Speaking of responses I received to Craigslist casual encounter ads, I also once received one from someone who claimed that they were looking to start a family but had run into issues due to their husband's low fertility so they were looking for someone to donate sperm ... as nature intended.
A quick reverse image search revealed that they had "borrowed" a couple images of MILF Becca, a woman who makes amateur cuckold porn, see below.
I have to give them credit, considering what they were proposing, using images of someone who produces that particular type of content to catfish was a nice touch and I have to give them credit for showing slightly more creativity than the usual assortment of pic collectors, time wasters, spammers/scammers and predatory gays I typically received responses from. Though what really set my bullshit alarm off is where they said they lived, if you can afford a house in Vaughn, you can afford even barebones fertility treatments. And if buying a home has left you so broke you're turning to "alternative methods" to get pregnant, you might want to get a bit more money saved up because let's face it, kids are expensive!
And I'm not gonna lie, if it had been a real and legitimate offer and she had looked even remotely like that, I might have gone for it, with a few terms and conditions in place. I would have gladly submitted to any testing and screening as well as insisting that we met at least once before the wife and I spent naked fun times together. I'd want to gauge the husband's reaction. The one thing I still recall about the email I received was the statement, "I've always wanted a big family", leading me to believe if this had been a real offer and not an attempt to get me to sign up for an Adult Friend Finder clone or get a picture of my penis, it would have been the wife's idea. If I detected even the slightest bit of hesitancy from the husband, I would have respectfully declined the offer and told them to either look into fertility treatments or adoption or told them I would have been happy to donate my sperm only I would jerk off into a cup and they could have either used a home insemination kit or we could have done it at a fertility clinic.
I'd also need something legally binding in writing or on video from the husband, and get my own copy, where he acknowledged that all this was happening with his knowledge, consent and enthusiastic approval, specifically that he was fully aware that I would have been fucking his wife to knock her up. Because if they got divorced and it got messy, he could have just said, "My wife has been having an affair, the kids aren't mine and I can prove it!" And as the bio-dad, guess who's on the hook for child support.
Being it was on Craigslist, I also realize it might have been a scam too, whether it was the messy divorce scenario or going with fertility treatments/artificial insemination but "we're a little short!" In the case of the former, they would need to count on someone really naive and trusting because I'm going to need proof divorce proceedings are happening, though it won't be an issue because I'd have something from the husband acknowledging that he was fully aware I would have been having sex with his wife to get her pregnant. In the case of the latter, I'd tell them no, you're the ones who want kids, not me. You can also afford a house in an area where some of them cost upwards of $4 million!
