When a man sticks his penis in a woman's vagina or a man/woman's mouth.
I ditched school for the second half of the day, I hated all the teachers. Fuck my life. I took a trail in the woods home, when suddenly I was pinned to the ground. I looked up to see Ryan, the hottest boy in my school. His lips kissed mine and started to tongue me, and when He ripped his shirt off to reveal a six pack,I giggled, kissing down his chest as he pulled off my shirt. I wasn't wearing a bra, so he started to suck. Moaning, I started to take his pants off, his boxers sliding down with it. I stared in joy at the 9' cock in front of me, and teased him off, starting to lick the tip, sucking on it. He moaned and screamed "Faster!" So I bobbed my head back and forth, taking about five inches into my mouth with the first thrust, gaining an inch every time. Groaning, I stopped sucking and started to pull my own ants down, where he fingered me hungrily. "Just fuck me already!" And he did so, pulling off my thing and at first teased me with it, before slamming his cock into my vagina, all 9'. Moaned and screamed, and he thrusted faster and faster until we both came and lay on the floor, and we made out again.
