OMG! Pregnant from the postman?

I was sent a parcel with toys that I was eagerly waiting for. When the doorbell finally rang, my hands were full and I asked the courier to bring the parcel in. I unwrapped the parcel straight away on my bed and was delighted with my new toys. I forgot about the postman and was amazed that he was still there. He outed himself as a fan of mine and I did him the favour of trying out the first toy right in front of him. That made him pretty horny and before I knew it, I had his fingering in my ass. As we didn't have any rubbers, but we both really wanted to fuck, we just did it without them. But I didn't want him to squirt inside me under any circumstances. Of course, he did it and then gave me some stupid jizz. Now I have to pray that I'm not pregnant...
