She's good with that.

Alison knew what her son was doing upstairs with his girlfriend.

She new it was only natural for them to be curious and want to find out what sex was like for the other partner.

But she could not stop herself from walking in on her son and his girlfriend making out against the wardrobe and ask them.

You guys need anything?

Some snacks?

A condom?

But she was surprised by how much her son was enjoying being in his girlfriend's body and taking what she was most vigorously giving him as they both shouted in unison for her to fuck off.
