BIG TIME sex on the couch. Whatever music they're playing in the background has Maya turned on. She's on a music drug
Edit: Game over: Maya wins 3 to 1 (yea, she was really into it).
Edit 2: After 30 minutes (and a dog walk), they're at it again. Maya initiated with foreplay (don't see foreplay much from them anymore). Now hot-n-heavy (again) on the sofa/bed. Looks like they are watching porn (and for some reason, a hunch tells me they're watching what they self-recorded during a previous romp).
