I absolutely love this idea, but I think it would be better to show more of the progression from the initial bliss to the current withered prunes spitting dust. You don't need to give her hyottoko lips or make 4/5ths of the comic blowjobs like Fellatrix's "My Shy Girlfriend is a Blowjob Expert?", but maybe just some panels showing his first impressions, followed by him starting to get overwhelmed by the affection, followed by him trying to keep up (drinking more or taking zinc supplements or something), followed by his brief reluctance as he realizes he just can't keep up, and ending with his acceptance stage.
