Up the bum.

"If this was another time, I'd happily give my Mistress' child a playmate," Nanny Mara coos, almost morosely. Biting her lower lip at you, she reaches under herself and spreads her ass cheeks wide, her brown star winking at you. "But not tonight. Come to me..."

Swallowing a dry throat, you scoop up her juices with your fingers and coat her opening thoroughly, before doing the same to your cock. You grunt in immeasurable pleasure, just from piercing through her entrance. Snarling through clenched teeth, you power through her tightness, almost hauling yourself forwards by your arms, with your knuckles turning white on her hips.

A throaty groan joins a sensual sigh when your hips finally meet. "Mmm... yes..." Nanny Mara hisses, creeping her feet closer together, making her muscles close even tighter against you. Your back gives out and you fall forwards, your head landing just under her ribs. Every time your cock throbs inside her, she squeezes back even harder, making it almost impossible for you to move. Taking your hands off her hips, she places them on her breasts, and squeezes, signalling you to do the same.

Glad for the distraction, you knead and massage them strongly, your fingers sinking into her soft flesh. Leaning up, you kiss each rib that you can find before your lips find the delicate little bumps of her areolas. Unbidden, your mouth opens and closes around her nipple, and you suck strongly. Nanny Mara moans sweetly, sounding almost like moos as you start to pump your hips.

The way her hole tries to shut itself around you is incredible. She feels far better than any woman you've been with, but Selas is far and away the absolute best. But that doesn't stop you from mercilessly pounding into her, enjoying the feel of another woman. Pinching her nipple between your teeth, you flick it with your tongue like a snake, when your mouth suddenly fills with warm liquid. You try to pull away in surprise, but Nanny Mara has crushed your head under her arms. "Don't stop! Just a little bit more!" She cries, before mooing loudly.

Lightning races across each and every cell of your body. As you gulp down mouthfuls of her thick and slightly sour milk, your muscles bulge and expand, and your feel your self growing larger. Your hips move faster and harder, pushing her forwards until her horns scratch out lines in her headboard. "I'm cumming, Mara. I'm fucking cumming!" You snarl, feeling a tremendous roiling build behind your cock.
