At the end of the year, when it was supposed to be a fun family get-together, something unbelievable happened to me... My sister-in-law was an incredibly lustful woman waiting for me at my wife's parents' house. She tempted me with her lewd body, but I somehow refused, and the crisis was fleeting! My reason, which was shaken by her bold display of sex, collapsed in an instant! In the end, I ended up having an immoral creampie session right next to my beloved wife as she slept!
