Possible Threesome

I told my gf how mom saw her saw her sucking my cock,she was shocked at first until I said mom was playing with her pussy after she left I told her how I watched and jacked off as she had left me with a hard on how mom was just looking at my cock staring and rubbing her pussy faster. After I came I went down and licked her wet pussy she asked if I did the same to you.
After mom came spurting loads of cum, I asked if she had ever been with a woman, she admitted yes they had been very intimate for several months until she and her husband moved away. The gf didn't get mad she just asked if mom's pussy tasted good I told her sure very good why do you want to taste it, she hesitated then said maybe, I have not tasted pussy in a long time.
That really turned me on I pulled down her panties lifted her skirt over her arse bent her over onto the bed, her pussy lips were swollen I knew she was turned on talking about eating mom's pussy. I slid my hard cock deep inside her and fucked her silly making her cum then shot my cum over her arse crack. I told my gf we would take mom out for dinner and wine it makes her mellow and very touchy we could even have a threesome maybe, she said maybe if I'm wet enough.
I said if not I would love to watch you make out with each other, she likes you says you have a nice body.
Here goes nothing and hoping for two pussy in one bed on one cock
