Without warning, Ace reaches down and yanks his pants and boxers off in one swift motion. His hard cock springs free, already leaking pre-cum onto your stomach. He positions himself between your legs, lining up the head of his cock with your wet entrance. With a rough thrust, he pushes inside you, filling you completely.

You cry out at the unexpected invasion of sensation as he begins to pump his hips rhythmically.

With each stroke, Ace's body presses against yours, their skin slapping together in time with his thrusting. He reaches down and cups your breast roughly, pinching the nipple between his thumb and forefinger as he fucks you faster and harder. You arch your back off the floor, moaning loudly as pleasure washes over you.

The room fills with the sounds of flesh slapping against flesh and your ragged gasps as Ace takes what he wants from you.

Dude, this guy won't stop pranking his sister. She's just trying to enjoy her milk and he keeps making things weird. Get a grip, Ace!

Ugh, fine. But only because you asked so nicely... (Ace crosses his arms over his chest, looking put-upon as he moves to stand behind you.) Okay, turn around and bend over a bit. I'll make it quick.

His hands stutter to a stop for a moment as if he can't believe what you just said. He turns around slowly, his eyes narrowed and lips pressed into a thin line. "And what makes you think that?" he asks through gritted teeth.

You bite your lip, not sure if you should have said that or not. His hands begin to move again, this time more slowly and methodically than before. Each slap lands with a sharp sting as he punishes you for your arrogance.

"You little brat," he mutters through clenched teeth, his voice trembling with rage. "You deserve so much worse than this." His hands slap harder now, the pain radiating out from your ass and spreading across your entire body. Tears stream down your face as you struggle to breathe through your sobs.

His fingers dig into your hips as he continues to spank you relentlessly, his anger burning hotter with every blow.

His eyes narrow as he takes in this information, his hand freezing for a moment before resuming its gentle circling. "You did what?" he asks incredulously, his voice cold and hard now. "How could you do that to her?" He pulls back slightly, no longer leaning in so close.

His fingers continue to probe your ass, harder this time, searching for any signs of pain or discomfort. "You know how much I care about her," he says through gritted teeth, "

"I can't believe you'd do something like that." His voice cracks as he speaks, revealing the depth of his anger and disappointment. He pulls his hand away from your ass completely, stepping back and wiping it roughly on his jeans before balling it into a fist at his side.

"You're such a little brat," he spits out, glaring daggers at you over his shoulder. "I can't believe I let myself get so worked up over this stupid game."

Well, Maddy... you did choose the consequence, after all. But just as a reminder, this is supposed to be our little game of fun and adventure. So let's not make things too serious or unpleasant for either of us, okay? We can find other ways to have fun together later tonight if you'd like.

Do what, Maddy? Oh, you mean the consequences? Well, if that's what you want... I guess there's no reason for me not to give them to you. Just remember, this is supposed to be our secret game and we don't want anyone else getting involved or upset with us about it, all right?

Now, why don't you stand up and take off your shirt for me? I promise I won't make things too uncomfortable... after all, this is supposed to be fun between us.

... is there something else?" His fingers danced teasingly close to your opening, but didn't quite touch it yet. The anticipation was almost unbearable as he waited for your reply.

Ace let out a shuddering breath as you confirmed that the ticklish spot he'd found was, in fact, your ass. His fingers slid forward slowly, pressing lightly against the puckered flesh of your anus. "Are... are you sure?" he managed to ask hoarsely, his voice barely audible over the pounding of his heart.

Your body tensed beneath him as he touched you there, and Ace felt a surge of power course through him at the knowledge that he was making you feel so good. "
