Brother in laws gf (MF)

So one day I go to my in laws house to pick up some tools for a project I’m doing at my house. Now I’m 30 years old and married to they’re daughter who is also my age ..so I get to the house and get the tools, I go to the kitchen where they keep the water bottles and I hear the shower running..now at this point I didn’t think anyone was here but my brother in law and his gf live at my in-laws house. So I go upstairs and I see the door slightly cracked ..I look in my brother in laws room and I see panties on the floor which makes me think it’s his gf showering ..so I try to peek through the door cuz she’s hot, shes 20 smoking body. At one point I pick up the panties and smell them which they smelled real good lol ..so I go back downstairs cuz I don’t want to get caught and wait for her to get out. She comes downstairs right after and gets spooked a bit when she sees me and at this point she has just the towel on..I GET ROCK HARD!! I asked where my brother in law was and she said he went on a hike..so I make my way to the door and she stops me and tells me that she’s horny lol ..I told her with the biggest adrenaline rush going through my head “I can take of that” lol man we started making out ..we went to the couch in the living room and I took my pants off and she starts sucking my dick like she never sucked a dick before ..fast forward I been fingering her the whole time she’s been sucking me off then I go to stick my dick in and I pull it out and the it was covered in grool ..so she tells me to put it in her mouth and she sucks the glaze off my dick..long story short she swallowed my load ..great slut lol
