My boyfriend was getting so sick of my sloppy terrible blowjobs that he decides to put me through an intensive blowjob training program he invented. Blind folded and bound while on my knees, he begins to bring in a guy that I dont know and instruct me on how he wants me to suck him. He begins flogging my ass if he finds me getting sloppy. After the first guy glazes me with his cum, another guy is brought in, his dick even bigger than the first. With my boyfriend's instruction, I get him to cum as well. He brings in a third guy and thanks to my excellent training I get him to cum all over me in no time. I feel so well prepared to suck my boyfriend's cock that I beg him to let me give it a try
