Hiroto screamed inwardly as he felt the mistress HARD PEG go into his anus, balls deep. The silicone strap-on felt like a razor-sharp saw in his butthole, and the mistress giggled in delight as his hold slurped back and forth with every powerful stroke. His face still burned from the facestanding he got earlier, and of course, the salty pee that the mistress shot directly into his mouth. With his hand bound and stripped to his underwear, he could do little but to accept the salty piss wholeheartedly. He took his time in swirling the piss in his mouth, before swallowing it. Like whisky, it burned his throat the first time, but not in the second and third helpings.
