I have a girlfriend who is not pretty, but she is a very good person, and we have also thought about getting married. Today we went on a hot spring trip with her best friend. Jun is my girlfriend's best friend, and I was attracted to her from the first time we met. However, Jun already has a boyfriend and is now engaged. When I learned this news, an indescribable feeling of jealousy suddenly appeared in my heart. When Jun's boyfriend and my girlfriend fell asleep because they were drunk, I secretly followed Jun to the hot spring bath. When I looked inside, I was fascinated by her beautiful body. As if I was losing my mind, I immediately went to take her body. Even though I kept dodging, I could feel Jun's body trembling with pleasure with every blow I made, especially her wet pussy. Because I couldn't control it, I kept shooting cum into Jun's pussy over and over again, and Jun gradually got in tune with me, not dodging anymore. During the time I was here, we reached out to each other whenever there was a chance. After a while, my girlfriend said Jun was pregnant. Upon hearing this news, I felt very happy because I was sure the baby in Jun's womb was mine...
