he went back to eating her, “much better.”
Soon, Bobbie’s gentle laps and teases on Samantha’s tender little folds were already getting smoother, more confident. Samantha rewarded him by starting a low, long moan and humping gently into his face. “Just like that. Yeah, you’re a good little pussylicker. The girls at your high school are going to be lining up when word gets out.”
Bobbie’s eyes flashed proudly at Sam’s compliment.
Heather agreed, “She’s right, bro’. Teenage girls can get all the fingering and fucking they want. Good oral is hard to find.”
By now, Sam was getting very worked up. She pumped her hips more urgently and pulled Bobbie into her crotch. She rolled her groin in circles, using his face. “You’re going to make me come Bobbie. I’m going to come because of you. The first girl you’ve ever eaten to an orgasm. Are you ready? Ready for me to come on your face, honey?”
Bobbie only response was to work at her drooling sex more vigorously. Smart boy.
Sam humped up into him, moaning and grunting, and shuddering as she finally came after dangling on the brink of an orgasm for over half an hour. It was a beautiful thing to watch. The muscles in her gorgeous little thighs rippled as she came. Her round little breasts rolled up and down on her chest. Her mouth hung open and her head rolled back and forth haphazardly.
