You hold her long enough to do something! (Requires 3% Strength)

She's not "strong", but she's a lot closer than you are. Even still, you manage to hold her in place just long enough to do a bit of damage.

Leaning down towards her chest, your hot breath escaping you and making its way down the front of Delilah's shirt, you take one of her nipples into your mouth. Her shirt's still on, so the feeling's less powerful than it would've been, but it's still something! Your mouth wets the shirt just over where he nipple is, and you suck at the material, taking a bit of air through. Delilah gasps, and her struggles momentarily stop, which lets you gently take the nipple (more than stiff enough to show through the shirt) gently between your teeth, rolling it side to side.

That does it! But that's also all you have time for, as Delilah's body kicks back into action and rolls you off and to the side, where she quickly mounts up on you. Her chest's rising and falling a little heavier than it was before, and there's a very noticeable wet spot right over her nipple. Hopefully that was enough....

Reaching down with her hand, she rubs the outside of your black school pants' crotch. You push your hand down to do the same.
