The two women had him cornered against the picnic table in the empty park clearing, the sun still high enough to light everything up. "On your knees, Mark," Lisa said, her voice flat and commanding. She grabbed his hair and shoved him down hard onto the grass. "You lost the bet. Time to pay up."
Mark's face burned. "Come on, this is fucked up. I didn't think you meant—"
"Shut up," Rachel cut in. She stood behind him, one boot pressing between his shoulder blades to keep him low. "You said anything. We heard you. Now open that mouth and suck his cock like you promised."
The other guy, some stranger they'd pulled from the trail, stood there with his pants already open, cock half-hard and hanging out. He looked nervous but didn't move away. Lisa yanked Mark's head forward until his lips brushed the tip. "Suck it. Right here where anyone could walk by. We want to watch."
Mark tried to pull back, but Rachel's boot pressed harder. "Do it or we tell everyone what a lying bitch you are." Her hand reached down and wrapped around the stranger's shaft, stroking it a few times until it stiffened fully. Then she slapped it against Mark's cheek. "Open."
He hesitated one second too long. Lisa pinched his nose shut and forced two fingers into his mouth, prying it wide. The stranger stepped closer, and Rachel guided the head between Mark's lips.

"That's it. Suck. Use your tongue."
The taste hit him first—salt and skin. Mark gagged as the cock pushed deeper, but the women didn't let up. Lisa held his head steady while Rachel stroked the base, making sure every inch disappeared. "Look at you," Lisa laughed. "Forced to suck dick outside like a cheap whore. Bet you never thought your mouth would be full of cock in public."
Mark's eyes watered. The stranger started thrusting, hips snapping forward while the women kept him pinned. Rachel leaned down close to his ear. "Swallow it when he comes. We want to see your throat work." She reached under him and grabbed his own cock through his jeans, squeezing. "You're hard. Don't lie. You like being made to do this."
The stranger groaned and pushed all the way in, balls against Mark's chin. Hot spurts flooded his mouth. Lisa didn't release his head until he swallowed every drop, gagging and choking on it. When they finally let go, Mark stayed on his knees, spit and come dripping down his chin, the open air cool on his flushed skin.
Rachel smirked. "Good boy. Now lick him clean. We're not done watching yet."
