After a few minutes of playing with the lucario, I decided to give her a break. I slid my cock out of her warm pussy, my cum dripping gently out of her opening, and she lay back on the ground, panting as she took time to recover, her fluffy tail twitching in the aftermath. I slowly pushed my still-slick cock into the next portal and was met by a very warm opening; I watched in satisfaction as the well-endowed blaziken gasped in indignation as my cock penetrated her. She glared at me as I pushed deeper, but couldn't help but moan softly in surprise at how large I was and she looked down and let out another moan as she saw her tummy bulge from my cock inside her. The machamp next to her smirked as she saw her friend give in to her desire so quickly, but I figured it would be fun to make them both submissive at the same time. I picked up the portal to machamp's vaginal lips, and withdrawing from the blaziken, slid my cock quickly into the machamp's pussy. Machamp's expression changed instantly from a smirk to a shocked embarrassed gasp, a deep red blush glowing in her cheeks. I smiled at her as I pounded her portal, her pussy as tight as weavile's had been but larger and warmer. Machamp continued to blush as her pleasure began to build, and she tried glaring at me but the quick thrusts I was using made her forget all about the indignity of the situation and she gave in, moaning as my cock massaged her g-spot. I withdrew from her and took a minute to take both portals, holding one firmly in each hand. I took the blaziken's portal and shoved my cock inside, pounding her quickly, making her yelp with surprise as I hit her g-spot again and again, thrusting relentlessly to her helpless cries, until she hit her first orgasm, her pussy contracting quickly around my cock as she climaxed. I let her finish and then withdrew, taking machamp's portal and pushing inside her pussy again, and did the same, pounding her as hard and quickly as I could, her short cries of pleasure music to my ears as I forced the powerful fighting-type to orgasm, machamp gasping for breath as her pussy massaged my cock with her contractions. Both pokemon panted as they recovered, and I smiled at them as they looked wide-eyed at me, not sure what I was going to do next.

I pushed my cock inside blaziken again, pushing even deeper this time, penetrating her cervix. She gasped in indignation as she felt my cock in her womb, but I wasn't done. I took my thumb and began to massage her clit; her eyes widened and she threw back her head and cried out in pleasure as my thumb continued to rub and play with her clit, and I took machamp's portal and bringing it to my lips, took her clit into my mouth and began to lick and suck; machamp moaned and sank to her knees as she felt me pleasuring her, shivering from time to time, as I licked her sensitive pleasure button. I felt the blaziken quiver as she neared orgasm, and I increased my attentions to her clit, rubbing and gently massaging, until she cried out in ecstasy as she came, her pussy contracting around my cock once again. The pressure was enough for me to finish for her, and I came with her, spurting my cum into her pussy even as I continued to taste the machamp's tasty juices lubricating her vaginal lips. I didn't release as much cum as I had for the weavile, but enough for her tummy to round out slightly. Her pussy was so warm I decided to stay inside while I got machamp ready for impregnation. I put both my hands on machamp's portal, and turned my full attention to her clit, stroking her little pleasure organ with long, firm licks, evoking loud moans of happiness from the now-tamed machamp. I felt her getting close as she began to gasp loudly, and I took one hand to pull blaziken's portal off my cock, cum dripping out of her pussy as I withdrew, and with both hands shoved machamp's pussy onto my cock, her back arching in surprise and pleasure as I penetrated her, sliding easily into her womb through her cervix, her tongue hanging out as she felt me so deep inside her, deeper than she ever thought possible. I chuckled as she drooled from the attention I'd been giving her clit, and I figured why stop there. I began to massage her clit even as I began to slowly thrust into her pussy once again, her pussy and clit so sensitive, I could feel her quiver with every thrust into her womb. The mewtwo's portal was positively soaked with aniticipation, and she looked over at me pleadingly, needing me inside her to give her the release that the other pokemon had gotten. I winked at her, and continued pleasuring machamp, her moans becoming louder as she approached orgasm, and she began to massage her four breasts with her hands as her pleasure mounted, making me even harder inside her as I saw her giving in completely to her desires. She began thrusting with her hips, my cock hitting the wall of her womb, and she moaned loudly as I continued to play with her clit, massaging quickly and firmly, thrusting steadily, until machamp finally reached her climax, and she gasped in ecstasy as pleasure washed over her, her pussy contracting around my cock, keeping me deep inside her. The visuals of her playing with her four F-cup breasts as she orgasmed was enough to send me over, and I gasped as I orgasmed, penetrating her cervix just as my cock began pumping my hot, thick cum into her womb, filling her womb completely, leaving her tummy slightly enlarged from the volume of cum I had deposited inside her. I sighed happily, really enjoying these mating sessions with these busty anthro pokemon. I looked over at the mewtwo, on her knees already, quivering, and figured I might as well finish strong.

The mewtwo's portal was so slick, I almost dropped it when I first picked it up. Mewtwo's clit was different than the rest; it was larger and rounder, and looked even more sensitive. I pulled out from the machamp's pussy, and she collapsed as I withdrew, in awe that she had been worn out and impregnated by a mere human.

I brought the head of my cock to mewtwo's clit, and began to massage, her clit so soft and slick against the sensitive head of my penis. We both moaned in pleasure as I continued to play with her, and I realized her clit was her most sensitive weakness, for it wasn't long before she reached a gentle orgasm, her pussy becoming slicker as I felt her quiver against my cock, her clit becoming slightly harder as her pussy spasmed in climax. She panted cutely as she recovered, but from the look she gave me, she wanted more. The busty mewtwo shuddered as she felt my cock enter her, and she gasped as I bottomed out inside her, filling her completely. I began to slowly thrust into her, her pussy so soft and slick. She let out soft, helpless moans as I slid in and out of her; watching me impregnate the other pokemon next to her had turned her on, and she wanted the same treatment. She read my thoughts, how the other pokemon fondling their own breasts was a big turn-on for me, and she began to do the same, squeezing and massaging her huge breasts as I continued my gently pace inside her, massaging her pussy slowly and firmly. My cock became even harder inside her as I watched her put on a show for me, and she sighed happily as her g-spot received the attention she had been longing for the entire time. I continued the pace of my thrusts, speeding up slowly as she continued to play with her breasts for me, and she moaned louder as she approached another orgasm. I thrusted harder, feeling her pussy quiver as her pleasure continued to climb, and my cock's length was enough to gently push through her cervix into her womb. Mewtwo gave a shocked cry and threw back her head, supporting her body with her telekinetic ability, as she orgasmed, the sensation of feeling me so deep inside her enough to send her over. As her contractions continued, I took the moment to pull out slightly to allow me to reach her clit, and she moaned even more loudly than any of the other pokemon had yet, as the gently rubbing of her clit caused another orgasm to rock her body, her pussy contracting wildly around me. The sensation of her contractions enough to send me over as well, and I gasped as I came, my cock's head flaring deep inside her as I began to pump my hot seed into her womb, fertilizing her eggs. I felt her using her telekinetic ability to massage my cock even more as it nestled inside her warm pussy, and I gasped as she forced me into another orgasm even as I finished my first, panting as the pleasure washed over my body. My cum continuing to spurt into her womb, her tummy rounding out as I filled her up with my seed.

I panted from the effort of having multiple orgasms in quick succession, feeling somewhat worn out by this last session. The mewtwo smiled at me with pleasure-bleary eyes, happy she would be bearing my children, rubbing her round belly happily. I smiled back and lay back in my chair, glad that I had completed my task. I couldn't wait to help out with the second set of experiments! I gently withdrew my cock from the mewtwo's vagina, most of my cum stored in her womb but some trickled out of her vulva as she relaxed.

I set down her portal and picked up the experimental design sheet, curious how things were going to progress with the next set of tests. I was confused however when I saw that the next set of tests required a human female to mate with male feral pokemon. But I definitely wasn't female; I figured they must have made a mistake.

Made a mistake that was, until I remembered they had recommended I bring a C-cup or larger bra...
