Andy managed so shove his still leaking semi-hard cock into his trousers down one leg whimpering as his sensitive cockhead brushed against his cold leg. Jesse didn't speak a word. With a defeated look on his face he walked to the car. Undoubtedly his heart was filled with rage but uttering it would mean he would lose his last inch of dick. How would he manage to get through the week without it was beyond his imagination.
Andy was forced to use his brothers underwear to be comfortable with his new appendage it was eleven inches long even when completely flaccid. His penis more than made up for the difference in volume between Jesse and him. The next day Andy went swimming. His stretchy speedo barely fit around his appendage leaving a unimaginable bulge and even giving window to view his bare penis from from above. Jesse's girlfriend showed up and was mesmerized by Andy's penis. Jesse refused to go down to the pool even with his recently acquired loose fitting swimming trunks that hid his lacking manhood. He sat upstairs in his room while Karen sunned and stared at his little brothers cock.
Then it happened. As Andy climbed out of the pool and stood up his penis slipped out of the speedo through the right leg hole. Karen's crotch throbbed as she saw the thing in full display. Her crotch moist and her nipples erect she approached Andy. She grabbed his crotched and started rubbing it. Andy didn't protest. She felt it getting warmer in her hands but it wasn't getting erect quickly. She undid her top showing her bare above average bosom to Andy. Andy's penis started throbbing harder in a few moments it was fully erect. Karen squealed in amazement. Just as she was about the give Andy head Jesse poked his head out of the window, he had heard Karen's squeal. “WHAT THE FUCK ARE YOU DOING!? You fucking brat! That's my fucking girlfriend, I'll kill you!” Jesse realized it too late as his crotch stung. Andy moaned loudly his penis growing even longer. Now seventeen inches long Karen gasped. "It wasn't even fully hard yet!? Oh my.. it's so..." She grabbed it with lust in her eyes not caring about Jesse seeing her at all.
