omegas being fucked so good that their wombs cramp up as they’re being bred. like the cocks hitting their cervix so many times and for such a prolonged period of time that they start to bruise, if that’s even possible, but it’s very common for omegas toes to start curling as they cry out when their cervix is being pounded too deeply, the muscle cramping. it’s standard sex education that if an omega’s womb starts cramping it increases the possibility of pregnancy, so alphas should make sure to gently hold the omega down and continue, massage their lower tummies if they can to decrease the pain, but to not stop the knotting process. some omega’s are particularly fussy so they need to be held down by several alphas or tied up, but several alphas are preferable as being surrounded by many alphas makes the omega feel safe. they usually hold their arms and throat, murmuring gently and giving them fingers to suck while the alpha between their legs pummels their cunt. their ankles are tied to their thighs and held spread open and the alphas can see the sweet little baby’s toes curling and their back arching in discomfort as they start crying as their womb cramps, the alpha’s cockhead thumping against their cervix, squishing and pounding. they shush them and coo and rub their lower tummy, kneading and trying to ease the cramps, tell them it’s just a while longer, to just hold on a little bit, they’re almost done breeding them, they’ll be pupped soon. the alpha thrusts in for the final time and the omega’s eyes roll as the head of the alpha’s cock pops inside their womb, their cervix stretched and held open painfully and sweetly, the alpha’s knot in their cunt locking them in position. the alpha’s hold the sweet omega still as they tense up and cum, so the cock won’t be dislodged, the alpha spilling directly inside their womb. the sweet thing is weakly drooling and crying, eyes glassy as their tense body slowly grows limp, twitching as pain and pleasure mix together. when they’re sure the omega won’t hurt themselves and has adjusted to the pain, they carefully let go of their hold on them and allow the breeding alpha to cuddle the omega close. their cervix will be held open for the next fifteen minutes, and while it’s not the most comfortable, it’s necessary, and the omega will feel much better knowing the work paid off and everything caught and they’ll be properly pregnant soon. the omega is making soft helpless little sniffing sounds, whining and squirming, but the alpha licks their nose and peppers them with kisses, rubbing their lower tummy gently.
