“What Is Your Dad Doing Here?!” Surprise Fertility Clinic Swap (Melztube Debut)

My friend and I just started working at a fertility clinic. Everything was going great, until we got our first two patients - our stepdads! There was no way we were going to follow the procedures to get their cum out, but we also didn't want to get fired on our first day. The doctor could tell how nervous we were, so he let us swap patients: she'd deal with my dad, and I'd deal with hers. The only condition was that we had to follow all the doctor's instructions, or else... We didn't know this clinic was so unconventional. We even had to use our mouths to get their cum. Don't they have machines for that or something? By the time the doctor said "emergency penetration," we were way too into it to back out. In fact, we were ready to swap again and willing to do everything to get the best semen samples.
