"Do you remember when Maverick was born? Where do you think the baby came out of?" Maci asked Bentley, who replied: "Belly."
After quizzing a mortified Bentley about what girls and boys have - "vaginas" and "peckers," he said - Maci explained the mechanics.
"No, it's a penis: Pen-1-5. So, a penis, goes inside a vagina," she said, as the three of them broke into fits of laughter.
"Okay, do you remember talking about eggs and sperm? So, sperm will come out of the penis and it will meet with the female egg and..."
"How does it come out?" Bentley interrupted but his mom said: "That's for another day."
She continued: "So the sperm will meet with the egg and that creates an embryo. It doesn't always work out but that's why we also need to use protection."
MTV then did a flashback to a pregnant Maci being asked by her friends how she told her mom she was pregnant.
"By text message," the then-16-year-old Maci replied before viewers were brought back to the awkward talk with Bentley.
"Girls are going to be weird pretty soon," Maci added. "You're going to be like 'hmm that's cute...' Or boys. "
"Whatever you like. It's ok if you don't like boys I'm just saying if you do. I always include because you can tell us anything.
'You're going to hear stuff from your friends, in school, in songs - you're going to be like 'what are they talking about?'"
Taylor said they'd prefer Bentley to ask them questions so they could give him "the right information" as Maci encouraged him to "talk to us, ask us questions, you'll never be in trouble."
"Holding hands and kissing on the cheek is fine for now though!" she quipped.
Straight-talking Maci recently butted heads with Bentley's dad, Ryan Edwards, for shading her Polycystic ovary syndrome awareness campaign.
The reality star and her first baby daddy have been caught up in a nasty feud with one another.
He in a recennt episode when he learned there is an entire month dedicated to the condition as he and his wife, Mackenzie, discussed Maci's involvement in a 5K run to raise awareness last year.
