Not quite Monica

And right now, he was testing the shit out of his new invention together with his son Tim!

Tim was 26 years old and the oldest son in the family. He lived abroad in a studio apartment a few states away.

That faithful day, what looked like Tim's neighbor Monica posed on the sofa in Tim's dorm.

Monica was Tim's neighbor. She was 25, athletic and attractive. In addition, she had a great ass and tits! Walter had only met the young medical student briefly when she moved in. But she had made it clear to Tim very early on that she had a boyfriend and was therefore not interested in him!

"Mmh, son ... I have to say that being Monica feels good!" came from her in Walter's voice.
"Yes, dad! And looks like we caught her at the right moment!" came from Tim only.
"Hehe, yes! I'm wondering why she dressed herself up like this? Maybe it has to do with her boyfriend?" said the fake Monica calmly as she started to knead her breasts properly.

"It takes a lot of getting used to this thing! But mmh, she has big breasts! Ohh ...".
While she was fiddling with her tits, both suddenly heard in a high-pitched female voice "Oh yes, I'm coming, I'm coming!".
The fake Monica stopped quickly.

"Was that...".
"Yes, that's Monica's voice! And I think now we know why she dressed up like this!" grinned Tim.
Then he had a dirty idea. "Hey dad, don't you wanna walk over to the two looking the way you are? They could surely use a second Monica for a threesome!"
"What!? Son, you pervert!" began the fake Monica.
