she lazes around for some time fondling happily her breasts. her stomach rumbles and Rachel gets up to get some snacks. She thinks to herself to watch some film or something, as she gets up feels herself wobble a bit. more than she expected to wobble. she looks down a bit and she sees her new "big" breasts. she isn't quite sure if they are as big as she was before lazing around. she shrugs and goes to grab some snacks. she watched a movie and fell asleep.
she wakes a bit groggy and notices the great weight on her chest. she gets up thinking she just didn't notice it before feeling the shifting weight on her body as she moved to get up. they were laying on her legs as she sat there. almost flowing over her legs. she hopes this is the "big" the witch revering too because she cant handle anymore growth. Hell, she cant handle this size probably. Rachel carefully started to move her hands towards her breasts that have grown from under her hoodie. she grabbed her breasts from under and felt the weight. they are quite heavy. she hops them up a bit. they give a soft slap when they hit her hands on the way down. she lifts her right breasts and lets it fall. an another slap and a wobble.
"feels pretty good" she thinks, but she hopes she they don't grow even bigger.
she gets up with a some attempts. arching her back to compensate for the change of center of mass. with a bit of adjusting she walks around. getting to her room upstairs was a small trail with the added mass. in her room she looks at her new form. curious she slowly undresses a little, but she decides to keep it a surprise for her self till tomorrow.
she puts on her pajama pants and attempts to put on her pajama shirt. she got it on half way and decides that it is a good enough. she cuddle up into her bed shifting herself to find a new comfortable positions ending up hugging her a pillow between her breast. some time later, after some gleeful smiling she falls asleep, having come to the conclusion she likes this kind of big.
