We are two busty singles who don't miss any experiments and are always looking for fun and adventure. Sonja is 32 years old, has long black hair, slender figure with bulging, non-hanging 80E and non-slip bottom. I, Karolin, am 28 years old, have long red hair, a sporty figure with round, firm 80D and well-formed bottom. When we go out, we like to show what we have and are often asked about our large breasts. We are a few years in the future and medical research has made some progress. The latest development is a device with which the gynecologist can determine the orgasmic ability of women. It works very easily, the doctor pushes a sensor onto the vagina, which after a few seconds shows the orgasm ability on a scale from 0 (not capable) to 10 (absolutely capable). Parallel to the sensor, the pharmaceutical industry has developed two active ingredients that influence orgasmic ability, one that has a strengthening effect, also called G-cream; and one that causes a decreased ability, or F-cream.
