ボケたじぃちゃんを心配して田舎の家まで様子を見に行くと…そこは家出ギャルの溜まり場に！？これは一大事だと思ったら胸チラ＆パンチラを見せつけられてじぃちゃんはご満悦！こんなの羨まし…いや許せない！なんとか寄生ギャルたちを追い出そうとしたけど、逆に標的にされるボクのチ○ポ！じいちゃんより元気な若チ○ポということで、ギャルたちは一気にヒートアップ！エロ過ぎる攻撃に抵抗むなしく撃沈し喰われまくるボク…。じいちゃんゴメン！この環境最高だわ！そして数々のナイスアシストありがとう！

Worried about my senile grandpa, I went to check on him at his house in the countryside… only to find it a hangout for runaway girls!? I thought this was a serious problem, but then I saw the girls flashing their cleavage and panties and my grandpa seemed delighted! I'm jealous… no, I can't stand it! I tried to chase the parasitic girls away, but instead, my dick became their target! My young dick is more energetic than my grandpa's, so the girls got really excited! I was no match for their overly erotic attacks and was defeated and devoured… Sorry, grandpa! This environment is the best! And thanks for all the great assists!
