Somehow, while at Chris' house, all of the "Breast Grow" formula had wound up in Kevin's lunch. Kevin's body began to change almost immediately. The mass of Kevin's muscles atrophied, while his skin became soft and smooth. Long locks of red hair fell down over his shoulders as his face and lips became feminine. The tendons in his ankles grew tight, forcing him to wear high heels. And as Kevin's manhood began to shrink away, his ass and chest began to swell. By six o'clock, Kevin was unrecognizeable as a man. Knowing that he could not go home looking like this, Kevin asked Chris if he could stay over.
When Kevin woke the next morning, he felt a massive, aching weight on his chest. As he tried to roll over, he realized that he was naked, and two enormous, full breasts hung from his chest. In an attempt to roll over onto all fours, one of Kevin's breasts bumped into the couch causing milk to spurt out from his nipple. He reached up to cup his sensitive, engorged nipple with his hand. As he felt the wet milk that had come out of him, Kevin felt a different wetness between his legs. As his hand shot down between them, he realized that he was no longer a man at all. Instead, where his own manhood should have hung, all Kevin felt was a smooth, hairless, slippery opening. And it was so sensitive.
"You need to be milked" Kevin heard Chris say from a chair across the room. As she looked up, Kevin could only imagine how she must look on all fours, with massive tits hanging, and her hand buried between her legs. "That breast growth formula that you drank requires that someone other than you milk you at least twice a day" Chris continued. As he said this, Kevin could feel the pressure building within her breasts. She could also feel an aching wetness growing between his legs "I can milk you if you would like me to". The ache was so strong, that Kevin couldn't resist.
"Please milk me" Kevin heard herself beg. Still on all fours, Kevin watched Chris begin to walk towards her. As he did, so, he began to take off his clothes. He positioned himself behind her, and as Kevin felt Chris' strong hands grab hold of her round ass, she felt the heat from his hard member as it nuzzled up between her legs. Kevin shuddered, as Chris' rock hard cock spread her pussy lips apart, as he pressed himself into her sensitive, slippery, opening. As Chris began to thrust himself into her, he reached around with one hand and squeezed Kevin's breasts.
Milk spurted from Kevin's tits, as she thrust herself back onto Chris for relief. The release of pressure from within her aching breasts felt so good, that Kevin began moan out loud. Something in her brain began to associate that sensation with the feeling between her legs, because it didn't take long for Kevin to begin bucking her hips needfully onto Chris. But then a horrible thought crossed Kevin's mind. What if Chris took total control over her? And what would her family think when Kevin simply disappeared. As Kevin bucked her hips onto Chris, and felt her every tits swing with each thrust, she tried to voice her concern. But as she began to speak out, Chris squeezed her breast even harder than before. As hot spurts of milk erupted from her udders, Kevin was struck with mind shattering pleasure. "Moooooo" was all that Kevin could moan out as a quivering orgasm washed through her.
