    placed his hand inside his gym shorts to stroke himself skin-to-skin. I know now, as I knew then, that I should have politely gotten up and excused myself at that moment. I should have gone to my bedroom, eliminated the temptation and masturbated in private. But I didn't. I would like to claim I do not know why I did not get up at that moment; but the truth is I was very, very aroused by this whole perverse situation. Despite all logic and reason to the contrary, I slowly reached down as Robert watched, spread my thighs ever so slightly, fingers between my legs, and touched myself through my panties. The gusset of my panties was very wet now, and my clitoris was very sensitive and erect. I watched intently as Robert arched his hips, raising his buttocks off the couch, and pulled his gym shorts down to mid-thigh, placing his erect penis in plain view. It was the largest penis I had seen, thickly veined, with a well defined head and a slight purple tint. I was estimating it was seven to eight inches, and was thick.

I was in awe the way the white ropes just suddenly appeared in the air before landing on Robert. I realized that I had never actually witnessed a man ejaculating like this before. I was so aroused. I was amazed at the strength, volume and distance of his ejaculate. At least four very large spurts erupted from his pulsing cock. Semen covered his belly and chest with a gooey mess. The fragrance of the semen filled my nostrils. I had never been so stimulated in my life, yet I could not reach and orgasm. As Robert lay back panting and sated, I got up and said, “Don’t move, I will clean this up.” I went to the bathroom to get a wash rag. I soaked it in warm water and returned.
