Karadagoto Tabete Yaru - Ueta Ookami wa Dekasugiru!

Official English: INKR

"Himari, you're so light, it feels like you'll break..." "You're so deep...! Don't thrust so much..." Himari's entire body is completely wrapped around by a younger man whose size is twice her own. When Himari, who works as cafeteria staff at a university, is buried under the passengers of a cram-packed bus, she's saved by a tall student who lifts her body up. She bumps into him again during a late-night bus ride, and the two of them accidentally oversleep all the way to the last stop. There, the day comes to an end. The young man suggests staying at a love hotel and Himari is forced to spend her night there...!? On top of that, he tells her, "Since you don't have a boyfriend, it's fine. I'm pretty good, you know?" and suddenly Himari finds herself lifted from the ground, dangling, then pressed into bed! His long fingers reaching deep inside her, Himari becomes thirsty for more. D-don't put a cock that huge in me! I'll break...!!!
