Dean changing the oil in the Impala

Cassie smiled before going over to her husband and his car. "So it's time to change the oil again I see." She told him. "It must be time to change yours too." She told him, which got his attention.

"Like I trust you this week, you haven't once gotten me off the three times you would. You left me to get my own self off which isn't fair." Dean told her before he went back under the car.

"I will do you a favor this time, Dean." Cassie said pulling him back out and getting on top him and the creeper and kissing him as she ground herself against him.

Wrapping his arms around her he kissed her back until he needed air. "Guess I can trust you this time." He told her. "Can't wait to be inside you." He told her reaching up to undo her bikini top, but she pulled away. "Cassie." He almost whined as she did so.

"You tell me when you're close I want to be in you when you cum." She told him.

Dean flipped them over making sure she was still on the creeper as he started kissing his way down to her stomach unfastening her jeans and sliding them off. "You're going commando baby that's hot." He told her before tasting her licking her up and down sucking at her clit every time he came up. "Don't forget to tell me." He told her as he pushed his fingers in stroking her G-spot.

"Dean I'm going to cum." Cassie said and she had thought Dean would play nice this time, but she was mistaken. "DEAN." She yelled at him as he stood up.

"When you're done I'm going to need the creeper back." He informed her. "You see baby you shouldn't have left me in bed when I was cumming this morning." Dean told her before going to the trunk and getting the new oil filter and placing it on the hood. "I'll just wait in the house, I need something to drink anyway." He said going inside.

"I'm going to kill you for this one." Cassie said pulling her jeans back on before she took the oil filter off the hood. "You're going to let me cum this time, because till you do you're not getting this back." She said with a grin before falling him.

Dean went back outside few minutes later and the oil filter he new he'd placed on the hood was gone with a small note that said. "The oil filter you acquirer is laying beside me on the bed come and retrieve it once you get me off 

you can have it." It was signed. "Cassie Winchester, your completely naked and horny wife." Dean was up there in no time.
