Cuddle Boyfriend's Sex Therapy summary:

"Shunichi Izumi is an office worker who became somewhat sleep deprived because his boyfriend dumped him. During one of his sleepless nights, he comes across a rental boyfriend service that specializes in cuddling to help sleep! Wanting to sleep no matter what, he makes an order while drunk, causing a shallow-looking guy named Ren to show up. Plus, the cuddling was way more close-contact than he expected!! Getting held in Ren's muscular arms makes Izumi to react down there... On top of that, Ren asks if he wants help, and uses his large hands to make him c** in no time...!!"
