You are sleeping at your girlfriend, Mia's house for the night

When you wake up, you see somone else in the bed, a third person. It's Mia's mom, and she is looking at you

Mia's Mom: "Hey there, sweetie. I was feeling little cold."

She snuggles up to you and smirks

Mia's mom: "Mmh, so warm..."

Mia's mom caresses your chest

You notice that Mia is still sleeping
