My wife and I frequently have s** while sleeping. Typically initiated by me but transforms into full on s**. Last night we had sleep a*** for the first time. She was awake for the start but quickly fell asleep while it went on. I reminded her in the morning that she took a full load in her ass last night. She was shocked that it didn't wake her completely. She has always been worried that it would hurt. Myth Busted.... Maybe her ass a bit too..
