She's a newcomer to this whole lifting weights thing, but a background in soccer and lacrosse certainly gave her a jump start. This is Gabby's first summer with a "beach bod" and she's proudly showing it off, but she's noticed something else has been growing along with her muscles. Each time she lifts heavy, she gets a raging hard on, that's a given. By the end of her set it's twitching and bucking, ready to fire at the slightest touch. But the kicker is - each time she pumps herself up without touching her cock the entire set, it seems to swell a little bigger than the last time. In fact, Gabby knows this because she uses the label on her shaker bottle to measure. When she's at the gym feeling totally pumped - like her cock is as thick and full as it's going to get - she simply holds the bottle next to the bulge stretching down her leg, and yea... it's definitely getting bigger.
