Amy has bought a new spa tub for her father for his 60th birthday. She wants to watch him try it, to see him enjoy his new gift. Dad thinks that's a little strange, but he agrees as long as he can wear his bathing suit. Funny thing is Amy puts on her bikini as well. Just to watch? Seems she planned on joining him in the tub all along. First she soaps up her hands and jerks his dirty dick. But that doesn't get it clean enough for her liking, so she washes it further with her mouth. Pappy's penis gets so hard from this attention, that he uses it like a scrubbing brush to clean out his daughter's filthy pussy. (The only thing dirtier than her mind is her pussy it would seem.) When daddy gets tired of fucking her (he is 60 after all) he uses his fingers. It takes four to keep her satisfied. In the end he washes her mouth out with his own brand of soft soap.
