She was happy to oblige.

Towards climax again she started to shake, more noticeably than before. All of her muscles seemed to be vibrating, her nipples ached and pulsed, and she began to moan louder and louder until finally approached ejaculation. She doubled over shaking, her eyes bulged, her mouth wide, then she arched her back standing tall on her toes as shot her surprisingly huge load across the room. Her whole body throbbed for a bit and she collapsed onto her bed with a soft groan.

For a long half hour of afterglow she laid on her bed, her entire body sore as if she completed a full comprehensive workout. Finally she sat up, only to be startled by a substantial weight jiggling on her chest.”Whaaat? Woah what??” Liz did a double take at the two large, firm, incredibly round, newly grown C-cup breasts sticking straight out of her chest! Each startlingly large breast capped with nipples larger than thimbles.

“Holy cow!” Liz exclaimed, “I just grew breasts!” She couldn’t believe it. All those years she was flat she would have just settled for B-cups, she never thought she would actually be ‘busty’. She quickly got up to look in her dresser mirror, only to see her eyes just above the top of the mirror. “Holy- no way- I’m taller too?” she said excitedly.

Looking downward into the mirror she saw her pert round tits, pointing up and out, and below that was a toned, flat tummy with a sexy definition line going down the center of it. Below that, a full-sized cock and balls hanging at least 5 inches down, as long as she had just been erect. She suddenly got it, “I grow every time I jerk off.” She stood there for a moment stupidly thinking about it before a look of surprised understanding lighted up her face “I grow every time I JERK OFF???” She couldn’t believe it, but it seemed to be the case. She wanted to test it immediately to see for sure, but couldn’t… at least so soon.
