My girlfriend's horny lover craves cunnilingus on the couch

My girlfriend's friend, a total vixen, was over for a visit, and her boyfriend was eager to show her some affection. As they sat on the couch, he playfully asked if she'd ever experienced cunnilingus, igniting a spark of desire in her. She didn't have to think twice before saying yes, and as they began to kiss, the heat between them intensified. As she unzipped his pants, he revealed his throbbing member, which she eagerly took in her mouth. Meanwhile, she unzipped my girlfriend's dress, revealing her luscious pussy, which she eagerly began to lick. The sight and sound of their passionate oral pleasure sent shivers down my spine, and I found myself lost in the moment. As the friend reached her climax, her moans echoed through the room, driving my girlfriend to the edge of ecstasy. I couldn't resist any longer and joined in, taking her from behind as she continued to be pleasured by her friend.
