After a bitter divorce Marlene got full custody of Sharon and Steve along with their younger brother Jim. Their selfish father didn’t even contest custody as apparently he didn’t want any kids hanging around to interfere with him and his new harlot. Steve’s mother will sometimes go off on a rant about men and how they want nothing but sex so as a general rule we never do anything at his house unless his mom is gone. Sharon is home sometimes but that’s OK with me as she swore to be discreet and always leaves us alone – or so Steve thinks.
What Steve doesn’t seem to know is that his younger sister has the hots for her big brother! Sharon has always mentioned things like that but we all just assumed she was pulling our legs. It wasn’t until her brother started fucking me that I saw how jealous she was and realized her so-called jokes weren’t joke at all! Steve has no idea but I knew that Sharon spies on us having sex whenever she can. Sort of like my dad but she does it to get off and could care less about my safety!
As you might imagine, I never told Steve about this but often after Steve has fucked me Sharon and I will sit down together and discuss it. Sometimes we get so turned on that we each start masturbating as we imagine Steve fucking each of us in an incestuous threesome. OK, I’ll admit THAT one is more than a little weird but any excuse to masturbate works for me! Before Sharon I’d never really thought much about incest in the past, most likely in part because I’m an only child, but it turned me on to listen to Sharon talk about how much she wanted her brother and then to see her masturbating as she called his name… that was just HOT! I’d never met anyone before who wanted to have sex with someone in their own family. While it seemed REALLY strange at first to have my friend getting off to thoughts of her own brother, I really couldn’t blame her. Heck, if Steve had been MY older brother I probably would’ve felt the same way!
Much to Sharon’s frustration though, Steve is NOT into the incest thing and so far as he’s concerned Sharon didn’t exist unless he was trying to get information about me. She’s all but thrown herself at him but the more she flaunts herself the more he pulls away from her. Well, at least one member of the family s normal!
As much as we masturbate together, neither Sharon or I have never even mentioned anything about having sex together. Given my infatuation with my boyfriend’s cock I certainly don’t consider myself a lesbian and other than some innocent pranks during a sleepover or girls-only party I’ve never even seen two girls doing it for real. Sometimes I wonder what would happen if either of us took the initiative and made a first move? I don’t think Sharon would resist given the way we kissed at her last slumber party although it didn’t hurt that my mouth had been full of her brother’s cum at the time! I’m not really turned on by the thought of sex with girls yet I enjoy masturbating with my friends – go figure! Then again, I masturbate with my mom and WE don’t have sex so maybe it’s not that big of a deal.
