SCPX-495 - Absolutely cannot refuse!! Debut sex with a Yari-man Yankee's temptation.

Planned by my sister and her friend, who is rumored to be a sex monster, a divine situation where an unavoidable happy erection is inevitable. The target was me, who knows nothing about sex because I only study, chosen by my sister's friend, a Yari-man & Yankee who loves to devour virgins. In a private space planned in collusion with my sister, a true nymphomaniac and excellent gal comes to tempt me!! The invitation from the Yari-man Yankee GAL is absolutely irresistible!!
