Whenever a new manga volume comes out, childhood friend Rena lounges around his home reading it, carelessly flashing her panties. The sight is too much for the virgin otaku, who finally gives in and penetrates her. He treats her pussy as payment for every comic he lends her, pounding on without stopping even after he cums. Lazy handjobs and blowjobs lead to doggy-style sex, and they even fuck in the elevator. After emptying three boxes of condoms, another glimpse of her pussy outline through cotton panties gets him hard again, ending in relentless sex and 15 ejaculations captured from every panty-flash angle.
