【omelette】Night crawling to my mom mistaking her for my girlfriend1

Kensaku invited his girlfriend Saki to his house for sex, but when he got home, his mom was there, so he decided against sex.
When the three of them are having dinner, it starts to rain, so Mom forces Saki to stay over and join them for dinner.
A few hours later, Mom is drunk. I supported Kensaku to sleep on the couch in the living room and Saki to sleep on Kensaku’s bed, and then I headed to the bedroom with Saki.
Kensaku waited for her to fall asleep and went to crawl in the night to Saki, who was supposed to be sleeping in her room, but it was Mom who was sleeping there.
