He woke up.

The sisters stood over their brother-in-law waiting for him to wake up from his latest fainting.

"Oh, you woke up! Onii-chan, are you alright?" Yuika asked when he woke up a few seconds later.

He nodded.

"I am glad. Maybe it was a side effect of the medication," Mari wondered, looking at his still hard cock.

"Do you think he can still cum?" Yuika asked, looking at his erection.

"I am sure he can," Mari answered as she placed a finger on the tip of his cock and moved it around like a joystick. "Look, it is still so hard!"

"I want to stick your cock inside me again!" Yuika begged.

"I cannot hold myself back anymore," Mari pleaded while she slowly stroked his erection.
