Jake looked over the options presented on the computer. He grinned at Ben, and selected the "penis" and "increase size" options.
"Here ya go, Ben. One solution coming right up."
Ben grinned back, and then a look of shock came over him, as his cock began to tremble and swell, stretching downward, growing rapidly. "Jake, what the hell are you doing?" Ben asked, in surprise, as his penis grew to the size of a third leg, dangling obscenely, brushing the floor. "Jake, what the hell am I going to do with... this?" Ben asked, surprised, indicating his huge dick.
Jake laughed. "You're going to stretch it to the toilet so you can take a piss!"
Ben stared back in shock, but then a slow grin came to his face. He hoisted the big tube of manmeat, and reached forward, until he could rest it on the rim of the toilet. With a sigh of contentment, Ben let loose, his gigantic cock emptying his bladder quickly.
Ben then turned, pulling his big penis with him, and faced Jake.
