You fuck Diane's ass

As inviting as your sister-in-law's pussy is, her sweet little asshole looks just too tempting. You rub your shaft against her wet pussy lips and dip the head inside between her folds to lube yourself up. Then the look on her face turns from pleasure to surprise as you slip the head out and angle it downward, pressing against her tight back door.

"Wait... what are you... no...ooohhhoooOOWWW!" she screams in surprise and pain as your slippery cock pushes past the resistance and forces her sphincter open. She glares at you incredulously as you pin her down with your body, slowly sinking your stiff rod into her tight ass.

"I've never... had... aaahh... anyone... in there... aaAAaahh... before. Oh God, it hurts!" tears start to form in her eyes. "Why... ooohh... why... did you do that!... You fucker!... Oh fuck!" The pained expression on her face starts to give way to a look of **** pleasure. Her body relaxes and stops fighting against your cock. "Oh God, that feels... I didn't know oooohhh... it could feel... this good!"

You take that as your cue to slowly draw your cock back a few inches and gradually push back in. Her eyes squeeze shut as alternating waves of pain and pleasure wash over her expression. "Oh fuck, oh fuck, oh fuck, oh fuck, ow ow ow ow fuck ow ow oh ohh ohhhffffffuuuck ooOOHHHFFFFUUUUCK!" she says breathlessly as you work your penis in and out of what was a moment ago her virgin anus. Her hand reaches down her body. You look down to see her fingertips find her clit and rub it vigorously.

"OOOHHH FUCK YES! Fuck my ass, Dave!" she cries out, her whole body shaking as her first orgasm of the night hits her like a tidal wave. You feel yourself getting lost in the moment, no longer able to take it slow and gentle. You pump your cock deeper and deeper into her rectum with wild abandon. You feel your balls tighten as you go past the point of no return.

"Oh fuck! I'm going to cum!" you warn her.

"Then do it!" she tells you breathlessly.

Every muscle in your body contracts as you hang over the edge of your climax, then suddenly you erupt deep inside her, filling her ass with your hot cum. You roar triumphantly as her sphincter milks every last drop of semen out of you.

Diane looks like every nerve in her body is on fire with intense pleasure. "Oh fuck! Again! I'm cumming agaiiiiaaaAAHHHH!" she screams and bucks wildly underneath you. Her wild thrashing dislodges your cock which has already started to soften. She collapses on the bed underneath you and stares up into your eyes, her chest heaving with ragged breaths. Both of you are completely drenched in sweat.

"What the fuck were you... Oh God, that was so... I didn't know it was like..." she says between breaths. You can't help but grin at her. You love it when you fuck a woman so hard she can't finish her sentences.

You roll onto your back and lie next to Diane. She rolls toward you and lays her head on your chest. You wrap your arm around her shoulders and hold her as you both drift off into semi-consciousness.

"That was amazing," you hear Diane say, rousing you from a hazy half-sleep. She lifts her head and looks up at you. "but next time, you damn well better ask before you start tearing my ass apart, deal?"

"Deal," you tell her.

"Okay then," she says as she rolls away from you and climbs out of bed on unsteady legs.

"Where are you going?" you ask her.

"My ass is sore, I'm drenched in sweat, and I reek of sex. I'm taking a shower," Diane says as she ambles to the bathroom. She looks back at you when she reaches the doorway. "Do you want to join me?"
