Kirari Momobami, wearing a strap-on and lays on the back, gives Yumeko Jabami (she also wears a strap-on) a paizuri while Kirari licks the tip of the strap-on (like on the reference image). And Yumeko gives Kirari a buttjob, like on the reference image.
Both should be fully naked, have big boobs and horny expressions.
