You knocked and walked in, smiling at me. I looked at you and felt like you’d socked me in the gut. Suddenly everything made sense to me. The way I ...couldn’t wait to get to class, the way my heart clenched every time I spent more than a second next to you, inhaling your perfume, listening to your voice. The way my hands trembled from the need to touch you and to hold you so close to me that you couldn’t help but know how much I wanted you. The way my mouth watered to kiss your face, to get. “Do you like marshmallows in your coco?” he yelled from the kitchen.“Yes please,” I replied. “It’ll be ready in a second,” he said.About a minute later he walked back into the family room. He wasn’t carrying a cup of coco; instead he was naked and had three marshmallows sitting on his hard cock. He held it carefully to make sure they didn’t fall off of his 7-inch cock. He walked up right to me, I opened my mouth and he slowly slid his cock in it.“Make sure you get all the marshmallows,” he. After several minutes of sucking at her tits, he drew back and looked at her again, then leaned forward and told her to take the rest of her clothes off as well. She stood and unbuckled her jeans, kicked off her sneakers and drew her jeans down, revealing her white cotton panties. He stared at her ass globes as she bent to pull her jeans off and again as her panties were rolled off and he saw her curly pubic hair as she bent forward again. Her pubic hair was blacker than the hair on her head. As she walked up to me, she moved her hands down, and I felt her hands near my waist. She untied the string holding my swim trunks on, and, gently, I felt her tug on them. I looked over her shoulder, as I felt my swim trunks sliding down my thighs.I stood there, my dick standing straight out, massively erect. I didn't move. Katie moved up against me, pushed against me, and said, softly, "I want to have sex with you."I had never done anything like this before in my life. I had never crossed that.
