Every now and then Tsuyu needs more than just jerking off her cock. And when nobody is around to give her a good filling, she can always use her tongue. Luckily for her, her tongue has gotten quite a bit thicker since she turned into a futa :3
I don't often draw or indicate the girls' female parts down there, but to me it's actually important that they have both. I want to show it a bit more often, but it's difficult to do sometimes, as I'm usually happy with only their dicks on display ^^'
I hope you like it and have a great start into the next week!
