I feel bad for always asking for help. I'm sorry! But here goes, if I remember the yaoi I'm looking for is about the uke who sees his senpai making out with the captain of a team jn the sports storage room. He witnesses them having sex which cause him to get erect and relieve himself on the spot. He then felt embarrassed and quickly left to his dorm room. After he felt curios as to how it will feel to have something in him so he begins to try it himself. Then one day his senpai came into his room while he was doing it to himself. His senpai then tells him to come by to his room to try out the toys that he has. Then lots happened and they ended up together. Please advise! Always thank you and greatful for your help!
