While he grinned at you with his question, you didn't waste any time dunking him under the water. It took a little bit more effort to do, you thought.
He came back up a few moments later, sputtering and pushing his hair back.
Wow. Being wet seemed to make him almost attractive, rather than cute like a kid. You snapped the thought out of your mind quickly, he was your brother after all.
Chris looked a bit annoyed at your actions, but only for a second, before he was grinning again.
"Oh yeah, let's see how you like that!" He said, voice cracking a bit.
You were just gonna laugh off his threat, but before you could, your head was under water. What? Since when was Chris strong enough to do that?! Yeah, being in the water makes it easier, but not that easier.
When you surfaced, you realized you couldn't move your arms anymore. You turned your head as far as you could, and found Chris wrapping his arms around your middle, small biceps bulging out, holding you there.
"Aw, don't swim away yet, we're just having fun!"
That tone of voice... It seemed like he was toying with you, and not in an innocent way. Like he held the power here. You wriggled in his arms. What the hell? His grip was strong, it actually wasn't easy to break free at all. And it was a very weird feeling his armpit hair brushing against your sides. He was so close behind you, you could even feel his Adam's apple protruding into the back of your chest.
What really got your attention though... Was the feeling of something poking you much lower. There's... No way he's "excited" by this, right? He obviously hit puberty, and probably had erections by now, but why would he get one now?
Just random, right? That's really common, it must be. At least, you don't want to think of another option.
Regardless, you should teach this little punk a lesson. But how should you free yourself?
