Skinny and passionate: my sister-in-law's intense orgasm

My sister-in-law is a hot, curvy beauty with a round, delicious ass that\'s always begging for attention. When she\'s feeling particularly horny, she comes to me, asking for a little help in getting herself off. I\'m more than happy to oblige, using my skilled hands and tongue to drive her wild until she\'s screaming with pleasure.
