Sister’s underwear picture message Part 3

I lay in bed staring at the ceiling, the nights’ activities both frustrating and exhilarating in a mix of emotion as I recalled the fun me and Chrissie had had. Mum had even asked me if I was OK as I had a ‘weird smile’ on my face as if I had been up to no good, but I convinced her I was fine and had behaved – something that Chrissie had confirmed, which for some reason, was then good enough for mum to believe! They had returned home about 45 minutes earlier from their evening out at which point both me and my sister had chatted to them in the kitchen as they told us about their night. Dad excused himself saying he needed the bathroom and a shower leaving mum and Chrissie gossiping about this and that. I would have gone to my bed myself but found myself perched on a kitchen chair with a drink as I ogled Chrissie who wore a slightly longer shirt than earlier, but the same tight knickers.

Neither parent batted an eyelid as it was pretty normal attire for Chrissie, but tonight I was taking a little more notice of her. I’m sure I even caught dad having a quick glance of his daughter when she bent down for something out of a cupboard making me smile to myself thinking whether he was picturing her not wearing them! Just as I had seen her not an hour ago!

Then my smile wavered as the guilt hit me of having lost my virginity to my sister, but only for a minute as the smile returned as I relived that wonderful body having taken my cherry!

“So you had to put up with your sister after she blew out Shaun!” mum said turning to me.

I nodded, but so much really wanted to add that I had benefitted because she had ‘blown’ me in a different way. I think Chrissie even cottoned on to my thought as she smiled rather wickedly at me when mum had said it.

Mum then walked over to me and put her hand on my chin, turning my face one way and then the other. “And no scratches or war-wounds so you two must have played nicely for once!” she said, laughing at her own humour.

“First time, eh Steven?!” Chrissie stated, giving me that look again.

I blushed.

“You two….. I don’t know,” mum said, “you see it’s much nicer when you get on and not fall out,” she continued saying with reference to just about every other siblings in the world who generally don’t get on at some point due to the fact, that was just how life was.

“We do get on mum” I replied, “it’s just that she’s an old cow now and then!” I said pulling a face at Chrissie.

Chrissie just stuck her middle finger up at me behind mums back, and mum just laughed it off taking another sip from the drink she had.

I gave mum a kiss goodnight and thought it best to leave now as Chrissie’s braless nipples were straining against her shirt causing a bit of a stir in my shorts so I headed up to my room, but not without seeing one last flash of her bum as she lifted her shirt briefly when mum wasn’t looking.

So here I am staring at my bedroom ceiling with another erection that I know will be a permanent fixture if I don’t get my head around my damn sister. I had stripped down to my boxers and had my duvet over myself to cover the evidence of my excitement, but as one hand flicked through the pictures of Chrissie on my phone, the other was gently stroking my cock. I could still taste her juices on my lips, even panicking a little whether my mum would have smelt them when I kissed her goodnight, but dismissed it as it had only been a quick peck on the cheek. But the image of Chrissie’s fingers embedded in her pussy soon put my mind back on track remembering this evening as one I would never forget.

I heard movement around the stairs as mum and Chrissie came up, doors opening and closing with the usual sounds of toilets flushing and taps running with the bedtime rituals.
