Redoing The First Time With My Beloved Senpai

From Tonpuuratei's series of original doujins, this time featuring the shortstack senpai Arisa and the tall kouhai Haruyuki, who as lovers, recently had their first time under the influence of alcohol.

That said, she was so drunk that night that the morning after, Arisa could not remember what happened; and without memories of their long-awaited first time, she worried that their first experience was ruined and possibly a failure. Haruyuki, with his girlfriend's feelings in mind, makes the suggestion that they redo their "first time". The two of them head to a hotel to try and have a lovey-dovey second take of their "first time" experience!
