My wife’s mom was married at an early age. My father-in-law was 30 years old when they got married. I had never looked at my MIL in a sexual manner ...till this incident happened.Even though she was 54 years old, she looked like she was in her early 40s and looked sexy with big assets – both in the front and at the back.During dinner, I watched my MIL a few times and started to admire her. She also looked at me a couple of times from the corner of her eyes and smiled.I started to develop sexual. Her face was glowing in that heat. She drew the zipper all the way down. Jake wore no underwear.His prick leaped out like a frenzied bull rushing into the corrida, looking for warm flesh to gore. Marion gave a little gasp when she saw how big and hard his cock was. It was not a horse cock, to be sure, but it was a plenty big enough human prick. A dark, thick vein pulsed and fluttered up the underside of his fuckshaft, his balls were bloated with cum and his cockhead flared out like a hooded. Already the tip is dripping wet enough that I run my palm over it and slide it down my length enough to lubricate it completely. It feels good, I could cum now but I need to take it slow, stay sharp, and keep my eyes open. I don't want to get caught or miss an opportunity to find another of my people. Still nothing, I'll have to amp it up. I wrap my fist around the base and run it up to the swollen head forcing more of the slippery fluid from it. I focus on the tip where I'm most sensitive in. Ah fuck, I gasped Harder, harder! I arched my back feeling the familiar tingle rising in my inner thighs. No problem. He grinned and humped. God! Im gonna fucking cum! he yelled while picking up the pace. Me too! I gasped. Ahhhh shhiiiittttt!! we screamed as we simultaneously came. I felt the spurts of cum splash on his shorts, but since he was so close to me, it felt as if his cum was going inside me. I collapsed on his chest as the waves of my orgasm subsided. We lay there gasping for air. I.
