No word from my papa after our first adult relationship.

I had an adult relationship with my papa on our second date the other day. He was good-looking and pleasant, we were very compatible physically, and the allowance was generous, so I’d definitely like to see him again. However, he still hasn’t replied to my thank-you message after several days. (The Line message is still unread.) I’ve had adult relationships with around five papas before, but this has never happened. This papa also seemed very satisfied afterward and asked me several times, “Will you see me again?” so I’m a little worried about whether he’ll contact me again. He lives in a different region from me, so I suppose all I can do is wait patiently and hope he gets in touch the next time he has a business trip in my area, right?..
