Despite having plans to hang out with her friend, she suddenly showed up at his place. Naturally, her real intention was sex. Too lazy to go out, she called her friend over and gave her directions—but sex started right in the middle of the phone call. While they were at it, the friend arrived. Even though she'd been invited, she awkwardly entered the room to find them together. The girlfriend, having called her over but not coming out to greet her, left the door unlocked, so the friend just walked in. Witnessing them in the act, the friend stood outside uncomfortably, while he climaxed regardless.
