A sensitive amateur wife who wants stimulation mixed sex that makes both men and women cum

The wife who applied for this time in search of inspiration is Yui, who looks calm and serious. I'm surprised that he usually works as a mathematics instructor at a preparatory school. Yui's desire is to "develop a G-spot and cum over and over again." She immediately stimulates her G-spot with her fingers and cums instantly! Then she gets more sensitive and her first lesbian!! Furthermore, in the mixed threesome, she gets mad and cums with the male actor and actress.
