Passionate and intense anal sex in the missionary position. Amidst the vigorous thrusting, the bottom's penis sways: the top grips the bottom's hair to support his head while thrusting his hips back and forth violently. The top rotates his hips in wide, rapid circles while thrusting his cock in smoothly and at high speed. The top's cock slides all the way to the base into the bottom's anus, fucking him roughly and intensely. The bottom's penis remains fully erect throughout, eventually ejaculating and spraying semen after three seconds. The top ejaculates inside the bottom two seconds later: the semen then drips from the bottom's anus. The entire bodies of both the top and bottom—from the groin upwards—must remain fully visible on screen at all times. Smooth movements, wide and powerful thrusts, rhythmic piston-like action, smooth full-depth insertion and withdrawal, long and deep strokes, intense sex: the bottom ejaculates repeatedly, spraying semen, while the top maintains complete control. , both top and bottom have muscular, sturdy legs and thighs, no camera movement or zooming.
