Brianna is enjoying Jeff's breast, but something wriggled into her mind. she wanted these. she took another suck of Jeff's breast and got off the bed and went to the device. Jeff wanted to ask wat she was doing but quickly saw what was going on. His breasts quickly receded into him and Brianna's breast swelled, more and more and a bit more. Brianna started to walk wobbly towards the bed where Jeff laid and looked in awe. he could barely see anything else other than his girlfriends breasts. she barely made it to the bed and only managed to put her breasts on it. visible waves went through it as she laid them down on the bed as she laid her head on the sides of the grand breasts that had grown to half her size at this point.
