Drinking with Millie and Patti

We are sitting on two sofas, Millie and myself on one, and Patti sits across from us. The wine is flowing pretty freely, and after a while I excuse myself to go to the bathroom.

When I return, only Millie is there. I sit down, slide my hand under Millie's dress, and rub on one of her big tits.

"Need to take advantage of being alone with you finally" I whisper to Millie. Millie laughs and throws her head back, and I keep playing with her big tits. A minute passes, then another, and I ask Millie:

"Did Patti go home?"

"No, she was feeling a bit down, so went to her room." Millie replies, then continues:

"Actually, why don't you go check on her?"

"Emmm... I guess I could, but is it not better if you go?" I ask.

"I am fine here." Millie replies, and nonchalantly has a sip of her wine.
