College couples enjoying a romantic kiss at the paramours point

A not many college couples are enjoying a romantic kiss at the paramours' point. Its' just after college hours and so they come here for some romance. One of their allies is still single and is feeling a bit jealous, and so this chab starts to tease 'em by making a video. But this chab hardly bothers them, they are on fire and are not going to let anyone disturb 'em. Though one of the couples is a bit shy and one other chap is trying to hide his face. I wonder why.
