" Take, take, take, that is all you do. My mouth, my pussy, and when I ask for anal sex, you assumed it was my ass, right?" she said. Her voice was an...rier than I expected."Honey, I just didn't - never did think that-" Never thought you'd give yourself to me, you mean?" Not very nice, but the anger had left her voice."You're being mean." You're right honey, I'm mean," she said, slipping down the bed between my legs, jerking the sheet out of my lap. She sucked my cock into her mouth, went all. So while she didn't resist what I did to her, she didn't want to talk about it.Her attitude told me that all is not well with her. She's my older sister and while we didn't get along a lot of time, I still loved her dearly; and the thought of what I've done so far hurt her disturbed me.For the next few weeks, I didn't do anything in particular to pursue Abby. I didn't watch her and didn't seek to catch her in disadvantageous positions.But it all changed when I overheard a bit of a conversation. I could see how wet my cock was when I pulled it out of her & shoved it back in, she was starting to enjoy it & told me she was going to cum, I was still fucking her & she came she was shouting fuck I'm cumming fuck me u bastard, I could just the chair arm getting wet, I'm thinking this bitch is loving this, I then pulled out & missed her cunt hole my cock hit her arse I got see it so in a flash before her new what I was doing I push forward hard I was up her arse fucking her bum please no not. “Please we both know you don’t have any friends, your family wouldn’t even notice your disappearance until your school rings. And guess what? We took care of that, not to difficult just a phone call notifying the principal you would be away on holidays for awhile. And you don’t have the heart to destroy me; you’re too soft despite your prickly attitude. Now take a shower, eat your dinner and go to bed. We promise that the fun won’t start until tomorrow at least.” Spluttering in denial that no.
