Friend asleep on call but I'm horny

My friend likes to call me when she sleeps or takes naps and normally it's chill and I don't mind, but I've been really horny for a while now and was literally about to start stroking my cock right before she called 😩

Now I don't know what to do. Part of me doesn't care and wants to just keep stroking, but what if I can't keep quiet? what if she hears my moans and wakes up? that would be pretty embarrassing 🥴
