Summer is here, and with it Comiket! Matsukawa and his harem of succubi take a trip to Tokyo so the girls can show off their cosplay. Before that though comes an all night succubus fuck fest at the hotel, complete with sling bikinis, cat keyhole bras, and sex videos! And to top off their trip, the succubi are of course yearning to have sex in their cosplay outfits, especially after getting all excited from being hit on by men all day! Matsukawa needs not to worry though, for these three girls are loyal only to him.
