Lines We Cross

Chapter Two

“God!” she gasped as my thick nine-inch c**k sprang free and she dropped my boxers. Her eyes widened as she took me in her small hands plenty of room to spare. Jess had a similar look on her face, which I noticed but didn’t mention didn’t want to ruin the moment.

Lila leaned forward, giving me a soft, tentative kiss on the tip. She wasn’t doing much yet, but I moaned softly to encourage her. She giggled nervously, glancing up into my eyes as I stayed pressed to her lips.

I smiled back as reassuringly as I could, gently running my fingers through her soft, silky red hair and giving her breasts a firmer squeeze.

“You have to promise to tell me if I’m doing anything wrong,” she murmured quietly, her voice vibrating pleasantly against the underside of my head. “I’ve never done this before… You have to teach me what to do so I can be good for you.”

“You’re off to a strong start,” I assured her with a grin, making her giggle again. “Just do what feels natural… figure out what you like first, before worrying about what I might like. I promise I’ll speak up if I need to, but right now, more than anything, I just want to watch you explore and have fun.”

“Okay,” she smiled shyly, and I stroked my fingers through her hair again. Then she took a deep, steadying breath and took me into her mouth.

I moaned happily, and she giggled softly around me, making me moan again. She couldn’t take me very deep unsurprisingly, for her first time but when it comes to blowjobs, I’ve always valued enthusiasm over technique. Not that I had huge experience myself; I’d had a dozen or so girlfriends of varying seriousness. But I knew what I liked and didn’t, and despite her lack of practice, my sexy little step-sister was already proving herself to be well above average just from pure eagerness! It felt so good I wanted to tilt my head back and close my eyes but I wouldn’t, not when it meant missing a second of watching her work. Best of all were her eyes, a deep stunning green she’d inherited from the other side of the family, shining brightly up at me, clearly enjoying herself. I moaned appreciatively, letting her know wordlessly she was doing well, and she smiled happily around me at the praise.

As incredible as it was for me, and obviously for Lila as well, Jess seemed to be enjoying herself nearly as much; her hands had disappeared under the blanket, and although she bit her lip tightly to keep quiet, the blush of excitement on her cheeks was unmistakable. It didn’t take a genius to guess what she was doing to herself beneath the blanket that we couldn’t see.

But all too soon, Lila pulled away. My heart sank. Have I done something wrong? Had she changed her mind?

“Do you have a condom?” she asked shyly, her pale cheeks burning even deeper red. My brain was nearly short-circuited.

“Uh… yeah. In my room,” I managed to choke out. Oh my God! She was really going to let me do this! My gorgeous little step-sister was going to let me be with her!

“But… would you trust me to pull out instead? I’ll use one if you want, but I’d really rather feel you, not a condom, if you’ll let me.”

“I don’t know…” she nervously bit her lip. “I’m not on birth control Mom wouldn’t let me. You swear you’ll pull out? Not just at the last second… will you pull out early? Like, earlier than you think you need to, to be safe? I promise I’ll finish you off with my mouth if you do.”

“I promise,” I nodded seriously. I’d do anything she asked if it meant she’d let me inside that gorgeous little pink p***y I’d glimpsed earlier.

“Umm… okay, then,” she agreed, smiling bashfully. She lay back on the bed, pulling the blanket aside to cover Jess twice over, baring herself completely, biting her lip and slightly parting her thighs. She was even more incredible than the brief glimpse I’d had before. She’d trimmed her pubic hair fiery red like the rest of her into a cute little heart. The rest was perfectly smooth, either shaved or waxed, her outer lips a beautiful shade of pink, still glistening from when she and Jess had been playing. But despite how aroused she was, her tiny inner lips were barely more than a line, and her adorable little c**t peeked out shyly from under its hood.

I couldn’t stop myself; even after the offer of s*x I’d been dreaming about for so long, first I needed a taste. I crawled up onto the bed, laying myself between Lila’s legs. She gasped in surprise, her soft, slender thighs trembling against the sides of my head, her fingers burying themselves in my hair and pulling me tightly to her. She was utterly delicious, fresh, subtle, and unmistakably her. That familiar taste all women share was there, but hers was softer, more inviting. I dove in, tongue pressing deep into her, gently coaxing her to open up, preparing her as best I could.

“Come here,” Lila purred, and for a second I thought she meant me. But as I looked up, I realized she was talking to Jess. My step-sister was nervously biting her lip, hesitating until Lila reached over, ran her fingers gently through her hair, and drew her close. Jess moved almost involuntarily, emerging from beneath the blanket. Her large, soft chest pressed against Lila’s side as they began to kiss, tender at first, then quickly more heated. They shifted, hands finding each other’s bodies, caressing and groping with growing passion.

I moaned into Lila’s folds, my c**k throbbing against the bed as I watched the two girls, my step-sister and her best friend kissing feverishly, their tongues exploring, their hands entangled. My hands held Lila’s hips steady as she rocked herself against my face. Jess moved in closer, trying to grind against Lila’s thigh, but ended up brushing against the back of my hand instead. She flinched, pulling away in embarrassment, but I looked up at her with a reassuring smile and a slight nod.

Blushing, she inched forward again and this time, when I began to lightly stroke her between the legs, she didn’t stop me. She moaned softly and lifted one leg, welcoming my touch.

I wasn’t in any rush. I was enjoying this too much to hurry. And from the look on Lila’s face, she felt exactly the same. But her body had other plans. All of a sudden she gasped, her eyes flying wide, thighs clamping against my ears. Her moans grew sharper, louder, her legs trembling wildly. Clearly, she hadn’t expected to c*m so soon or so hard. She writhed helplessly under my tongue, hands clenching the sheets, until finally she shoved at my head, too sensitive to handle anymore. I chuckled softly, pulling back and kissing the inside of her thigh while she caught her breath.

“That looked like a good one,” Jess giggled, leaning in again and softly kissing her cheek.

“Uh hunh!” Lila agreed wholeheartedly, her eyes partially hooded, sexy, and very, very satisfied. “I’m not even sure exactly what he was doing down there… And don’t take this wrong, or anything. You’re good, too! But next time I let him do that to me, you need to get down there and watch, so you can take notes!”

“Will do!” Jess laughed, and as she looked down at me again she blushed. Neither of us had acknowledged it out loud, yet, but I could hardly wait for the chance to show off my technique for her, as well and in person, between her thighs, not just letting her watch! For the moment, however, I had other priorities; as Lila bit her lip, beckoning me up the bed with her finger, I was only too happy to oblige.
