As many as possible.

You walk over to the pair, and situate yourself directly behind the nymph, who is crouching on all fours over Venus. The nymph’s sheer tunic has slid off of her now-bare ass and down her back to rest just below her unbelievably perky breasts. You reach towards the nymph’s butt, grasping one firm cheek in your right hand and squeezing gently.

As she withdraws from a deep kiss with the love goddess a thick rope of cum stretches between their tongues, breaking finally as the nymph moves back down towards Venus’ chest. The motion arches the nymph’s back even more and push her tunic up above her breasts, which slide along the goddess’ taut stomach. It also rocks the still-kneeling nymph’s hips upward, pushing her firm ass back against your hand and separating her cheeks even more.

Your thick cock is now straining forwards towards the nymph’s smooth damp pussy. Down past your massive cock, Venus’ hips are moving slowly. As the nymph sucks and then bites gently on her nipples the goddess gyrates her wet hole against your knee. Still holding the nymph’s ass in one hand, you maneuver your rock hard cock towards her glistening vagina. As the head of your cock enters her tight opening she lets out a soft scream against Venus’ breast. As the nymph’s teeth inadvertently tighten on her nipple the goddess lets out her own gasp and grinds her own pussy hard against your leg. You halt your entry, and withdraw slowly.

“Why stop…?” The nymph looks back breathlessly over her shoulder at you. Still grasping her firm butt with your right hand, you run the fingers of your left over her sodden pussy, pausing to sink your thumb into her slick hole.

“Mmmm… better…” says the nymph with her eyes half closed. You withdraw your thumb, and she looks at you pleadingly. You run your thumb upwards, and trace a moist trail around her tight little asshole. She starts panting in anticipation, and you sink your thumb slowly into her sensitive hole.

“Ohh… Fuck yeah…” she moans. Her pussy is dripping now, it’s slick wetness running down the insides of her thighs as you work the base of your thumb against her anus.

“…. Fuck!!!” she screams suddenly as you sink half of your cock back into her pussy. A convulsion rushes through her entire body. The lithe nymph arches as much as she can, and her asshole clamps down even more tightly around your finger.

You can feel your own cock against your thumb through the thin wall of skin separating her pussy and ass. Her pussy is straining to accept the width of your cock, and the area of smooth skin surrounding her pussy is stretching to accommodate, as well. Amazingly, just above your thick shaft even her anus is stretching sideways slightly. You start pumping your engorged member into the nymph slowly, causing her to let out a strained moan of pleasure with each thrust.
