looking for a manga pt 2

while reading a different manga i thought of another manga i would like to read

I REMEMBERED MORE

what i remember is that the seme had glasses but he was taking his time getting the uke prepared because he didnt want to hurt him, and this was the only thing the seme would do over the period is weeks. after some time the uke got frustrated and started to use a toy on himself and then the seme got home from work and saw and i think he got jealous

the seme had lighter hair (it was in black and white) and the uke had dark hair and had muscles
i also remember the seme refusing to have anal sex because he saw somewhere that you shouldnt do anal till the uke can climax with just his ass being played with, so thats what he did. prepared the uke till he climaxed with just that, but the uke got frustrated and almost used a toy but then the seme got home from work and thought the seme was mad and apologised. but then so on and so forth they ended up playing around and the uke climaxed from just his ass being played with

anyways help if you can please
