[Moyu] Isekai Mahoutsukai wa Kaerenai [A Cool Person]

A stranded otherworld mage who can't go home decides to make the most of his summoning, waking up entangled with a sweet, flustered sole female who barely recognizes the familiar voice calling her Haru. Hesitant kisses melt into devoted cunnilingus and relentless vaginal sex where his big penis stretches her soft, trembling body, her big breasts bouncing and juices flowing as she loses herself in ahegao ecstasy. With age progression leaving her more voluptuous and sensitive to every touch, their fantasy cohabitation becomes a possessive, honeyed spiral of pleasure where returning is the last thing either desires.
