Human observation: The erogenous zone is the erect nipples! A plump girl who is new to nightlife attacks her nipples and writhes in agony for the first time in one-night sex
A woman is taken home by a man who picked her up at a bar. She doesn't seem to have had much experience with this kind of thing, and she seems to have gotten carried away by the good-looking guy. She was undressed and her erogenous zones, her nipples, were played with and she was in agony! The other man also seems to be quite fond of nipples, and the woman knows the joy of attacking their excessive sensitivity. They shared the joy of toying with each other and fucked each other.
