Escalate your deal with Melanie

After arriving home, unpacking the car, and putting the baby to bed, you, Greg, and Melanie get changed and cleaned up. The three of you are tired but happy after a day of fun by the lake. You sit down on the couch between Greg and Melanie, chatting about how much fun you guys had.

During a lull in the conversation, you decide to bring something up. "Umm, Mom... I wasn't sure if you noticed, but... This whole thing with relieving myself into your mouth isn't working out as well as I'd planned."

Melanie breathes out a massive sigh of relief. "Thank you! I couldn't agree more. I mean, swallowing your... Stuff... It just doesn't feel right--Or taste good. Really, a towel or tissue would be so much better--"

"Uh, no," you reply with a chuckle. "What I meant was, you spill too much. I think you need to really wrap your lips around me when I'm trying to relieve myself--Maybe even stimulate me with your mouth a little bit."

"...Oh." Melanie seems very let-down. She thinks for a moment before continuing: "But isn't that kinda like..." She glances between her husband and you, starting to blush. "Oral sex?"

You clap your hands together. "Yes! Exactly!"

Greg frowns. "Are you asking your mother to give you blowjobs? I think you're a little confused there, kiddo."

"She does it for you, doesn't she?" you ask him.

"That's different sweetheart," Melanie says.

"Yeah! And, uh, not really," he finishes, under his breath. Melanie shoots him a dirty look.

"How about this... Sometimes when Mom gives me a blowjob, she can give Dad one too," you say. "And I'll need it a lot, so..." You give Greg a knowing look.

"Absolutely not," Melanie replies. "I'm not giving my son blowjobs."

"Well, hold on, let's hear him out." Once again, the horny portion of Greg's brain overtakes any common sense.

"At the end of the day, it's a family decision. I say let's vote on it," you continue. "I vote yes."

"Well, I'm voting no. Obviously." Melanie looks at her husband.

"We did say we would do anything for him..." Greg shifts uncomfortably, clearly hiding an erection.

"Sweetie, please! Don't do this," Melanie begs. "It's not right--"

Greg wavers, but then glances between her full lips and the bulge in his pants. "I have to go with our kid on this one--For his sake, of course."

You smile as Melanie groans and sits back on the couch. "It's settled, then."
