Shocked!

Issei stared at Rias with a shocked expression. His mouth was gaping like a fish.

"I-Im your servant?" He asked Rias with a stutter. Rias just chuckled and explained to him what it means to become a servant of the Gremory Household.

Issei however was not paying ettention to her and instead was staring at her huge breasts concealed in a tight school uniform.

Her breasts were just begging to be sucked. He could imagine sucking those huge funbags. Those rosy nipples that he imagined she had. Ohh god he could just feel it.

"Issei? Earth to Issei," said Rias as she finally realized that he was not paying attention to her.

"Uhh what were you saying?" He asked her. Rias repeated everything she said before with a slightly faster tone.

"So bassicaly Im a Devil and a servant of your house. Im supposed to help you destroy rogue Devils." He said.

"Spot on Issei," she said to him. Whilst she said it, she was leaning forward and showing him her genorous clevege.

His pants became too tight and his cock was becoming harder by the minute.

So he did the most logical thing in the world. He groped Rias Gremorys breast.
