This happened earlier this year, while on holiday with my two children.
I'll keep it short.
I'm a single mum and have two children, one son and one daughter, aged 16 and 15. We had gone on holiday, nothing fancy, just to a caravan holiday park.
Our caravan wasn't a big one, just one bedroom which they shared and a sofa bed thing in the living area which I used, plus a little kitchenette area for cooking, it was all quite open plan.
It was our second day, and having had little time to myself I'd started to get a bit hot under the collar. So I suggested giving them £5 each and going to spend some time in the arcades, which they did.
As soon as they'd gone I couldn't wait, I stripped naked and pulled the curtains. I sat on the sofa and spread my legs as wide as I could, pulling them back towards my head.
It didn't take long at all for me to immerse myself in a full on rubbing session. For some reason I'd brought my dildo with me, I hadn't planned to use it, I just didn't want to be without it if I needed it. After about 15 minutes I was reaching orgasm, holding myself on the edge for as long as I possibly could.
Just as I thought I couldn't hold it any longer the door to the caravan suddenly flew open and in they both ran, saying something about needing more money but pausing mid sentence. I froze. I had no idea what to say or do.
I managed to ask what they wanted, and when they asked for more money I quickly told them where my purse was. Unfortunately there was no money in there so I had to get up and go to my hand bag.
This may have been the most embarrassing part of the whole thing; having to slowly slide that dildo out of myself in front of them, stifling the whimpers as I did, so I could walk, legs shaking, over to my handbag.
Anyway, I gave them as much money as I could find and off they went. It didn't take me long to finish and I had a great orgasm, and a deserved one at that, but after I'd finished I broke down and cried. I felt humiliated.
I've never been so embarrassed. I like to think we're open and honest about sex, but being caught pleasuring myself is unthinkable. I've only told one person about this and they told me about this site so I thought I'd share it.
