I decided to visit my neighbor, Mr. Amakawa, at his house to ask him to teach me some exercises. My girlfriend, who is currently an active instructor, changes into a high-leg competitive swimsuit and begins to exercise...but of course, my crotch gets erect. Mr. Amakawa, who was curious about my swollen cock, suddenly sucked my cock in his mouth and ejaculated in his mouth. My cock still doesn't get erect. that
