Carolina finds out

I got my cousin Gloria pregnant and she is in a lesbian relationship with my other cousin, Carolina. We haven't told her yet and we didn't plan to until today happened. Gloria came over to talk about the pregnancy and an hour in, we had sex. After that, we cleaned up and got dressed but Gloria didn't put on her panties because I rub it whenever we do something. We were sitting on my bed discussing about stuff then the door rang. I wondered who it was so I opened the door and to my suprise, it was Carolina.
She angrily yelled "Where the hell is Gloria?" as she stomped inside.
Gloria got up "baby, I'm here with John, what's up?"
"Why are you here? You're cheating on me, aren't you! I followed you because you've been acting strange the past couple days, I thought something serious was going on and it turns out you wanted dick!"
Then Carolina turns back to me " and by the way, arent you engaged?"
She turned back to Gloria and Gloria said "no baby, I would never cheat on you, I was just hanging out with John".
Carolina smiled "really?"
"Really" Gloria said as they kissed.
My boner was arising so I took the opportunity and hugged them. If I have sex with both of them right now, Carolina will think the baby was concived right now. Carolina felt my boner touching her.
"John, are you turned on right now"
"... maybe..."
Carolina turned around smiled and said to Gloria "hey baby, should we fuck John?"
Gloria seemed to get the gist of what was going on so she walked over and grabbed my groin while rubbing Carolina.
We quickly removed our clothes and soon enough, I was fucking Carolina's juicy ass. I was trying so hard not to cum. When I was starting to feel it coming up, I switched to Gloria and came in her.
Carolina just stared into the mess and said "baby, please tell me you took your pill"
