"EROS Survival" is a show broadcast over the internet where pair of players - a male and a female - compete for the grand prize of $1m! To win though the pairs must demonstrate both knowledge and skills in order to 'strip' their opponents, progress through the rounds and grab that super prize!

A boy falls in love with a girl, who is the student council president of their school.

Unable to confess, he is gifted by a deus ex machina when he innocently uses his cell phone camera to spy on her. On one of his playbacks, the boy realizes that the girl is not wearing any underwear.

But, the next day, when he recounts the previous day's events to the girl, she asks him to do her a favor. After some investigation, he finds out that the girl actually has a repressed exhibitionism fetish — She secretly wants to experience the thrill of showing her naked body to the world, but at the same time doesn’t want anyone besides the boy to know.

Hijinks ensue as the two strike up a deal to give each other their most desired fetish scenarios, but DRAMA ensues as they begin to fall in love with each other instead and question the NATURE of GETTING NAKED AND HAVING A GUY FILM YOU IN A PUBLIC AREA.

Description from Triple Seven Scans.
Since his childhood Tamaki has had a medical condition; he gets the hives every time he has skin contact with a girl. One day his sister sends him a life-sized doll so he can use it to masturbate, to his surprise it's alive...and it looks exactly like his favorite eroge heroine, Lemon-chan!

Hired for an eviction of an apartment resident, lawyer Midorikawa visited a mysterious apartment. Since the visit, he has been haunted by these visions of "Angels," small naked girls who have faces that of a doll.

Are they part of a horrific dream? Through Midorikawa's body, they escape the infected apartment. Now, they spread their horrors upon the city!

Includes an unrelated short story called Daijoubu! Koi x Koi (All Safe! Love x Love):

But no amount of simulated warfare could have prepared him for what is to come… Ryouta wakes one evening to find himself dangling from a tree by a parachute with no recollection of how he got there. Before he can orient himself to his unfamiliar surroundings, Ryouta is attacked. As a barrage of explosives rain down on him, Ryouta realizes that he too has a pack of bombs…bombs that look very similar to the ones used in BTOOOM! Ryouta may have mastered the online game, but can he come out on top in this real-life game of survival?

Yoshida ♂ and Dobashi ♀ are the only students at a branch school in the countryside. Later they are joined a third student, Kobayashi ♀.

The beautiful, talented girl who just beat me to become Student Council President, suddenly shows up at my house announcing that we're getting married, because of an old promise between our parents? "No problem, if I just harass her for a bit she'd surely run off" I thought, but she might just be a bit more formidable than I expected.

Like, Excalibur, this Cecelia needs to be pulled out of something... a pedestal. For Seiken-chan, the pedestal is her panties.
