The girl gasped as she felt Mareth's tail probing her entrance, letting out a high-pitched whimper every time it touched her clit.  Her hands moved almost instinctively when Mareth began to play with her breasts, though she forced them to stay at her sides and tried to relax as the sensations washed over her, quickly reaching an orgasm before the succubus even stuck her tail inside.  "Oh... gods, I didn't know it could feel this good..." she breathed, letting out a moan as soon as the tail entered her sex, rocking her hips with the motion.  "Please... don't stop..." she begged before letting out another loud moan.
