Bulma has to make a choice

"Tell you what." Said 18, as she looked down at the two pitiful humans. "Since you two have provided us so much entertainment, we're actually going to give one of you a choice in how they're punished."

Bulma took one look at her son, and saw how awful he looked. A string of cum was hanging from his rapidly shrinking dick. She knew she had to step up.

"I'll...I'll do it." Said Bulma.

"Oh, A volunteer?" Said 17. "That's mighty brave of you."

17 looked to his sister and nodded, and 18 gave a sly smile in response.

"Here's what your punishment is going to be." Said 18. "You're going to have sex right in front of us all."

"Oh God, please, don't make me do that in front of my son."

"Well, that's actually going to be up to you." Said 18. "We told you, you get a choice."

"You can either fuck my brother." Said 18, as she gestured toward 17

"Or you can fuck your son." Said 18, as she grabbed a hold of Trunks by the hair, and pulled him to his feet. Trunks let out a groan from the pain, as Bulma tried not to notice her son's still soft baby dick flop as 18 pulled him up.

"So you either get to fuck in front of your son, or you get to fuck your son." Said 18. Her and 17 than began to laugh at the choice they gave the poor earthlings.

Bulma sat on her hands and knees, mortified. She must of been quite a sight sitting there wearing only her shoes and her son's cum. She looked at her poor son, and noticed that his dick was starting to rise again. It didn't take long for the androids to notice also, and they started pointing and laughing at Trunk's rising cock.

"Holy shit, tiny dick really likes the idea of fucking his mom, huh?" Said 18.

"No!" Screamed Trunks. "It's not like that!"

"I'm sure." Said 18, sarcastically "Before you make a decision, let's have my brother show you what a real man looks like."

17 then undid his belt and pulled down his jeans. It became apparent that he didn't bother to wear underwear, as his stiff cock quickly bounced out from it's prison. He slipped his jeans past his shoes before throwing them to the side. He stood facing Bulma, confidently, with his legs spread apart showing off his hard 9 inch completely shaved cock. Bulma looked at her two choices and couldn't help but notice that 17's dick was more then twice as long as her sons. Even Trunks took notice as he looked at 17 in awe, overwhelmed with the feeling of inadequacy.

"I can't bear to watch one of these monsters fuck you, mom!" Said Trunks, as his penis bobbed up and down. "Please pick me!"

The two androids busted out laughing again.

"Oh, you can't bear it?" Said 18. "More like you want to be the one to fuck your mommy."

"N...no." Said Trunks, as the androids continued to laugh.

"One more thing." Said 18. "When you tell us your choice, you have to say either "I want to fuck the big dick." or "I want to fuck the small dick." No explanations. You have to the count of ten."

"Mom, please!" Said Trunks, as the androids started the countdown.
