It really wasn't quite the night that Seamus figured that Dean was going to plan for them. He was honestly thinking that somehow prostitutes would be involved, but was sort of relieved when he found out there wouldn't be any.
Prostitutes led to undercover arrests. Arrests led to Severus Snape firing Seamus before he even started.
A massage and an explicit art show was different, but as the really fit bird ran her hands up and down Seamus's legs, he could pretty much care less about the world around him.
"Uggmmhhh" he groaned into the table, then turned his head to the side to grin at Dean. "You have no idea how long I've needed this. My body tends to tense up from...you know...running around," he stammered at finding the right words, remembering they were in muggle establishments.
