Call it cuffing season.

A Virginia woman says she tried to conceive a baby with her incarcerated fiancé after he sent her his sperm in a plastic sandwich baggy from behind bars.

The TikTokker, named Nesha, revealed the shocking mail tale in a viral video, which has clocked up more than 5 million views.

Nesha’s felon fiancé, Twinno, is locked up for identified offenses and is set to be released within a year — but the experimental couple decided to try and conceive “for fun.”

Calling it “a crazy experience,” Nesha showed a play-by-play of detecting ovulation after she received Twinno’s speciman via the postal service.

She subsequently received a positive pregnancy test — which was later revealed to be a false positive.

A week after the store-bought test, she supposedly went to a physician who performed further labs to confirm the pregnancy, but all the results apparently returned negative.

“It was a little disheartening to hear,” she said in a subsequent video on YouTube, adding that she feared she “did something wrong” when trying to conceive.

Initially, she claimed she spoke with a specialist who gave her a 10% chance of the mail order sperm successfully impregnating her.

“She still encouraged me at least just to give it a try,” Nesha said. “So that’s what I did.”

On his end, Twinno deposited his specimen into the plastic sandwich baggy before mailing it by USPS.

It arrived in just two days at Nesha’s front door, and she attempted to impregnate herself in her home bathroom.

After the false positive, the pair will wait until after Twinno’s release to start a family.

“We’re not trying again, it was just for fun to see if it would even work,” Nesha declared.
