DASS-557 An aroused, uncontrollable erection. A busty girlfriend, Marina Ikeda, is taken by a muscular, well-endowed man.

Marina had a boyfriend, but she had never known the appeal of a muscular man. A man who had never understood the appeal of an erect penis. The two of them became aroused, excited by each other, and found themselves drawn together in mutual understanding. Their overflowing excitement kept stimulating one another, and although they knew it was wrong to their partners, they could not hold back their desires and were consumed by their passion.
