Susan

"Hey," Susan whispered. "Can we talk?"

I gestured for her to come in and she did, zipping the door closed behind her. That's when I noticed that she was still nude.

"What's up?" I sat up and moved my sleeping bag off me showing that I was still naked as well.

Clearing her throat, she responded. "I'm sorry if we embarrassed you out there. My mom can get a little wild when my dad isn't around."

"I wasn't embarrassed. To be honest, I was very much turned on. You and your mom are both really sexy."

She stared at me. "What are you saying?"

"I'm saying that I would like to have sex with you. And I would like to have sex with your mom."

She glanced down and my fully hard dick for a second. Then she crawled forward and kissed me, straddling me at the same time. Briefly pausing to grab my dick, she lowered herself onto it.

Grabbing hold of her, I moved us both so that I was on top. She matched each of my thrusts as we went harder and faster. After a while, I felt myself getting close to cumming.

"Jake, I'm close."

I just nodded and went faster. With one final thrust, I came deep inside her as she came all over my dick. We then lay there and drifted off to sleep.
