Amy wakes up first on Sonic's 27th birthday. It's 9 AM, and Amy feels that something is just a little off. Gently lifting the bed sheets, Amy sees that the sheets around her are soaked. She sniffs, and thinks over the various smells she knows. 'It's not Sonic… It's not sweat…' The pink hedgehog sniffs again, and her green eyes widen. Amy has figured out the smell. 'Oh no…'

Sonic rolls over and his emerald green eyes give Amy a confused look. "Everything okay Ames?"

Amy nods, blushing a little. "Kind of. First, happy birthday. Second, I'm a little worried."

Sonic frowns. "Worried about what, babe?"

Amy frowns. "Look at the calendar."

The blue hero does so. "It's a full moon tonight. I've heard it does some strange things."

Amy nods. "Yes, but I was hoping you'd catch on to the bigger reason I'm worried."

Sonic shakes his head, and Amy sighs. "Not only is it the full moon, but I'm in heat. Today is when I'm at maximum fertility."

Sonic's eyes widen. "Oh boy. I can see why you're worried. You tend to hump me at every possible chance."

Amy frowns. "Be happy it's only you."

Sonic chuckles and kisses Amy. "Believe me, I am. Now, I think Dash will eventually have to go to Tails and Cream's house so he doesn't get any bad memories."

The sakura hedgehog laughs, kisses her blue stud, and pulls on a red robe. Dash is already up and about, waiting for Mommy and Daddy to come play with him. After Sonic takes his shower, Amy takes one, barely resisting grabbing Sonic and dragging him into the shower with her. After her shower, Dash is bathed, dressed, and the three hedgehogs go to the Prower Residence.

-Tails and Cream's House-

Sonic knocks on the door. Cream opens it and immediately notices Amy. "You're going through that period, aren't you Amy?"

The pink hedgehog nods, then Dash speaks up. "What's Mommy going through?"

Sonic shakes his head. "You're not old enough yet."

Tails joins them in a few seconds. "Come on in guys. Cream's got some gifts for Sonic as well as some party games for everyone."

The hedgehog family goes inside, and the festivities begin.

-8 PM-

After a very long discussion about Tails' challenge, Sonic's gifts, and a lot of partying, Sonic and Amy vanish in a flash of blue light from the Prower Residence. Dash is once again staying the night at his uncle and aunt's house. Amy locks the door and then sees the full moon.

She feels Sonic's arms wrap around her waist and his deep voice in her ears. "Yes it's pretty, but not as pretty as you."

Amy turns around, her jade green eyes turning a pale green with lust. The kiss she puts on Sonic's lips nearly makes him faint.

The kiss breaks, and the rose-pink hedgehog's voice reveals how badly she wants her cobalt husband. "We need to get to our room. Now. Please Sonic."

Nodding, Sonic picks Amy up and bolts to their room. Once inside, Amy literally rips Sonic's blue shirt, blue jeans, and black speed shoes off of him. Sonic smiled, since he liked Amy's wilder side, but this was wild even for her. Since Amy was in heat, Sonic was about to have one of the most memorable nights of his life.

After Amy rips her own clothes off, she pins Sonic to the bed and handcuffs him. "I hope you took your endurance pills, my love. You're going to need them."

Sonic chuckles. "What, no foreplay?"

Amy touches her lower region and shows Sonic her soaked fingers. "I'm in heat Sonic. I don't need foreplay. But since you asked…"

Amy leans over Sonic and nibbles on his ear tips. Sonic begins purring and Amy trails her kisses down to Sonic's muzzle and neck.

Her green eyes look into Sonic's emerald eyes. "A little something extra for you."

Sonic gives a low moan as Amy bites his shoulders. It's a harder bite than Sonic would give her, since his skin is tougher, but the pleasure is there just the same. Amy loved Sonic's low growls, and soon she arrives at Sonic's nipples. The pink hedgehog doesn't even wait for Sonic to say anything. She just begins licking and biting her blue husband's nipples.

Sonic moans Amy's name. "Ohh Amy… That feels good."

Amy begins to suckle on Sonic's left nipple as she rubs his right one. More moaning from Sonic makes Amy switch nipples. Sonic attempts to hold Amy in place, but he can't because he's handcuffed.

Amy giggles at his actions. "Had enough foreplay?"

Sonic grins. "I don't think so. There's an area you haven't visited yet."

The sakura hedgehog gives a fake frown and turns to Sonic's 8 inch manhood. She begins stroking Sonic's member as her soft tongue teases the tip. There's a lot of loud clanging as Sonic writhes in pleasure. Amy is the only thing actually keeping Sonic on the bed.

The handcuffs are showing signs of breaking as Sonic's pleasure rises. "Amy! Please keep going!"

Sonic's noises make Amy's hormones reach an unknown level, and she begins deep throating all 8 inches of Sonic's organ. Sonic's moans get even louder, and Amy begins dry-humping Sonic on his abs, moaning loudly.

Their moans fuel their arousal even more, and Sonic is the first to make his announcement. "AMY! AMY I'M GOING TO CUM!"

Amy moans loudly, and after a few seconds Sonic unloads into Amy's mouth. As he orgasms, Sonic yells Amy's name. "AMY!"

Thanks to her heightened sensitivity, Amy tenses up in orgasm as well, moaning loudly. Turning to her blue stud, the rose-pink hedgehog swallows Sonic's entire load.

Sonic smiles. "That's always hot."

Amy nods and purrs into Sonic's ears. "Had enough foreplay, Sonikku?"

He thinks for a second. "Did I taste good?"

Amy giggles. "Of course. I wouldn't swallow your load if it didn't taste good."

Sonic chuckles. "Awesome. Well, we may continue. Can you take these handcuffs off now?"

Amy shakes her head, the long pink quills making Sonic drool. "Not yet babe. I'll release you when it's time."

Sonic nods, and Amy lowers herself onto Sonic's meaty manhood, moaning as all 8 inches fill her drenched womanhood. Once she's ready, Amy digs her claws into Sonic's shoulders and begins riding him. It's a hard fast pace as Amy's urges to mate take over her focus. Sonic entered that stage not long after she did, and gently thrusts upward into Amy as she lowers herself.

This makes Amy scream. "YES! DEEPER MY LOVE!"

Sonic nods and thrusts harder into Amy. She digs her claws deeper into Sonic's tough skin and thick fur as her second orgasm quickly approaches.

Her screams are fuel to Sonic's fire. "OH SONIC! JUST LIKE THAT! MORE!"

Sonic frowns. "You'll have to take the handcuffs off."

Amy shakes her head. "TOO BUSY MATING! JUST BREAK THEM OFF!"

Sonic sighs. "If you say so, sexy."

The chains to the handcuffs snap with no effort at all, and Sonic rolls Amy underneath him. His sakura wife's claws remain dug into Sonic's shoulders as her legs wrap around the royal blue blur's hips.

Sonic begins pounding Amy's flower at full speed, and it's only a few seconds before Amy screams into Sonic's ears. "SONIC I'M GOING TO CUM!"

Sonic smiles and gently bites on Amy's delicate shoulders with his sharp fangs. This extra bit of pleasure sends Amy over the edge.

Her luscious body shakes as she orgasms, and she screams Sonic's name at full volume. "SOONNIIIC!"

Sonic smiles down at Amy. Sweat has just begun to form on her fur, and her jade green eyes are sparkling with sexual satisfaction.

Sonic's deep voice makes Amy shiver. "This is why I had the soundproof glass installed."

Amy gave Sonic a kiss. "I'm glad. Now, I'm assuming you haven't cum yet?"

Sonic shakes his head. "Not yet, but I'm nowhere near finished yet, my love."

Amy smiles. "Then why are you still talking?"

Sonic moves to Amy's left nipple, dark pink and soft to the touch. Sonic's tongue snakes out and lightly licks the large nipple, making Amy moan loudly. "Oh yes Sonikku!"

Sonic begins to gently suckle on the nipple, making Amy shudder. He switches nipples, and Amy shivers as she feels the gentle suckling on her right nipple. She'd forgotten that Sonic was still inside her until she felt him start thrusting again.

Her moans border on screams as Sonic speeds up his thrusts. "Yes baby! Harder! Deeper! Faster!"

Nodding, Sonic suckles on Amy's left nipple again, rubbing the right nipple with his left hand, and rubbing her clitoris with his right hand.

His pace speeds up again, and Amy screams. "UH! UH! UH! OH WOW! YES SONIC! I LOVE YOU SO MUCH RIGHT NOW! FASTER!"

Again, Sonic rails Amy at full speed and power. Both hedgehogs are sweating and panting heavily now, but neither hedgehog cared. The full moon shone brightly on the two mating hedgehogs like a spotlight on a stage. Sonic and Amy just didn't have an audience.

Amy's hormones are pumping at full strength now, and she makes her announcement again. "UH! SONIC! I-I'M GOING TO-TO CUM AGAIN!"

The royal blue speedster shouts a reply to his sakura wife. "AH! ME TOO AMES! GET READY!"

Amy nods. "CUM INSIDE ME SONIC!"

Sonic gives a few more thrusts, then holds as his thick shaft pulses. His grip on Amy's shoulders tightens as he unloads into Amy's core, screaming her name. "AMY!"

At the same time, Amy shakes and draws blood from Sonic as her orgasm tears through her stunning body. Her warm juices spray onto Sonic's legs and lower abdomen as she screams his pet name. "SONIKKU!"

Sonic pulls out of Amy and flops onto the now-soaked blue silk bed sheets. Amy flops on top of him, and both hedgehogs inhale the scents. Sonic loved Amy's pheromones, and Amy loved Sonic's odor. The two pairs of green eyes meet, followed by a tender kiss.

Amy speaks first after the kiss breaks. "Mating with you feels (panting) SO much better (panting) without a condom, Sonikku."

The cerulean hero chuckles. "I agree. (panting) I'm hoping you're not (panting) done yet."

Amy giggles. "I'll let you know. (panting) I can't help that (panting) being in heat increases my endurance."

Sonic smiles. "I'm not complaining one bit."

The pink hedgehog kisses Sonic again, then gets on all fours, tail in the air. "You have another area my love."

Sonic gets the lube and climbs back on the bed. He lubes up his member, then lubes up Amy's tight anus. Tossing the lube onto the floor, Sonic positions himself behind Amy. "Ready honey?"

Amy nods. "I'm ready sexy."

Sonic nods and gently enters Amy's ample rear. She moans and shudders as all 8 inches fill her firm backside. "Ohhh yesss… I always love that feeling."

Once she feels Sonic's groin on her rear, Amy nods and Sonic begins thrusting. He gives Amy's rear a few spanks as he thrusts, and Amy moans. "Oh yes… Please, Sonic… Go faster."

Sonic nods and speeds up, reaching around and pinching Amy's large nipples. The sakura hedgehog tosses her head back, skipping the moaning and going right to the screaming. "Yes! Uh! Yeah! Harder! Deeper!"

Sonic chuckles. "I'll never get tired of your sounds, sweetheart."

Amy sighs as Sonic speeds up again. She manages one thought. 'The pleasure is so incredible. I knew Sonic was awesome in bed when we first made love nearly five years ago. He was great then, and he's still great now.'

Sonic has a thought of his own. 'It doesn't seem that long ago when Amy and I first got together. Looking back, I'm glad I grew a pair and asked Amy to be mine.' Amy and Sonic's hormones once again override their thinking.

Amy looks back to her cobalt husband. "UH! UH! SONIKKU! I'M GETTING CLOSE! AH!"

Sonic grunts his reply. "Me-Me too Ames! Here it comes!"

Giving a few more thrusts, Sonic holds as he unloads in Amy's ample rear. He pinches Amy's nipples as he shouts her name at a loud volume. "AMY!"

Sonic's pressure on Amy's dark pink nipples makes her orgasm yet again. Her juices spray onto Sonic's legs as she screams her husband's name. "SONIC!"

After their simultaneous orgasm passes, Sonic collapses onto the bed, and Amy gently lays her head on his chest. The pink and blue hedgehogs are sweating profusely and can barely breathe.

Amy's the first to speak. "Wow. (panting) I'm satisfied (panting) but I want more (panting)."

Sonic shakes his head. "I'm not sure (panting) I can continue Amy (panting)."

Amy's face has a playful look on it as her sparkling green eyes look into Sonic's shining emerald green eyes. "What's this? (panting) The incredibly skilled Sonic the Hedgehog (panting) can't go on? I told you (panting) that you should have taken (panting) your endurance pills."

Sonic chuckles. "I hope (panting) you're joking Ames."

Amy giggles. "Of course. I would still like you (panting) to pound me again though."

The blue speedster kisses his rose-pink wife. "I'll see what I can do. (panting) Which area should I start in?"

Amy assumes the position. "Start in my rear, babe. It always feels good."

Sonic positions himself behind Amy. Once his shaft is erect again, Sonic inserts himself back into Amy's anus. Amy moans loudly, then squeals when Sonic pulls her off the bed and leans her against him. Amy puts her head on Sonic's right shoulder, and he begins thrusting again.

Amy moans loudly and wraps her arms behind Sonic's head, kissing him passionately. Sonic returns the kiss and gently drags his claws along Amy's flat stomach up to her 36C breasts. Amy gives a loud muffled moan and takes handfuls of Sonic's long quills. The kiss breaks and Sonic once again bites Amy on her shoulders with his fangs. Amy's loud moaning makes Sonic smile, and he speeds up his thrusting into her ample backside.

Amy begins screaming as Sonic pinches her large dark pink nipples. "OH YES! FASTER! DEEPER! MORE DAMMIT!"

The royal blue hero laughs and goes full speed into Amy's tight anus. The screams that the rose-pink hedgehog is making drive Sonic wild inside, and it's not long before Amy tenses up.

Her body shakes as her next orgasm races through her body, and her juices spray onto Sonic's legs as she screams his pet name. "SONIKKU!"

As she orgasms, Sonic unloads into her rear yet again, also screaming her name. "AMY!"

After they finish climaxing, Sonic pulls out of Amy and helps her back on the bed. Joining her, Sonic snuggles up to his wife, panting. "Okay. (panting) I think (panting) I'm done."

Amy uses the Puppy Face on him, also panting. "Please Sonikku? (panting) I'll do all (panting) the work this time."

Sonic melts when Amy uses the Puppy Face. "Fine. (panting) But this is it for me."

Amy smiles. "Fine with me. (panting) I'm about done as well."

Amy's velvet lips press against Sonic's lips as she mounts him. She moans as she lowers herself onto Sonic's massive member. Once their groins connect, Amy begins riding Sonic again, but much gentler this time.

Sonic spanks Amy a few times, and Amy sighs with pleasure. "Please spank me again my love. It always feels good when you spank me."

Sonic spanks Amy a few more times, and Amy begins riding Sonic faster. Her moans get louder, and then Sonic begins thrusting upward as she lowers herself. "Oh yes! Okay! Get back on top! Finish us up Sonic!"

Sonic frowns. "You said you were going to do all the work."

Amy growls to him. "Just do it!"

The blue blur rolls his pink wife under him and begins thrusting at a fast pace. Amy's claws dig into Sonic's tough back and her legs wrap around Sonic's hips.

Her screams nearly deafen Sonic, but he doesn't care at this point. "UH! AH! OH YES! HARDER! FUCK ME HARDER SONIC!"

Sonic focuses his remaining energy and pounds Amy's womanhood at full speed and power, loving the squishy sounds he hears. Amy holds Sonic as close as she can, loving the penetration of his massive 8 inch shaft. Their lips meet as Sonic once again pinches Amy's large nipples.

The kiss breaks after a few seconds, and Amy makes her announcement. "SONIC! I-I'M GOING TO CUM A-AGAIN!"

Sonic manages to shout his reply. "ME-ME TOO AMY!"

Amy nods. "CUM INSIDE ME AGAIN SONIKKU! PLEASE! I WANT TO FEEL YOUR SEED ENTER ME AGAIN!"

Sonic thrusts a few more times, then unloads into Amy's drenched flower. He gives the soundproof glass a challenge as he screams Amy's name as loud as he can. "AMY!"

Just as she wanted, Amy feels Sonic unload inside her. Just after he orgasms, Amy reaches her final climax. Her claws draw more blood from Sonic as she shakes with the powerful orgasm. As she climaxes Amy screams Sonic's name at full volume. "SOONNIIIC! UH! WOW! Sonic! You-You just gave me another multiple orgasm… Four in a row this time. Oh wow."

Sonic somehow rolls Amy back on top of him, still inside her. He didn't care, and didn't have the strength to pull out of her soaked womanhood.

Amy sighed contently on Sonic's chest. "We haven't made love (panting) like this since… (panting)… Well, ever."

Sonic kissed the top of Amy's head as their scents began to work their magic. "That was incredible, Ames. (panting) Wow. I don't know (panting) what to say. Just wow."

Amy giggles. "I second those feelings."

The two hedgehogs share one last kiss and close their sparkling green eyes.

Sonic yawns. "Goodnight Amy Rose Hedgehog. I love you. So much."

Amy yawns now. "Goodnight Sonic T Hedgehog. I love you too, and happy birthday."

Sonic and Amy are quickly asleep, their bodies glowing with the love they share.
