In Tokyo, we approached two friends - a college student boy and girl. We conducted a surprise negotiation with them! They agreed to try giving each other a handjob for the first time ever, surrounded by mirrors in a private room. The female friend was extremely sensitive; her clitoris became aroused just from rubbing against her male friend's fully erect penis. As they engaged in their first-ever handjob experience together, they eventually broke through their friendship barrier and had their first intercourse while still clothed. It was a passionate and intimate moment filled with mutual desire and exploration.
