Lilly kept groping her breasts and pussy for a few moments longer, before she grunted in frustration and stopped. She couldn't get into it with Mikael constantly invading her fantasies. Sure he was attractive and well-built but he was still her sibling. Frustrated, she turned off the water and stepped out of the stall. Mikael saw her in the nude in all her glory, fully exposed. His little sister's body was magnificent, the equal of many a model or girlfriends he had had. The nude girl went to grab a towel, her breasts bouncing beautifully, she became dangerously close to spotting Mikael.
As she heads to the towel rack, she sees him through the crack in the door, his eyes looking at her body, his monster cock in his hand. Mikael darts out of the way, heading back to his room and hoping she didn't see him.
Lilly quickly dried herself and grabbed a change of clothes, before she headed to Mikael's room. She knocked on the door, and headed inside if it was open, 'Mike, I saw you watching me, you can't deny it! What were you thinking?!'
The big guy is lost for words. "Lil, I-I..." He breathes. "Sorry, sis. I dunno, I got worked up when we were working on the spell, and you just looked so damn beautiful. It won't happen again."
Lilly went up close to Mikael and poked his chest, 'So you thought you'd just watch in the shower?' She shook her head, 'You don't need to perv on your sister. You could have any girl in the city if you wanted.'
"Thanks for the vote of confidence, but you're not just 'some girl'." He shuts his mouth, fearing that he said too much.
'Not just some girl? Yes, I'm your sister,' Lilly huffed, 'You really shouldn't lust after me. It's wrong.' She grabbed her boobs for a moment, 'They're just breasts, Mike. Every girl has them, mine aren't even that large for you to obsess over.'
She sees a flash of lust in his eyes as she touches her breasts. "I know, damn it... I just... You're so perfect, Lil." He stands. "C'mon, if you were in my place, you'd be doing the same thing." He grins, gaining confidence. "In fact, tell me, it wasn't me you were thinking about when you were touching yourself in that shower, was it?"
'I'm not perfect... don't be silly. And I wouldn't perv on my little sister, Mike,' Lilly shook her head, before she blushed, 'N-No, why would I?' She folded her arms beneath her breasts, 'And even if I was thinking of a big doofus like you in there, doesn't make it okay for you to watch me and... beat that huge anaconda of yours to me.'
"Why not?" He looks into her eyes. "Eh? I get the feeling that you like looking at me, and I sure as hell like looking at you. What's wrong about it? No one's getting hurt, and let's face it, you've always liked being watched."
'What's wrong?' Lilly looked confused, 'You're my brother! Look, teasing you and you checking me out in my sportswear is one thing. But you sneaking to the bathroom to watch me shower and masturbate to me is a whole other thing.'
Mikael's expression softens, and he nods. "I'm sorry, sis. I don't ever want to make you feel uncomfortable, or unsafe. I won't do it again, you have my word." He gives her a reassuring look.
'Good,' Lilly nodded, before she smirked, 'But you know... this is really unfair. You saw me naked without my consent.'
Lilly smiled, 'You better be.' She pondered for a moment, before she lifted her top, no bra beneath. Her breasts were a perfect handful, which was quite large given Mikael's large hands, rosy nipples crowning them. She giggled, 'There... now you've seen them with my consent. They're just breasts, Mike. No need to perv on me to see them.'
He blushes, looking up at her aghast, confused and turned on. "S-Shit... Lil, what are you..." He chuckles, realising that she's teasing him again. "What happened to 'it's wrong, you're my brother'?"
'It's wrong to perv on your sister in the shower while masturbating,' Lilly grinned, 'But if your sister shows you her breasts on her own? Not that wrong. Maybe seeing them without anything sexual happening will get it out of your system. As I said, they're not so special that you'd need to sneak around and masturbate to them.'
"I think you're underestimating them, but whatever." He chuckles. "God, this has been a weird day." Mikael flashes a grin. "Well, since you've shown me yours..." He stands, and places his hand on his zipper as if he's about to pull out his dick, before watching to see if she fell for it and reacted.
'Go ahead, I've seen your chest plenty of times...' Lilly looked shocked as he went for his zipper, before she shook her head and shrugged, 'Pull it out then. It's just a penis, I've seen plenty and I don't lust for my brother. Doesn't bother me a bit.'
"I was just kidding, sis. You sure?" He shrugs. "Fine, then." Mikael undoes his pants, freeing his length to spring out towards Lilly, very much erect.
