The Sister, Part 34
Part 34
From our very first interaction to the present, I had yet to perceive Natalie as ‘slutty.’ Even when she was throwing herself at me, she walked that perfect line of cute and hot so well, and managed to be direct while not being overt or over the top with her seduction tricks. Here she was, standing fully nude in front of me, and it was really tough to think of anything else but leaping at the opportunity.
The one thing that kept me in reality was the fact that I was still dressed. I could still remove myself from the situation and avoid fucking the younger girl again; she would probably take a shower in here regardless, but that was obviously better than cheating on my girlfriend. Of course, that didn’t stop me from drinking in Natalie’s body with my eyes, when I should have been averting my gaze.
Natalie’s ‘logic’ was also starting to get to me. Doing the right thing didn’t mean nearly as much now that we had already done so much behind Jessica’s back. If I had to carry the secret of what Natalie and I did earlier to the grave anyway, maybe it was better to lean into all of this and get the most out of it. And, though it was a ridiculous concept to justify the thoughts racing through my mind, maybe getting on board with Natalie’s games and not resisting in the slightest would decrease her interest in me. She clearly enjoyed the chase, unless it was purely the allure of the taboo; my assumption was that it was both for her.
Before I could think through any of the ideas sparked by Natalie’s nudity, she walked up to me and moved things along when I didn’t come up with a response to her recent question. “I think you should stay,” she said. With that, she lowered herself to her knees and reached forward to undo the button on my shorts. She took her sweet time, too. Gripping the waistband, pausing to give me a chance to reject her, then deftly popping the button free when I ended up both frozen and speechless.
What was I supposed to say? A hot eighteen year old was more or less offering to go down on me. Again. I knew it was wrong, but it was getting more difficult to say ‘no’ to her with every passing minute. I was no longer just thinking with my brain, either. The sight of Natalie on her knees, casually undressing me with her lips pursed in that sultry smile, was enough to get me to stir below the waist.
After taking care of the button, she proceeded to slowly pull down my zipper, keeping her gaze trained on me all the while. Once the shorts were loose around my waist, she pulled them down far enough down my thighs that gravity would do the rest of the work for her. Then, just as nonchalantly as she had approached everything else, Natalie rested her hand on my crotch.
All it took was a single touch over my boxers for my faint arousal to turn into something a lot more telling. “You want to stay.” She shifted down far enough to slip her hand underneath one of the leg holes, then worked her way back up my bare thigh until she had a gentle grip on my partial hardness.
It wasn’t lost on me that she had so quickly gone from ‘I think’ to ‘You want.’ And I did, which I affirmed with a reluctant nod.
“Say it, babe.” After tracing up and down with her fingertips enough to work me closer towards a full erection, she teased away with her hand, retreating from my underwear long enough to get a grip on the waistband instead. Rather than further stripping me, Natalie merely fiddled with the fabric.
Knowing she wouldn’t continue until I did what she wanted, I muttered, “I want to stay.” Obviously. My window to shut this down had very much come and gone.
“Mm hmm,” she hummed. Rewarding me right away, she began pulling down my underwear. Pausing for suspense, letting my cock provide a moment of natural resistance against her little tugs, she then pulled the garment enough that I popped free of the fabric.
Right away, she leaned forward and took me into her mouth.
Fuck. With a single bob of her head, whatever lingering reservations I had about all of this vanished. Between the warmth and wetness that welcomed me–complete with her tongue playing against my manhood–as well as the literally steamy setting as Natalie went down on me while the hot water continued running in the background, I was officially under her spell.
To my dismay, she pulled back and detached herself within seconds. “Take off your shirt,” she quietly demanded.
I didn’t need to be told twice. Grabbing the hem of my tank top, I pulled it over my head and haphazardly tossed it towards the corner of the bathroom.
“Good boy.” Once again rewarding me in a way that made it obvious that she was doing so because I had done what she wanted, she wrapped her lips around me down there a second time. She pulled back just like before, this time standing up while saying, “But you already fucked that hole, babe.”
Now that we were both fully undressed and I was sufficiently turned on, all it took was a simple statement like that to make me throb in need. I knew exactly what she meant, and what she was leading to.
Natalie pressed her body into mine and gently rubbed against me. It was more than enough to make me put my hands on her on instinct, and keep her close. Not too close, apparently, as she shifted her hips back so I could no longer grind her beyond the fleeting moment I had been given. “You already fucked that hole, too,” she smirked, “Let’s go, babe. You can take me from behind in the shower.”
