Jilly sighed as she slipped her naked body into the steaming hot tub. There must be something wrong with me, she thought, as she was feeling extremely horny, and she had only just had a good long fuck with her lover Penny. Ah Penny. The delicious curves of her body, the soft tan of her skin, fading to milky coloured up between the tops of her thighs, the sweet taste of her pussy on Jilly's tongue as it was working inside her, the building tension of pleasure at feeling Penny doing the same to her...
