The Sister, Part 22
Part 22
By the time Jessica had emerged from the water and turned her attention back to the boat while treading water, Natalie and I were both standing up in order to make it clear to my girlfriend that her little sister was doing nothing but applying sunscreen to my back.
It had actually been my idea, rather than hers. I had jumped up from the white leather when it crossed my mind that the edge of the boat would partially obscure us due to Jessica seeing us from a lower angle. If this had just been sunscreen, I wouldn’t have thought twice about such things. After everything Natalie and I had done together, however, including the latest few things she had initiated but I certainly hadn’t denied, I couldn’t help but act in ways that would keep Jessica from being suspicious.
“I should really thank her,” Natalie said. Though she was out of my sight, I could tell that she was slightly leaning towards my right ear as her hands continued to roam my back. Not whispering, but speaking in a lowered tone that Jess definitely wouldn’t hear from down in the water. “For bringing me such a fun toy to play with, I mean. I was worried about being bored up here, you know?”
I didn’t say a word. Partially because it felt so wrong to be looking at my girlfriend while her sister so boldly flirted with me, and partially because I had no idea what to say to something like that. No one had ever spoken to me in such a playfully objectifying way. Just like ‘good boy,’ which was also a first for me, Natalie’s style of teasing was surprisingly effective.
“Soooo, when are we going to have some more fun together?” she asked. Her hands finished working the lotion into my shoulders and she shifted inwards to massage my neck. “After Jess goes to bed? Or is it more hot when we fool around while she’s still awake?”
This time, I did reply. Giving a small shake of my head, I murmured. “Natalie. We can’t.”
“Mm hmm. Except, umm . . . we did, remember? So I’m pretty sure we can.”
“You know what I mean.”
“Do I? But, I’m so young and naive! Why don’t you explain it to me, babe?”
We both knew damn well that she was far from naive. And we both knew exactly why all of this wasn’t okay. Except there was no good way to assert the obvious when I was constantly worried about Jessica catching a snippet of the conversation. Luckily for me, my girlfriend was as much of a mermaid as she had told me on the way to her family’s vacation house. She loved the water, and watching her swim confirmed she was far more interested in enjoying the lake than she was in impatiently waiting for us to join her.
“Don’t play dumb,” I said, “What we did? It can’t happen again.”
Natalie let out a dramatic sigh. “You said you would fuck all my holes. You promised!” Pausing with both her hands and her voice for a moment, she then went on, “Fine. Be like that. But, I’m curious–if you had to choose, which would it be? Fuck me while she’s awake in the other room? Or while she’s sleeping?”
It was impossible to keep the mental images away. Taking her from behind. Making out with her in a dark hallway while Jessica was doing dishes around the corner. Going at it in Natalie’s room while my girlfriend was sleeping soundly on the other side of the wall. “Neither,” I managed to reply. It also wasn’t lost on me that she was twisting what had been her overt teasing from earlier into a ‘promise’ that I definitely hadn’t made.
“Both. Got it,” she softly giggled. Her hands glided down to my lower back to rub sunscreen on the one area she hadn’t hit yet. “You know, a lot of boys would kill for this kind of attention from me.” Her fingertips slipped beneath the waistband of my swim shorts, tracing just a little bit lower than necessary as she circled left and right with the lotion. “And you said it yourself. I’m better. You want me more. So what’s the problem?”
Yeah, but she compelled me to say both of those things. It didn’t matter if there was a hint of truth to them. Not that it was a fair comparison, considering that I had known Jessica for more than half a year and Natalie for less than half a day.
“I’m dating your sister,” I said. Saying it out loud felt so ridiculous. It’s not like it was new information for her.
“Uh huh.” Her hand dipped lower and gave a light squeeze to my bare ass. “And you can fuck her whenever you want. You only have me for a few days.” Removing her hand as if nothing had ever happened, she sensually ran her palms up my back. “Think about it, babe. We’ll chat soon, ‘kay?” Natalie concluded her physical contact by tracing an invisible heart on my skin with mirrored index fingers. Then she circled around and sauntered over to the edge of the boat. “Coming in!” she called to Jessica.
The way Natalie slightly bent forward drew attention to her backside. If that wasn’t enough, she glanced over her shoulder and gave me a small air kiss with just her lips. With that, she wasted no time in jumping over the side and into the water.
This weekend was turning into so much more than I had bargained for. It would have been one thing if Natalie’s general presence had been cock blocking me from what was supposed to be a sexy weekend alone with Jessica, like I had initially expected. Never in a million years had I anticipated needing to fend off the sexual advances of my girlfriend’s persistent eighteen year old sister.
There was no denying that everything about her tempted me. And yet, it was not nearly as easy as she was suggesting. I wasn’t about to have a weekend fling with Natalie behind Jessica’s back. Even if she was throwing herself at me whenever she had the opportunity to. At this point, I was certain this wasn’t some elaborate test of my faithfulness. Things would have never gone so far upstairs if that was the case. This was all Natalie, and I had to imagine this wasn’t just because she wanted to fuck around with some college guy. I wasn’t about to flatter myself like that; though I was attractive enough, there was no way Natalie decided on sight that she wanted to sleep with me.
No, she absolutely got off on seducing someone she wasn’t supposed to be with, and with someone who very much wasn’t supposed to be with her.
At least I was safe for now. Alone on the boat for as long as it took me to apply sunscreen to the rest of my body, with no major decisions to make for the time being. Maybe if I glued myself to Jessica for the rest of the day, I wouldn’t be put in any more situations where I had to resist Natalie’s advances. I was only human, and I didn’t always think with just my brain.
If she pounced on me out of the blue again, there was no telling how I’d react. So far, my track record wasn’t great where Natalie was involved.
