Sportsman's Double

21 year old guy goes into a bar, sees a really hot chick, so he sits next to her and they get talking. Well, it turns out she's 65. But doesn't look it, looks more like 40ish. So he's like oh well fuck it! Then she asks him "Have you ever had a sportsman's double?" "What's that?" "You know, mom and daughter 3some!" "No." "Well, how about it, wanna come back to my place?" "Sure!" He's thinking ok, if the mom is 65 and looks this hot, then the daughter must be 30-40-something and look even YOUNGER! They get back to her place and the 65 year old woman yells upstairs "MOM, WE'RE HOME!"
