Yozura gets cock all the time. Sena hasn't even seen one yet, outside of porn. She can't let yozura be better than her at anything, so she gets a cock, and puts it through its paces.
After my first tease was so well received I created an Eos version of it with difficulty levels, optional fetishes, over 300 pages and 20 different endings! Enjoy and have fun edging!
