Mina watched intently as Joan took him in. She felt a mix of shock, arousal, and curiosity as Joan moved her hips back and forth. It was mesmerizing watching her, and Mina found herself getting closer and closer to orgasm just from watching Harker and Joan have sex.
Harker also watched, feeling aroused at the sight of Mina taking it all in. He licked and sucked her entrance more fervently, pushing her pleasure and arousal higher.
He felt Joan's tight walls squeezing him. It was a bit difficult to get used to it compared to entering a soft and wet pussy, but he soon found that it was enjoyable this way. Once her ass became wet and lubricated enough by its own slick, it felt easier to push all the length that got swallowed whole by her insides.
Joan continued to demonstrate, her body trembling with each thrust. She guided Mina on how to move and use her hips, the speed, and the pressure.
