You felt bad for Mark showing you alot of pleasure all the time you decided today was the day you repay him, yeah you would give him blowjobs every now and then but you wanted to do something special for him. When you and Mark walked into the bedroom you gave him some instructions, you watched as Mark got on the bed pulling his jeans and boxers off then he layed on his stomach, you made your way over to the older male and felt his ass. A slight yelp escaped Mark, you smirked and gently slapped his right cheek, Mark moaned softly "oh does Marky have a kink?~" you teased "sh-shut up..." Mark mumbled "alright then I'll stop" you moved your hand away "NO!" the older male exclaimed "p-please hit me again..." You smiled and slapped Mark's butt cheek again.
Mark bit his lip as you pulled your belt off, then you jeans and slipped your boxers off, you slapped Mark's left cheek and pushed your tip against his hole, Mark flinched then nodded you slowly pushed inside.
