Rachel like I've never seen her before

As my eyes adjusted to the dim lighting in in Rachel's room, my mouth fell open in shock at the sight I witnessed on the bed. My sister was laying on her back, her legs spread wide, the skirt of her school uniform hiked up over her hips as two fingers feverishly explored her sex. Her blouse was pulled open, exposing her breasts, her other hand mauling her left breast as she tossed her head on her pillow. Her cheeks were flushed, her hair plastered to her forehead as she furiously masturbated.

"Oh," Ria gasped again, leaning back in surprise, pressing against me as I blocked her exit from Rachel's room. "Oh," the petite Pakistani repeats as she feels me close to her, her back pressing hard against my chest, my growing erection nestling into the soft flesh of her ass as we both stand there watching my sister feverishly frig herself.

"She looks good like that, doesn't she?" I whisper into Ria's ear, knowing that the Axe effect was in full effect as I feel her slender body tremble against me, her breathing coming in short deep gasps as I slide my hands around her narrow waist. I grip her gently, pulling her back against me, rubbing the hard bulge of my erection against her soft rear, hearing her short sharp gasp as I grind against her.

"I... we shouldn't.... yes," Ria almost sighs, her hands reaching up to lightly caress her now heaving breasts as she watches her best friend writhe in pleasure on the bed.

"Would you like to feel as good as she does, Ria?" I ask, my hands sliding down to her slim hips, fingers kneading her soft flesh through her tight jeans.

"I...," Ria gasps, almost nodding her head before her strict upbringing asserts itself. "I can't, Mike," she almost sobs, "but..."

"But?" I ask curiously as my attractive East Indian neighbor turns to face me in the darkened doorway.

"But I can make you feel good," she assures me, her brown eyes large as she looks up at me, holding my gaze as she slowly kneels in front of me.

"I have to save myself for marriage," Ria assures me, her fingers fumbling at my pants, pulling them down to reveal my throbbing erection. "But that doesn't mean I can't give you pleasure," she says softly, almost as if convincing herself more than telling me. Her hand is shaking as she takes my cock in her grip, her touch tentative and shy as she strokes me, the sounds of my sister's pleasure filling the bedroom as she starts to gain confidence. Soon she is stroking me confidently, her hand caressing my hard cock as she looks up at me, seeking assurance as she performs this first sexual act. "Would... would you like me to use my... mouth?" She asks softly, her pink tongue darting out to lick her dark lips as if testing the idea in her mind.

"Please," I murmur, my hand falling down to the back of her head, fingers curling into the dark tresses as she leans forward, her breath hot on the tip of my cock as her tongue stretches out, licking over the swollen tip. I let her lick me a few times, getting accustomed to the taste before I gently guided her head closer to my crotch, sighing as she opened her mouth, letting my cock slide deep into her mouth. She was hesitant and inexperienced but the thought of getting a blowjob from Ria coupled with the erotic sight and sounds of my sister fingering herself on the bed pushed me to my limit almost instantly. I felt the pressure building deep in my stomach as I tried to decide where I wanted to finish. In her mouth or on her pretty face?
