Monica does not want tons of testosterone, but a little bit larger, more physical body would be helpful to keep up with Brenden. She drinks a quarter of the potion from the test tube. "I'll save the rest for later and see what happens to me from this much." Monica laid the test tube on the table and goes to the foyer where she has a full-length mirror.
Brenden follows to watch. Monica feels a burning in her stomach and her entire insides. The potion works quickly to burn off the extra fat she had. She feels her muscles pulsing and getting ripped. Her body elongates and grows from 5'5" to 5'9". She can feel her hormones surging and she can think of nothing but sex. Brenden notices that her body has gone from curvaceous to extremely trim and buff. Her muscles are larger than before, but well defined and very feminine. Seeing the changes is getting too hot to handle, and Brenden cannot wait any longer.
The lovemaking moves from the sofa to the floor to against the wall. Monica has little trouble keeping up now that her libido has gotten a kick-start from the potion. They eventually fall asleep in each others arms on the living room shag carpet.
After a brief siesta, it's to the kitchen for more munchies...
