Jen couldn't get the thought of Susan's kiss out of her head. The memory of her fondling Jen's cup and its new contents didn't help. She fidgeted in her chair as the already tight athletic supporter kept getting tighter. Thoughts of Susan's curves kept popping into her mind unbidden.
Ryan was in the same class this period and Jen could already see some changes. His jersey had gained buttons and small but noticable breasts tented the clingy material. His hair had also started to grow out and the cuffs of his pants had raised a little and started to pleat. Jen wondered how Ryan could remain oblivious to the changes. It wasn't to long until they would be impossible to ignore.
The bell rang and Jen found herself hurrying to get to the bleachers. The thought of Susan taking care of her erection made her hornier than she had ever been in her life. She blamed it on all of the testosterone being pumped through her system and her new anatomy.
She found Susan waiting for her, her shirt and bra already on the floor. Without saying a word she expertly lifted Jen's blouse over her head, the fused buttons and changed material making the garment almost a jersey. She then unbuckled the shoulder pads and wriggled out, letting them drop to the floor. Jen looked down at the damage the transformation was doing to her figure. Her shoulders had broadened and she had developed more muscle mass but she still looked feminine enough to pass as a girl if she didn't flex. Her breasts had lost a whole cup size but from the grinding sensation between her legs she knew where that cup size had gone.
Susan licked Jen's nipple playfully before giving it a tweak and starting a trail of kisses down her hardened belly. When she reached Jen's skirt she lifted it to get ahold of the athletic supporter. With a quick yank she pulled it to the floor, allowing her new member to spring up like a flagpole and wave her skirt as a banner. Flipping the skirt over Jen's erection so it was out of the way Susan licked the shaft to the tip like a popsicle. Jen had to bite her lip to keep from crying out as the sensation shuddered its way up her spine. Susan then took the member into her mouth and began to bob up and down. Jen fondled what was left of her breasts with one hand as the other sought the back of Susan's head. She didn't even notice the churning sensation that had begun between her legs, too focused on being fellated.
