C4T friends with benefits who've been hooking up for a few months, the trans girl hasn't wanted to have her cock touched so the cis girl has focused on other areas. Groping the trans girl's tits and thighs, pressing into her tummy and armpits, letting her suck on her fingers.
Tonight starts similar, a few minutes in the tgirl is whining and shuddering, this time she shakily looks up at her friend and asks "I-I-Is it okay if I take off my sh-shorts?"
Her partner nods "of course, if you're alright with that."
She nods back. "Y-you can look, um, if you want to." With that she gently pulls off the short but loose cotton shorts she's been wearing throughout each previous hookup. Beneath are her panties, pressed against her long, smooth cock. At it's tip a small, wet circle grows just under the waistband.
"I-It's really pretty, I-I hope that's alright to say." The cis girl says, biting her lip a bit.
"Y-yeah, that's okay, nice actually." Her friend blushes. Beneath her panties she throbs slightly. "Um, I, you've um, made me really feel like a girl, I guess. So um, I feel like you'll see this as part of a girl. Th-That's why I'm okay showing you."
Now it's the cis girl's turn to blush, "Th-Thank you, I'm, um, I'm honored; a-and, I'm really glad."
Her partner smiles, her cock throbs again, this time deliberately, "I-If you'd like you can touch it."
