Her ass

You pushed her down onto the mattress and lined your cock up with her ass.

"Ok," she moaned, "I was hoping you'd say that."

You pressed yourself in as Amy whimpered letting her ass swallow you. She'd made you cum twice yesterday and you were certain you were going to last this morning. You slowly worked yourself into Amy giving her deep strokes as she clung to the sheets.

"Faster," she implored.

You did as she asked to a grateful moan. She wasn't fully erect but as she went to stroke herself you pinned her hands down above her head.

"No no," you said, "we're practicing."

Amy whimpered, "then you're gonna have to fuck me really hard."

"Oh really?" you asked

Amy shivered as she fought against you restraining her.

"I need it," she pleaded, " I'm going to be **** to touch myself, you need to stop me, use me, I'm not your friend Amy, I'm just a hole."

"Safe word?" you asked.

"Refrigerator," she said, "you can hit me, **** me."

Your mind was swimming, you wanted to get started but you also wanted to make sure she enjoyed every minute of it.

"Anything I shouldn't do?" you asked.

"Don't call me Amy," she said, "be vulgar, and don't ask if I'm ok, if I cry or scream just know I'm loving it."

You took your belt from the floor rolled her onto her stomach and wrapped her arms up

"Strap in slut," you said shoving your cock back hard into her ass.

Amy squealed as you started to plow her into the bed, you slapped her ass hard and she cried out. With her lying prone you put one hand on the back of her head and **** her face into the bed as you fucked her. Anna had never wanted you to be too rough with her so this was all new to you. Amy's muffled moans were music to your ears as you used her tight little ass.

"You better not cum on my bed like this," you growled in her ear.

You rolled her onto her side and grabbed her neck squeezing as you fucked her. Amy smiled. After what you thought was long enough you let go and slapped Amy.

"No dozing off," you said.

Amy was very hard and as much as you wanted to touch her sweet little cock you didn't. You teased her nipple as she writhed against you.

"So sensitive," you said as she tried to roll away.

You pinched and she whimpered, you pinched both and she struggled against you and you gave them both a tug before letting them go as her eyes teared. You leaned down and took one of her nipples into you mouth running your tongue all over it before sucking it hard as Amy tried in vain to pull free. You moved to her other breast giving it the same treatment as Amy struggled.

"I bet you wish I was sucking you cock like this," you said.

"Please," whined Amy.

You slapped her ass hard leaving a red print on her pale skin.

"Holes dont beg," you said returning your focus to fucking her ass.

Amy's moans told you how much she was loving this treatment even as she struggled to free her hands. As you admired her you realized her cock was dripping.

"Is this precum?" you asked wiping some off with your finger and plunging it into her mouth as she eagerly sucked.

"Mhm," she said around your finger.

"I haven't even gotten started," you said as you pulled your finger from her mouth.

You thought back to a cruel trick Anna had for making you last and slapped Amy's balls. Her eyes went wide and her whole body tensed.

"You can cum when I say you can," you said.

You got her onto her knees facing away from you and **** yourself back in holding Amy's bound arms as you used her. Her deep pleasured moans returned and it began to feel like it had when she came last night. You slapped her ass hard and pulled you cock from her ass before slapping her balls again. She whined as her ass gaped trying to find some way to bring herself off. Amy had tears streaming down her face as you pulled her in for a **** kiss, she tried to rub herself against you to no avail.

"I think we've learned that I know just how to bring you to edge," you said, "practice is over, you can cum this time my sweet little slut."

You pushed her back onto the bed so her head was hanging off the side and once you were inside her you wrapped both hands around her throat as you fucked her as hard as you could. Amy moaned louder than you had ever heard through this treatment and as sexy as it was you were focused on the task at hand. She struggled hard but you held her down and squeezed a little tighter and as you did her ass squeezed you and she finally erupted, more than you had seen her cum yet. Her whole body shook as you fucked her through her orgasm and when she was finally done she shivered as you released her throat.

"Look at that you," you said admiring the mess she'd made on her stomach.

You scooped some up with your finger and put it into her mouth as she hungrily sucked it.

"Thank you," she sobbed, "thank you."

You kissed her and had she not still been restrained you were sure she would have hugged you. Taking a seat on the edge of the bed you had Amy climb onto your lap facing away from you and you let her ride you. Her slower more deliberate motion felt incredible and you loved watching your cock disappear up something so tight. You reached around and gently rubbed her cock and balls as she moaned in approval. You pulled her hair bringing her neck back for you to kiss.

"Get you a man who can do both," she sighed.

You rubbed just under the tip of Amy's cock and grabbed one of her breasts with the other hand.

"I can't," she breathed but as she protested she was pushing herself against your hand.

You undid her hands and she immediately grabbed the back of you head holding you to her neck and stroking herself with her free hand. You started to thrust into Amy and she moaned and tensed you grabbed her waist and started to go hard and soon Amy was moaning loudly. Amy shook violently as she spurted a few drops and you lost it holding her waist you hammered up into her ass pouring a torrent of cum into Amy. She collapsed against you as you finally finished, she was shaking and tearing up as you wrapped your arms around her and held her. You pulled out slowly and cum poured out of her ass but you weren't focused on that, you were focused on Amy who was shivering in your arms, tears running down her face.

"Amy," you started.

"Don't," she said, "it was exactly what I needed."

"You want me to run you a bath?" you asked, after particularly intense lovemaking Anna always asked for a bath."

"Mmm," replied Amy, "sounds perfect, very hot please."

You ran the bath and helped Amy to the bathroom. She smiled as she slid into the water. Unconsciously you did what you had always done with Anna stroking her leg as she closed her eyes.

"That was a lot of firsts for me," said Amy.

"Really?" you asked.

"Never done orgasm denial," she said, "never been slapped down there."

"Was there anything you didn't like?"

She sat and thought, "nothing I wouldn't do again "

You sat still rubbing Amy's leg as she let out a contented sigh.

"That feels nice."

You realized what you'd been doing and now couldn't stop.

"The end there," she said, "when you got more gentle with me, it was really nice."

She paused and looked away from you, "I haven't felt like that with a person in a while."

"It just felt nice to have you in my arms," you said.

"Guess it's nice having a friend with benefits," she said.

"Yeah," you said finally pulling your hand back, "I'll let you relax."

You went out to do your chores, your mind swimming. In one night with Amy you'd fallen into treating her like Anna. You were mad at yourself for trying to replace Anna but on the other hand Amy was nothing like Anna. Anna had been confident, proud. But then you thought more, Amy was confident when she realized she wasn't in danger, she was proud when she realized you wanted her. No, you told yourself, she made it clear you weren't anything but a friend with benefits or fuckbuddy to her.

You came back inside and put on a pot of coffee as you started making breakfast. Amy came out a moment later back in her large hoodie.

"Sorry," she said, "I was going to do that."

"It's fine," you said.

Amy sat down looking a little dejected and you paused.

"Amy," you said.

"I'm fine," she cut in.

You poured her a cup of coffee and she took it and retreated toward her bedroom.

"I'm not hungry," she said closing the door.

You were at a loss, what had you done? After cleaning up breakfast you needed to clear your head. You turned on the TV and wound up watching the news. There were a lot of laws being passed or pushed concerning transgender people, maybe that was what Amy was upset about.

You gave Amy her space but as it got late and she hadn't come out you decided to suck it up and knock on her door.

"Amy," you said.

She opened the door after a moment, her eyes were red and she was hugging herself. You had no idea what was going through her mind but you pulled her in and hugged her and she hugged you back tightly.

"What can I do?" you asked.

"Promise me you're not going anywhere," she said.

"I promise," you said, "you're stuck with me as long as you want."
