Sex - Cowgirl

You switch the position to cowgirl.

"I...I don't know about this..." Xiu stammered as she lowered herself onto your shaft.

"Oh, don't be such a prude, you can get used to it." you tell her with a grin before giving one of her tits a brief squeeze. Xiu ends up complying as she rides you at a steady pace, slowly getting used to being on top of you.
