An idea came to Ty. He'd wondered for a while what it'd be like to be attracted to guys as well as girls. The thing was, not only did he not feel that way, he also felt too scared to even try to explore the possibility. So, after some consideration of whether he wanted it, he took a deep breath and wished. I wish I was bisexual, he thought.
Nothing changed physically, but in Ty's head something felt different. He decided to test this change by looking up some naked pictures of men. Sure enough, he realized he felt attracted to them now. He still had feelings for girls, sure, but all of a sudden boys seemed just as enticing. Seeing a good-looking guy's handsome jawline, toned body, firm arms and legs, and big hard penis turned him on, and his own cock was hard in response.
Eager to fully indulge these feelings, Ty pulled off his underwear and started to jack off. As he shut his eyes, a million homosexual fantasies ran through his head. Grinding cocks against one another. Sucking a guy off, or thrusting against another guy's throat as he got sucked off. Jerking off another guy's cock, or having his own jacked by a guy while being kissed or praised. Holding another guy down and fucking his ass. Getting held down by a handsome man and pounded in his own hole.
Soon he started to ponder the possibilities of both men and women. Fucking a girl while a guy fucked him. Fucking a guy who was fucking a girl. Fucking between a girl's tits while a guy pounded his ass. Fucking a girl while sucking a guy's cock. Fucking a girl at the same time as another guy, her pussy trying to milk both cocks while they frotted together and ached to shoot their seed inside her first. Getting pegged by a girl (and that seemed like another enticing new world in and of itself) while a guy fucked his mouth. Two people fucking in front of him so he could palm off to their bodies- or someone else palming off to him fucking someone else.
As you might imagine, all these fantasies hitting the newly bisexually awakened Ty one after the other made it practically impossible for him to hold on. He felt his cock pulse and his balls twitch in his hands (imagining how much he'd love to feel another man's do so against his skin), and hot cum messily shot from his shaft (making him think what it'd be like to have that in his mouth, or leaking from his ass).
Ty panted heavily as he recovered from his aggressive masturbation, and wished himself to be fresh and able to cum again. He knew he couldn't wait to try some fantasies now.
