That dildo excites the dude more than her. He probably has already taken a cock up inside him and knows how good it is, and now is getting aroused seeing another cock, bigger than his, fucking his girl. I know, I feel the same
Would love to pull her ponytailed hair while buried up her ass, balls deep, I'd make sure she felt every inch of my length embedded inside her awesome shitbox. I bet she has a hole made for abusing and I'm just the man for that job!
