Calling all ecchi experts!

The manga is centered around a "chaste" school girl that continuously misunderstands a scary- but kind- delinquent by thinking he's going to rape her. She avoids this nonexistent assault by satisfying him with all sorts of wacky "fake sex" tactics involving puppets, vacuums, and a myriad of creative faux-vaginas to preserve her chastity.

I read all the available chapters a few years ago and really enjoyed it! I'd like to continue the (hopefully completed) series, but alas, I forgot the title.

Any ideas?

Thanks!☆

Most likely Bousou Shojo.
