if this were hentai logic he would have realized what they were doing, joined the fun, creampied her into orgasming nirvana with the sluttiest ahegao face she could muster before she passes out with the lot of them. Then fucked some more in the AM six more times and two gallons of cum later. This is just idiocy at its finest; see you later space cowboy~

Still, I found it interesting that he bought the ruse that she was a poster, especially when he woke up sober and saw her posing with some obvious white stuff sticking off her.
