Nothing

"Oh no oh no oh no oh no." you hear, as the door to your sister's room opens slowly, you see her walk out, hands covering her private areas. "Oh honey what are you doing! You can't cover yourself" your mom says immediately, not caring that your sister is obviously distressed. "MOM! I can't go out like this! I need my clothes people are gonna make fun of me" she responds. "Welp, that's just too bad, now quickly uncover yourself, or you're gonna get hit with one of mom's spankings!"

Sofia immediately uncovers, both her and I know that mom's spankings aren't to be messed with. I also get my first good view at her naked, while she may be my sister she is still quite attractive! Her D cup breasts are too good I just can't get my eyes off them "Awwww look at my two kids being naked on naked week, who could I thought I would get this lucky." she says, somewhat mockingly. "Say, while I'm making breakfast, you two should have some 'fun' together." "Mom? What are you going on about? What 'fun' do you mean?" I say, worried about what she might make us do together. "Have sex of course" "WHAT! I can't have sex with that loser" says Sofia, not knowing how hard my dick was getting. "Well rules are rules, and don't be so mean to your brother" mom replies. Mom looks over at me and sees that I've been staring at her breasts for quite a while. "Alright, how about this, since Joseph loves your breasts soooooo much, you can give him a boob job, we can save the real sex for later this week, ok?" "No mom I ca-" Sofia can't fully complete her sentence before seeing mom's face.

Admitting defeat, Sofia walks over to me and neals down. "Well you're already hard enough as is, quite disgusting since I'm your own sister but let's just get this over with." She grabs my dick and pulls it under her breasts, despite how long it has gotten I can't quite see it anymore, before the tip peeks out from in between her tits. She starts bouncing up and down and I feel it, my first time ever getting a boob job and it feels so good. How'd Sofia get so good at this? She has to have practiced a lot with the amount of time I've seen her go out with boys from our school. "Mmmmm" I moan in delight, her breasts rubbing up against my dick is some of the best I've felt in quite a while. I quickly burst, spraying ropes of cum all over her face. "Ewwwwww, you could have warned me, you're so gross" "I would have made sure it gets on your face anyways" says mom from over the counter, hearing everything that's been going on for the past few minutes. "Breakfasts ready, so sit in your chairs and eat! I've attached some dildo's to your seats, so make sure they stay in your ass the whole time while you eat." This news shocked you, you've never had a dick in your ass before. "Mom I can't have anything go up my ass!" You say in protest. "What, you scarred?" surprisingly, Sofia said that, she must know what it's like to have something go up her ass. Mom replies by saying, "You could always just skip breakfast, but that thing's going up your ass at some point, so might as well get used to it."
