While Sister Sleeps

John is fast asleep in bed with his wife when his naughty sister in law creeps in and wakes him up. As his wifes horny sister kisses his neck and jerks his cock he tries to tell her to stop. She just tells him to be quiet and puts his dick in her mouth while the wife is asleep a few feet away! She sucks his cock, kisses his balls and lets him feel her ass until he cant control himself any more and shoots a big load all over himself as his wife sleeps oblivious of it all!
