Seiso na Bakunyuu Hitozuma o Beach de Dekachin Namahame ~Teisoukan no Tsuyoi Mesu o Nanpa Soku Pako de Haramase Onaho Netori Suru Natsu~

Our hero heads to the beach to pick up some girls, and one in particular catches his eye --
busty and full-figured housewife Kana Misaki! She tries to get away, but the less popular spots
are also the best places to have sex! And as things start to heat up, she gets more and more
into it... And thanks to the wonders of technology, a smartphone video ensures that he can call
her up whenever he wants for some fun she can't refuse!

It's gonna be the best summer EVER!
