A friend of my mother's

Hi, this is my first short story, I hope you like it.
The story I'm about to tell is real, but for obvious reasons the names will be fictitious.
I was 18 years old at the time when this happened to me, I was in my second term of college, unemployed, and to make ends meet I started working as a computer technician, fixing computers. One day my mother tells me that her friend (I'll call her Paula) had problems with her PC and if I could go there to solve the problem. Paula, a beautiful crown, in her 50s, tall, white skin, dark wavy hair, full breasts, a body to be envied by many women.
I arrived at her house at the agreed time, Paula welcomes me politely and kindly as always:
- Hey Ben, good of you to come.
- My computer won't turn on.
She led me to the room that was a desk.
- Paulo (let's call her husband that) traveled, so back the other week, I was using his laptop and since he traveled I'll need to use the one from home.
A few minutes later I hear a scream:
- Please help me!
I ran to the next room where I had heard the cry:
- It's all right.
She tells me to come in that the door is unlocked. When I enter she is wrapped in the towel next to the bed and pointing to the mess, where there is a cockroach. She asks me to kill the cockroach please. At the moment when I go towards the cockroach to step on it, the cockroach moves a little towards Paula, who jumps on the bed. I step and kill the cockroach at the same time, but when Paula jumped on the bed, her towel rolls off her body, leaving Paula completely naked. We spend a few seconds both of us static with the situation. But quickly she bends down to pick up the towel and I turn my back to her. Completely embarrassed by the situation. But I couldn't help but notice what a delicious body she has.
- You can turn around.
When I turned around, I could see that she was upset about the situation.
I'm sorry, I'm also ashamed.
First of all, you don't have to apologize, you didn't do anything wrong, and second of all, you don't have to call me Donna.
Even with all that embarrassing situation I had become very excited and I think she had noticed because I was with a smile on my face, I did not realize at the time that she had noticed, only after the token fell kkkk, then she asks me:
- So, did you like it?
I'm asking you.
And she says to me:
- to see me naked?
I say it wasn't my intention, she says it's okay, it's already happened. She asks again if I liked it. And I say yes, she's very beautiful. Then she sits on the edge of the bed and says:
- so now it's your turn.
- My turn to what?
- From me seeing you naked, so we're even.
When I get nervous I usually start stuttering, and this time was no different.
- I... I... and and and...
While I was stuttering, she said,
She sits on the bed, stretches her arm and pulls my shirt up a little bit.
Seeing that I had no way of escaping the situation, I take off my shirt. (I forgot to describe myself at the beginning, I'm 1.80 meters tall, dark brown, light brown eyes, I've never had a healthy body, but mostly at the time, I was in shape, I was about 80 kg.) She tells me to continue, I take off my jeans. When she says:
- Let me help you with the rest.
I cover my stick with my hands, she says no and pulls my hands out in front.
- Let me see that straight.
Without being able to look at her, I feel her hand on my dick, when I look at her, she is smiling and says to me: "Come closer so I can see better". I take a step forward, standing right next to her, she licks the head of my dick, looking into my eyes with a cheeky face, at that moment I feel my legs shaking a little. She starts sucking me. At that moment I give myself over again to pleasure, hold her head with my two hands and let her do her job.
She sucks so wonderfully, and I was so horny with the situation, and before long I feel I'm going to make fun, I tell her I'm almost making fun, she tells me she wants to swallow you. It doesn't take long and I make fun in her mouth, she swallows it all. Then she tells me:
- Wait till the fun is over.
And I go to her bathroom, I was so horny with the situation that when she comes back in less than a minute, she looks at me and sees me already hard again, she smiles and says: "Geez, are you ready? I say yes, she says she was making a listerine cheek, because she likes to kiss a lot. Then I pull her by the waist, putting her body against mine. She is surprised by the footprint and smiles, then I start kissing her in the mouth. I put her on the bed, I open her legs, and I start sucking her pussy, all hairy. She whimpering with pleasure, after a while sucking, she starts climbing, kissing her beautiful belly, pleased to pay attention to her breasts, big boobs, beautiful, pink lips, kissing her neck, turning her lips to the side, I start kissing her cheek. Then she is surprised by the footprint and smiles, then I start kissing her in the mouth. I put her on the bed, I open her legs, and I start sucking her pussy, all hairy.
She tells me she hasn't enjoyed sex in years, she looks at her watch and sees the time, and she says she needs to take a shower to get out because she needs to meet a friend, and she calls me into the shower, we go in, and we take a shower together, even though I'm ready for another one, she says:
Boy, you're not tired, are you?
We finished the bath, exchanging kisses and caresses. I get dressed and while she's packing, I go to the desk to get my backpack and her computer since I finished not doing the service. She says she'll give me a ride, every sign q we stopped we kissed, she looked like a teenager. She tells me q things with her husband were not good, she was missing it. She left me at home and then we arranged other times to meet. But that's for another story, if you want I'll tell it later.
