I sabotaged my parents’ condoms — and wound up with a little sister

Call it a breakthrough.

A woman on TikTok has gone viral for revealing the reason her younger sister was born — because she poked holes in her parents’ condoms.

The TikToker, known on the platform as Keely, posted the video last month as a birthday tribute to her sister, Sam, garnering nearly 7 million views.

“I’ve kept a secret for 25 years,” reads the on-screen text. “And think it’s time to share.”

Keely begins her divulsion by apologizing to her mother.

“Mom I’m so sorry,” she said cracking a smile. “I’m not sorry because Sam’s here.”

She explained that when she was younger, she and her best friend snuck into her parents’ bedroom and found a pile of condoms on the bedside table.

“I don’t know how she knew, [but] there were some shiny packets on the nightstand,” explained Keely, who had dissolved into giggles. “And [my friend] said what they were and told me what they were used for.”

It was at this point that Keely revealed that her mom also kept a sewing needle nearby.

Bursting into hysterics, Keely continued, “me and my friend poked lots of holes in the packets.”

Six months later, the fruits of Keely’s alleged labor were harvested when her mother made a surprise announcement.

“My mom told me she was pregnant, and I was so happy,” gushed Keely. “But years later my mom still says, ‘I don’t know how she happened. We were so careful.’”

It’s not known how the Keely’s family has responded to viral video.

The Post reached out to Keely for comment.

Several TikTokers were left speechless by the confession.

“The way you could not have waterboarded this information out of me,” laughed one user.

“The way I would have taken that to the grave,” joked another.

“If your sister is ever mad at you you can just be like ‘YOU’RE WELCOME FOR YOUR EXISTENCE,’” emphasized a third.
