[Marneko] The Girl Lottery (Nyotaika Happiness! 2) [ChoriScans]

A reluctant lottery winner named Satoshi draws the short straw and must take on a curvy, dark-skinned feminine form, setting up a messy chain of intimacy among a group of high school classmates. As the others ogle his new busty body and tight outfit, Satoshi is quickly overwhelmed by teasing hands and escalating "rules," with claims of "usual rules" flying between participants and Satoshi protesting that the poor guy never thought he'd be "speared by" his friend first. By the time a jealous onlooker shoves a dildo into the new girl's mouth, the once-awkward loser finds himself moaning in a tangled pile, unable to back out of the cursed Girl Lottery.
