Ben was so engrossed in the kiss he didn't notice Tricia's actions, nor did Ben react when Tricia unbucked his belt and unzipped his pants. By the time Tricia reached for Ben's pants, the changes were beginning to take effect. However, the gradual alteration did have the additional benefit of increasing Ben's arousal, to the point that he did not realize the changes which were taking place. Lost in Tricia's embrace, Ben let out a slight muffled moan and breathed deeply as his body tingled and shifted.
While Ben was lost in his excitement, Tricia, on the other hand, was paying very careful attention to Ben. It was Tricia's first time using the remote on another person, and he wanted to observe every slight change, even as he took advantage of the situation to be affectionate with Ben. While Ben didn't change as much as Tricia did when he became Tristan, the alterations were quite obvious. Under Tricia's gaze, Ben's facial structure shifted and became less rugged and more elegant, his lips fuller and his chin, now free of stubble, coming to a smooth point. His hair didn't lengthen, but framed Ben's face to give him a tomboyish charm. Although he didn't lose any height, his body shrunk from its study muscular physique to a more wiry hourglass look, his clothes hanging on him except across his now growing breasts and hips.
Even before the changes were completed, Tricia reached over and began undoing Ben's pants, lowering them just as his genitalia began to shift. Tricia leaned into Ben, who let out a gasp as his genitals began to draw into his body. Too ecstatic to react, Ben clutched at Tricia, who guided his erect member into Ben's forming vagina, and as her body finally completed its shift, Ben and Tricia came together in utter pleasure.
Finally spent after quite some time and panting for air, Ben collapsed into Tricia's arms, finally realizing the extent of what had occurred.
"What happened to me?!" Ben asked quaveringly as she pulled her pants up, just as shocked by the loss of her manhood as by the high pitch of her voice.
"Looks like your wish was granted," Tricia smiled gently, pulling his own pants up with one hand and holding Ben with the other, just managing to carefully zip them up and button them.
"Oh my god, oh my god..." Ben started to panic, finally processing the ramifications. "This can't be happening, this isn't possible..." Ben hugged herself as she fell, Tricia barely managing to catch her and lower her to the ground.
"I guess we were just meant to be together," Tricia tried to comfort Ben, lifting her now tearstained face.
"But I'm a guy! I have a girlfriend...oh my god, what do I tell Holly? And what about school? I can't go back like this!" Ben sobbed.
"Listen, whatever happened here must have happened for a reason," Tricia said evenly. "Tell you what, why don't you come back to my cousin's place with me? She's out of town for the next few days, and it'll give us some time to figure out what to do."
Eyes a bit glazed over from the shock, Ben looked up at Tricia and...
