A set of lingerie and sinful sex

The guy was away and his girlfriend, a total hottie, had to deal with his parents who came around to visit. Well, look at her, is there any way she could have dressed skimpier? To make things worse, the guy's mom and dad came around with a gift for her. Yay, a set of lingerie! One has still to find out where trying the lingerie on evolved into a threesome. At some point definitely! Both the old man and his wife were horny to the point of no return, and they literally pushed their son's girlfriend between them into a sinful sexual sandwich. Ouch! The guy came and it was quite a bit of a disaster...
