Maybe not so NSFW

Starters that are a little dirty but could be completely innocent:
“That’s pretty big…”
“Push it in.”
“You had better wrap that.”
“Room for one more?”
“Oh, that’s nice.”
“Harder. HARDER I said!”
“Put this blindfold on. I have something to show you.”
“I’ve never done something like this before.”
“Isn’t that a little awkward?”
“I need it. Give it to me.”
“Get in bed.”
“I bought something today. Want to see it?”
“It’s just you and me tonight. I was thinking we could have a little fun…”
“Want to play a game?”
“Turn over.”
“I’ve got something for you.”
“It was enormous!”
“I’m exhausted.”
“I got some whipped cream and chocolate sauce…”
“I’m hot.”
“Please tell me you brought protection.”
“I like coming in through the back door.”
“Fine. Just keep quiet. I don’t want anyone to hear us.”
