Masturbating around Housemate

I'm 27 and my female flatmate is 20. We've been sharing a place for nearly a year.

Of course I've masturbated a lot since sharing a place together but always in my room or shower and a few times around the house when I knew she was away for the night.

She'd always been very comfortable around me and I'd caught her naked a couple of times leaving the shower for her room and she's always just said 'Hi' and kept going. During a wank session thinking about her naked body and the way she was so casual about being caught naked, I thought that maybe she'd be just as casual about seeing me naked and I would get a big thrill about having her see my cock which is something I'd wanted her to see for a long time.

So one Saturday morning after a shower I stayed in the bathroom until I knew she was up and getting breakfast. You have to walk through the kitchen to get to my room. I worked up a semi erection, which wasn't hard to do, opened the door with heart thumping and headed to the kitchen.

She was sitting at the table eating cereal when she looked up to say hi. Her eyes didn't get to meet mine as they were locked on my semi hard cock making it's way through the room. I casually said hi and kept going. Once I'd reached my room I was so aroused I took a couple of pulls of my cock and I exploded. I knew I had to do this again.

The very next day I did the same thing. She looked hard at my cock and then up and me and as I was walking past to say hi she stopped me to ask a question about what I was up to that day!

I thought to myself quickly as to whether to keep going or stop so she can check me out more. I stopped and stood right in front of her. My cock nearly at her eye line and about two metres away. I said that I was planning on heading over to a friends house to watch football and have a few beers all the while knowing that my cock was growing by the second. She casually stared at my growing cock and said 'Cool...oh and nice cock. You should walk around naked more often.' I said 'Yeah no worries. I will if you do too.' She smiled and said 'I do all the time when you're not around but I thought you'd be awkward if I did while you were here.'

I started to get hard thinking about what was going on here. 'I'd be totally cool with it. Love being naked' I said.

'Looks like you do' she said pointing at my cock which was growing by the second.

'Sorry!' I said. 'Don't be embarrassed' she quickly said. 'It's beautiful. Can I see it completely hard?'

It didn't take long till it was when she said 'You should make yourself cum. That would be a cool house rule. Naked and if you get hard just play with your cock wherever you are.'

'How about here right now?' I asked.

'Please do.'

I put my hand around my cock and started to masturbate for her. It felt so fucking hot to be doing this in front of her and she squirmed on her seat as she watched.

About two minutes in and I came hard and strong and made a mess of our kitchen bench. It was one of the strongest orgasms I'd ever had.

I'm looking forward to being naked together tonight with her for the first time. Hopefully a story for you then about that too.
