My mother in law said the same thing when I sprung my hard on at her! "Look at that Whopper!" She also said "I don't know if I can fit this thing in my mouth, but here we go!". It took a lot of convincing, but she finally said "It looks like we are gonna have to put in the rear!" She was just too tiny to take a big knobbed Sicilian cock in her pussy. With the little apple bottom she had, I already had sights on her perfect donut ring. Hearing her moan and say "I'm-ah Cumming" while I ravaged her asshole made me cum, immediately. Best sex, ever. She got an incredible load out of me, it was everywhere!
My wife works as a sales representative and travels a lot. We live with my mother-in-law, who has been divorced for several years. A few months ago, I slept with my mother-in-law, and since then we've had sex regularly. Even though she's almost thirty years older than me, the sex with her is incredible.
