This was a few years ago, I (M25) had a very cute girlfriend (F28). She was physically a stereotypically cute blue eyed blonde with round innocent face. Let's call her Anna. She had a lovely natural body. Beautiful tits. She looked like a model.
And she got some kinky peaks. She enjoyed making me uncomfortable, specially in public places. As an example, she might start rubbing my thigh and whispering to my ear how she wanted to sit on my face while we were on a bus. I used to blush and get nervous, cause I'm so easily aroused I get hard within seconds.
Anyway, one summer we began going super early in the morning to a beach near the city. It was working days and we were totally alone for at least 2 or 3 hours. Once, we go swimming as it was hot even for 8 in the morning and of course we began playing, kissing and at some point Anna grabbed on my hard cock. It was always hard before she looked for it and she loved it. We kept kissing and I knew just what she wanted. I wrapped my legs around her and she pulled down my swimming shorts to get a better hold and start stroking. I looked down and said "Fuck". I loved seeing her soft little hands on my cock.
She starts stroking as I looked for her breasts under her bikini. Anna turned her innocent look into evil, enjoying my reactions and making me moan as she kept going faster and faster until a blob of cum came from my dick. Her evil face turned again into innocent smile, she kissed me and head out of the water
I was amazed, but after that we just kept on with a lovely calmed beach morning.
So the next week her mom decided to join the beach day. Anna was very discreet with me whenever her parents were around. No kissing, not even holding hands. So I assumed that wasn't going to be as fun as the last time.
When we arrived and set the umbrella and all, Anna and I went for a swim. We asked her mom, but she wasn't feeling like going into the water just yet. I think she wanted to stay with her book.
So we get into the sea, we were just having a bath and chatting. We were covered by the water up to our necks. At some point she got closer to me and said: I want to jerk you off
-What?? Your mom is right there
-She won't notice, keep your voice down.
Anna asked me to face to the coast, and stood in front of me. She commanded me to wrap my legs around her waist just like last time.
Of course I followed others but I was so 't wearing them during the bath. I could see where her mom was, but couldn't tell if she was looking at us.
-Don't you want me to make you cum in front of my mom? - said Anna with her beautiful innocent smile and her fucking evil look.
I wasn't able to say no, I was already hard when I wrapped her with my legs and by the time she said this I was so lost into her control. I was her toy.
She asked me to keep a straight face but at the same time kept teasing me while reaching to my cock. She pulled my shorts down, just enough to take my cock out and began stroking with both hands.
I was so afraid of her mom catching us but so thrilled with such a slutty beauty just jerking me off.
There was no innocence any more, she kept going biting her lower lip and dirty talking.
-You are so naughty, with your big dick out in front of my
-Yes- I said with a heavy breath
-But don't make it too obvious - she said without ever stop stroking me.
I wasn't able to say more than a word until I could articulate:
-Fuck, fuck fuuuck I'm cumming
She furiously stroke with a smile even after I burst all my milk away. Right after said she was getting out, she was getting cold
-You wait a little bit and relax, you are still hard.
I stayed there floating some minutes. I felt so light after all the cum she pulled out of me.
To this day, I never knew if the mom realized. We had some sandwiches after and called it a day.
