My eldest sister Louise and her husband Colin visit my parents home at least twice a week. Louise and my mum are always off to my mums study room, going through work they're involved with. It leaves Colin alone quite often, but I never leave him to sit alone.
Making sure I wear the most provocative clothing, usually very short loose skirts, leaving off my knickers and tight t-shirts with no bra on. I purposely touch my breasts and have my nipples hard and erect. Then i'll sit opposite him and flash him my shaven pussy, knowing he can see right up my skirt and get a good look at my increasingly wet pussy.
When I see he's getting an erection which he does every time, I'll put my hand between my legs as if it's perfectly normal to do so, and stroke my clit.
Many times I've almost orgasmed from constantly touching my pussy and teasing us both. But so far I've held off, even knowing his cock is ragingly hard from his huge cock bulge. Sometimes he'll mention something about me being a dirty bitch, but mostly he suffers in silence. However two days ago I was especially horny watching him struggle to deny himself a look at my quim.
Leaving the room and walking into the kitchen, I was bending over to pull a try out of the fridge. t was then I felt Colin's hand reach up inder my skirt and feel my soaking wet pussy. Straightening up, I went to say something, but then felt his hot hard cock enter me from behind.
Holding onto my tits through my t-shirt, he began to fuck me and it felt utterly amazing. I'd never seen his cock, but it felt huge in my pussy. As my pussy got used to his size, I was just beginning to orgasm when we both heard my sister shouting Colin. As quickly as he'd entered me, he pulled out and I was left feeling frustrated. Probably just as frustrated as I'd made him feel for some time. And to top it all, I still haven't seen his cock.
he rest of the evening was spent trying to resume our liaison but unfortunately we couldn't re-enact what we'd done previously. I did manage to masturbate in front of him though, bringing not only a massive smile from him, but also his customary cock bulge.
They're both coming here for the Christmas break. Staying over for five nights. If I don't, but I'm sure we'll get the oportunity, to get to have him fuck me then, I'll just have to carry on teasing the fuck out of him.
It's something we both shouldn't be doing, but then he is far too good for my frigid sister.
