I can't remember what it's called. It revolves around a husband and wife. The husband is an office worker, fairly young adult, but the wife is young as hell. Very cute. In one chapter, they're at a company baseball game type event and she is dressed up as a cheerleader, but isn't wearing any panties. They are never shown having sex explicitly, but there's a lot of mutual masturbation and oral.

I know they have it on animephile. Pic related. Similar character design, but smaller boobs, shorter hair.
