I feel terrible and need to get this off my chest.

We found out we were pregnant and the only person we told so far was her best friend. The three of us go out to celebrate - The pregnancy was unplanned, but we feel we’re both at a stage in life where we are responsible enough to raise a child. Maybe I need to rethink that assumption.

So the three of us go out dancing and we were having a great time. The thing is her friend was always a little flirty with me and I usually gave it back to her. My gf would roll her eyes and laugh. It was a joke we all were in on… until we weren’t.

My place is close to the club so we all go back there afterwards. I make a nightcap for her friend and me. Meanwhile, my gf hits a vape pen, which makes her instantly tired. So she goes to lie down on my bed, and I tell her I’ll keep her friend company until her Lyft arrives.

As soon as my gf closes the bedroom door, her friend shoots me this look. The. Look. She bites her lip and places her hand on my thigh as she moves in closer. I feel my dick getting hard and my stomach turning with anxiety about what I might do.

She’s right in front of my face when she tells me about how good I look and how I’m gonna be a “hot dad”. I smile and don’t say a word. Then she leans in to kiss me. I kiss her right back. I stop. I pause to look at her. Then giving in to impulse I start kissing her but this time with more intensity.

After a few moments, more kissing, fumbling with clothes, we’re fucking on my couch. My body is there but my mind keeps drifting to my gf and my bedroom. I ask her where she wants me to finish and she says her pussy. I listen to her, dumb I know.

As the impact of what I’ve done is starting to register, she gets on her knees. She suck’s my cock off clean with a smile. I really have no idea what’s going through her mind. I’m her best friend’s baby daddy.

We get dressed and say our awkward goodbyes. I wash up and get into bed. I’m ashamed so I sleep with my back to my gf so she can’t see my face.

When I wake up, my gf is spooning me tight and kissing the back of my neck and I have no idea how I’m going to tell her. This changes everything.
