She's not really into boys

"K-T, well this is awkward... You see, I'm really not into boys. Dicks really do little for me, even ones so big they look fake like yours. The thing that really attracts me is a nice pair of tits. The bigger the better, nice bouncy mounds of flesh. We are good friends and I'm happy that you invited me here, but you should have told me what you felt for me before that." she explained.

"But... You had two boyfriends, you just said so? How come now, you..." he mumbled, feeling his heart tearing apart.

"Yeah, but none of them lasted long and they were very disappointing. They were bringing nothing to our relationship that couldn't be replaced by a good dildo and they were thinking more about their cock than me. I really want to try something new and even with that grotesque thing, you are pretty much the same." she explained.

" Dude, sorry for breaking your trip like this." apologized one of the girls. "It's a shame that such a nice one won't see any action."

"You know what? Not everything is lost." said the large chested one.

"What do you mean?" asked Lily. "I'm into big tits, not dicks, I don't see what could change in this situation."

"Listen sister, as much as I love my girlfriend, lover boy here has some very impressive piece of meat. Don't discard him because of other assholes with bad attitude and defective tools. Besides, what if you could have it all?" she asked.

"All what?"

"This country puts its entire research budget in stuff that support their theme of tourism. Natasha's tits were barely bigger than mine when she arrived. The sell those chemicals with awesome effects to help their guests be the best version of themselves while on vacation. And she took only one dose of it." explained her flat chested girlfriend. " I skipped on it because she likes my tiny perky titties too much."

"How would getting bigger tits help me?" asked Lily, trying to digest the information, not sure where the couple wanted to go on.

"Not you, silly. Him!" replied the couple in unison.

"Me?" gasped K-T, almost chocking.

"The best of both worlds, you get to experience something really new both amazing tits and a wonder cock, on someone clearly lovestruck for you. And for you lover boy, might be less fun at first, but you get first row tickets for two weeks of her sexual awakening and discovery." explained Diana, the flat chested girl.

The proposal on its face was outrageous. The possibility of growing a massive pair of tits was already outlandish enough. But to accept or even volunteer to do so on the very island where he would have to keep them exposed at all times, unimaginable. His humiliation knew no end and he had apparently lucked out, ending in the very place he wouldn't have to show more than he was ready to (losing his shorts right now was a bad example.), could he really risk losing that benefit? Worse, his aunt and his sister were on the island with him. So even if the effect were temporary enough to disappear before he left the island, they would know about it for sure. But the other side of the scale was the possibility of two weeks of wild sex with Lily and his lower half vetoed outright rejecting it.

"Lily... If I... If I did it... Would you, you know consider... Well... Dating me?" he asked her anxious about her reaction. She had been lost in deep thoughts since exposed to the information.

"What they say has some merits... It is a lot bigger than the ones I used before, I might find a used for it, maybe. If the boobs are big enough I might give it a try while we are there." she admitted. That she would even consider it was already a win, on him now to be on his best behavior with her for now and not ruin his chances.

The two girls were giving him some thumbs up.
