One-on-one encounter with a brunette in the restroom during a family gathering

During a family gathering, my girlfriend and I decided to sneak away to the restroom for some alone time. As we were about to get started, her brother barged in, interrupting our intimate moment. Frustrated by his intrusion, we decided to kick him out. But as he left, he let out a sly smile, hinting at something that could potentially spice up our encounter. Ignoring his insinuation, we continued our passionate session, until he returned with a surprise - his impressive, well-endowed friend, eager to join in. Initially taken aback, we soon found ourselves enticed by his sizeable member. After some initial hesitation, we indulged in a steamy encounter, with my girlfriend expertly taking care of his every need. The climax of our encounter saw him showering her with his release, marking an unforgettable experience.
