Fairy Tail - Erza Scarlet and Natsu Dragneel. 4-panel.
Title: Pleasure Game
Outfit references provided
1st - Erza on her knees giving him a tit job with a self-satisfied look on her face with Natsu leaning against a tree or stone, straining to keep composure.
2nd - Natsu holding Erza's head by the pigtails as he starts to thrust his hips up, ******* his cock deeper into her mouth. A surprised look on her face as she looks up at him, but she keeps going.
3rd - Natsu jams it in deeper still, cumming *****fully in Erza's mouth, really surprising her and making her eyes roll back a bit. She tries to keep it all in her mouth but some end up spilling from her mouth and onto her tits.
4th - Erza sensually licking some cum from her fingers, while cupping her breast with her other hand and a 'still hungry' look on her face. Have a little cutout of Natsu giving a toothy grin in response.
