One idea in Ty's head was particularly enticing to him. He could cast aside his confusion about his sexuality that Eileen had brought on, and just indulge the feeling of wanting Eileen's cock.
Eileen looked confusedly at Ty as he saw the young man pulling off his T-shirt and undoing his cargo shorts before throwing them to the floor too. "Wait, Ty, what are you doing?" he asked in his new deep voice.
"I'm gonna do to myself what I just did to you," Ty replied nonchalantly. He stepped out of his underwear, standing naked before Eileen, and practically instructed his body. Turn into a girl.
They both watched amazed as Ty's body started to change. Ty moaned and felt intense shivers run through him, while Eileen watched in amazement, his cock seeming to pulse with excitement as he saw the teenage boy in front of him slowly start becoming a girl.
Ty's wispy body hair quickly vanished, making him look smooth all over, an impression reinforced as the texture of his skin grew softer. He shrank slightly, losing a few inches of height, his figure sucking inwards into a noticeable curve as his hips flared outwards. His muscles seemed to slim and turn more lithe, his hands and feet more petite.
The changes then moved up his body, his shoulders narrowing, his jawline softening and his larynx receding from his neck, his voice turning higher-pitched as a result. His hair lengthened and his lips grew slightly puffier- by now, Ty looked like a girl everywhere but his genitalia.
This now started to adjust too, and Ty was surprised by how intense it felt. As his nipples grew larger and more sensitive, he started imagining how good it would feel to have someone play with them or lick them or suck them. They soon became erect, and when he rubbed them a soft moan escaped his lips. A feminine moan from feminine pleasure, he realized, staring eagerly at the thick shaft between Eileen's legs. Continuing to rub his nipples, Ty began to sprout, soft breasts emerging on her chest. She felt Eileen's eyes staring at her in arousal and an odd satisfaction took root in her as she stared at the man's throbbing penis.
In response, Ty's body started to change the last masculine part of itself, and he felt himself embrace his castration and her new womanhood. His balls moved up inside her, and his scrotum tucked inwards and reshaped itself into vaginal lips. Above it, his penis shrank rapidly into a tiny nub, forming her clitoris.
Ty looked down and saw Eileen, who looked almost stunned by her new girl's body. "Like what you see?" she purred. Eileen nodded, and Ty wondered what she'd do with this DILF now...
