Part 3 Nasty fiction

So Jim ended up testing how soon after masturbating was his cum still viable, he ended up finding out that if he masturbated into a lube bottle in a hotel room just before the guy and the girl got it on in the hotel room it was the most effective, and couldn't really be caught, no nasty vials of cum, nothing like that. He didn't rent the room in his name and he left as soon as he came. The dude lubed himself and the girl up with the water based lube mixed with cum and away they went.
Some guys were accused of being the father by girls but the dudes got a paternity test and they surprise supersize were not the father. They got a hair from the infant and tested it for Jim to prove he was the father but Jim never disclosed this.
It freaked some girls out that they could have sex on and off with one guy only for 6 months and end up pregnant without him being the father. But most girls were sleeping around so couldn't accuse just one person of being the father.

After Jim had indirectly fathered many kids he moved abroad and decided to step it up a level.
