Of course not

"Well, that's one punishment down." Said 17.

18 looked down at Trunks, who was starting to recover.

"Looks like it's your turn, sweetie." Said 18.

"What do you mean? Didn't we just go through your punishment?!" Yelled Trunks, as he sprung to his feet. It was hard for the androids to take him very seriously with the way his dick bounced up and down as he got up.

"No no, honey." Said 18, as she grabbed the boy by the hair and lifted him about two inches off the ground. "That was your mom's punishment. You getting to jerk off was an award for being such a good little boy."

18 then lifted herself off the ground, and Trunks knew better not to struggle as she slowly flew him over to his mom. She sat him down right in front of his mom's feet, as Bulma started to comprehend what was happening.

"What's...going on?" Asked Bulma.

"Your son has one more task to complete before you guys get to leave." Said 18 "Judging by how pleased you were at my brother fucking you, it's clear that you don't get off too much. So Trunks is here to fix that."

"You can't mean-" Said Bulma.

"Oh, but I do." Said 18. "And if Little Trunks had manned up and volunteered for the first punishment, instead of letting mommy do it for him, he wouldn't of had to eat 17's cum while he was down there too. Now, Trunks, eat your mother out like a good boy. Make sure you lick up every last drop of my brothers cum while your down there too."

Trunks looked down at his mother's pussy. the wiry blue hair, was matted with cum. 17's load was clearly still there, and the thought of that disgusted him. He looked up to 18 with pleading eyes, but her cold stare told him that he had no choice. Trunks took a deep breath and knelt down and gave his mother's clit a lick. The bitter taste of the cum mixed with the taste of his mom's sex. He started going faster and faster as he realized that the quicker he was done, the better. To his dismay, he felt his dick hardening yet again, but it wasn't long before a familiar hand grabbed his dick, and started jerking him off. 18 was playing with his baby penis yet again.

Bulma gasped with pleasure as she felt her son's tongue on her pussy. The events of this day didn't seem real, her son, who she was so proud of, had been completely humiliated in front of her, and worse, she had helped. Now he was being forced to eat his enemy's cum out her pussy. She knew he would never be able to regain his confidence after this. She couldn't even comfort him when this was all over. There was no way he believe her words after he heard her admitting he had a tiny penis in front of their mortal enemies. The worst part? She was so turned on by this. She enjoyed seeing Trunk's pained expression when she called his dick small, she enjoyed watching 18 making him cum, she enjoyed denying him sex, and fucking 17 instead, and she enjoyed the fact that he was forced to eat 17's cum.

These thoughts were finally too much for Bulma as she started cumming in Trunk's mouth. Her back arched in the air as she couldn't help her loud moans that escaped her. His mom exploding in his mouth, made Trunk's cum for the third time today, as his penis begin to squirt, yet again. This time, 18 caught the cum in her hands. Trunks and Bulma then passed out from exhaustion, with Trunks head still between his mom's legs.
