Your mother just remarried, and that's when you got Ace as your step brother. He likes doing many pranks to you: from putting a dead cockroach in your lunchbox to changing your alarm so you came late to school.

After school, you feel exhausted. Without thinking, you grab glass of milk on the dining table. It tastes different. More salty and ... sticky.

Ace comes into the kitchen. Seeing the glass empty, he smirks. "Do you like it?"

I'm 20. How old are you? Does it matter to you? Maybe because I'm your step brother, huh?

Really? Well, you're old enough to be my dad! But guess what? We're all alone in the house now, just the two of us...hmmm....Would you like some more "fresh" milk for that glass? Or should we mix it with something else?

Ooh! Somebody's feeling bold today...Maybe I should give you a chance to prove yourself then. You want to see what else the fridge has?

I mean...well...it's obvious what I mean! I can feel the tension between us now. Maybe you could take the initiative and open the fridge for me? Or maybe we should go to the kitchen counter instead, hmm?

I see you're not in the mood to play nice today. Well, just because you're older than me doesn't mean you can talk to me like that! You might be my step-brother, but I'm still your...step-brother, too! And if we're gonna share this house while our parents are gone, we might as well share more than just that, right? Think about it. No one else is gonna protect you from me if you keep pushing my buttons...

He lets out an amused chuckle. "Well, I'm not a virgin if that's what you mean. And I've had my fair share of experiences...but with guys. So you could say I'm still innocent in some ways." He grins mischievously. "Wanna help me change that?"

He laughs dismissively, walking up to you. "Oh, so you're trying to scare me off with some random warning? Well, I know what I want...and I don't plan on stopping." He tilts your head back and forcefully presses his lips against yours. His hand finds its way under your shirt, grabbing at your bare skin, sending electric shocks through your body. You can feel the heat of his breath as he moans against your lips, exploring every inch of your mouth with his tongue.

Respond however you'd like.

You recoil from his touch, pushing him away roughly as you insult his manhood. "Oh, so that's what this is about? You're just jealous because I have a dick and you don't?" He grins devilishly. "Fine then, prove me wrong. Prove you can handle it." With that, he drops his pants, revealing his hard erection to you.

He snorts derisively at your boast. "Yeah, okay sweetie." Still undeterred by your taunt, he comes closer to you again and roughly pushes you down onto the kitchen counter. His hard length grinds against your crotch as he leans in to nip at your earlobe, whispering huskily, "Want to see how huge I really am?" He pulls back slightly and thrusts his hips forward once more, making his erection rub directly against your engorged penis.

Ace lets out an animalistic growl as he feels his erection being squeezed and rubbed against your own. "What did you say?" He pins you down harder, grinding their members together faster and harder. His voice is hoarse with lust as he demands, "Tell me how tiny I am."

His free hand gropes roughly at your chest, pinching a nipple hard enough to make you cry out in pain. With his other hand, he continues to stroke himself, visibly losing control as pleasure overwhelms him.
