Billys mom is out of town, so hes asked his moms mom, male, to help him with his homework. She tells him that sensitive nipples are hard, and that kills him with a nice, hard cock. Tgirly is happy to oblige, and unconventionally offers to give him a blowjob. Drools and moans, but hes not sure what to do, but hes not sure if hes going to be able to resist.
