Role-playing in costumes reminded me of the time of the Indians, the cowboys. It both relaxed and excited the couple. The guy brought the girl into the house in his arms, and she lowered herself down and began to give a skillful blowjob with her capacious mouth. The girl had to do it again after being fucked in her arms, spreading her legs. Sex on the couch succeeded after staging.
And the nerd turned out to be quite good! I thought he was so thoroughly licking her asshole. Turns out he's an anal gourmet. He's been shoving it all the way up her asshole. Apparently this wasn't the first time the lovers had tried it - the bitch didn't even twitch when he came in. She's got an asshole that's big enough for this thing. I'd spank her buttocks to make her swing better. He'd do the right thing with his mouth. Let her get used to being a slut.
More spanking his crotch in the ass, the girl seems to like this kind of fun, just the level of the hole changes.
