Mmm I liked it so much that it showed how this blackmail began, and these changes in her face as soon as they took out the cock, she seemed to get drunk from the smell with each picture.
The lines of the Tan look so vulgar, I really love this contrast between the tanned and white skin of the girls.
139 is so funny and cute. Judging by the rest of the final drawings, this blackmail will continue further, but with changed circumstances and desires of both parties.
Now Nagatoro will be blackmailed with cocks, if she is disobedient she will not get this desired candy
