Try to soothe her

You keep carresing her head with your right hand while you start to crawl on your back with her atop you towards the nearest pool wall so you can rest your upper body against it and use both your arms to hug and calm her. Once you rest against the wall you wrap your left arm around her and start soothingly talking to her:

"Hush Honey, calm down, everythings okay. I'm here for you."

She calms down until she tells you while sobbing: "Nothing is okay. I'm terrible towards you. I'm just some slut and asshole towards you."

"Honey I know you, you aren't a slut and definetly not an asshole. Please calm down."

"I'm definetly an asshole and a slut. You remember our first time? I told you that I'm safe and you can fuck me bareback and creampie me. I just used you to fulfil my biggest fantasy: Getting fucked by you and getting knocked up on my first time. You know what, I lied to you about being safe, heck I even asked you over on the most fertile day of my cycle. To make sure it was the first time that got me pregnant I denied your dick my pussy until I got an clear answer that I was pregnant. Once I knew you knocked me up I got so horny that I had you mounting me about half an hour later. And as you may have realized I get my best orgasms when I feel your cum jetting in to me. I'm sorry, I'm just such a terrible and egoistic girlfriend."

You hope she didn't notice your dick stiffen on her declaration, as you get aroused at the thought of knocking her up.

You continue soothing her: "No you are not terrible. You never told me that you are save, you just told me that it would be okay to creampie you. I'm just as much at fault as you. I just interpreted that you are safe. And if we make confessions about weird sexual fetishes I also have to confess some things to you: I get horny from the thought of knocking some one up or getting knocked up. I'm also have my best orgasms when I creampie someone. My fetishes are just as weird as yours. And if you wanna hear it, I will tell you that I forgive you the things you just confessed to me and I'm not angry."

She stops sobbing and looks at you with her teary eyes: "Are you serious? Do you really mean the things you just said?"

"Yes honey, I mean them all." You underline your statement with a simple kiss on her lips.

She starts to smile, but she also develops a worried face: "Thank you honey. But now we have a serious topic to discuss: What should we do about my pregnancy? Are we ready to become mommys?"

"Honey, I will be honest: I'm not sure if we are ready to be mommys already, but I wanna try it. I would love to have children with you. But don't let me pressure you into anything, I will support whatever decision you will make."

She really starts to beam now and starts crying again. Seeing your concerned look she says to you: "Thanks Honey, I'm so happy to hear that from you, these are tears of joy. And I just made my decision: We will be mommys, I wanna keep your child."

You simply kiss her on the lips, confirming her decision. After that you two lay in the pool together, simply cuddling for a while. Then you start to gently clean each other with the shampoo and bodywash provided by the bathing house. Once you finished cleaning each other you get out of the pool and dry up. Afterwards you make your way to the locker room, get dressed and leave the bathing house after paying your stay.
