Tell the truth

You decide to tell him the truth, you were a really bad liar and both of your parents were always able to tell when you were lying to them anyway.

"Honestly, I don't know." You say.

"You don't know if you and your boyfriend have had sex?" He asks.

"It's not like that! We went to that party, and we were both a little drunk and went up to a bedroom together."

"Oh." Your Dad says, shifting on the bed. You can tell this talk is making him grow increasingly uncomfortable, but you need to get it off of your chest.

"We were making out and...groping each other," you see his hands fold in his lap, "and it was getting pretty hot and heavy I guess, but it just didn't feel right. So I stopped him and we came home."

"And had phone sex with the door open." He smiles at you and you can't help but laugh. You both laugh for a while and eventually, you rest your head on his shoulder, both of you wiping the tears from your eyes. He puts his arm around your shoulder and starts tracing circles into your upper arm. You look down, and see a pretty obvious twitch in his pants. Was he getting an erection?
