Step-Mom's 21st Birthday Surprise Quicky

It's my 21st birthday and I've gone on a camping trip with my family. The rest of the family is doing there own thing, so step-mom and I decide to go on a hike. She said she has something special for me. The only thing is that we have to be quick and quiet about it. What's this, she is going down on me for a blowjob right in the outdoors. Dam this feels good. Getting some good head from step-mom out in public. Oh yea, she is going to let me put it in her. Fuck, we have to hurry up. I have the perfect idea... I'm gonna give step-mommy a facial in return as a way of thanking her for this great birthday surprise.
