The effects of the fertility supplement I took are getting stronger. Seeking answers, I find myself in the good doctor’s gentle hands again. She can’t keep her eyes off of the countless full condoms I brought and can’t keep her mind on anything except my swelling cock. I expose how unprofessional she is and give her the chance to offer professional assistance when she needs a fresh sample from me. I don’t know who is under whose spell, but I don’t even care anymore. As long as those massive breasts keep going. She gets the sample she is so desperate for, and a dozen or two more in the process. She rushes me out of the door before all the samples she collected can even begin to cool with a warning. Will I be able to lead a normal life like this?

The 10,000+ words covering part four of Experimental Medicine largely contain the following themes: Penis expansion, Excessive Orgasms with tons of delicious cum, endless titty-fucking, a seductive impossibly busty doctor fighting the urge to fuck me with questionable success, bra-bursting, breast expansion, ball growth, plentiful pre-cum, condom-filling orgasms, and a thirst that can only by quenched by one thing.

Reading Experimental Medicine in order is recommended.
