I looked up at him, his eyes were shut tight and he head was contorted upward toward the ceiling. His thrusting grew wild and convulsive. They were ...harp little bursts of power that seemed out of his realm of control. Occasionally he would even miss my mouth and bounce of my cheek, but it didn’t phase him. He began pulling back so far that his penis was completely outside of my mouth and then thrusting so hard the entire thing would force its way into my mouth and it would slam my face hard. I stopped and peered through the crack in the door. Fiona was on her knees in front of Stewart.His work shorts and underpants were below his buttocks and he was pumping his erect cock into Fiona's willing mouth. I was agast but spellbound.I felt I should be outraged but instead I was aroused and when Stewart kissed Fiona's mouth while lifting her onto his workbench my cock swelled and hardened.Stewart fumbled with Fiona's panties and pushed his thick cock into her gaping vagina,pumping. "She's in our casa and is excited that I'd stay with her after all the times she's stayed with us." I don't know if Mary and I will sleep together at all on this trip," I said. "We're kind of building up for after graduation." Well, you could call any of the juniors," she laughed. "Have fun, Brian." Doreen, are you upset that we aren't getting married? Mom kind of harped on that a lot last night," I said. I guess it was predictable that she'd want her grandchild to have parents who were married. He asked me to press my boobs on the t. I did what he said facing the cam.He is stroking his dick and am loving it. He asked me to lift the t till my boobs and asked me to press them. Then I removed my t and pressed my boobs together, applied some saliva on both my nipples and teasing him. He is continously stroking his dick. Then I brought my pink 7 inch dildo from under my pillow which he gifted me on my birthday. I put it in my mouth and sucked it uumm umm ummm for nice 5 minutes thinking.
