"Hey! You're spreading my ass cheeks!"
"Yeah, exactly what you think it is!" Dapper replied with a wide grin as he pressed his dick against Lily's tight asshole, easing it in inch by inch before suddenly ramming it in with full force, thanks to the slickness from her mouth earlier.
"ARGH! FUCK!" Lily cried out, her body writhing from the sudden pain. This was her first time being penetrated in that hole, and she had completely underestimated him. He was so quick to take advantage of the opening.
"You jerk! Take it out!" she bellowed.
"And who's the jerk here? You, obviously. Oh, and by the way, keep your voice down unless you want someone to catch you moaning on a student's dick," Dapper said with a mischievous grin.
"I know your secret!"
"And I know yours. Now be quiet and let me use your asshole the way it's meant to be used," Dapper growled, starting to move his waist steadily.
