Sorry a long story short. I've been with my partner 10 years, her mum had her really young and is only 10 yrs older than me. I still remember that day 10 years ago meeting her and she just looked like a hotter mature version of my partner. I remember I can't stop perving on her all day. Well it's been 10 yr since than and we have a really good mother/son in law relationship. We always talk a little flirty and the misses doesn't think anything of it because it's her mum.

Here's the issue! My misses went to sleep before me and her mum. Atleast an hour or so had past and I could feel myself getting closer to her mum on the lounge. Fully unintentionally I feel.

Another hour past and I look beside me and her mum is fast asleep with just a silk nighty on. I could just see a nipple popping out and you could tell she had no panties on as I could see every aspect of her pussy through the silk.

I couldn't help my self but just shuffle just an inch or so closer I can just feel her touching my leg with hers., by now she is starting to lean towards me still fully asleep. Now her pussy is there in full site and I just start to feel myself getting hard!

I'd been waiting for a moment like this for so long I got so hard so quick! She starts stirring and I'm thinking fuck I've just blown a 9 yrs relo for a fantasy I couldn't control myself from, nope she just switches the way she is sitting and now I've got my hard cock in my hand and my misses mum now has her head lying right next to my throbbing cock. I know I should have played dumb and woke her up but I was so ready to risk everything

She is that close to my hard cock with her mouth I just ever so slightly rub my knob on her lips, fuck they were so soft on that first touch! All of a sudden I feel my cock getting swallowed by her wet soft mouth. All this is happening and she still isn't fully awake.

She started to wake up as she is sucking on me, I don't know what it was but I seen her open her eyes look at me and continue to suck me off. I couldn't control my load and I blew in her mouth.

Now I'm sitting here with my GFS mums mouth filled with my hot juices and fuck I have never ever cum so hard in my life. So puts my cock back in my pants and sits up and I'm thinking I'm a goner she is gonna tell her daughter. I've fucked up.

Well no, turns out she thought I was her husband and didn't realise until she put my cock in her mouth that I wasn't. She said it can be our little secret and now she wants to suck me again tonight!

• She did say she didn't mean to suck me off and she felt dirty doing that to her daughter's bf. I told her how I've been feeling and explained that's why I didn't stop her Straight away. She gets up still with my cum all over her lips and as she is walking away, turned to me and said this is our little secret and I'll be down to fuck your cock again tonight. She told me it's so much bigger than her man's

By far the riskiest and freakiest shit I've ever done but fuck it felt amazing 💦🔥💦💦🔥
