これ『を』買いたい（ん）です

If you're pointing, however, that likely means the object (or futanari doujinshi, in your case) is closer to the listener, in which case you'll want to switch to それ. In any case, being as descriptive as possible is always the best option but if you can't handle anything outside of demonstratives, that'll do. If you'd like to be more a little polite:  これを買いたいんですが・・・

失礼ですが、（おつり）を二度と確かめなくてもいいです。
Sorry, but you don't need to confirm the change a second time
