Serene Siren guides Leana Lovings into her private lab, the girl’s steps small and obedient. Serene intends to prove a single filthy idea: steady stimulation and the right dose of futa seed might make a cock grow where only a cunt once waited. She seats Leana over the custom saddle, nudges the soaked panties aside, and lowers her onto the thick, already-gleaming dildo. When the motor starts, the shaft pulses, deeper, slower, then faster again. Leana’s breath hitches; her slick walls clutch at the toy, and beads of milk begin to pearl at her nipples. Watching those drops form, Serene’s own length stiffens beneath her coat. She steps close, pulls the girl’s mouth to her cock, and Leana opens without hesitation. Serene rocks her hips in short, controlled thrusts until she floods Leana’s tongue with hot, thick cum. The moment Leana swallows, a throb surges between her thighs. A new shaft presses outward, swelling, rising. Leana wraps her fingers around it, already stroking in wonder as it hardens. Serene watches with clinical delight, then climbs onto the saddle behind her. Two glistening cocks find slick, eager holes; the machine’s relentless rhythm takes them both. Science, they learn, can be exquisitely persuasive.
