Sister’s underwear picture message Part 2_(1)

I heard the shower start up in the bathroom down the hall as I lay on my bed still trying to fathom out what had just happened. How the heck had a picture sent in error from my sister just escalated into an orgasm for both of us?

I even wondered whether it had been a ploy by her in sending me the pictures on purpose, but then dismissed the idea, as she wasn’t usually a devious person.

As much as I enjoyed it, I was obviously concerned I had just had a sexual encounter with my own sister, but from the way my cock now stood erect again I guessed I wasn’t that concerned!

I grabbed some tissues from my bedside cabinet and wiped away the worst of the mess before getting off the bed and stripping my boxers. I screwed them into a ball making a mental note to stick them into the washing basket where I hoped they would dry out a little before mum put them into the wash, although it’s not the first time, I’m sure, she’s washed my undies knowing full well that they have cum on them!

I caught sight of myself in my wardrobe mirror and pulled a pose as if I had just won some major medal with a smile on my face that matched the achievement. I was impressed I had got hard again so quick, but having so many things now in my mind’s eye I wasn’t that surprised. So many firsts had just happened from simply seeing a sexy girl in and out of underwear, not to mention her then playing with my cock as I squeezed her boob before rubbing herself against me making me cum was phenomenal. Then as she pulled her thong off displaying her triangle of pubic hair above her slit was incredible making me even harder as I stood staring at myself.

My phone’s message alert made me jump, the screen lighting up next to my bed, so I turned and grabbed for it wondering whether it was Chrissie again.

But seeing ‘Mother’ on the screen made me panic a little before my brain realised that the shower was still on so it would hardly have been Chrissie anyway.

“Hi Steven, me and your dad have been offered dinner whilst we’re here so you’ll have to grab yourself something from the freezer to eat. I’ve text Chrissie too although I think she’s out later with Shaun. Be good and I’ll text you when we leave, love mum x”

I replied, tossing my phone back on the bed. That was the good thing with mum – she always let us know when she was on the way home which may be extra beneficial tonight as I wouldn’t even like to consider what would happen if she came home to find me and Chrissie in the position we was in earlier! Or dad, come to think of it.

That thought alone made me wonder what the hell we had been playing at, I mean, bloody hell, my own sister! But at least we had both gone along with it equally. We had both had the opportunity to stop it if we had wanted to without taking advantage, but obviously we had chosen not to.

And shit, was I glad.

I heard the shower stop and decided that when Chrissie vacated the bathroom I would grab a quick wash too as I was still a little sticky, even though my cum had started to dry. Cum that I had also sprayed up my sisters back which I saw glistening on her arse as she exited my room a few minutes earlier.

I waited until I heard her walk to her room before I shot into the bathroom where I somehow managed to have a pee before a quick shower to wash my matted pubes.

As I stood under the spray of water I wondered whether Chrissie had meant it when she said that if I deleted the pictures of her she would let me fuck her? Then I panicked that I didn’t have any condoms, plus the fact that I was still a virgin and maybe she wouldn’t want to do it now she’s had time to think about it or even whether I would be able to actually do it.

But the ache of my hard-on seemed to give me an indication that it would have to be a mental issue to stop me rather than it being a physical one!

I dried off and wrapped a towel around my waist before making my way back towards my room. As I passed Chrissie’s bedroom door I heard her singing along to some music she was playing inside. I hesitated outside her door and although it wasn’t closed entirely, I didn’t take that to be an invite to just walk in.

“Hey Chrissie, did you get the text from mum?” I asked, glad of the excuse to say something.

The singing stopped and the music got a fraction louder as she opened the door with her foot whilst brushing her damp hair with one hand and texting on her phone in the other.

Smiling at me she confirmed she had received and was just replying to mum’s text telling her that she had also decided to stay home having told Shaun she didn’t fancy a night out.
