My 18 yr old girlfriend is too fuckin lazy

I've been fucking with this younger chick lately, she only 18. She swears she knows it all but the problem is she's lazy as hell! Bitch doesn't cook or clean or anything she just sits on her phone on the couch all day. Today I told that good for nothing bitch to get the fuck out. Finally she reminded me what she was good for. These 18yr olds have way tighter pussies and the get so wet. It felt so good to cum inside that fresh 18 year old pussy.
